Abstract
A method performed by a user equipment (UE) for multiple transmission and reception points (multi-TRP) based physical uplink shared channel (PUSCH) transmission is provided. The method includes receiving, from a base station (BS), a Radio Resource Control (RRC) parameter that enables the UE to derive a default uplink (UL) spatial filter for PUSCH transmission; receiving, from the BS, a downlink control indication (DCI) format 0_0 that schedules the PUSCH transmission on a serving cell; determining one or two default UL spatial filters for the PUSCH transmission; and applying the one or two default UL spatial filters to perform the PUSCH transmission.
