Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a terminal in a wireless communication system is provided. The method includes receiving, from a BS, RRC information configuring a plurality of TCI states for a PDSCH; receiving, from the BS, DCI indicating at least one TCI state from among the plurality of TCI states, wherein the at least one TCI state is associated with a CORESET pool index; and receiving the PDSCH based on the at least one TCI state.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. According to the disclosure, a method and a User Equipment (UE) for enabling reception of plurality of Physical Downlink Control Channel (PDCCH) from plurality of Transmission Reception Points (TRPs) are provided. The method includes receiving, by the UE, at least one Radio Resource Control (RRC) configuration message in relation to at least one TRP of a plurality of TRPs within a cell in a wireless communication system, wherein the at least one RRC configuration message comprises one or more CORESETpoolindex for one or more corresponding CORESETs associated with the at least one TRP, and wherein the at least one RRC configuration message is used to configure the one or more CORESETs and a plurality of search spaces associated with each CORESET, and enabling reception of each PDCCH of a plurality of PDCCH from each TRP of the plurality of TRPs based on the at least one RRC configuration message.

Abstract: The method includes transmitting, at least one user equipment (UE) node, configuration to feedback one or more downlink channel state information (CSI) feedback reports corresponding to one or more Channel state information-Reference signal (CSI-reference signal (RS) port muting patterns to the transceiver node, information regarding the one or more CSI-RS port muting patterns being included in the configuration, receiving, from the at least one UE node, one or more downlink CSI feedback reports, the one or more downlink CSI feedback reports comprising at least one of one or more individual CSI feedback reports corresponding to the one or more CSI-RS port muting patterns, a single multi-CSI feedback report corresponding to the one or more CSI-RS port muting patterns, and one or more CSI feedback reports comprising one or more quantized versions of at least a singular vector decomposition (SVD) decomposed downlink channel matrix corresponding to the one or more CSI-RS port muting patterns, and determining to mute at least one CSI-RS port belonging to at least one of the one or more port muting patterns or to unmute the at least one CSI-RS port belonging to the transceiver node, based on the one or more downlink CSI feedback reports.
