1. A method of a user equipment (UE) in a communication system, the method comprising:
receiving a radio resource control (RRC) message including information associated with a first maximum number of multi-input-multi-output (MIMO) layers from a base station, wherein the information associated with the first maximum number of MIMO layers is set for each serving cell of the UE;
identifying whether information associated with a second maximum number of MIMO layers related to a downlink bandwidth part (BWP) is configured based on the RRC message, wherein the information associated with the second maximum number of MIMO layers is set for each BWP configured for the UE;
in case that the information associated with the second maximum number of MIMO layers related to the downlink bandwidth part is configured, using the second maximum number of MIMO layers for a physical downlink shared channel (PDSCH); and
in case that the information associated with the second maximum number of MIMO layers related to the downlink bandwidth part is not configured, using the first maximum number of MIMO layers for the PDSCH.
