Embodiment
The clear definition that efficient MAC operates in the multicarrier environment according to the embodiment of the invention will help the bigger performance in the cordless communication network.Similar performance gain can be according to the embodiment of the invention to the message definition of the appointment of auxilliary carrier wave and activation and acquisition from the optimization that relevant travelling carriage (MS) economize on electricity and multicarrier are handled is instructed.
Embodiments of the invention are devoted to the management of a plurality of carrier waves: how to specify them, how to activate them, or the like.The distribution of auxilliary carrier wave usually is a dynamic process: depend on the factor such as the service quality (QoS) of channel condition and user's needs, can add more multicarrier and when no longer needing them, remove them then.Whether need them to depend on many factors, comprise the MS ability, for example can receive how many carrier waves, can transmit how many carrier waves, or the like.
Multicarrier type and operator scheme
In one embodiment, see that related carrier wave is one of two types (being main carrier and auxilliary carrier wave) in the multi-carrier operation pattern from the angle of MS.Main carrier is to be used for the carrier wave with the MS reciprocal exchange of business and physical layer (PHY)/MAC control signaling (for example MAC administrative messag) by base station (BS).The base station can utilize a plurality of carrier waves to dispose, but each MS only has a main carrier (it also is used) among the BS when MS operates in single carrier mode.That auxilliary carrier wave is that MS can be used for is professional, but only according to the particular command of the BS that on main carrier, receives and the additional carrier of rule.In multi-carrier operation, public MAC can keep MS mobility, state and contextually utilize the radio resource in one or more auxilliary carrier waves in the control fully through main carrier.
In some embodiments of the invention, main carrier and auxilliary carrier wave can both be supported customer service and control information this two, but main carrier serves as the anchor point of auxilliary carrier wave.Therefore; Except auxilliary carrier wave only the pattern of carries user traffic; Auxilliary carrier wave can also be operated in following pattern: in said pattern; Auxilliary carrier wave carries some in their the in-band signalling control information, for example mixed automatic retransmission request (HARQ) and channel quality (CQI) feedback, regularly in advance and power control.Simultaneously, for example be used to switch, the signaling of the more robust of paging, fail safe, mobility, MS condition managing or the like usually (at least in certain embodiments) handle by main carrier.
For instance, in certain embodiments, auxilliary carrier wave is used to the bandwidth of expanding system so that to the user higher data rate is provided, so it comprises that the supplementary service channel that is used for the user and some in-band signallings are to keep those channels.In some cases, some in those inband signaling links (for example some feedbacks) also can be transmitted on auxilliary carrier wave.If on auxilliary carrier wave, receive data, then feedback can not be sent out on identical carrier wave.Replace, can on main carrier, send feedback, this feedback statement is receiving data on the main carrier and on auxilliary carrier wave.In such embodiment, in other words, will be not can not send feedback on the two at the auxilliary carrier wave of advocating peace.But, main carrier will transmit indication be on the main carrier, on auxilliary carrier wave, or receive the single feedback signal of data on the two at this.
In at least some embodiment, main carrier is in charge of MS.For example, main carrier instruct MS get into dormancy, get into idle, carry out handover operation, or the like.Main carrier can also activate additional auxilliary carrier wave, thus expansion effective bandwidth.Therefore can on a plurality of carrier waves, have and distribute and resource.Change kind of a mode and say, in these embodiment, under the guidance of main carrier, can dynamically open and close auxilliary carrier wave; Be held with always being connected of main carrier.
Based on main and/or auxilliary the use and destination service, the carrier wave of multicarrier system can be configured according to different modes as follows:
The carrier wave of configuration fully: a kind of Independent Carrier Wave, to this carrier wave, configuration comprises synchronously, all control channels of broadcasting, multicast and clean culture control signaling.The carrier wave of configuration is supported single carrier MS and multicarrier MS this two fully.
The carrier wave of part configuration: configuration is used for the only downlink carrier of up link (UL) carrier wave that matches of the carrier wave or in fdd mode, not have of the transmission of down link of TDD.Additional carrier wave so only can combine main carrier to be used, and can not serve with the IEEE 802.16m that is provided for MS by independent operation.Carrier wave is that the senior lead code that can use carrier wave that dispose fully or the part configuration is indicated.In at least one embodiment, MS should not attempt the carrier wave that network got into or switched to the part configuration.
Main carrier disposes fully, and auxilliary carrier wave can depend on deployment scenario but configuration wholly or in part.The auxilliary carrier wave that is used for MS, if dispose fully, then can be as the main carrier of other MS.Each a plurality of MS with the main RF carrier wave of difference can also share identical auxilliary carrier wave.
Consider following embodiment: wherein all carrier waves dispose fully, and promptly wherein each carrier wave is self-contained, and can carry their signaling.If BS has two carrier waves, i.e. carrier wave 1 and carrier wave 2, then first user can use carrier wave 1 as its main carrier and use carrier wave 2 as its auxilliary carrier wave.Second user can use carrier wave 2 as its main carrier and use carrier wave 1 as its auxilliary carrier wave.If the bandwidth that first user need add, then carrier wave 1 and carrier wave 2 this two can be exclusively used in first user, and in this case, carrier wave 1 is still main carrier, and carrier wave 2 is therefrom to have used resource so that increase the carrier wave of the first user's data speed.Equally, in this embodiment, each user's main carrier is that the user always gets back on it and uses it for the carrier wave of the broadcasting supervision, paging or the like of any kind of.Auxilliary carrier wave has only surpassed with exchange and has been used when MS utilizes the supplementary service of the business that main carrier can deal with when the user is in connected mode in service condition.
Following multi-carrier operation pattern is identified, and they can all or independently be supported:
Multi-carrier polymerizing: a kind of multi-carrier mode wherein keeps its physical layer connection in the data of MS on handling auxilliary carrier wave and keeps watch on the control signaling on the main carrier.Can cross over a plurality of auxilliary RF carrier waves of advocating peace to the resource allocation of MS.The link adaptation feedback mechanism should combine and auxilliary this two the relevant measurement of carrier wave of advocating peace.In this pattern, system can specify auxilliary carrier wave to MS at down link and/or up link based on system load (promptly being used for static state/dynamic load leveling), peak data rate or qos requirement asymmetricly.Polymerization refers to, and receives main carrier and receives the auxilliary carrier wave reception of main carrier (and do not disturb) then simultaneously.This pattern possibly need MS to have a plurality of receivers.This is called as polymerization, because professional physically polymerization of quilt on a plurality of carrier waves.If for example each carrier wave has the bandwidth of 20 MHz, then the effective bandwidth after polymerization will be about 40 MHz.
Multicarrier switches: a kind of multi-carrier mode, wherein MS switches to auxilliary carrier wave with its physical layer connection from main carrier according to the BS instruction.MS at the appointed time is connected with auxilliary carrier wave in the section (for the time period that BS knew), and turns back to main carrier then.When MS is connected to auxilliary carrier wave, do not need MS to keep its physical layer to connect to main carrier.This pattern can be used for broadcast/multi broadcast or other unicast services, to be used to switch to the carrier wave of the part configuration that is used for the only service of downlink transmission.For instance; If will send big file; But expectation avoids letting the bandwidth on the current carrier wave of this traffic limits, then can proceed to the switching of different carrier, and provides instruction to download and in (for example) 10 milliseconds, turn back to main carrier then to accomplish.BS knows that other carrier waves are used in those 10 milliseconds, and MS knows during those 10 milliseconds what is done.
Main carrier changes: a kind of multi-carrier mode, wherein BS changes the main carrier of MS.This mode class is similar between Fast carrier and switches, between Fast carrier, switching, and only PHY change in the maintenance MS control on identical MAC.This multi-carrier mode is all MS needs.Main carrier changes pattern and possibly relate to not carrying out under the situation that complete network level switches main carrier and be changed from carrier wave 1 and be carrier wave 2.In this case, said change is local for the base station, rather than handles at network level, and this is because said change only is to change to another from a radio frequency.Control fully from a carrier wave and forward another carrier wave to.From the upper strata, said change is to break off connecting.From lower floor, said change is along with line: become 20 MHz channels or become another 20 MHz channel from 20 MHz channels from 10 MHz channels.
Below be that all multi-carrier operation patterns are common:
System definition N RF carrier wave that independently disposes fully; Each carrier wave utilize all synchronously, broadcasting, multicast and clean culture control signaling channel be by configuration fully.Each MS in the sub-district is connected to only in the carrier wave that disposes fully that is designated as its main carrier, and its state is controlled through said only carrier wave.
This system can also define the RF carrier wave of the individual part configuration of M (M >=0), and it can only be used as in company with main carrier auxilliary carrier wave together, to be used for the only transfer of data of down link.
The set of the radio carrier of all supports is called as available carrier wave among the BS.
A plurality of carrier waves can be in the different piece of same frequency spectrum piece or in non-adjacent frequency spectrum blocks.Support to non-adjacent frequency spectrum blocks possibly need the additional control information on the auxilliary carrier wave.
Except information, support the BS of any multi-carrier mode also to MS some essential informations about other available carrier wave to be provided through such main carrier about (service) main carrier.Basic multicarrier configuration notifies existence, bandwidth, duplex and the position of all available carrier wave in frequency spectrum to prepare any multi-carrier operation to help MS to MS.Main carrier can also provide the extend information about the configuration of auxilliary carrier wave to MS.
The MAC operation
To the MAC of multicarrier operation identical with to single carrier mode, and message carried to each MS and quilt on main carrier, only if regulation is arranged hereinafter in addition.
Network gets into
Network in the multi-carrier mode gets into identical with single carrier mode, and wherein MS and BS also indicate during capability negotiation them to the support of multi-carrier mode.MS can only utilize the carrier wave of configuration fully to carry out network and get into (or network gets into again) process.In case MS detects A-PREAMBLE on the carrier wave of configuration fully, then MS can continue to read the system parameters and the system configuration information of superframe head (SFH) or expansion.
During initial network gets into, MS will notify its support to multi-carrier transmission to BS through REG-REQ message, and BS will whether it supports any multi-carrier mode to this MS indication through REG-RSP message.The dibit sign indicating number is used in basic multi-carrier capability exchange in having the REG-REQ/RSP message of following indication:
| b1，b2 | Multi-carrier capability |
| 00 | No MC pattern |
| 01 | Multi-carrier polymerizing |
| 10 | Multicarrier switches |
| 11 | Multi-carrier polymerizing with switch this two |
After network the gets into initialization MS of being used for according to the embodiment of the invention is illustrated at Fig. 1 with the process of preparing follow-up multi-carrier operation according to the embodiment of the invention.This process comprises:
The multicarrier configuration of acquisition available carrier wave at the BS place
Acquisition comprises two steps about the information of designated carrier:
1. provide about supported carrier wave of MS and their combination multicarrier information configured to BS.
2. obtaining can be in the information to the subclass (being called as designated carrier thus) of the available carrier wave that utilize in the follow-up multi-carrier operation of this MS about BS.
Before designated carrier was activated according to the guidance of BS, MS such carrier wave is not carried out any MAC or PHY handles.Network gets into the basic multi-carrier capability negotiation during process (it is identical with the process that is used for single carrier mode) is included in REG-REQ-RSP.Still with reference to Fig. 1, piece 110 refers to the connection that foundation is supplied.Piece 120 confirms that such connection is operational.
In piece 130, whether generation supports the inquiry of public multi-carrier mode about MS and BS.If answer to not, then continue to handle (140) according to the single carrier process.If answer to being, and MC-CONFIG-ADV message is received (150), then sends the MC-REQ (160) that comprises the multi-carrier capability negotiation.But, then handle turning back to the just point before MC-CONFIG-ADV receives inquiry if answer to being also not receive MC-CONFIG-ADV.
After the transmission of MC-REQ, receive MC-RSP, it comprises the tabulation (170) of designated carrier.MS and BS are ready for multi-carrier operation (180) then.
MS obtains to be used for the MC configuration of available carrier wave
Though broadcasting is about the information of radio configuration of service carrier wave on SFH, at least one embodiment, BS should be provided at the basic radio configuration of other available carrier wave among the BS to MS through MC-ADV message.This message is periodically broadcasted by BS, and it comprises the configuration that multi-carrier mode and BS support.In multi-carrier configuration information and any multi-carrier mode or all MS in the single carrier mode relevant and can use by it.About the information of available carrier wave under situation identical on the whole network, network can be when initial network gets into provides such information with the part as supply to MS, and MS can store and use this information, up to network renewal is provided.
MC_CONG_ADV (multicarrier configuration announcement) message: at least one embodiment, BS should periodically broadcast MC-ADV message and receive for all MS.This message comprises the information such as centre frequency, dual-mode, bandwidth and other parameters (if being different from the service carrier wave); And it is that also each carrier wave specifies physics carrier index, and said physical carrier index is quoted any of any available carrier wave being used for by BS and MS use.Configuration information is applicable to all MS.
Following parameter can be contained in the MC-ADV message that is used for each available carrier wave:
The physical carrier index
Centre frequency (for example band class index and channel indexes)
Channel width
Carrier type (traditional mode only, fully/the part configuration)
Dual-mode
Main preamble index
Auxilliary preamble index
Delivering power
Can be omitted to reduce expense with the identical information of information that is used to serve carrier wave.
Acquisition is about the information of designated carrier
After capability negotiation, and if BS confirm availability to the multicarrier characteristic of MS, then MS can ask BS with the information of acquisition about designated carrier through MC-REQ (multi-carrier requests) message.Designated carrier is can be potentially to be used to be used for the subclass to the available carrier wave of any follow-up multi-carrier operation of this MS by BS.MS comes the request of MS is responded through MC-RSP (multicarrier response) message.
MC-REQ (multi-carrier requests) message: multi-carrier requests message sends to the tabulation of BS with the request designated carrier by MS.In at least one embodiment, this message should comprise all information of the multicarrier configuration of supporting about MS, and wherein BS needs said multicarrier configuration to decide to MS to specify which carrier wave or their combination and activate when needed.
Below be the parameter that should be included at least one embodiment of the present invention in the MC-REQ message:
MS multi-carrier capability and restriction
Maximum carrier wave in DL/UL
Maximum spacing between the carrier wave
The tabulation of candidate's designated carrier
Support to the transfer of data on the protection subcarrier.
MC-RSP (multicarrier response) message: based on the information that MS provides on MC-REQ, at least one embodiment, BS should respond so that the information about its designated carrier to be provided to MS MS through MC-RSP message.In at least one embodiment, below be the parameter that should be included in the MC-RSP message:
The tabulation of designated carrier
Be used for the additional/detailed MC configuration (optional) of designated carrier
Support to the transfer of data on the protection subcarrier.
MC-RSP is sent to MS by BS in response to MC-REQ message usually, upgrades the tabulation of designated carrier but it can also be sent to MS.The order that carrier wave occurs in MC-RSP message can be used as the logic carrier index and the follow-up of designated carrier quoted being used for.Replacedly, the physical carrier index that in MC_CONF_ADV message, provides can be used to such addressing.
Bandwidth request and resource allocation
All bandwidth request are all used designated bandwidth request channel, are followed with the identical process that defines to single carrier mode and transmit on the main carrier of MS.Can on (one or more) auxilliary carrier wave and main carrier, in MPDU, transmit according to single carrier mode and use the incidentally bandwidth request of transmission (piggyback).
When receiving bandwidth request, BS can distribute the down link or the uplink resource of the combination that belongs to specific carriers or a plurality of carrier waves.Multi-carrier resource appointment to carrier aggregation can be used the AMAP-IE identical with single carrier mode, and wherein the A-MAP message to each active carriers is transmitted in corresponding carriers.
Replacedly, special multicarrier AMAP-IE can be used and be transmitted on the main carrier in identical composite information element, to cross over the auxilliary allocation of carriers resource of advocating peace.
Service setting/change message (being DSx message) only transmits through the main carrier of MS usually.Service flow is to public MAC entity and defining, and the QoS context of the MS that is represented by SFID is applicable to the auxilliary carrier wave of main carrier and (one or more) and jointly is applied to all carrier waves of MS.
DL CINR reports operation
BS can specify the CQI channel to each carrier wave of MS.When the CQI channel was designated, MS reported the CINR that is used for carrier wave through the specified CQI channel of corresponding carrier wave.When REP-REQ/RSP message was used to DL CINR report operation, said message was transmitted on the main carrier of MS.REP-RSP message can comprise the CINR report that is used for each carrier wave all carrier waves or that be used for MS.
The CINR that can instruct MS not send to auxilliary carrier wave measures (if their signal quality is lower than threshold value); In this case; BS will avoid on so auxilliary carrier wave, sending data, is enhanced up to signal quality to be higher than threshold value and MS and to restart on this auxilliary carrier wave, to send CINR and measure.
Handoff procedure
MS follows to the defined handoff procedure of single carrier mode.In at least one embodiment, transmit through main carrier with switching (HO) related all MAC administrative messags.
During the HO preparatory stage, when BS receives the HO-REQ message from MS or when BS when MS sends HO-CMD message, BS can with the information of possible target BS exchange multi-carrier capability.This information comprises available carrier wave number, carrier aggregation or the carrier wave switching capability of MS.
When renewal identifies the information of (for example station identifier (STID)) or security context about the MS at the target BS place in advance between the preparatory stage at HO, can use HO-CMD message multicarrier relevant information (for example auxilliary carrier wave) to be provided to MS.
After confirming to switch to target BS, the network that MS utilizes selected carrier wave to carry out it gets into again, and wherein selected carrier wave becomes the main carrier of MS at the target BS place.If auxilliary carrier wave is not offered MS in advance, then target BS can distribute auxilliary carrier wave or connection can become single carrier mode during network gets into again.
Park mode
When MS got into park mode, MS and BS consulted its park mode parameter (being the configuration of sleep window and listen window).Park mode be applied to MS through negotiation parameter, and according to the park mode parameter through consulting, all carrier waves are electricity (power down) down.
Idle pulley
MS confirms that default carrier wave is to keep watch on paging and other broadcast control messages with single carrier mode similarly.In idle pulley, the carrier wave of selecting like this is the main carrier of MS, only if changed by BS.
Being used to initiate the message of idle pulley and main carrier that process is utilized MS handles.During the paging listening interval, MS keeps watch on the beep-page message on its main carrier according to single carrier mode.When paged, MS utilizes main carrier to carry out network and gets into process again.
Auxilliary carrier management
The process of carrier management relates to the exchange of the MCM-DIR/MCM-CONFIRM message between BS and MS, to begin, to stop or in related multi-carrier operation pattern and carrier wave, making a change.These message realize the auxilliary carrier wave activation in the multi-carrier polymerizing and deexcitation, main carrier change or the master is switched to auxilliary.
Auxilliary carrier management refers to the activation and the deexcitation of carrier wave, and this causes the beginning that multicarrier is handled at the MS place and stops.The activation or the deexcitation of (one or more) auxilliary carrier wave are decided based on loading condition and other factors of qos requirement, carrier wave by BS, and indicate to MS through MCM-DIR MAC administrative messag.
The auxilliary carrier wave that is used for polymerization activates
The activation of the auxilliary carrier wave in aggregation scheme is to exchange through the MCM-DIR/MCM-CONFIRM between MS and BS to carry out.BS sends MCM-DIR MAC administrative messag and comprises following information on main carrier:
Carrier index table (logic carrier index) and for each carrier wave
Type of action: (activating or deexcitation)
Multi-carrier operation: (polymerization, switching)
Be used for the Optional Field that the feedback channel on the main carrier distributes, send channel feedback (if such carrier wave is not to dispose fully) about the auxilliary carrier wave that activates for MS
Combination feedback (ON/OFF) on the main carrier
Scope: STID or flow identifier (FID).If STID MC pattern goes for any service/connection to this MS.
In response to MCM-DIR MAC administrative messag, MS transmits MCM-CONFIRM MAC administrative messag through main carrier.This message confirms to BS, and MS is the carrier wave in MCM-DIRECT message, listed of activation successfully.
When receiving assignment messages on the carrier wave that MS prepares activating, send affirmation by MS.After BS received MCM-IND MAC administrative messag, BS can begin on the auxilliary carrier wave of such activity (one or more), to transmit assignment messages and data with single carrier mode similarly.
BS can be the auxilliary allocation of carriers fast feedback channel of each new activation on MC-IND message.MS can report the CQI to the auxilliary carrier wave of all downlink activities.MS can carry out the Perodic ranging (ranging) to the auxilliary carrier wave of uplink activities.When being assisted carrier wave by the BS guidance to be used for uplink activities, sounding channel also can be transmitted by MS.MS can upgrade the system information of all movable auxilliary carrier waves, and can keep watch on the resource allocation message to the auxilliary carrier wave of all activities (one or more).
Fig. 2 combines above description that initiation and the termination of handling according to the multicarrier at the MS place of the embodiment of the invention is shown.
Main carrier changes
From the purpose of load balancing, the variation channel quality or the other reasons of carrier wave, BS can come instruct MS that its main carrier is changed into one of complete allocation carriers available in identical BS through the control signaling on the current main carrier.MS switches to the carrier wave that target disposes fully specified operate time at BS.This carrier wave changes and can also be asked through the control signaling on the current main carrier by MS.Suppose public MAC management service and target main carrier this two, then need not get into process again at the network at target main carrier place.BS can provide the system information of the target main carrier different with serving main carrier via the service main carrier.BS can distribute new STID when current STID is provided by another MS.The logic carrier index can be arranged again.BS can not carry out instructing MS to change main carrier under the scan condition.
BS can instruct MS carries out the scanning to other carrier waves of not serving for MS.MS reports back scanning result and gives serving BS broadcasts that said result can be made by BS and be used for confirming the carrier wave that confession MS switches to.In this case, be not the MS service if target carrier is current, then if necessary MS can carry out with target carrier synchronously.
The carrier wave switch mode
When auxilliary carrier wave is the part configuration, be supported in the multi-carrier mode main to auxilliary carrier wave switching.It can be periodic that carrier wave between main carrier and auxilliary carrier wave switches, or utilizes the defined timing parameters of multicarrier switching message on the main carrier to carry out Event triggered.When MS switches to auxilliary carrier wave, its main carrier can provide such as regularly with the frequency adjustment essential information synchronous fast with help MS and auxilliary carrier wave.
Fig. 3 is the flow chart for preparation method 300 of initialization travelling carriage with the multi-carrier operation of base station in wireless communication protocol that illustrates according to the embodiment of the invention.
