本申请属于无线通信技术领域，具体涉及一种下行控制信息指示方法、上行信道传输秩确定方法及装置。
背景技术
为了提高上行数据传输的可靠性，Rel-17引入了多发送和接收点(Transmit Receive Point，TRP)的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)传输方法，即一个PUSCH的不同重复可以采用不同的波束发向多个TRP，来对抗链路阻塞波束遮挡带来的影响。
目前在多TRP场景中，确定了为终端配置两个信道探测用参考信号(Sounding Reference Signal，SRS)资源集，分别对应两个TRP。调度PUSCH的下行控制信息(Downlink Control Information，DCI)中包含两个SRS资源指示(SRS resource indicator，SRI)域和两个宽带预编码矩阵指示(Transmitted Precoding Matrix Indicator，TPMI)域，分别用来指示两套参数，同时用于PUSCH传输。其中两个SRI域对应指示两个SRS资源集中的SRS资源，每个SRS资源对应一个波束，这样PUSCH能同时采用两个波束发送，提高数据传输的可靠性。然而，如何对上述多TRP场景下用于调度PUSCH的DCI进行解读，还没有明确的定论。
另外，为了保证接收端能对PUSCH的不同重复传输进行合并来提高数据传输的可靠性，要求发向多个TRP的重复都对应相同的传输秩数(或称为传输层数)。此外，还引入了新的域来动态指示单TRP传输和多TRP传输的切换。目前，最大传输秩信息由无线资源控制(Radio Resource Control，RRC)信令配置，且一旦配置，则发往两个TRP的PUSCH的最大传输秩均受该配 置限制。当两个TRP能力不同，例如一个TRP支持终端传输4层数据，而另一个TRP仅支持传输2层数据时，网络侧会选择配置最大传输秩数是2层，这样即使下行控制信息(Downlink Control Information，DCI)指示切换到单TRP传输，如切换到支持4层数据传输的TRP，此时也无法实现最大传输秩大于2层的调度。因此现有技术限制了单TRP传输时的吞吐量性能。

下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的下行控制信息指示方法、上行信道传输秩确定方法及装置进行详细地说明。
下面首先对与本申请相关的通信术语进行说明。
1、基于码本的PUSCH传输模式：
网络侧为用户设备(User Equipment，UE，也称为终端)配置用于码本传输的SRS资源集，每个资源集包含至少一个SRS资源。UE根据配置的至少一个SRS资源发送SRS，网络侧通过接收SRS来获得上行信道，并基于此来确定UE上行数据承载信道PUSCH传输的波束、预编码矩阵和调制和编码方案(Modulation and coding scheme，MCS)等，并通过下行控制信息(Downlink Control Information，DCI)来通知UE。
UE接收调度PUSCH的DCI，DCI中的TPMI域从一个预定义的码本中选择一个用于所调度PUSCH传输的预编码矩阵，指示示例如表1。UE会根据所指示的TPMI对上行数据进行预编码后映射到PUSCH资源上进行传输。
表1预编码信息和层数，对于4个天线端口，如果禁用变换预编码器，则最大秩(maxRank)＝2或3或4

2、基于非码本的PUSCH传输模式：
网络侧为UE配置用于非码本传输的SRS资源集，每个资源集包含至少一个SRS资源。首先UE在网络侧配置的非零功率信道状态信息参考信号(Non-Zero Power Channel State Information Reference Signal，NZP CSI-RS)资源上检测网络侧发送的NZP CSI-RS，来获得下行信道状态信息。根据信道互易性，该下行信道信息可以近似等效为上行信道信息。UE根据上行信道信息来计算候选的用于上行传输的预编码矩阵对SRS进行预编码并发送，网络侧根据测量预编码后的SRS来进一步确定PUSCH传输所使用的预编码矩阵，并通过调度PUSCH的DCI来通知UE。
DCI的SRI域从一个预定义SRI索引表中选择一个SRS资源索引的一个子集即SRI组，来通知UE PUSCH的预编码采用的预编码矩阵，指示示例如表2。
表2基于非码本的PUSCH传输的SRI指示，L max＝4
Figure PCTCN2022109020-appb-000003
3、多TRP PUSCH传输的参数指示
目前在多TRP场景中，确定了为终端配置两个SRS资源集，分别对应两个TRP。调度PUSCH的DCI中包含两个SRI域和两个TPMI域，分别用来指示两套参数，同时用于PUSCH传输。其中两个SRI域对应指示两个SRS资源集中的SRS资源，每个SRS资源对应一个波束，这样PUSCH能同时采用两个波束发送，提高数据传输的可靠性。
同时为了提高多TRP传输的灵活性，DCI中引入了一个指示域，用于指示当前两个TRP哪一个还是哪两个TRP作为PUSCH传输的目标TRP。具体的指示参见图2：
(1)当指示域取“00”：只使用SRI域1和TPMI域1，且SRI域1对应SRS资源集1，即两个重复(重复1和重复2)都发送给TRP1。
(2)当指示域取“01”：只使用SRI域1和TPMI域1，且SRI域1对应SRS资源集2，即两个重复(重复1和重复2)都发送给TRP2。
(3)当指示域取“10”：SRI域1和TPMI域1对应SRS资源集1，SRI域2和TPMI域2对应SRS资源集2，即重复1发送给TRP1，重复2发送给 TRP2。
从上述内容可以看出，TRP1作为PUSCH传输的目标TRP时，使用SRI域1和TPMI域1指示与TRP1关联的PUSCH的信息，TRP2作为PUSCH传输的目标TRP时，也使用SRI域1和TPMI域1指示与TRP2关联的PUSCH的信息，使用SRI域1和TPMI域1指示与TRP2关联的PUSCH的信息时，终端如何读取SRI域1和TPMI域1是亟待解决的问题。
