METHOD AND APPARATUS OF PHYSICAL UPLINK SHARED CHANNEL TRANSMISSION

WIPO Patent Application WO/2021/012845

A1

Methods and apparatuses of physical uplink shared channel (PUSCH) transmission are provided. A method of a PUSCH transmission of a user equipment (UE) includes being configured a list of transmit (Tx) beam candidate identities (IDs) by a base station (BS) and being indicated one of the Tx beam candidate IDs for each PUSCH transmission by the BS. Each of the Tx beam candidate IDs is associated with a reference signal (RS) ID, a control resource set (CORESET) ID, or a physical uplink control channel (PUCCH) resource ID. For one PUSCH transmission, the UE can derive a spatial domain transmission filter according to the RS ID, CORESET ID or PUCCH resource ID that is associated with a Tx beam candidate ID that is indicated for the PUSCH transmission.
