DOWNLINK CHANNEL RECEPTION IN WIRELESS COMMUNICATION SYSTEM

Title:

DOWNLINK CHANNEL RECEPTION IN WIRELESS COMMUNICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2019/154344

Kind Code:

A1

Abstract:

Aspects of the disclosure provide a method for reception of simultaneously transmitted downlink channels having different spatial quasi-co-location (sQCL) assumptions. The method can include receiving a configuration specifying a control resource set (CORESET) monitoring occasion of a first physical downlink control channel (PDCCH) at a user equipment (UE), receiving a second PDCCH scheduling or activating transmission of a physical downlink shared channel (PDSCH) at the UE, determining whether the PDSCH overlaps the first PDCCH in time domain, determining whether a first spatial quasi-co-location (sQCL) assumption for reception of the first PDCCH and a second sQCL assumption for reception of the PDSCH are different, and prioritizing the reception of the first PDCCH when the PDSCH overlaps the first PDCCH in time domain and the first and second sQCL assumptions are different.
