Abstract (en)

[origin: WO2020086572A1] Embodiments of a User Equipment (UE) and methods of communication are generally described herein. The UE may receive control signaling that configures one or more control resource sets (CORESETs). Each of the CORESETs may be allocated for reception of one or more physical downlink control channels (PDCCHs). Each of the CORESETs may be associated with a CORESET identifier (CORESET-ID). The UE may determine that reception of a physical downlink shared channel (PDSCH) scheduled by one of the PDCCHs is to be performed based on quasi-colocation (QCL). The UE 102 may determine the QCL based on Transmission Configuration Indication (TCI), CORESET-ID and/or other factors. The UE may receive the PDSCH in accordance with the determined QCL.
