CSI反馈方法、装置、设备及可读存储介质
相关申请的交叉引用
本申请主张在2021年03月23日在中国提交的中国专利申请No.202110309794.X的优先权,其全部内容通过引用包含于此。
技术领域
本申请属于通信技术领域,具体涉及一种信道状态信息(Channel State Information,CSI)反馈方法、装置、设备及可读存储介质。
背景技术
对于多发送接收点/多天线面板(multi-Transmitting Receiving Point(multi-TRP,MTRP)/multi-panel)场景,可以增加传输的可靠性及吞吐量性能,例如终端可以接收来自于多个TRP的相同数据或不同数据。多TRP间可以分为理想回程线路(ideal backhaul)和非理想回程线路(non-ideal backhaul)。非理想回程线路时,多TRP间交互信息存在较大时延,比较适合独立调度,肯定确认(Acknowledgement,ACK)/否定确认(Negative Acknowledgement,NACK)和CSI报告分别向各TRP反馈。通常适用于多下行控制信息(Downlink Control Information,DCI)调度,即每个TRP发送各自的物理下行控制信道(Physical downlink control channel,PDCCH),每个PDCCH调度各自的物理下行共享信道(Physical downlink shared channel,PDSCH),为终端配置的多个控制资源集(Control resource set,CORESET)关联到不同的无线资源控制(Radio Resource Control,RRC)参数控制资源集池索引(CORESET PoolIndex),对应不同的TRP。多个DCI调度的多个PDSCH在时频资源上可能是不重叠、部分重叠、完全重叠的。在重叠的时频资源上,每个TRP根据各自的信道进行独立预编码,终端按照非相干联合传输(non-coherent joint transmission,NCJT)的方式接收属于多个PDSCH的多层数据流。
理想回程线路时,多TRP之间可以实时交互调度信息和UE的反馈信息, 除了可以通过上述的多DCI调度多PDSCH,还可以单DCI调度PDSCH,包括如下一些传输方案:
(1)空分复用(Space Division Multiplexing,SDM):同一传输块(Transport Block,TB)的不同数据层来自不同TRP的NCJT。
(2)频分复用(Frequency Division Multiplexing,FDM):同一TB同一冗余版本(Redundancy Version,RV)映射的不同频域资源发自不同TRP或同一TB的不同RV映射到不同频域资源并发自不同TRP。
(3)时分复用(Time division multiplexing,TDM):同一TB的不同RV的多次重复来自不同TRP,例如在一个时隙内的重复,或多个时隙的重复。
此时ACK/NACK反馈和CSI报告可以向任意一个TRP进行反馈。
然而,现有CSI报告的映射主要是针对一种测量假设设计,无法很好的支持多种测量假设。

在本申请的一种实施方式中,所述方法还包括:
在所述多个CSI报告中包括:多TPR(MTRP)的CSI报告时,所述终端确定所述多个CSI报告中CSI报告的传输优先级,所述多TPR的CSI报告中CSI内容的传输优先级中的一项或多项;

2)PMI和CQI颗粒度为subband时,part1优先级大于part2 wideband、part2内NCJT测量假设优先级优先级大于part2内STRP测量假设优先级;Part2内wideband域优先级大于part2 subband域。
比如,当一次CSI反馈基于物理上行控制信道(Physical Uplink Control Channel,PUCCH)或者物理上行共享信道(Physical Uplink Shared Channel,PUSCH)时,如果反馈的多个CSI报告中存在MTRP的CSI报告时,则需要确定多个CSI报告之间的优先级,以及MTRP的CSI报告包含内容的优先级。
在本申请的一种实施方式中,所述多个CSI报告中各个CSI报告的传输优先级,包括以下一项或者多项:
(1)对于基于PUSCH报告的多个非周期CSI报告,且均为非承载层1参考信号接收功率(Layer 1 Reference Signal Received Power,L1-RSRP)或者层1信号与干扰加噪声比(Layer 1 Signal to Interference plus Noise Ratio, L1-SINR),MTRP的CSI报告优先级高于非MTRP的CSI报告;
(2)基于PUSCH报告的多个半持续CSI报告,且均为非承载L1-RSRP或者L1-SINR,MTRP的CSI报告优先级高于非MTRP的CSI报告;
(3)基于PUCCH报告的多个半持续CSI报告,且均为非承载L1-RSRP或者L1-SINR,MTRP的CSI报告优先级高于非MTRP的CSI报告;

例如:MTRP的CSI报告优先级高于非MTRP的CSI报告对应计算公式可能为:Pri iCSI(y,k,m,c,s)=2·N celle·M s·y+N cells·M s·k+N cells·M s·m/2+Ms·c+s,其中m=0表示该报告承载的是MTRP的CSI报告,m=1表示该报告承载的是STRP CSI报告。
