Background technology
Coordinated multipoint transmission (CoMP) is a kind of technology for strengthening performance for mobile subscriber (such as subscriber equipment (UE)), and method is to be incorporated in different communities and the uplink signal that may process in different special ICs (ASIC) or the base band card of particular UE.Performance gain is to be received from the uplink signal of mobile subscriber by multiple different districts, is then incorporated into together by the Serving cell belonging to mobile subscriber.Folding is probably joint-detection complicated homophase and four phases (IQ) data (domain samples) or merges soft bit (log-likelihood ratio (LLR) data).CoMP technology is proposed to be used in (such as) Long Term Evolution (LTE) and senior Long Term Evolution (LTE-A) communication system.
Significant challenge during application CoMP is that user data needs at full speed to transmit with the mode of low latency between the processing unit and the processing unit of Serving cell of cooperation cell.Processing unit is likely located on same ASIC, in the different ASIC on same baseband board, on different baseband boards, or on different website.It is essential that application CoMP can not increase the restriction of maximum allowable system delay.

Base band framework can have various ways according to system requirements.Base band framework can build and improve motility for farthest, i.e. the software configurability of height, this often means that DSP is the most frequently used processing unit.
Base band framework can also optimize performance, that farthest reduces power consumption or ASIC takes up room (i.e., the desired zone of chip/silicon), this is equivalent to a kind of more with hardware accelerator for the base band framework guided, and in most of the cases can reduce the motility of base band framework.
In base band framework, the selection of processing unit also further depends on the chance of parallel processing.If intrinsic algorithm can be used for parallel processing, then good solution may have multiple process node run parallel with relatively low clock speed, and wherein individual node performs algorithm in order with high clock speed.
When for advanced communication system (ACS) (such as LTE) exploitation base band framework, mass data needs to be processed by multiple processing units, and these data need to transmit between the processing unit in baseband system.When adding CoMP technology for meeting system service requirement, these from multiple communities data need by baseband processing unit Combined Treatment, these processing units need not juxtaposition on same ASIC.Therefore, with regard to postponing and for bandwidth aspect, up-link CoMP is implemented very challenging.Therefore, it is necessary to provide specialty solution for the problems referred to above.

Detailed description of the invention
Delay needed for the high speed data transfer being as noted previously, as in cellular radio Communication system between different processing units and bandwidth requirement, implement up-link merging data and process the most challenging.
Demodulating uplink signal in (such as) LTE system is an extremely complex process, wherein needs to perform substantial amounts of signal processing for each subframe in only 2.35ms.If added to by CoMP in demodulating process, then still in the time span IT processing procedure of 2.35ms, thus the requirement postponed must be met.Challenging part is that from a processing unit, data are transferred to another processing unit.In order to not violate delay budget, the bandwidth requirement between processing unit needs about 10Gbps the most.
The most effective solution can be that each ASIC provides high-speed interface, has enough abilities without departing from delay budget.But the interface being to provide this type of high bit rate can consume high power equally, and takies substantial amounts of silicon area, it means that will implement this type of solution sufficiently complex and expensive.Such as, will reach required bandwidth, a large amount of high speed serialization links (possible 4-8) need parallel running in same system.
A kind of alternative method that may consider is the Base-Band Processing of all Resource Block of juxtaposition, and wherein CoMP is applied on same ASIC, and the RB that CoMP is not applied to will be processed by its original cell.Do so can provide some advantages reducing interchip communication (i.e. transmitting data between two or more phy chip/ASIC) aspect, particularly in the case of CoMP Interference Cancellation (IC), but still have and much be initially accomplished by transmitting the data carrying out processing.Additionally, due to the mobile subscriber belonging to different districts transfers to other, therefore this scheme also can increase the complexity of level L2 and L3.
But, the solution that the present invention provides can be relaxed when transmitting data between two or more base stations high bandwidth and the requirement of low latency, serves each community, and does not has the defect of prior art.
Demodulation/decoding process in LTE can be divided into multiple step.First it is antenna processing (AP), estimates including OFDM demodulation and channel.This separately will complete for each antenna.After antenna processing completes, receive frequency domain I/Q data from each antenna, and these data are performed equilibrium treatment and decoding.If eliminating antenna processing, demodulation/decoding process can be divided into three steps, as shown in Figure 1:
Demodulation step (DM1) for the first time: for each mobile subscriber, performs equilibrium, IDFT conversion and demapping, becomes the LLR value constituting transmission block frequency domain data.Afterwards, transmission block carries out release of an interleave, solves rate-matched and turbine decoding (DC).Performing crc check on transmission block, if transmission block is correct, it will be transmitted to the more high-level of system.Demodulation step will export hard bit and soft bit for the first time.
Regeneration step: if CRC is incorrect, receptor may determine that execution second time iteration transmission, and referred to as Advanced receivers processes.The LLR of post processing turbine decoder, to regenerate frequency domain I/Q data and to perform rate-matched and transmission block interlocks.
Demodulation step (DM2) for the second time: in this third step, the I/Q data regenerated from regeneration step will be demodulated again.In second time demodulation step, it is possible to use identical Radio Resource (such as RB) offsets interference (if the I/Q data that they regenerate can be used) from other mobile subscribers.In the case of using CoMP, this can be MIMO user, it is also possible to be other CoMP mobile subscribers in local mobile subscriber or neighbor cell.After Interference Cancellation completes, the similar steps such as equilibrium, IDFT, demapping, release of an interleave, solution rate-matched and turbine decoding will be performed.
It should be noted that regeneration step and second time demodulation step perform the most all the time, because CRC may be correct after first time demodulation step.Sometimes, if there being other mobile subscribers to share same RB, the most only performing regeneration step, the data regenerated can be used to carry out Interference Cancellation.In the case, regeneration step is only performed.
Above three step is similar for all mobile subscribers in subframe.If there being four local mobile subscribers (such as UE or other mobile entities being suitable for) L1, L2, L3, L4, processing unit may one by one process mobile subscriber, performs whole three steps including for each mobile subscriber, as shown in Figure 2.
Process the second way of mobile subscriber as shown in Figure 3.In the case, processing procedure, from the beginning of performing all users to demodulate for the first time, then regenerates all mobile subscribers, finally performs second time demodulation.
Above two arranges processing sequence can be considered as two kinds of extreme situations, and to use any order can depend on the operational feasibility in software/hardware framework, the probability etc. of such as parallel processing.It is true that there is a variety of possible merging between both patterns.
According to the present invention, inventor recognizes that processing sequence should adapt to delay and the bandwidth requirement of up-link folding (such as CoMP).Therefore, processing sequence based on the classification of mobile subscriber in cellular radio Communication system, thus should realize the target of the present invention.
Therefore, the present invention relates to a kind of method that arrangement processes reception data in cellular radio Communication system.Communication system is used for merging into the uplink data that mobile subscriber (as in systems) receives in two or more communities.Additionally, system comprises first community as mobile subscriber's Serving cell, and one or more cooperation cell being associated with the first community.The uplink data received in Serving cell and cooperation cell can merge according to the method described above.The method includes the steps of:
Mobile subscriber is divided into dissimilar by the-mode of sharing Radio Resource according to mobile subscribers different in system.Radio Resource is that (such as) is respectively the first community and the spectrum of the second community distribution；And
-process, according to the above-mentioned classification of mobile subscriber, the uplink data being associated with each mobile subscriber in order.
In the diagram, we describe the example of mobile subscriber RB distribution for Serving cell and the cooperation cell that is associated.Serving cell can be considered as the community that mobile subscriber belongs to, and the data of mobile subscriber are decoded wherein, the more high-level being subsequently sent in communication system.On the other hand, cooperation cell can help Serving cell to perform process, but will not be decoded mobile user data.
In the case, Serving cell has four users, i.e. three local users (L1, L2, L3) and multi-cell cooperating (MC) mobile subscriber that can be considered as CoMP mobile subscriber.The RB of mobile subscriber distributes from a few RB to 100RB, and this depends on bandwidth requirement and channel condition.Cooperation cell has four local mobile subscribers (L1, L2, L3, L4), but also serves as belonging to the MC mobile subscriber of Serving cell simultaneously, has the RB of distribution.In this example, the RB distribution of MC mobile subscriber is placed on first piece of RB.
Owing to the two or more communities on same RB have received identical signal, therefore according to the present invention likely by optimal sequential processing user, so that the time that I/Q data is transferred to Serving cell from cooperation cell maximizes.In LTE, after antenna processing completes, each mobile subscriber can process independent of the every other mobile subscriber in system.This means that processing plan personnel can arrange processing sequence by any-mode, this is a kind of speciality that the method has.
In the example of hgure 5, first Serving cell can process local mobile subscriber L1, L2 and L3 before starting to process MC mobile subscriber, and the antenna data of MC mobile subscriber can be sent to Serving cell by cooperation cell at the beginning, then reprocess its local mobile subscriber L1, L2, L3, L4.By this arrangement, the time that data are transferred to Serving cell from cooperation cell is maximized.
In order to optimize total system ability, preferably utilize identical RB (that is, identical Radio Resource) for MC mobile subscriber and local mobile subscriber.When applying this resource-sharing, owing to two or more mobile subscribers use identical Radio Resource (such as wireless spectrum), it is therefore necessary to support MC mobile subscriber IC.Therefore, in order to a specific mobile subscriber decoding, it is necessary to correspondingly offset/deduct the signal of another mobile subscriber.
If we are with identical example citing, now in cooperation cell, the RB of local mobile subscriber L1 is overlapping with the RB of the MC mobile subscriber belonging to Serving cell.When two mobile subscribers share identical Radio Resource, the effective ways strengthening detection performance are Interference Cancellations, it means that the interference data from other users will be offset (the most also referred to as deducting) from its data.This is the technology detected for virtual MIMO (VMIMO, also referred to as multiuser MIMO) in Advanced receivers, but the most effective for using CoMP to carry out resource-sharing in up-link merges scene.This example shows in figure 6.
About Fig. 7, when applying CoMPIC, first data transfer is transferred to Serving cell from cooperation cell, is expressed as A in the figure 7.If mistake occurs in data decoding, then will perform second time decoding, and regenerate data in Liang Ge community.If the data decoding of local mobile subscriber L1 is correct in cooperation cell, then, before performing second time demodulation/decoding, its I/Q data regenerated will be sent to Serving cell and be used for offsetting.Data are transferred to Serving cell and are expressed as C in the figure 7 for the second time.Note that Serving cell and cooperation cell all can benefit from Interference Cancellation, this is because cooperation cell has arranged the local mobile subscriber agreeing on RB as MC mobile subscriber, be expressed as B in the figure 7.
If cooperation cell is after sending data for MC mobile subscriber, process first time and second time demodulation for local user L1, then Serving cell processes the time maximization that MC mobile subscriber lasts till that data shift, as shown in Figure 8.If CRC is correct, the I/Q data regenerated can be sent to Serving cell for local user L1 by cooperation cell, in order to carry out Interference Cancellation.
If the CRC of Serving cell is correct, then the transfer of second time data becomes irrelevant.But, regardless of whether use regeneration data, preferably transmit it out, in order to avoid causing due to the time of transfer time using regeneration data.
If the CRC of Serving cell is correct, but the CRC of local mobile subscriber is incorrect in cooperation cell, then cooperation cell will be benefited, as shown in the dotted arrow in Fig. 7 from the regeneration data offsetting MC mobile subscriber in second time demodulation step from the data of local mobile subscriber.
In the scene shown in Fig. 9, processing sequence needs to consider that regeneration data may be transmitted by two kinds of approach of B and C in Fig. 9.Having a kind of processing method is that the processing procedure of mobile subscriber L1 local in cooperation cell is divided into two parts, and processes other local mobile subscriber L2 and L3 between the two parts.Using same method, in Serving cell, the process of MC mobile subscriber is also classified into two parts, and wherein local mobile subscriber processes between the two parts.By this arrangement, it is possible to obtain the extra time transmitting data between Liang Ge community, but this time is less than example before.Figure 10 illustrates how to arrange scheduling in the relevant Serving cell of example and cooperation cell.
CoMP processes in RB rank, it means that CoMP scene is the same in certain RB, but likely differs from adjacent RB.Resource distribution between mobile subscriber may change, and does not has dependency between the mobile subscriber in neighbor cell.Therefore, use in one cell a large amount of Radio Resource mobile subscriber may mobile subscribers multiple with neighbor cell overlapping.Mobile subscriber in one community may only one of which or a few RB overlapping with other mobile subscribers in other communities.It can therefore be appreciated that if different combinations, quantity can be the biggest.
In the systematic method describing the present invention, the mobile subscriber in cellular communication system will be divided into dissimilar according to the mode sharing Radio Resource.According to this classification, determine processing sequence for the mobile subscriber in communication system.
In fig. 11, illustrate in A and B of Liang Ge community, share Radio Resource.In each cell, multiple mobile subscriber is had to each account for using a certain amount of RB.Index A value I is used for the compound boundary in labelling Liang Ge community A and B between mobile subscriber.As shown in figure 11, there are not two mobile subscribers of shared identical RB collection.In all examples the most such.
Owing to the multiple mobile subscribers in Liang Ge community are MC mobile subscribers, it is therefore necessary to shift data from respective community to perform for the first time and second time demodulation step, as shown in figure 12.It is also to be noted that, due to overlap, the data exchange of minizone is typically the sub-fraction of other community users RB, and is likely to be derived from two or more mobile subscribers.
Mobile subscriber can be divided into dissimilar (T) according to an embodiment of the present, according to principle, wherein has two parameters in classification.First parameter instruction mobile subscriber be the local mobile subscriber in Serving cell (i.e., belong to a community and not by the mobile subscriber of multiple community associated detections) or multi-cell cooperating (MC) mobile subscriber is (i.e., by the mobile subscriber of multi-cell joint detection, such as CoMP mobile subscriber), whether second parameter instruction mobile subscriber shares Radio Resource with the local mobile subscriber in cooperation cell or multi-cell cooperating mobile subscriber:
● type 0 (local/-): type 0 (T0) is to there is not community A or B up-link is closed and there is not the local mobile subscriber in the case of the data exchange of minizone.The user EU0 of Figure 11 small area A (between RB Index A and B) be type be the mobile subscriber of T0.This situation illustrates in figure 13a.
● Class1 (MC/ is local): Class1 (T1) is MC mobile subscriber, wherein its all or part RB is shared by the one or more local mobile subscriber in cooperation cell.User UE3A and UE3B in Figure 11 example broadly falls into this classification.This situation illustrates in Figure 13 C.
● type 2 (this locality/MC): type 2 (T2) is to share the local mobile subscriber of all or part of RB with the MC user in other communities.In the example of fig. 11, UE0B, UE2A, UE2B and UE4A broadly fall into this classification.
● type 3 (MC/MC): type 3 (T3) is and one or more MC mobile subscribers in cooperation cell and one or more mobile local users may share the MC mobile subscriber of Radio Resource with cooperation cell.In other words, type is that the mobile subscriber of T3 belongs simultaneously to cooperation cell and Serving cell.User UE1A and UE1B in Figure 11 example belongs to type T3 classification.Owing to topological structure pattern will be changed, therefore it is decoded the mobile subscriber that type is T3 needing to be divided into two parts.Illustrating by UE1A, for the RB between index B and C, topological structure pattern can be to show in Figure 13 C.RB between C and D, Figure 13 B are suitable for.
● type 4 (-/MC): type 4 (T4) is not share the MC mobile subscriber of its RB with any other mobile subscriber in system.This means cooperation cell is transmitted the most on the same RBs the local mobile subscriber of data for MC mobile subscriber.Mobile subscriber UE5A in Figure 11 be type be the example of the mobile subscriber of T4.This situation illustrates in Figure 13 D.
If the mobile subscriber of community A belongs to type T1, then the mobile subscriber in community B interactional with it belongs to type T2, and vice versa.If certain mobile subscriber belongs to type T3, then in other communities, mobile subscriber interactional with it falls within the mobile subscriber that type is T3, and this is due to according to the different types of definition of the present invention.Such as, type be mobile subscriber's Mirroring Mapping of T1 on the mobile subscriber that type is T2, type is that mobile subscriber's then Mirroring Mapping of T3 is first-class the mobile subscriber that other types are T3.
According to above-described embodiment, mobile subscriber has been divided into the different user types of T0 to T4.From such classification it can be seen that the A of community type be that the mobile subscriber of T1 can be paired with the mobile subscriber that type in the B of community is T2.Additionally, according to above-mentioned explanation, in the A of community, type is that the mobile subscriber of T3 is paired with the mobile subscriber that type in the B of community is T3.From these relations, comprehend at the data of user couple and separate as much as possible, in order to allow maximum time to be in harmonious proportion between second time demodulation in solution for the first time and transmit I/Q data.
Chronogram in Figure 14 shows principle and the processing sequence of different types of mobile subscriber of delivery time in cellular radio Communication system according to embodiments of the present invention, the data transfer time that wherein processing sequence is additionally based upon between Serving cell and cooperation cell.
Top half at Figure 14, it is shown that user between delivery time, and in the latter half of Figure 14, it is shown that the processing sequence of different types of mobile subscriber:
● the time T in Figure 140It is that antenna data (I/Q data) is sent to the time needed for other communities from a community.At T0Any CoMP process can not be performed before.At T0Before, the mobile subscriber that type is T0 and T2 can only be processed respectively, therefore should perform.In order to allow the maximum delivery time, should and then process, after processing the mobile subscriber that type is T0, the mobile subscriber that type is T2.
● time T1It is to demodulate, from the first time of the mobile subscriber that type is T2, the time terminating to start to the second time demodulation step of the mobile subscriber that type is T1.
● time T2From the beginning of at the end of the first time demodulation step of the mobile subscriber that type is T3, the second time to the mobile subscriber that type is T3 terminates when demodulating and start.
● time T3From the beginning of at the end of the first time of the mobile subscriber that type is T1 demodulates, the second time to the mobile subscriber that type is T2 terminates when demodulating and start.
Owing to MC mobile subscriber is individually selected by each community, the mobile subscriber arranged in the most each community must comply with system convention.Using above-mentioned classification, scheduling rule should be as follows according to embodiment:
1. type is the mobile subscriber-first time demodulation of T2；
2. type is that the mobile subscriber of T0 is (until time T0Before end)-demodulate with second time for the first time；
3. type is the mobile subscriber-first time demodulation of T3；
4. type is the mobile subscriber-first time demodulation of T1；
5. type is mobile subscriber-first time and the second time demodulation of T0；
6. type is mobile subscriber-first time and the second time demodulation of T4；
7. type is the mobile subscriber-second time demodulation of T1；
8. type is the mobile subscriber-second time demodulation of T3；
9. type is the mobile subscriber-second time demodulation of T2.
Processing in step at first and perform process, the execution time can be from the time 0 until receiving I/Q data (terminating when time T0) from other communities.In the above-described embodiments, first type of priority treatment is the mobile subscriber (demodulation DM1 for the first time) of T2, because they are paired with the mobile subscriber that type is T1, and regenerate data and needs early transmission.Have the time to process if surplus before T0, then type is that the mobile subscriber of T0 will process in step 2.
In step 3, perform the first time demodulation of the mobile subscriber that type is T3, and in step 4, perform the first time demodulation of the mobile subscriber that type is T1.In step 5 and 6, process type is the mobile subscriber of T0 (non-MC) and mobile subscriber that type is T4 (only MC).Afterwards in step 7-9, process the second time demodulation of the mobile subscriber that type is T1, T3 and T2.
It should be noted, may be the sub-fraction of whole RB total amount for the RB of MC mobile subscriber, most possible less than the 20% of total RB amount meansigma methods, it means that remaining 80%RB is local Radio Resource used by LTE mobile subscriber, process these users and be performed without data exchange in community.
Initial time T0It is provided with restriction to when any CoMP process can be started.Therefore, a kind of strategy is from the beginning of processing the mobile subscriber that type is T2, because the MC mobile subscriber that type paired in other communities is T1 depends on the data that type is T2, to carry out demodulating for the second time.It is also to be noted that processing type is the user of T3 and the mobile subscriber that type is T1 can exchange in principle.
Additionally, a good selection is after the first time of the mobile subscriber that type is T1 demodulates, and before the second time demodulation of the mobile subscriber that type is T1 starts, the mobile subscriber that type is T0 is processed, in order to by the delivery time from T1Expand to T3。
And it should be noted that, for mobile subscriber's (major part RB may be taken) that type is T0, can perform in order for the first time and second time demodulates rather than segment processing.
It has to be understood that, the I/Q data of different mobile subscribers is generally shared identical physics and is transmitted link.Delivery time T1、T2And T3It is overlapped mutually, and may be congested in multiple time slots, when determining processing sequence, this situation is likely to need to become parameter.
Type T1/T2 and T3/T3 do not represent complete mirror image in pairs.Type is that the mobile subscriber of T1 is likely the most overlapping with the mobile subscriber that type is T2, and vice versa.Type is that the mobile subscriber of T3 is to being also such.Certain MC mobile subscriber can be overlapping with the two or more MC mobile subscribers in other communities, and these mobile subscribers belong to type T3.
Type is that the mobile subscriber of T4 should be in the post processing of the mobile subscriber that type is T0, because the former can not be at time T0Start to process before.Type is that the mobile subscriber of T4 can perform for the first time and second time demodulation successively, i.e. the data transmission of minizone can only perform once.
Additionally, with regard to known to professional and technical personnel, can also implement according to the method for gained of the present invention, have code implication in computer program, when running on computers, this computer program can make each step of computer implemented method.This computer program is included in the computer-readable media of computer program.Computer-readable media substantially can be made up of any memorizeies such as ROM (read only memory), PROM (program read-only memory), EPROM (erasable and programmable readonly memor), flash memory, EEPROM (EEPROM) or hard disk drive.
