Description

一种下行信号的传输方法及终端设备 技术领域
本申请实施例涉及通信技术领域,具体涉及一种下行信号的传输方法及终端设备。
背景技术
在新无线(New Radio,NR)***中,为了增加下行传输的吞吐量,可以部署多个传输点(Transmission/Reception Point,TRP)独立给终端设备调度和传输下行数据。终端设备需要在一个时间单元例如,一个时隙、一个符号或多个符号等内同时检测多个下行控制信息(Downlink Control Information,DCI),每个DCI对应独立的物理下行共享信道(Physical Downlink Shared Channel,PDSCH),从而分别检测对应的PDSCH。
不同DCI所调度的PDSCH可以在同一个检测窗口例如,一个时隙或一个正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号等内传输,由于每个PDSCH都对应有自己的接收波束,如果这些PDSCH的接收波束不同,终端设备需要采用不同的接收波束接收这些PDSCH。
然而,在某些情况下,例如,终端设备只具有一个天线阵列等,终端设备在同一个检测窗口内可能只能采用一个接收波束接收PDSCH。因此,终端设备如何进行多个PDSCH的接收是亟需解决的一个问题。类似地,物理下行共享信道(Physical Downlink Shared Channel,PDSCH)、信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)等其他下行信号也存在类似的问题。

图2是本申请实施例提供的一种下行信号的传输方法200的示意性图。
210、终端设备确定需要在第一检测窗口内接收至少两个下行信号。
220、所述终端设备根据所述至少两个下行信号的传输信息,确定所述至少两个下行信号的接收方式;其中,所述传输信息包括所述至少两个下行信号的调度信息、传输配置或者所携带的信息中的至少一项。
230、所述终端设备根据所述至少两个下行信号的接收方式,在所述第一检测窗口内,接收所述至少两个下行信号中至少一个下行信号。
需要说明的是,本发明所涉及的所述下行信号可以包括但不限于物理下行共享信道(Physical Downlink Shared Channel,PDSCH)、物理下行控制信道(Physical Downlink Control Channel,PDCCH)或者信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS),本实施例对此不进行特别限定。
可选地,在本实施例的一个可能的实现方式中,所述传输配置可以包括但不限于:
接收对应下行信号所采用的接收波束;和/或
接收对应下行信号所采用的准同址(Quasi-Co-Located,QCL)类型D(type D)的参考信号;和/或
接收对应下行信号所采用的传输配置指示(Transmission Configuration Indicator,TCI)状态;和/或
接收对应下行信号所假设的映射类型;和/或
接收对应下行信号所用的时间窗口。
可选地,在本实施例的一个可能的实现方式中,所述至少两个下行信号中每个下行信号可以由独立的下行控制信息(Downlink Control Information,DCI)调度。对于非周期的CSI-RS,可以由独立的DCI触发。
具体地,所述独立的DCI可以是在不同时间接收到的DCI,或者还可以是采用不同的DCI格式的DCI,本实施例对此不进行特别限定。
可选地,在本实施例的一个可能的实现方式中,所述至少两个下行信号中不同下行信号所占用的物理资源存在重叠(overlapping),因此,终端设备则不能在第一检测窗口中同时接收所述这些PDSCH。
可选地,在本实施例的一个可能的实现方式中,所述至少两个下行信号中不同下行信号具有不同的传输配置,因此,终端设备在第一检测窗口中只能采用一种传输配置进行接收,不能采用各个PDSCH各自的传输配置来接收各个PDSCH。
例如,所述至少两个下行信号中不同下行信号的传输配置指示(Transmission Configuration Indicator,TCI)状态包含的参考信号不同。
或者,再例如,所述至少两个下行信号中不同下行信号的TCI状态中包含的准同址(Quasi-Co-Located,QCL)类型D(type D)的参考信号不同。

例如,以PDSCH作为下行信号的举例,第一检测窗口可以是一个时隙。如果终端设备在一个时隙被调度了多个PDSCH,且多个PDSCH所占用的物理资源存在重叠,则终端设备可能无法同时解调出多个PDSCH,需要明确接收的优先级。如果终端设备在一个时隙被调度了多个PDSCH,且多个PDSCH的QCL type D的参考信号不同(即需要采用不同的接收波束接收),则终端设备可能无法在该时间窗口内同时采用多个接收波束接收这些PDSCH,而只能采用单个接收波束来接收,此时需要明确接收的优先级。
或者,再例如,以PDSCH作为下行信号的举例,第一检测窗口可以是终端设备检测到一个DCI到该DCI调度的PDSCH传输完成之间的一个时间窗口,如果终端设备在该时间窗口内接收到另一个DCI需要在该时间窗口内传输另一个PDSCH,则终端设备就需要在该时间窗口内同时接收两个PDSCH,且这两个PDSCH的传输配置可能是不同的,终端设备不一定有时间能够在该时间窗口内进行传输配置的切换,需要明确接收的优先级。
或者,再例如,以PDSCH作为下行信号的举例,第一检测窗口可以是时间长度为T的一个时间窗口,其中T为终端设备切换接收波束所需要的时间。如果终端设备需要在一个时间窗口内同时接收两个PDSCH,且这两个PDSCH的QCL type D的参考信 号不同(即需要采用不同的接收波束接收),则终端设备可能无法在该时间窗口内同时采用不同接收波束接收这两个PDSCH,需要明确接收的优先级。
可选地,在本实施例的一个可能的实现方式中,在220中,所述终端设备具体可以根据所述至少两个下行信号的传输信息,确定是否接收所述至少两个下行信号中至少一个下行信号,或者还可以根据所述至少两个下行信号的传输信息,确定接收所述至少两个下行信号中至少一个下行信号所采用的传输配置,本实施例对此不进行特别限定。
