Description

一种信息确定方法/装置/设备及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及信息确定方法/装置/设备及存储介质。
背景技术
在多输入多输出(Multiple-Input Multiple-Output，MIMO)系统中，引入了多个发送接收点(transmission reception Point，TRP)在具有ideal backhaul(理想回程)连接的情况下所实现的相干联合传输(coherent joint transmission，CJT)。以及，目前针对于统一传输配置指示状态(Unified Transmission Configuration Indicator state，unified TCI state)已经考虑了Single-TRP(单TRP，S-TRP)的情况。具体的，unified TCI state即针对一个TRP的多个信道/信号指示同一套TCI state，其中，同一套TCI state目前可能是上行和下行分开指示，即分别指示DL(下行)TCI state和/或UL(上行)TCI state，或者上下行联合指示，即指示joint(联合)TCI state。以及，终端设备可以基于指示的joint TCI state来用于上行信道和/或上行信号的传输。
相关技术中，MIMO目前最多可支持4个TRP的CJT，则网络设备会向终端设备指示到3个或4个TCI state。但是，目前只讨论了当网络设备指示1个或2个TCI state时，终端设备确定哪个TCI state用于上行信道和/或上行信号传输的方法，因此，相关技术中的方法无法适用于网络设备指示了3个或4个TCI state这一场景下的终端设备确定具体使用哪个TCI state用于上行信道和/或上行信号传输时的确定过程。

以及，在本公开的一个实施例之中，当要确定用于特定PUCCH或特定PUSCH传输的TCI state时，也可以采用图10实施例的方法来确定。
其中，该特定PUCCH或特定PUSCH可以为：被配置为了时分复用重复(Time-divisionmultiplexing repetition，TDM repetition)、单频网(single frequency network，SFN)、空分复用重复(Space Division Multiplexing repetition，SDM repetition)、频分复用重复(Frequency Division Multiplexing repetition，FDM repetition)等传输方法的PUCCH或PUSCH；或者
其中，上述的TDM repetition可以理解为：重复传输的两个资源可以对应同样的频域资源，但是对应不同时域资源，且对应不同的TCI state；上述的SFN可以理解为：重复传输的两个资源可以对应同样的时域和频域资源，相同的DMRS端口，但对应不同的TCI state；上述的SDM repetition可以理解为：重复传输的两个资源可以对应同样的时域和频域资源，但对应不同的DMRS端口组以及对应不同的TCI state；上述的FDM repetition可以理解为：重复传输的两个资源可以对应同样的时域资源，但是对应不同的频域资源以及对应不同的TCI state。
综上所述，本公开提供的信息确定方法之中，终端设备会确定用于上行信道传输和/或上行信号传输的TCI state，其中，本公开的方法中，该信息确定方法可以是应用于最多可支持4个TRP/RRH的CJT的MIMO系统中。由此可知，本公开的方法主要用于3个TRP/RRH的CJT或4个TRP/RRH的CJT的场景，当然，也适用于2个TRP/RRH的CJT。也即是，本公开针对于网络设备指示了3个或4个TCI state的这一情形，提供了一种终端设备确定具体使用哪个TCI state用于上行信道传输和/或上行信号传输的方法，从而提高了基于Multi-TRP相干联合传输的传输性能。
图11为本公开实施例所提供的一种信息确定方法的流程示意图，该方法由终端设备执行，如图11所示，该信息确定方法可以包括以下步骤：
步骤1101、基于调度上行信道和/或上行信号的DCI所对应的控制资源集(CORESET)的TCI state确定用于上行信道传输和/或上行信号传输的TCI state。
其中，在本公开的一个实施例之中，基于调度上行信道和/或上行信号的DCI所对应的CORESET的TCI state确定用于上行信道传输和/或上行信号传输的TCI state的方法可以包括：
若调度上行信道和/或上行信号的DCI所对应的CORESET仅对应一个TCI state，则直接将该一个TCI state确定为用于上行信道传输和/或上行信号传输的TCI state；若调度上行信道和/或上行信号的DCI所对应的CORESET对应了多个TCI state，则将该多个TCI state中的其中一个TCI state或其中多个TCI state或全部TCI state确定为用于上行信道传输和/或上行信号传输的TCI state。
此外，在本公开的一个实施例之中，图11实施例的方法可以适用于针对利用DCI调度的上行信道和/或上行信号确定其传输所用的TCI state。但是，需要说明的是，针对DCI format 0_0调度的PUSCH而言，由于DCI format 0_0为fallback(回退)DCI，其所包含的指示域较少，因此，调度PUSCH的DCI format 0_0没有足够的指示域来指示TCI state，则调度PUSCH的DCI format 0_0无法指示TCI state，由此，当针对DCI format 0_0调度的PUSCH指示其传输所用的TCI state时，通常需要使用其它DCI指示或MAC CE或RRC指示，或默认规则或基于DCI format 0_0对应的CORESET的TCI state确定。
综上所述，本公开提供的信息确定方法之中，终端设备会确定用于上行信道传输和/或上行信号传输的TCI state，其中，本公开的方法中，该信息确定方法可以是应用于最多可支持4个TRP/RRH的CJT的MIMO系统中。由此可知，本公开的方法主要用于3个TRP/RRH的CJT或4个TRP/RRH的CJT的场景，当然，也适用于2个TRP/RRH的CJT。也即是，本公开针对于网络设备指示了3个或4个TCI state的这一情形，提供了一种终端设备确定具体使用哪个TCI state用于上行信道传输和/或上行信号传输的方法，从而提高了基于Multi-TRP相干联合传输的传输性能。
