1. A method performed by a terminal in a time division duplex (TDD) communication system, the method comprising:
identifying that the terminal indicates support of half-DuplexTDD-CA-SameSCS capability;
identifying that directionalCollisionHandling is configured as ‘enabled’ for a set of serving cells among multiple serving cells including a first serving cell and a second serving cell, in case that the terminal is not capable of simultaneous reception and transmission on the first serving cell and the second serving cell;
identifying that the terminal is not configured to monitor a physical downlink control channel (PDCCH) for downlink control information (DCI) format 2_0 on any of the multiple serving cells;
identifying a first carrier of the first serving cell not configured for a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH) transmission; and
in case that a sounding reference signal (SRS) transmission on the first carrier of the first serving cell and a physical channel transmission on a second carrier of the second serving cell collide and directionalCollisionHandling is configured as ‘enabled’ for the set of serving cells, applying a priority rule for the SRS transmission and then applying a procedure for directional collision handling.
