技术领域technical field
本发明涉及LTE(Long Term Evolution，长期演进)，尤其涉及一种上行接收方法及装置。The present invention relates to LTE (Long Term Evolution, long term evolution), in particular to an uplink receiving method and device.
背景技术Background technique
LTE系统中，上行的物理信道/信号有SRS(Sounding Reference Signal，探测参考信号)、PUSCH(Physical Uplink Shared Channel，物理上行共享信道)、PUCCH(PhysicalUplink Control channel，上行控制信道)等。In the LTE system, uplink physical channels/signals include SRS (Sounding Reference Signal, sounding reference signal), PUSCH (Physical Uplink Shared Channel, physical uplink shared channel), PUCCH (Physical Uplink Control channel, uplink control channel) and so on.
PUCCH信道负责上行的控制信息的周期上报，控制信息包括HARQ-ACK(HybridAutomatic Repeat request-Acknowledgement，混合自动重传请求-确认)、SR(SchedulingRequest，调度请求)、CQI(Channel Quality Indication，信道质量指示)、PMI(PrecodingMatrix Index，预编码矩阵指示)、RI(Rank Indication，秩指示)等。The PUCCH channel is responsible for the periodic reporting of uplink control information. The control information includes HARQ-ACK (HybridAutomatic Repeat request-Acknowledgment, hybrid automatic repeat request-acknowledgement), SR (SchedulingRequest, scheduling request), CQI (Channel Quality Indication, channel quality indication ), PMI (PrecodingMatrix Index, precoding matrix indication), RI (Rank Indication, rank indication), etc.
PUSCH负责承载业务信息，同时也承载控制信息。The PUSCH is responsible for carrying service information and also carrying control information.
SRS信号是为了进行上行资源的动态配置，用于对频域瞬时信道质量进行估计。The SRS signal is used for dynamic allocation of uplink resources, and is used for estimating instantaneous channel quality in the frequency domain.
定义信道和信号的同时，协议也规定了相关约束，比如PUSCH与PUCCH不可能同时存在，如果需要传输控制信息，且TTI(Transmission Time Interval，传输时间间隔)内该UE(User Equipment，用户设备)没有PUSCH，那么控制信息由PUCCH进行传输，否则在PUSCH上进行传输；PUCCH、PUSCH处理时，如果存在SRS，要把SRS的资源预留出来，在这些约束条件下，目前还没有较好方法实现上行接收效率最高。While defining channels and signals, the protocol also stipulates related constraints. For example, PUSCH and PUCCH cannot exist at the same time. If control information needs to be transmitted, and the UE (User Equipment, user equipment) within TTI (Transmission Time Interval, transmission time interval) If there is no PUSCH, the control information is transmitted by PUCCH, otherwise it is transmitted on PUSCH; when PUCCH and PUSCH are processed, if there is SRS, the resources of SRS should be reserved. Under these constraints, there is no better way to realize it. Uplink receiving efficiency is the highest.

具体实施方式Detailed ways
本实施方式从整个LTE物理层上行接收入手，设计了一种高效的并行接收系统，能有效的解决多信道配置时产生的冲突，实现冲突的仲裁和分离机制，在具体每条信道的处理过程中，可以不用关心与之冲突的信道，这种方式提高了各个信道处理的效率，也便于各个信道实现分离，以及子系统并行处理的实现。同时，对于上行较为复杂的PUCCH的处理，由于其内部也存在多种控制信息的冲突和复用问题，本实施方式的优化方案减少了其内部监测的迂回，能够提高PUCCH的检测效率及处理能力。This embodiment starts from the uplink reception of the entire LTE physical layer, and designs an efficient parallel reception system, which can effectively resolve the conflicts generated during multi-channel configuration, and realize the conflict arbitration and separation mechanism. In the specific processing process of each channel In , you don't need to care about the channels that conflict with it. This method improves the efficiency of each channel processing, and also facilitates the separation of each channel and the realization of parallel processing of subsystems. At the same time, for the processing of the more complicated PUCCH in the uplink, since there are conflicts and multiplexing problems of various control information inside it, the optimization scheme of this embodiment reduces the detour of its internal monitoring, and can improve the detection efficiency and processing capacity of PUCCH .
另外，本实施方式对信道冲突除了解决了SRS处理过程使用PUSCH或PUCCH相关信息的问题，将关联问题推至多信道综合判断环节，从现实意义上提高了SRS的处理效率，降低了多个信道处理子系统的耦合，实现了并行处理，克服了串行处理及迂回判断所带来的效率低下等问题。再则，PUCCH内部处理的多资源检测对象确定中基于门限的优化解决办法提高了检测效率，具备一定程度的自适应性。In addition, this embodiment not only solves the problem of using PUSCH or PUCCH related information in the SRS processing process for channel conflicts, but pushes the correlation problem to the multi-channel comprehensive judgment link, which improves the processing efficiency of SRS in a practical sense and reduces the number of multiple channel processing. The coupling of subsystems realizes parallel processing and overcomes the problems of inefficiency caused by serial processing and circuitous judgment. Furthermore, the optimization solution based on the threshold in the multi-resource detection object determination of the internal processing of the PUCCH improves the detection efficiency and has a certain degree of adaptability.

步骤207：判断是否接收到UE的PUSCH解调参数，如果接收到，则执行步骤208；否则，执行步骤209；Step 207: Judging whether the PUSCH demodulation parameters of the UE have been received, and if so, execute step 208; otherwise, execute step 209;
步骤208：将除去SR之外的UCI的解调参数传入PUSCH处理子系统；Step 208: Pass the demodulation parameters of UCI except SR to the PUSCH processing subsystem;
步骤209：将包含SR的UCI的解调参数传入PUSCH处理子系统。Step 209: Send the demodulation parameters of the UCI including the SR to the PUSCH processing subsystem.
步骤103：在确定可能同时存在SRS与PUSCH时，进行SRS与PCSCH是否冲突的初步检测，在确定可能同时存在SRS与PUCCH时，进行SRS与PUCCH是否冲突的初步检测；Step 103: When it is determined that SRS and PUSCH may exist at the same time, perform a preliminary detection of whether SRS and PCSCH collide, and when it is determined that SRS and PUCCH may exist at the same time, perform a preliminary detection of whether SRS and PUCCH collide;
如图3所示，进行SRS与PUSCH或进行SRS与PUCCH冲突的初步检测，包括：As shown in Figure 3, the preliminary detection of SRS and PUSCH or SRS and PUCCH conflicts includes:
步骤301：判断UE是否处于SRS的周期中，如果是，则执行步骤302；否则，确定未发生冲突；Step 301: Determine whether the UE is in the period of the SRS, if yes, execute step 302; otherwise, determine that no conflict occurs;
可以根据UE的参数得知UE是否处于SRS的周期中。Whether the UE is in the period of the SRS can be known according to the parameters of the UE.
步骤302：判断UCI中是否包含SR的检测信息，如果未包含，则执行步骤303；否则，确定未发生冲突；Step 302: Determine whether the UCI contains SR detection information, if not, execute step 303; otherwise, determine that no conflict occurs;

步骤304：丢弃SRS的处理信息，认为UE未发送SRS。Step 304: The processing information of the SRS is discarded, and it is considered that the UE has not sent the SRS.
在UE不存在SR(判断SR的原因是CQI与正的SR冲突时，将会丢弃CQI)，但存在CQI(ACK/NACK是否存在并不考虑)时，会出现SRS与PUCCHFormat2/2a/2b或PUSCH的冲突，UE会丢弃SRS，相应的基站上行接收系统也就不需要对UE的SRS进行测量等处理，否则进行SRS的处理。When there is no SR in the UE (the reason for judging the SR is that the CQI collides with the positive SR, the CQI will be discarded), but there is a CQI (the existence of ACK/NACK is not considered), SRS and PUCCHFormat2/2a/2b or In case of PUSCH conflict, the UE will discard the SRS, and the corresponding uplink receiving system of the base station does not need to measure the SRS of the UE, otherwise, the SRS will be processed.
步骤104：当上行接收机接收到空口数据后，分别启动各信道处理子系统和信号处理子系统，使处于就绪状态，包含PUCCH处理子系统、PUSCH处理子系统和SRS处理子系统，根据冲突的检测结果将信道任务和/或信号任务发送给相应的信道处理子系统和/或信号处理子系统进行处理；Step 104: After the uplink receiver receives the air interface data, start each channel processing subsystem and signal processing subsystem respectively, so that they are in the ready state, including the PUCCH processing subsystem, PUSCH processing subsystem and SRS processing subsystem, according to the conflicting The detection result sends the channel task and/or signal task to the corresponding channel processing subsystem and/or signal processing subsystem for processing;
各信道处理子系统和信号处理子系统为并行子系统，并不需要相互之间交互信息。The channel processing subsystems and signal processing subsystems are parallel subsystems and do not need to exchange information with each other.
多个子系统可由多个CPU或Core或IP来完成。Multiple subsystems can be completed by multiple CPUs or Cores or IPs.
同一UE可能同时存在SRS和PUSCH，或同时存在SRS和PUCCH，即，对于一个UE可能同时将SRS和PUSCH，或将SRS和PUCCH送入两个子系统进行处理，在存在冲突时，经过冲突初步检测后对于一个UE更多情况下是在一个时刻仅对SRS、PUSCH和PUCCH的其中一个进行处理。。The same UE may have SRS and PUSCH at the same time, or SRS and PUCCH at the same time, that is, a UE may send SRS and PUSCH, or SRS and PUCCH to two subsystems for processing at the same time. In most cases, only one of SRS, PUSCH and PUCCH is processed at a time for a UE. .
步骤105：各个子系统处理结束后，综合判决子系统对解调结果进行综合判断，确定需要上报的解调结果，并向高层上报解调结果。Step 105: After processing by each subsystem, the comprehensive judgment subsystem makes a comprehensive judgment on the demodulation results, determines the demodulation results that need to be reported, and reports the demodulation results to the high-level.
如图4所示，对解调结果进行综合判决，确定需要上报的解调结果，包括：As shown in Figure 4, a comprehensive judgment is made on the demodulation results to determine the demodulation results that need to be reported, including:
步骤401：判断UE是否存在PUSCH，如果存在，则执行步骤402；否则，执行步骤405；Step 401: Determine whether the UE has a PUSCH, and if so, execute step 402; otherwise, execute step 405;
步骤402：判断UE是否存在SRS，如果存在，则执行步骤403；否则，执行步骤404；Step 402: Determine whether the UE has an SRS, and if so, execute step 403; otherwise, execute step 404;
步骤403：确定上报PUSCH和SRS的解调结果，并进行上报；Step 403: Determine and report the demodulation results of PUSCH and SRS, and report them;
步骤404：确定上报PUSCH的解调结果，并进行上报；Step 404: Determine and report the demodulation result of PUSCH, and report it;
步骤405：判断UE是否存在SRS，如果存在，则执行步骤406；否则，执行步骤409；Step 405: Determine whether the UE has an SRS, and if so, execute step 406; otherwise, execute step 409;
步骤406：判断UE是否存在PUCCH，如果存在，则执行步骤407；否则，执行步骤408；Step 406: Judging whether there is a PUCCH in the UE, if yes, execute step 407; otherwise, execute step 408;
步骤407：确定上报PUCCH和SRS的解调结果，并进行上报；Step 407: Determine and report the demodulation results of PUCCH and SRS, and report them;

步骤410：确定上报PUCCH的解调结果，并进行上报。Step 410: Determine to report the demodulation result of the PUCCH, and report it.
PUCCH不仅与PUSCH和SRS需要进行冲突和复用的检测，PUCCH所包含的多种控制信息也存在冲突和复用，同样也需要进行冲突的检测和复用处理，具体处理实现如下描述。PUCCH not only needs to perform collision and multiplexing detection with PUSCH and SRS, but also conflicts and multiplexing of various control information contained in PUCCH, and also needs to perform collision detection and multiplexing processing. The specific processing implementation is described as follows.
如图5所示，对PUCCH上的多个ACK资源的ACK/NACK解调，包括：As shown in Figure 5, the ACK/NACK demodulation of multiple ACK resources on the PUCCH includes:
步骤501：对PUCCH内部存在的M(M≥1)个潜在的ACK/NACK资源上的信噪比(SNR)或信号功率进行测量，得到信噪比或信号功率的测量值；Step 501: Measure the signal-to-noise ratio (SNR) or signal power on the M (M≥1) potential ACK/NACK resources existing in the PUCCH to obtain the measured value of the signal-to-noise ratio or signal power;
步骤502：将得到的测量值与门限PCfg进行比较，判断是否存在测量值大于门限PCfg的资源，如果不存在，则执行步骤503；如果存在，则执行步骤504；Step 502: Comparing the obtained measured value with the threshold PCfg , and judging whether there is a resource whose measured value is greater than the threshold PCfg , if not, execute step 503; if yes, execute step 504;
PUCCH内部存在M个潜在的ACK/NACK资源的情况下，M最大为4(TDD复用)，此时，先对各个ACK/NACK资源上的SNR进行测量，测量值为PSNR，并将信噪比的测量值与门限PCfg比较。为简单起见，并基于信号的底噪差异不大的事实，对SNR的测量可以弱化为对信号功率的测量，信号功率的测量值为PSignal，将信号功率的测量值PSignal与门限PCfg比较。When there are M potential ACK/NACK resources in the PUCCH, M is at most 4 (TDD multiplexing). At this time, the SNR on each ACK/NACK resource is measured first, and the measured value is PSNR , and the signal The measured value of the noise ratio is compared to a threshold PCfg . For the sake of simplicity, and based on the fact that the noise floor of the signal has little difference, the measurement of SNR can be reduced to the measurement of signal power, the measurement value of signal power is PSignal , and the measurement value of signal power PSignal and the threshold PCfg Compare.
步骤503：如果PSignal，k＜PCfg，(k＝0，1...M-1)，即不存在测量值大于门限PCfg的资源，则ACK/NACK资源上的检测结果判决为DTX(Discontinuous Transmission，不连续传输)，即UE未发送ACK/NACK；Step 503: If PSignal, k < PCfg , (k=0, 1...M-1), that is, there is no resource whose measurement value is greater than the threshold PCfg , then the detection result on the ACK/NACK resource is determined to be DTX (Discontinuous Transmission, discontinuous transmission), that is, the UE does not send ACK/NACK;
步骤504：选择测量值最大的资源，对选择的测量值最大的资源进行ACK/NACK解调；Step 504: Select the resource with the largest measurement value, and perform ACK/NACK demodulation on the selected resource with the largest measurement value;
如果Sum(Countif(PSignal，k＞PCfg))＝1，(k＝0，1...M-1)，Countif内的条件为真时，Countif的取值为1，否则为0，即测量结果中只有一个高于门限，则选择为测量值高于门限PCfg的资源进行ACK/NACK解调；If Sum(Countif(PSignal, k >PCfg ))=1, (k=0, 1...M-1), when the condition in Countif is true, the value of Countif is 1, otherwise it is 0, That is, only one of the measurement results is higher than the threshold, and the resource whose measurement value is higher than the threshold PCfg is selected for ACK/NACK demodulation;
如果Sum(Countif(PSignal，k＞PCfg))＞1，即存在多个测量结果高于门限的资源，那么对测量值最高的资源进行ACK/NACK的解调。If Sum(Countif(PSignal, k >PCfg ))>1, that is, there are multiple resources whose measurement results are higher than the threshold, then ACK/NACK demodulation is performed on the resource with the highest measurement value.
步骤505：对PUCCH的其他资源进行解调处理。Step 505: Demodulate other resources of the PUCCH.
本实施方式中对ACK/NACK资源进行的检测及解调处理，可以使物理层不再要求上层下发ACK确切的解调资源，提高了信道解调的效率。The detection and demodulation processing of the ACK/NACK resource in this embodiment can make the physical layer no longer require the upper layer to deliver the exact demodulation resource of the ACK, and improve the efficiency of channel demodulation.
可以对ACK/NACK检测门限的方法进行实现的优化，采用基于均值和方差的方法取代实际的门限方法，即信号中如果出现方差大于均值一定比例的情况(这个比例通常较容易选取)，即可将最大方差对应的资源选定为解调对象，如果未出现，则认为没有达到门限的资源，ACK/NACK的解调结果可认为是DTX。The ACK/NACK detection threshold method can be optimized, and the actual threshold method is replaced by a method based on the mean and variance, that is, if the variance in the signal is greater than a certain percentage of the mean (this ratio is usually easier to choose), then The resource corresponding to the maximum variance is selected as the demodulation object. If it does not appear, it is considered that there is no resource reaching the threshold, and the demodulation result of ACK/NACK can be considered as DTX.
如图6所示，对于PUCCH内部存在的CQI与Positive SR(正的调度请求)冲突的情况的检测，包括：As shown in Figure 6, the detection of the conflict between the CQI and the Positive SR (positive scheduling request) existing in the PUCCH includes:
步骤601：判断UCI是否包含SR的检测信息，如果包含，则执行步骤602；否则，执行步骤605；Step 601: Determine whether the UCI contains SR detection information, and if it does, execute step 602; otherwise, execute step 605;
步骤602：检测SR是否发送，即检测SR为Negative(负)SR还是PositiveSR；Step 602: Detect whether the SR is sent, that is, detect whether the SR is a Negative (negative) SR or a Positive SR;
步骤603：判断SR是否为Positive SR，如果是，则执行步骤604；否则，执行步骤605；Step 603: Determine whether the SR is a Positive SR, if yes, execute step 604; otherwise, execute step 605;
步骤604：确定UE会丢弃CQI，则基站也放弃CQI的解调，并记录检测到SR的标识；Step 604: After determining that the UE will discard the CQI, the base station also discards the demodulation of the CQI, and records the detected SR identifier;
步骤605：如果SR是Negative SR，则启动CQI的解调模块在CQI的资源上进行处理。Step 605: If the SR is a Negative SR, start the CQI demodulation module to process on the CQI resource.
如图7所示，对于PUCCH内部存在的SR与ACK冲突的情况的检测，包括：As shown in Figure 7, the detection of the conflict between SR and ACK in the PUCCH includes:
步骤701：判断UCI是否包含SR的检测信息，如果包含，则执行步骤702；否则，执行步骤705；Step 701: Determine whether the UCI contains SR detection information, and if it does, execute step 702; otherwise, execute step 705;
步骤702：在SR的资源上检测ACK/NACK；Step 702: Detect ACK/NACK on the resource of SR;
步骤703：判断检测结果是否为DTX，如果不是，则执行步骤704；否则，执行步骤705；Step 703: Determine whether the detection result is DTX, if not, execute step 704; otherwise, execute step 705;
步骤704：记录检测到SR的标识及ACK/NACK的结果；Step 704: record the detected SR identification and ACK/NACK results;
步骤705：在ACK/NACK的资源上重新解调ACK/NACK。Step 705: Re-demodulate the ACK/NACK on the resource of the ACK/NACK.
对于PUCCH内部存在ACK/NACK与Positive SR冲突的情况，可先在SR的资源上进行ACK/NACK的解调，然后再根据检测结果确定是否需要进一步在ACK/NACK资源上重新进行ACK/NACK解调。如果SR资源上检测到的ACK/NACK结果为DTX，即信号功率未达到检测门限，那么认为SR为Negative，在ACK/NACK的资源上重新解调ACK/NACK信道。For the conflict between ACK/NACK and Positive SR in PUCCH, ACK/NACK demodulation can be performed on SR resources first, and then determine whether further ACK/NACK demodulation needs to be performed on ACK/NACK resources according to the detection result Tune. If the ACK/NACK detected on the SR resource is DTX, that is, the signal power does not reach the detection threshold, then the SR is considered Negative, and the ACK/NACK channel is re-demodulated on the ACK/NACK resource.
如图8所示，对于PUCCH内部存在的ACK/NACK与CQI的冲突的情况(主要是指高层配置UE为ACK/NACK与CQI不能共传的情况)的检测，包括：As shown in Figure 8, the detection of the conflict between ACK/NACK and CQI in the PUCCH (mainly refers to the situation where the high layer configures the UE that ACK/NACK and CQI cannot be co-transmitted) includes:
步骤801：判断高层是否配置CQI与ACK/NACK可共传，如果配置可共传，则执行步骤802；如果配置不可共传，则执行步骤803；Step 801: Determine whether the upper layer configures CQI and ACK/NACK to be co-transmitted, if the configuration is co-transmission, then perform step 802; if the configuration is not co-transmission, then perform step 803;
步骤802：在CQI资源上检测CQI及ACK/NACK；Step 802: Detect CQI and ACK/NACK on CQI resources;
步骤803：在ACK/NACK的资源上检测ACK/NACK；Step 803: Detect ACK/NACK on the resource of ACK/NACK;
步骤804：判断检测结果是否为DTX，如果不是，则执行步骤805；否则，执行步骤806；Step 804: Determine whether the detection result is DTX, if not, execute step 805; otherwise, execute step 806;
步骤805：记录ACK/NACK的结果；Step 805: record the result of ACK/NACK;
步骤806：在CQI的资源上检测CQI。Step 806: Detect the CQI on the resource of the CQI.
ACK/NACK与CQI的冲突的情况可先单独在ACK/NACK资源上进行检测，如为DTX，则再对CQI资源进行检测，否则放弃CQI信道的解调。对于高层配置可以同时传输的情况，直接在CQI资源上进行CQI及ACK/NACK的解调。The conflict between ACK/NACK and CQI can be detected on the ACK/NACK resource alone first, if it is DTX, then the CQI resource is detected, otherwise the demodulation of the CQI channel is abandoned. For the case where high-level configurations can be transmitted simultaneously, CQI and ACK/NACK demodulation is directly performed on the CQI resource.
