为便于更好的理解本申请实施例,对本申请相关的基于码本的物理上行共享信道(physical uplink shared channel,PUSCH)的传输方案进行说明。
具体的,如图2所示,基于码本传输方案的流程可以包括以下步骤:
1、终端设备向网络设备发送基于码本(codebook)的PUSCH传输对应的探测参考信号(sounding reference signal,SRS);
2、网络设备根据终端设备发送的SRS进行上行信道检测,对终端设备进行资源调度,并确定出PUSCH传输对应的SRS资源、SRS资源指示(SRS resource indicator,SRI)、发送预编码矩阵指示(Transmit Precoding Matrix Indicator,TPMI)、上行传输的层数、调制编码方案(Modulation and Coding Scheme,MCS);以及网络设备通过下行控制信息(downlink control information,DCI)向终端设备指示上述信息;
3、终端设备接收DCI,并按照DCI的指示发送PUSCH。
为便于更好的理解本申请实施例,对本申请相关的基于非码本的PUSCH的传输方案进行说明。
具体的,如图3所示,基于非码本传输方案的流程可以包括以下步骤:
1、终端设备测量下行参考信号,获得候选的预编码矩阵,利用候选的预编码矩阵对SRS进行预编码之后,向网络设备发送基于非码本(non-codebook)的PUSCH传输对应的SRS;
2、网络设备根据终端设备发送的SRS进行上行信道检测,对终端设备进行资源调度,并确定出PUSCH传输的波束(beam)对应的SRS资源;网络设备通过DCI向终端设备指示上述信息;
3、终端设备接收DCI,并按照DCI的指示发送PUSCH。
为便于更好的理解本申请实施例,对本申请相关的基于码本的PUSCH传输的控制信令进行说明。
在基于码本的PUSCH传输方案中,网络设备通过DCI格式向终端设备指示PUSCH对应的SRS资源,上行传输的层数,预编码矩阵。DCI中的字段为预编码信息和层数(Precoding information and number of layers)和SRI。
DCI中的TPMI比特数的影响因素包括:天线端口数、根据高层参数码本子集(codebookSubset)配置的状态确定的码本子集,最大传输层数。其中,codebookSubset配置的状态要根据终端设备上报的能力来配置,终端设备上报的内容包括:终端设备的所有天线是相干传输的,终端设备的天线是部分相干传输的,终端设备的天线是非相干传输的。
对应上述内容,TPMI中的每一个状态指示了上行信息传输使用的预编码矩阵。
为便于更好的理解本申请实施例,对本申请所解决的问题进行说明。
1、上行传输最多可以支持天线端口数为4的上行传输;
2、终端设备可以上报能力支持部分相干传输,且能够进行部分相干传输的天线端口是4端口中的2个端口。
对于更多的天线端口数(如天线端口数为6或天线端口数为8)的上行传输,尚未涉及码本设计。
基于上述问题,本申请提出了一种多端口传输的码本设计方案,设计了支持天线端口数量大于4的码本,从而提升了上行传输的性能。

在本申请实施例中,终端设备支持部分相干传输的码本子集,则终端设备也支持非相干传输的码本子集。
