Downlink channel reception of a wireless communication system

Aspects of the present invention propose a method of receiving a synchronous transmission downlink channel having different spatial quasi-co-location (sQCL) assumptions. The method includes receiving,at a user equipment (UE), a configuration that specifies a monitoring opportunity of a control resource set (CORESET) of a first physical downlink control channel (PDCCH); receiving scheduling or activating a second PDCCH transmitted by a physical downlink shared channel (PDSCH) at the user equipment (UE); determining whether the PDSCH overlaps with the first PDCCH in a time domain; determining whether a first sQCL hypothesis for receiving the first PDCCH is different from a second sQCL for receiving the PDSCH; and when the PDSCH overlaps with the first PDCCH in the time domain and the firstand second sQCLs are different, preferentially receiving the first PDCCH. 本发明的各方面提出了一种具有不同空间准同位(sQCL)假设的同步发送下行链路信道的接收方法。该方法包括在用户设备(UE)处接收配置，其指定第一物理下行链路控制信道(PDCCH)的控制资源集(CORESET)的监测时机，在UE处接收调度或激活物理下行链路共享信道(PDSCH)传输的第二PDCCH，确定该P
