具体实施方式
下文中将结合附图对本申请的实施例进行说明。以下结合实施例附图对本申请进行描述，所举实例仅用于解释本申请，并非用于限定本申请的范围。
在相关技术中的通信协议中，定义了一种控制信道，即PDCCH，该PDCCH可以用于：向UE发送下行调度信息以便UE接收物理下行共享信道(Physical Downlink Shared Channel，PDSCH)；向UE发送上行调度信息以便UE发送物理上行共享信道(Physical Uplink Shared Channel，PUSCH)；发送CSI上报请求以及发送上行功控命令等。PDCCH上所携带的信息称为DCI。终端无法事先获得DCI传输的精确时频位置，而只能在一个大致的资源范围内对DCI进行搜索，这个过程也称为盲检测(Blind Detection)。协议中规定，基站侧发送一个DCI，该DCI承载在PDCCH上，UE检测到PDCCH之后，并在s个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号的时间内完成对DCI的处理。这个时间长度s是基站通过信令配置给UE处理DCI的限制条件。
在DCI上有一个信息域称为CSI请求，在基站需要获取终端的CSI的情况下，需要触发CSI请求。对于终端而言，处理CSI是复杂度相对较高的信号处理过程，需要付出较大的计算资源和一定的计算时间，因此，在为了实现上述CSI反馈的基本流程，终端和基站需要就终端的计算能力、处理时延达成一致的理解。
然而，相关技术中的DCI处理和CSI处理在支持MTRP传输方面存在一些问题，基站配置给UE的DCI处理时间和CSI处理时间不足，导致UE无法正确解调DCI和上报准确的CSI。
本申请实施例提供一种信息传输方法，基站通过配置DCI相关处理参数，并发送至终端，以使终端按照DCI相关处理参数对DCI和CSI进行处理。

在一实施例中，以对一个DCI进行处理，以及一个CSI进行上报，以及第一通信节点为基站(比如，包括：TRP1和TRP2)，第二通信节点为终端为例，对DCI相关处理参数的配置过程进行说明。图3是本申请实施例提供的一种MTRP场景的示意图。在MTRP场景中，基站侧配置K s个用于信道测量的信道测量资源(CMR)，其中基站侧TRP1配置了一个group，记为CMR group1，包含K 1个CMR。基站侧TRP2配置了配置了另一个group，记为CMR group2，包含K 2个CMR，且满足K 1+K 2＝K s。基站侧通过信令配置参数N，N表示MTRP场景中CMR的配对数量，每对CMR pair中的CMR分别来自不同的CMR group。如图3所示，基站侧共配置了8个CMR，CMR group1中包含4个CMR，从TRP1上发送，CMR group2中包含4个CMR，从TRP2上发送。在N＝1的情况下，CMR group1中有一个CMR与CMR group2中的一个CMR形成配对关系。
基站侧可以通过信令配置CMR的共享关系，表示配对的CMR是否可以用于STRP的CSI测量。在共享关系使能的情况下，表示配对的CMR既可以用于MTRP的CSI测量，也可以用于STRP的CSI测量；在共享关系不使能的情况下，表示配对的CMR仅可以用于MTRP的CSI测量，无法用于STRP的CSI测量。
