1. A method performed by a user equipment (UE) in a communication system, the method comprising:
transmitting, to a base station, UE capability information including beam switching-related information;
receiving, from a first transmission reception point (TRP) associated with the base station, first configuration information including first information related to a first control channel;
receiving, from a second TRP associated with the base station, second configuration information including second information related to a second control channel;
receiving, from the first TRP, first control information based on the first information related to the first control channel;
receiving, from the second TRP, second control information based on the second information related to the second control channel;
identifying whether a first time offset between the first control channel and a first data channel corresponding to the first control information is smaller than the beam switching-related information;
identifying whether a second time offset between the second control channel and a second data channel corresponding to the second control information is smaller than the beam switching-related information;
identifying default quasi co-located (QCL) information configured by a medium access control (MAC) control element (CE);
in case that the first time offset and the second time offset are smaller than the beam switching-related information, selecting a QCL parameter among a first QCL parameter used to receive the first control information and a second QCL parameter used to receive the second control information; and
based on the identified default QCL information, receiving data on the first data channel and the second data channel by applying the selected QCL parameter to the identified default QCL information,
wherein the default QCL information includes at least one of information associated with transmission configuration indication (TCI) states, downlink reference signals (DL-RS), or uplink reference signals (UL-RS).
