Document Type and Number:
WIPO Patent Application WO/2021/228201
Kind Code:
A1
Abstract:
An apparatus and a method of wireless communication are provided. The method by a user equipment (UE) includes being scheduled, by a base station, with an uplink channel and determining a spatial relation and a pathloss reference signal (RS) for the uplink channel, wherein when the uplink channel comprises a physical uplink shared channel (PUSCH), a default spatial relation and a default pathloss RS can be an RS with quasi co-location (QCL)-Type-D corresponding to a QCL assumption of a control resource set (CORESET) with a lowest identifier (ID). This can solve issues in the prior art, utilize multi-transmission/reception point (TRP) reception, improve uplink reliability, provide a good communication performance, and/or provide high reliability.
