通信系统中，当高层配置上行物理共享信道(Physical Uplink Shared Channel，PUSCH)工作在码本(codebook)传输模式时，仅支持单个下行控制信息(single DCI)调度的PUSCH传输关联一个探测参考信号(Sounding Reference Signal，SRS)资源(resource)。
为了支持PUSCH在多发送接收点或面板(Multi-TRP/panel)传输，即PUSCH可能通过时分方式在不同的面板上切换发送，如果继续采用single DCI调度PUSCH，则该PUSCH传输在某些情况下要关联多个SRS资源，不同的SRS资源配置不同的空间关系信息。为了提高PSUCH传输可靠性，PUSCH可以配置重复发送方式，不同的PUSCH重复关联不同的SRS资源；当其中一个SRS资源对应的无线链路较差时，传输可靠性将无法保证。

第四方面，提供一种资源配置装置，应用于网络侧设备，包括：

第八方面，提供一种程序产品，所述程序产品被存储在非易失的存储介质中，所述程序产品被至少一个处理器执行以实现如第一方面或第二方面所述的处理的方法的步骤。
第九方面，提供了一种芯片，所述芯片包括处理器和通信接口，所述通信接口和所述处理器耦合，所述处理器用于运行程序或指令，实现如第一方面或第二方面所述的处理的方法。
在本申请实施例中，DCI调度的PUSCH传输可以关联一个或多个SRS资源，满足终端的动态的PUSCH传输的需求，进一步地，在PUSCH传输与多个SRS资源关联时，每个SRS资源侦听不同的无线信道，PUSCH传输可以在不同的无线信道上采用重复(repetition)的方式进行传输提高性能。

也就是，每个PTRS资源关联一组DMRS端口，并且每组DMRS端口数固定为2，并按照一定的挑选规则确定。其中挑选规则可以是直接规定所有调度的DMRS端口中的前两个或者后两个，或者通过高层信令通知组内的DMRS端口值。

如果终端根据DCI的SRI域息得知PUSCH传输与一个SRS resource关联，则终端根据该PTRS DMRS关联域的N bit指示，获得PTRS端口和DMRS端口的关联关系。如果N bit指示信息大于2bit，则终端只解读其中的2bit信息(例如最低位或者最高位的2bit)，其他bit信息不解读。
可选地，所述第一PTRS资源的端口和第二PTRS资源的端口的配置包括：如果所述终端的PTRS资源的最大端口数为N，则所述第一PTRS资源和第二个PTRS资源的最大端口数为N，N等于1或2；或者，如果所述终端的PTRS资源的最大端口数为N，PTRS端口0的PTRS资源是第一PTRS资源，PTRS端口1的PTRS资源是第二个PTRS资源，N等于2。
可选地，所述终端的PTRS资源的最大端口数由高层信令指示，或者基于接收到的所述DCI中的宽带预编码矩阵指示(TPMI)的相干(coherent)特性确定。
例如，指示TPMI码本只是全相干(full coherent)的码本集合，则PTRS的端口数为1；如果指示TPMI码本是部分(partial)或非相干(non coherent)的码本集合，PTRS的端口数为2。

参见图3，本申请实施例提供一种资源配置方法，由网络侧设备执行，包括：

在本申请实施例中，所述方法还包括：发送第一信息，其中，所述第一信息指示所述PUSCH传输与一个或多个SRS资源关联，所述DCI中SRI 域的长度为0比特。
在本申请实施例中，所述DCI的PTRS DMRS关联域指示PTRS端口和关联不同SRS资源的DMRS端口的关联关系。
可以理解的是，网络侧设备侧的方法实施例与终端侧的方法实施例相同的内容，可以参考之前的描述，在此不再敷述。
在本申请实施例中，DCI调度的PUSCH传输可以关联一个或多个SRS资源，满足终端的动态的PUSCH传输的需求，进一步地，在PUSCH传输与多个SRS资源关联时，每个SRS资源侦听不同的无线信道，PUSCH传输可以在不同的无线信道上采用重复的方式进行传输提高性能。
下面结合本申请实施例一和本申请实施方式二进行介绍。
本申请实施例一：
当前PUSCH配置codebook的传输模式，高层只配置一个用于codebook功能的SRS resource set，并且PUSCH只能关联该SRS resource set内其中的一个SRS resource。为了增强PUSCH可靠性传输，PUSCH可以关联两个SRS resource，每个SRS resource侦听不同的无线信道，PUSCH可以在不同的无线信道上采用repetition的方式进行传输提高性能。
一种实施例，高层还是只配置一个用于codebook功能的SRS resource set，但是高层通过其他参数显示指示UE，“PUSCH传输与两个SRS resource关联”的功能开启。此时该SRS resource set必须配置两个SRS resource，并通过DCI中的SRI域动态指示PUSCH是关联一个SRS resource还是同时关联两个SRS resource，这样可以动态的匹配无线信道变化。例如当基站检测到其中一个SRS resource侦听的无线信道质量很差时，下次DCI的SRI域可以指示另一个SRS resource用于PUSCH传输。
另一种实施例，如果高层没有配置参数指示UE PUSCH关联两个SRS resource传输，还可以根据RRC中配置的用于codebook功能的SRS resource set的个数隐式指示“PUSCH传输与两个SRS resource关联”的功能开启。例如当SRS resource set的个数是1时，是已有技术，当SRS resource set的个数是2时，UE认为是PUSCH可以关联两个SRS resource传输。
本申请实施方式二：
配置一个PTRS-DMRS association域，其bit信息联合指示两个PTRS资源和对应的DMRS port的关联关系，其中每个PTRS资源关联多个SRS resource。如果UE根据DCI的SRI域得知PUSCH传输与两个SRS resource关联，并且高层信令给每个PTRS资源最大port数配置为1。
(1)如果UE最大传输rank限制为2，则PTRS-DMRS association域用2bit表示。有两种可能的表示方式：
方式1：其中1bit用于指示第一个PTRS的唯一port是和第一个还是第二个调度的DMRS port关联，其中该DMRS在第一个SRS resource关联的PUSCH occasion上发送；另一个1bit用于指示第二个PTRS的唯一port是和第一个还是第二个调度的DMRS port关联，其中该DMRS在第二个SRS resource关联的PUSCH occasion上发送，见表3所示。
表3：
Figure PCTCN2021124956-appb-000003
方式2：2bit指示4种情况，每种情况包括两个PTRS资源的port分别和DMRS port的关联关系，见表4所示。
表4：

Figure PCTCN2021124956-appb-000005
(2)：如果UE最大传输rank限制为4，当PTRS-DMRS association域用4bit表征时，有两种可能的表示方式：
方式1：前2个bit用于指示第一个PTRS的唯一port是和哪个DMRS port关联，其中该DMRS在第一个SRS resource关联的PUSCH occasion上发送；后2个bit用于指示第二个PTRS的唯一port是和哪个DMRS port关联，其中该DMRS在第一个SRS resource关联的PUSCH occasion上发送，见表5所示。
表5：
