Apparatus and methods for UL transmission in multi-TRP scenarios

Abstract

This disclosure provides apparatus and methods for UL transmission in a multi-TRP scenario. An apparatus for a UE may include: an RF interface circuit configured to receive a DCI from a TRP for scheduling PUCCH transmissions to multiple TRPs; and a processing circuit coupled to the RF interface circuit and configured to: encode and multiplex multiple PUCCH repetitions targeting multiple TRPs on one or more PUCCH resources based on PUCCH repetition-related configuration information indicated by the DCI or higher-level signaling; and provide the encoded and multiplexed PUCCH repetitions to the RF interface circuit for transmission to multiple TRPs via one or more PUCCH resources.
