Abstract: According to present disclosure, there is provided a method for repetitive transmitting physical uplink shared channel (PUSCH) to a multiple transmission and reception point (mTRP) performed by a user equipment (UE). The method comprises receiving, from a base station, downlink control information (DCI) including phase tracking reference signal (PTRS)—demodulation reference signal (DMRS) association information; based on the PTRS-DMRS association information, determining PTRS port for each sounding reference signal (SRS) resource set among a plurality of SRS resource set; and based on the determined PTRS port, transmitting PTRS.

Abstract: The disclosure relates to a pre-5G or 5G communication system to be provided for supporting higher data rates beyond a 4G communication system, such as LTE. A method includes receiving, by a UE, PDCCH information from a network entity, where the PDCCH information includes DCI and PDSCH information, and determining, by the UE, the default beam behavior based on a CORESET with a lowest ID among first and second CORESETs, in response to determining that a TCI state is not present in the DCI and the scheduling offset between reception of all transmission occasions of DL DCI and the corresponding PDSCH information of the serving cell is greater than or equal to the threshold.
