Description

一种预编码指示方法、装置及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种预编码指示方法、装置及存储介质。
背景技术
随着通信技术的发展，为了保证覆盖范围，当网络设备(例如基站)有多个发送接收点(Transmission Reception Point，TRP)时，可以使用多个TRP(Multi-TRP)/多面板(panel)为终端提供服务。并且，为了在服务区内提供更为均衡的服务质量，引入多点协作传输(Coordinated Multiple Point transmission，CoMP)技术。
相关技术中，支持终端多panel基于码本的上行同时传输(STxMP)。其中，基于码本的上行同时传输中，终端需要配置最多一个探测参考信号(Sounding Reference Signal，SRS)资源集用于基于码本的上行传输。其中，SRS资源集可配置多个SRS资源，网络设备会根据SRS资源集合中SRS资源数量(N SRS)反馈
Figure PCTCN2022111524-appb-000001
比特的SRS资源指示(Sounding Reference Signal resource indicator，SRI)，以通过SRI指示选择SRS资源。并且，由网络设备决定终端实际传输使用的预编码矩阵(Transmission Precoding matrix indicator，TPMI)和传输层数(Rank Indicator，RI)并通知终端。终端在接下来的上行传输中的数据需要使用网络设备指定的TPMI和RI进行预编码，同时对于预编码后的数据按照SRI指示的SRS资源对应的空间滤波(Spatial Relation Info)映射到相应的天线端口上。
在相关通信协议研究中，对物理下行控制信道(physical downlink control channel，PDCCH)以及物理上行控制信道(physical uplink control channel，PUCCH)和物理上行共享信道(physical uplink shared channel，PUSCH)进行增强。
基于Multi-TRP的PUSCH增强，可以基于单个PDCCH，比如单个下行控制信令(single downlink control information，S-DCI)调度panel/TRP/TCI传输。其中，为了支持终端多panel基于码本的上行同时传输，需要在保证终端实现灵活性的基础上，考虑S-DCI调度下的不同传输方案对应的预编码指示增强方案。

在相关通信协议研究中，对物理下行控制信道(physical downlink control channel，PDCCH)以及物理上行控制信道(physical uplink control channel，PUCCH)和物理上行共享信道(physical uplink shared channel，PUSCH)进行增强。
基于Multi-TRP的PUSCH增强，可以基于单个PDCCH，比如单个下行控制信令(single downlink control information，S-DCI)调度多panel/TRP/TCI传输。其中图2示出了一种S-DCI调度下的MP-MTRP传输场景示意图。参阅图2所示，终端UE在panel1上向TRP1发送TPMI1，在panel2上向TRP2发送TPMI2。
在相关技术中的基于非码本和码本的M-TRP传输中，DCI中的SRI域指示SRS资源集中的SRS资源，由于R17支持两个SRS资源集，因此在基于非码本的M-TRP PUSCH重复传输中，DCI格式0_1/0_2中包含与两个SRS资源集关联的两个SRI域，每个SRI域为一个TRP指示SRI，第一个SRI域的设计基于R15/16的框架，且所有重复传输均采用相同的层数。
其中对于基于非码本的传输，第一个SRI域用来确定第二个SRI域中的元素，且第二个SRI域仅包含与第一个SRI域指示的层数关联的SRI组合。第二个SRI域的比特数N2是由与第一个SRI域关联的所有传输层数中每个传输层的最大码点数量决定的。
在另一种相关技术中，SRI指示域的定义如下表15所示：
表15
Figure PCTCN2022111524-appb-000018
表15与表4的区别点在于，表15固定了在s-TRP和m-TRP传输下第一个SRI/TPMI与第一个SRS资源集合关联，第二个SRI/TPMI与第二个SRS资源集合关联。
目前，上述不同复用方式下对应的可能传输方案，会为PUSCH的上行同时传输定义其中的一种或几种作为调度可选的传输方案。
在相关技术中的m-TRP上行PUSCH增强中，支持S-DCI调度下的终端面向不同TRP发送方向上使用不同的波束即对应TCI state(transmission configuration indication state)进行PUSCH信道重复发送方式的TDM(时分复用技术，time-division multiplexing)方式的分时传输方案。网络可以为不同的TRP发送方向配置关联的不同SRS资源集合，但是要求不同的传输时机TO对应的RANK数目相同，同时不同的SRS资源集合对应的SRS资 源数目相同且SRS端口数相等，对应不同TRP方向实际分配的RANK数也相同，从而导致终端灵活性不够。
因此，本公开为了支持终端多panel基于码本的上行同时传输，需要在保证终端实现灵活性的基础上，考虑S-DCI调度下的不同传输方案对应的预编码指示增强方案。
对于多panel的上行同步传输，基于单DCI的对于PUSCH的一个TB(传输块，Transport Block)的协作传输调度包括多种不同的传输方案，下面对每种传输方案进行简单说明。
一种方案是SDM(Space DivisionMultiplexing，空分)复用方案：PUSCH的一个TB通过不同Panel上分配的各自对应的DMRS端口或端口组合分别面向两个不同的TRP在相同的时频资源上进行发送，不同的panel/TRP/传输时机TO分别和不同的TCI(transmissionconfiguration indicator，传输配置指示)state(状态)即波束相关联。在此基础上，SDM方案又具体分为两种SDM-A和SDM-B，其中，SDM-A:PUSCH的一个TB的不同部分分别通过不同Panel上分配的各自对应的DMRS端口或端口组合分别面向两个不同的TRP在相同的时频资源上进行发送，不同的panel/TRP/传输时机TO分别和不同的TCIstate即波束相关联；SDM-B:PUSCH的对应不同RV版本的同一个TB的重复通过不同Panel上分配的各自对应的DMRS端口或端口组合分别面向两个不同的TRP在相同的时频资源上进行发送，不同的Pane/TRP/传输时机TO分别和不同的TCIstate即波束相关联。
另一种方案是FDM(Frequency DivisionMultiplexing，频分)频分复用方案：PUSCH的一个TB通过不同panel上分配的相同DMRS端口或端口组合分别面向两个不同的TRP在相同时域资源上的不重叠频域资源上进行发送，不同的Panel/TRP/传输时机TO分别和不同的TCI state即波束相关联。在此基础上，FDM方案又具体分为两种FDM-A和FDM-B，其中，FDM-A:PUSCH的一个TB的不同部分分别通过不同Panel上分配的相同DMRS端口或端口组合分别面向两个不同的TRP在相同时域资源上的不重叠频域资源上进行发送，不同的Pane/TRP/传输时机TO分别和不同的TCIstate即波束相关联；FDM-B:PUSCH的对应不同RV版本的同一个TB的重复通过不同Panel上分配的相同DMRS端口或端口组合分别面向两个不同的TRP在相同时域资源上的不重叠频域资源上进行发送，不同的Pane/TRP/传输时机TO分别和不同的TCIstate即波束相关联。
又一种方案是SFN(Single Frequency Network，单频网)复用方案：PUSCH的一个TB通过不同Panel上分配的相同DMRS端口或端口组合分别面向两个不同的TRP在相同的时频资源上进行发送，不同的Pane/TRP/传输时机TO分别和不同的TCIstate即波束相关联。
对于基于终端多panel的上行PUSCH同时传输，会支持上述方案中的一种或多种。
本公开实施例提供的预编码指示方法中，S-DCI调度的DCI中承载有SRI指示域，基 于SRI指示域进行预编码指示增强。
图3根据一示例性实施例示出的一种预编码指示方法的流程图，如图3所示，预编码指示方法用于网络设备中，包括以下步骤。
在步骤S11中，发送S-DCI，S-DCI用于调度终端从多个panel面向多个TRP基于码本的PUSCH传输。
其中，S-DCI调度的DCI中承载有SRI指示域，SRI指示域用于指示PUSCH对应的SRS资源集合中用于PUSCH传输的SRS资源组合，并用于指示终端对应于不同panel/TRP/TCI/PUSCH传输时机(Transmission Occasion，TO)发送PUSCH时使用的空间滤波器。
其中，上行PUSCH传输面向多个基站的TRP方向传输，例如，TDM传输方式下的协作传输，通过时域的不同传输时机(Transmission Occasion，TO)分时向基站的不同TRP发送PUSCH上同一信息的不同重复(repetition)，这种方法对终端能力的要求比较低，不要求支持同时发送波束的能力，而且传输时延较大。
传输时机按照不同的TRP发送方向与不同的panel/TRP/TCI/PUSCH方向相关联。一示例中，SRI指示域指示多TRP发送状态，且对应TRP1&TRP2，则第一组PUSCH传输时机面向TRP1发送(第一个SRS资源集合)，第二组PUSCH传输时机面向TRP2发送(第二个SRS资源集合)。
对于上行来讲，面向不同panel/TRP/TCI的PUSCH信道，实际经过的信道可能空间特性差别很大，因此认为不同的发送方向PUSCH信道的QCL-D不同。
在基于码本的PUSCH传输中，由网络设备决定终端实际传输使用的预编码矩阵(Transmission Precoding matrix indicator，TPMI)和传输层数(Rank Indicator，RI)并通知终端。终端在接下来的上行传输中的数据需要使用网络设备指定的TPMI和RI进行预编码，同时对于预编码后的数据按照SRI指示的SRS资源对应的空间滤波器映射到相应的天线端口上，不同的SRS资源会使用不同的空间滤波器传输，因此终端经过预编码的数据需要经过SRI指示的SRS资源所使用的空间滤波器进行滤波。在本公开实施例中，通过对SRI指示域进行增强设计，实现了对于S-DCI调度的终端对应于不同panel/TRP/TCI/PUSCH TO进行上行同时传输时空间滤波器的指示，进而实现预编码信息的指示。
在本公开实施例提供的一种预编码指示方法中，S-DCI调度的DCI中所包括的SRI指示域为单一SRI指示域。
在本公开实施例提供的一种预编码指示方法中，S-DCI调度的DCI中所包括的SRI指示域为多个SRI指示域。
本公开实施例中，当SRI指示域的数量不同时，SRI指示域指示的PUSCH对应的SRS资源集合中用于PUSCH传输的SRS资源组合不同，与不同SRS资源组合关联的不同panel/TRP/TCI/PUSCH TO不同。
在本公开实施例提供的预编码指示方法的一种实施方式中，S-DCI调度的DCI中所包括的SRI指示域包括单一SRI指示域。该单一SRI指示域用于指示PUSCH对应的SRS资源集合中用于PUSCH传输的SRS资源组合，并用于指示终端对应于不同panel/TRP/TCI/PUSCH TO发送PUSCH时使用的空间滤波器。
其中，S-DCI调度的DCI中所包括的SRI指示域包括单一SRI指示域的情况下，TPMI(传输预编码矩阵)指示域的数量可以是一个也可以是多个。
本公开实施例提供的预编码指示方法中，S-DCI调度的DCI中所包括的SRI指示域包括单一SRI指示域的情况下，可以基于该单一SRI指示域中包括的码点指示不同panel/TRP/TCI/PUSCH TO对应发送PUSCH时分别使用的空间滤波器所对应的SRS资源索引。
一示例中，单一SRI指示域中包括有码点，码点用于指示不同panel/TRP/TCI/PUSCH TO对应发送PUSCH时分别使用的空间滤波器所对应的SRS资源索引。
其中，SRS资源索引用于确定SRS资源索引对应的SRS资源。
示例性的，网络设备为终端配置两个用于码本传输的SRS资源集合，每个SRS资源集合中配置两个SRS资源，则SRI指示域的码点指示表如下表16所示：
表16
Figure PCTCN2022111524-appb-000019
本公开实施例提供的预编码指示方法中，S-DCI调度的DCI中所包括的单一SRI指示域中所包括的码点，可以用于指示单个SRS资源集合，也可以用于指示多个SRS资源集合。
作为一种可能的实现方式，单一SRI指示域中包括有第一码点，第一码点用于指示单个SRS资源集合，单个SRS资源集合或单个SRS资源集合中不同的SRS资源子集合关联 不同panel/TRP/TCI/PUSCH TO。
例如，单个SRS资源集合关联第一panel/TRP/TCI/PUSCH TO和第二panel/TRP/TCI/PUSCH TO。或者，单个SRS资源子集合中包括第一SRS资源子集合和第二SRS资源子集合，第一SRS资源子集合关联第一panel/TRP/TCI/PUSCH TO，第二SRS资源子集合关联第二panel/TRP/TCI/PUSCH TO。
作为另一种可能的实现方式，单一SRI指示域中包括有第二码点，第二码点用于指示多个SRS资源集合，多个SRS资源集合关联不同panel/TRP/TCI/PUSCH TO。
例如，多个SRS资源集合包括第一SRS资源集合和第二SRS资源集合，则第一SRS资源集合关联第一panel/TRP/TCI/PUSCH TO，第二SRS资源集合关联第二panel/TRP/TCI/PUSCH TO。
在本公开实施例提供的预编码指示方法中，单一SRI指示域的比特数基于单一SRI指示域中包含的码点数量确定。其中，码点数量与不同SRI的组合信息之间具有对应关系。
其中，本公开实施例中，码点数量与不同SRI的组合信息之间具有的对应关系为预定义的或由网络设备配置的。
本公开实施例提供的预编码指示方法中，S-DCI调度的DCI中所包括的SRI指示域中的码点用于指示SRS资源集合中SRS资源的数目，S-DCI调度的DCI中所包括的SRI指示域的比特数根据SRS资源集合包括的SRS资源数目确定。一示例中，网络设备可以确定用于上行传输参数的SRS资源集合内的SRS资源数目，并根据确定的SRS资源数目确定SRI指示域的比特数。
例如，若SRI指示域的有效码点数量为5个，则SRI指示域的比特数至少可以是3bit，SRI指示域的取值范围则可以表示为000～111，即对应为0～7；又例如，SRI指示域的有效码点数量为4个，则SRI指示域的比特数至少可以是2bit，SRI指示域的取值范围则可以表示为00～11，即对应为0～3。
其中，预定义的对应关系，例如，协议约定方式，包括提前约定码点与SRS资源集合和/或SRS资源的对应关系，以及无效码点对应特殊处理方式等。网络侧设备配置的对应关系，例如，某一个SRS资源集合内配置的SRS资源数量小于可支持的最大码点的数量时，支持网络侧设备配置上述对应关系。
可选的，一个panel上SRI的组合可以为2和2、3和3或3和4的组合。
一示例中，一个panel上SRI的组合可以为2和3的组合，则码点与SRI的对应关系可以如下表17所示。
表17
Figure PCTCN2022111524-appb-000020
在本公开实施例中，通过配置单个SRI指示域，并基于码点联合指示SRS资源集合来关联不同panel/TRP/TCI/PUSCH TO，使得终端在传输PUSCH时具有多种不同的方案，终端可以灵活选择。
示例性实施例中，通过单一SRI指示域中的SRI codepoint联合指示1个SRS resource set来指示一个beam pair。可以理解的是，该单一SRI指示域的比特数目需要重新定义。
示例性实施例中，通过单一SRI指示域中的SRI codepoint联合指示2个SRS resource set来指示一个beam pair。SRI codepoint中包含的SRI可以是不同表格中具体的SRS index或对应不同表格中的SRI域的codepoint，整体SRI比特数目需要重新定义。
本公开实施例提供的预编码指示方法的另一种实施方式中，S-DCI调度的DCI中所包括的SRI指示域包括多个SRI指示域，多个SRI指示域中的不同SRI指示域分别关联不同panel/TRP/TCI/PUSCH TO方向。
本公开实施例以下为描述方便，将S-DCI调度的DCI中所包括的多个SRI指示域中任意两个不同的SRI指示域称为第一SRI指示域和第二SRI指示域。
示例性的，第一SRI指示域用于指示调度PUSCH的第一SRS资源集合。第二SRI指示域用于指示调度PUSCH的第二SRS资源集合。其中，第一SRI指示域可以理解为是对应第一TRP方向，第二SRI指示域对应第二TRP方向。也即，第一SRI指示域关联第一panel/TRP/TCI/PUSCH TO方向，第二SRI指示域关联第二panel/TRP/TCI/PUSCH TO方向。
在本公开实施例提供的预编码指示方法中，在从单个panel面向单个TRP传输PUSCH的情况下，多个SRI指示域中同一SRI指示域基于SRS资源集合指示域的指示信息关联不同的SRS资源集合。
示例性的，若在单个TRP方向使用第一个SRI指示域，则第一SRI指示域可以关联第一个TRP方向也可以关联第二个TRP方向，也即根据指示信息不同可以关联不同的SRS资源集合。
在本公开实施例提供的预编码指示方法中，关联不同SRS资源集合的同一SRI指示域 的有效比特数基于同一SRI指示域关联的SRS资源集合中包含的SRS资源数目确定。
在本公开实施例提供的预编码指示方法中，不同的TRP方向所关联的SRS资源集合中配置有相同的资源数，且不同多个SRI指示域对应的比特数相同。
示例性的，不同的TRP方向所关联的SRS资源集合中配置有相同的端口数和SRS资源数目。
在本公开实施例提供的预编码指示方法中，多个SRI指示域中不同SRI指示域对应的比特数不同。
在本公开实施例提供的预编码指示方法中，不同SRI指示域对应的比特数基于多个SRI指示域分别关联的不同panel/TRP/TCI/PUSCH TO的SRS资源集合中包含的SRS资源个数确定。
进一步的，SRS资源个数不同对应的SRI指示表格不同。
例如，第一SRI指示域对应的比特数基于第一SRI指示域关联的第一panel/TRP/TCI/PUSCH TO的SRS资源集合中包含的SRS资源个数确定，示例性的对应上述表1；第二SRI指示域对应的比特数基于第二SRI指示域关联的第二panel/TRP/TCI/PUSCH TO的SRS资源集合中包含的SRS资源个数确定，示例性的对应上述表2。
在本公开实施例提供的预编码指示方法中，多个SRI指示域关联的panel/TRP/TCI/PUSCH的对应的SRI码点个数基于不同SRI与SRS资源索引对应关系中指示SRS资源索引确定。
在本公开实施例提供的预编码指示方法中，若多个SRI指示域中包括有第一SRI指示域和第二SRI指示域，第一SRI指示域用于SRS资源集合指示域的指示信息指示的对应SRS资源集合关联的panel/TRP/TCI/PUSCH TO的PUSCH发送使用的空间滤波器，且第一SRI指示域对应有最大比特带宽，最大比特带宽基于多个SRI指示域所指示的SRS资源集合中的SRS资源数确定。第二SRI指示域用于指示第二panel/TRP/TCI/PUSCH TO的PUSCH发送使用的空间滤波器，且第二SRI指示域对应的比特数基于第二SRI指示域所关联SRS资源集合中的SRS资源数确定。
示例性的，第一SRS资源集合配置2个资源，则第一SRI域的比特数为1bit，第二SRS资源集合配置4个资源，则第二SRI域的比特数为2bit，第一SRI域关联第一panel，第二SRI域关联第二panel。对于单TRP场景下，固定通过第一个SRI域指示第一TRP方向或第二TRP方向，若指示第一TRP方向则关联第一SRS资源集合，若指示第二TRP方向则关联第二SRS资源集合，此时1bit不能用于传输，因此第一SRI指示域的比特应该为2bit 才能够支持单TRP场景下的传输。
在本公开实施例中，通过配置SRI指示域的数目以及不同数目下SRI指示域对应的比特数据，实现了SRI指示域的增强，同时通过获取不同panel/TRP/TCI/PUSCH传输时机发送PUSCH时使用的空间滤波器，使终端实现更加灵活的传输PUSCH，进一步的由于终端经过预编码的数据需要经过SRI指示的SRS资源所使用的空间滤波器进行滤波，因此还实现了预编码指示增强。
图4根据一示例性实施例示出的一种预编码指示方法的流程图，如图4所示，预编码指示方法用于终端中，包括以下步骤。
在步骤S21中，接收S-DCI，S-DCI用于调度终端从多个panel面向多个TRP基于码本的PUSCH传输。
