Description
Technical field
The present invention relates generally to trunk information, and especially, relate to a kind of method and apparatus that is used in the communication system trunk information.
Background technology
Wireless communication system is known in the art.In many these systems, remote communication units (wherein some unit can move at least) intercoms via the system infrastructure such as fixed location transmitter and receiver and/or mutually with other unit communication.Usually, wireless communication system is characterised in that corresponding communication range (its feature typically be transmitting boundary or range of receiving or this both), and the wireless communication ability of system infrastructure can not extend to outside this scope effectively.
Repeater also is known in the art.This equipment typically is used to extend the communication range (by extending emission and/or range of receiving) of given communication system.Via this mechanism, for example, lower powered relatively remote communication units can be efficiently with system receiver communication far away relatively, although this remote communication units is in outside the scope of this system receiver far away.This repeater usually operates in the automatic mode of independence, and repeats the emission information that it successfully receives.
Unfortunately, although there is multiple improvement project to system and remote communication units, but still there are such time and environment, promptly fail, receive the emission information of the communication unit in the given communication system communication range reliably with given required service quality level.There is multiple reason for this result, includes but not limited to, cover decline and other propagation problem.Performance requirement also may bring influence.For example, when continuing to increase, the data transmission rate demand (causes the increase of corresponding bandwidth continually), remote communication units in other the scope does not significantly increase the ability that successfully realizes required service level under the situation of transmitting power at the same time, and is weakened usually.Therefore, need a kind of method and apparatus that is used in the communication system trunk information, it is devoted to problem mentioned above.

Embodiment
The invention provides a kind of method that is used to realize the data transparency relaying, so that improve the performance of cellular system.In one embodiment, one or more relay stations are deployed in the sector of sub-district.These relay stations will be called as transparent relay stations (TR), and this is because for the viewpoint of the subscriber station in the sub-district, the present invention can operate this relay station in the mode of " transparent " almost in system.In one example, three TR can be disposed in the following position in the sector, and described position chosen being used for provides significant link budget improvement project to the subscriber station (SS) that is positioned at away from base station (BS), as shown in Figure 1.
In one embodiment of the invention, can select a plurality of TR (for example,, but only being the subclass in the TR sum in the sector), and instruct these a plurality of TR to carry out the relaying (or being activated) of specific SS more than one.In this case, selected TR monitors the uplink data transmission that (receiving and demodulate/decode) undertaken by SS.Then, Xuan Ding TR launches data again to the data recompile and being different from the channel resource that is used for original transmitted that SS uses (for example, different time slot, different subchannels, different spreading codes etc.).For the advantage of grand diversity (macro-diversity) is provided, can on identical channel resource, carry out (in this case from the emission of each selected channel, TR preferably with BS regularly and Frequency Synchronization, the emission near-synchronous ground from selected TR arrives BS thus).
A kind of method also is provided, has been used for when the data transmission of failing whenever selected TR correctly to receive/decode from SS, elimination is from the emission of any selected TR.This method relates to make channel resource allocating to the TR that is used to launch empty content.By this method, can make all TR in the sector become single group, to these all TR assignment group ID,, than sending order or the assignment that separates, can carry out SS to the group very effectively and monitor and the TR resource assignation like this to each TR such as multileaving group ID.When all TR in the sector are activated for specific SS emission, can predict, some TR SS emission (for example) of will correctly decoding near the TR of SS, and other TR can not be correctly decoded (for example, away from SS TR).Even in this case, effective grand diversity still can be provided, this is because at the channel resource that assignment is used for the SS data transmission for TR group, the TR that is correctly decoded the SS emission will together launch, and the TR of the SS emission of successfully not decoding will keep calmness.The important advantage of this embodiment is, when SS moves the leap sub-district, does not need " to switch to " another TR from a TR.On the contrary, the invention provides a kind of effective method, be used for automatically using the best TR of sector.
In another embodiment, instruct one or more TR to monitor the data transmission of a plurality of SS.For example, can provide the tabulation of connection ID (CID) to selected TR, and this means, instruct this selected TR to monitor uplink data transmission on all uplink channel resources of distributing to these CID.Also provide uplink channel resources to distribute to selected TR, it will be used by this TR, be used to launch the data that are received from SS (for example, launch again from SS data).A kind of efficient assigning method is provided, piece resource assignation to TR can be provided thus, and TR uses predetermined data arrangement rule, guarantee (for example to send identical data division on the resource that is transmitted in accurately identical correspondence from all TR, data segment from different SS), to guarantee being provided at the combination of BS place but not the grand diversity of phase mutual interference from the emission of a plurality of TR.Another aspect of the present invention is that data transmission rate can be different with the difference of SS, and the data transmission rate of being used by TR can be different from SS.In this case, by modulation and the code rate of considering to be used by the SS of relaying by just, and modulation and the code rate used by TR, BS can calculate the essential altogether channel resource allocation (referring to the example of this paper back) of the required TR of being used for.In this case, each selected TR preferably uses identical modulation and code rate, to keep grand diversity advantage.
In another embodiment, provide a kind of method, be used to select and regulate modulation and the code rate that is used to launch.
In another embodiment, BS will be stored in a channel resource set and go up the received signal from SS that receives, and the signal of storage will be made up with the received signal from the TR on the different channels resource collection.This provides another form of grand diversity, this be because, from the signal of SS and TR in the inner combination of BS, as the signal processing step.
The foregoing description can be combined, so that maximum comprehensive function to be provided.The multiple aspect of these embodiment and the aspect of additional embodiments have hereinafter been described.
Under the background of ongoing IEEE 802.16e Standardization Research plan, the detailed embodiment that hereinafter provides has been described.Although the OFDMA pattern to 802.16e has provided detailed solution, the present invention is equally applicable to other system.Listed initialism used herein in the table 1.

The tabulation of table 1 initialism
UL_MAP is the message that indicates the resource assignation on the up link.This message can expand to other information that are different from resource assignation that transmit, such as the information about adaptive antenna processing or uplink relay.
REG-REQ message is " register requirement " message.It is the message that SS sends after carrying out initial ranging.This message is the prerequisite before any data transmission, and passes through to send REG-RSP by BS, and perhaps " registration response " message is carried out affirmative acknowledgement.
Relaying technique above can be applied to the up link of IEEE 802.16e OFDMA.Have serious link budget problem on the up link, it has reduced uplink data rate and throughput of system significantly, even to rational radius of society (2km).Solution given here has realized the seamless introducing of simple single-hop relaying on the up link, is used to handle this problem.Downlink transmission has reduced the complexity of relay station thus significantly fully without relaying.
Solution given here has following advantage:
● transparent relay stations (T relay station) is a kind of unit of simplification, and it only needs to carry out the minimal set of small number of layers 1 operation and layer 2 task.And this relay station is not wired to network.
● relay processes is a kind of transparent process, and this process does not need to change SS, and only needs considerably less signaling to change, and is used to adapt to relay station and enables process.
● one or more T relay stations can be deployed in each sector.Specific T relay station does not need to understand other T relay station.
● BS always keeps the control to emission, has caused the launcher reliability that increases thus.
● this framework still allows to carry out hybrid ARQ (HARQ) on up link.
The difference of the PA power between SS and the BS is expected the people, can customize this solution, so that necessary help to be provided to up link, does not involve down link simultaneously.As a result, by producing the subordinate relation between relay station and the BS, can realize cost efficiency, allowing relay station is cheaply, has guaranteed the reliable emission with robustness by the central authority supervision simultaneously.Cost efficiency can realize that it only concentrates on the minimal set of layer 1 operation and layer 2 task thus by the complexity that reduces relay station.In addition, needn't relay and control message, only need relaying carrying data.And system deployment has been simplified in the configuration of transparent relay stations (T relay station).These T relay stations can be deployed in the existing sub-district, solving the up link covering problem, and needn't reformulate plot planning required when adding Microcell in order to realize identical purpose.
Fig. 2 shows the possible communication path between BS, SS and the T relay station.Fig. 2 A shows the typical communication path in the cellular system, wherein forbids the T relay station.BS inserts request by dispensing control information and arbitration, coordinates the resource in the sub-district.In addition, BS will carry data and be transmitted directly to SS, and receive direct carrying data from SS.Fig. 2 B shows the communication path of enabling the T relay station.In this case, BS still inserts request by dispensing control information and arbitration, coordinates the resource in the sub-district.In addition, the BS continuation will be carried data and will be transmitted directly to SS.Yet, allowing triangular paths from the up link of SS carrying data, this triangular paths is at first received and is detected by the T relay station, and then by T relay station recompile be transmitted into BS.Fig. 2 C and Fig. 2 d show two variation schemes of T relay station configuration.Fig. 2 C shows the s relay station of a plurality of activities, and this s relay station is retransmitted SS carrying data to BS simultaneously.That Fig. 2 D shows relaying and the not coexistence uplink communication of relaying the time.An aspect key of T relay station and very favorable is, SS is the existence of the relay station in the not understanding system fully.Other with the relevant up link function of control, such as range finding and bandwidth request, still handle to-BS path, so that simplify trunking plan by direct SS-.
On wide significance, process above is the required minimum requirement that is used to increase up link carrying data transmission rate.If can not use the T relay station, then data rate can not be considered relay station.If can use the T relay station, then data rate can be considered the T relay station, and data rate is very high thus.When each data transmission co-channel conditions adapted, condition can be such, even in the time can using the T relay station, if having enough quality with the direct link of BS, then can not use the T relay station.Typically,, determine whether to use the T relay station, can also determine whether to use T relay station (for example, consider and cover, but not decline fast) based on the average channel quality of long term to each emission.Provide by BS owing to distribute to the resource of the SS of T relay station link, so T relay station (more generally, one or more T relay stations) is a dependent repeater station.
Need the operation of execution
As previously mentioned, relay processes is fully transparent for SS, does not need to carry out extra operation thus.Yet, need the link between foundation and maintenance T relay station and the BS.Describe the implementation of the multiple-task that needs execution below in detail.
Network login and initialization
Network login is identical with traditional SS with initialization procedure, and difference is that at a some place (registration process), the unit must be identified as himself the T relay station.
The relay station assignment of carrying out at connection (monitoring)
The relay station assignment process is carried out frame by frame.To each T relay station (perhaps relay station group) assignment CID, need in the uplink portion of present frame, monitor the emission of this CID.Therefore, by UL_MAP is decoded, each T relay station has been understood its each resource that need monitor, and attempts detecting.Should be noted that the T relay station can monitor one or more connections (for example, one or more SS), and can become one or more multileaving groups' a part.For example, can be used to monitor two different connections by assignment T relay station, and this T relay station can be by different CID addressing (for example, if the T relay station activates, then by specific CID addressing, if perhaps this T relay station is the part among the relay station group who activates, then by multileaving CID addressing).
Replacedly, be different from the relay station assignment process of carrying out frame by frame, this assignment can be remained valid, until receiving assignment in the future or removing assignment.Perhaps, assignment can be in the time of scheduled volume (for example, 10 frames) effectively.
The communication of relay station assignment (emission)
Resource assignation from (one or more) T relay station to the emission of BS also is that frame by frame is carried out.Via existing UL-MAP_IE message, to each T relay station (perhaps T relay station group) assigned resources.Each T relay station only relaying those its successfully to the connection of data decodings.
The modulation/coding Scheme Choice
Because the T relay station is its successful back to connecting (backconnection) to data decodings of relaying only, so BS can begin to give SS with high MCS assignment when initial.T relay station monitoring link.If it can not be successfully to the data decoding, then it does not send any information to BS.Do not receive the BS of any information, it is too high understanding selected MSC, and subsequently to the lower MCS of SS assignment, receives some information from one or more T relay stations until it.This process is selected allowing to carry out initial MSC.After this initial MSC selected, the HARQ process can be selected by this MSC of fine tuning.
Replacedly, BS can be approximate based on certain open loop, carries out blind AMC and select.The straightforward procedure that MCS selects is to use and wish that SS approaches or positive (aggressive) default value of BS in some relay stations.System can depend on hybrid ARQ or emission again, is used to alleviate the AMC level of all unfavorable selections.
Replacedly, relay station can be eavesdropped on range channel, then to the base station report information.Relay station can use range channel to report this information.Perhaps, BS can reserve dedicated resources (supposing 1RE) be used for this process.For fear of the conflict between all relay stations,, and utilize the sign indicating number of institute's assignment that this report is carried out spread spectrum to each relay station assignment Walsh sign indicating number.
When only having a relay station, relay station can be carried on the back to carry to transmit has the MCS information of relay data.When a plurality of relay stations and RF combination, this solution is inapplicable.Relay station can send MCS on range channel increase request.Replacedly, CDMA embodiment mentioned above is suitable equally.And, can use certain type analog feedback (for example) by revising transmitter power, can support higher MCS with informing base station.
Relay station can also be at given time emission beacon, and SS can measure received power, and proposes the MCS request of himself.
The hybrid ARQ process
This framework can be suitable for the HARQ on the up link.T relay station (perhaps T relay station group) buffer memory is received from the data of SS.When the T relay station was successfully decoded to grouping, this T relay station sent data to BS on the resource of explicit assignment on the up link.If decoding is unsuccessful, then T relay station (perhaps T relay station group) is not launched any information.If do not receive any information, then BS understanding emission is unsuccessful, and sends the control of next HARQ emission.

And, in order to improve uplink data rate, can enable the transparent relay on the up link.For higher data speed and/or capacity are provided on up link, perhaps when SS when the link of BS has unacceptable quality, in the sub-district, dispose transparent relay stations (TR), so that SS is divided into the link of SS to the link of TR and TR to SS to the link of BS according to " favourable " principle.This process is fully transparent for SS: this SS does not understand it just by relaying.

The operation of chapters and sections 6.3.18 transparent relay stations
In order to improve the data rate on the up link, some uplink transmit of relaying is favourable.By the relaying on the permanent entity execution up link that is called as transparent relay stations (TR).BS can distribute one or more TR, is used for the data transmission that is associated with specific CID (for example, specific SS) on the relay uplink.This process has been shown among Fig. 3.In UL_MAP, uplink resource allocation is sent to the SS that launches, and comprise UL_TR_MONITOR_IE, be used to instruct TR or TR group to monitor same or a plurality of SS CID associated uplink emissions.In up link, SS launches, and TR monitors that assignment belongs to the emission of its supervision.TR carries out the demodulation sign indicating number to the emission that is monitored, these emissions can be by recompile with by emission (relaying) again in next frame thus.In next frame, in the 2nd UL_MAP message, each movable TR receives the resource assignation that is used for repeat transmitted.This resource assignation carries out each TR CID, or multileaving group TR CID is carried out.When each multileaving group TR CID is carried out resource assignation, can predict, the emission that relaying monitored simultaneously of these T relay stations, this provides macro diversity.
According to the identical exactly relative order of order that receives MAC PDU, from TR emission MAC PDU, and utilize and be addressed to the Modulation and Coding Scheme (MCS is based on UIUC) that indicates among the UL_MAP_IE of TR, this MAC PDU is modulated and encodes.The MAC PDU of each corresponding SS encodes separatedly, sends the situation that the separation of each SS of institute's relaying distributes as BS.If TR does not correctly decode from the data of specific user (CID), then they can not these data of relaying, and this part that makes assignment is for empty.
Provided the example of TR resource allocation among Fig. 4.In described example, TR must relaying three emissions: MAC PDU S1, MAC PDU S2, MAC PDU S3, their assignment according to previous frame in identical relative order present.TR receives its resource allocation (in UL_MAP_IE), is used to utilize three emissions of 64-QAM R=1/2 relaying, and receives necessary subchannel amount, is used to carry out operation of relays.Utilize the PDU of new MCS to want relaying, promptly MAC PDU S1 modulates and encodes, and a PDU is mapped on first resource.TR can not correctly receive MAC PDU S2, so it does not launch any information of S2, but makes the assigned resources of answering this PDU of relaying partly for empty.After the resource that is provided for MAC PDU S2, assignment is used for the resource of relaying MAC PDU S3.This TR resource assignation process makes BS can understand the relay data of where seeking each MAC PDU, even when the relay station use is different from the MCS of SS.When the identical CID of a plurality of TR relayings of assignment, also provide grand diversity.
