Method and apparatus for transceiving channel related to terminal that supports half duplex transmission in mobile communication system

A user equipment (UE) in a wireless communication system, the UE comprising:

• a transceiver;
• and
• a controller configured to:
• transmit, to a base station via the transceiver, sounding reference signal (SRS) on a first cell, and
• determine not to receive a physical downlink shared channel (PDSCH) on a second cell in a time that overlaps with a transmission time of the SRS on the first cell and in a time that overlaps with a switching time between an uplink and a downlink, in case that the UE is not capable of simultaneous reception and a transmission on the first cell and the second cell.

A user equipment (UE) in a wireless communication system, the UE comprising:

• a transceiver;
• and
• a controller configured to:
• receive, from a base station via the transceiver, first time division duplex (TDD) configuration information for a first cell and second TDD configuration information for a second cell,
• transmit, to the base station via the transceiver, a sounding reference signal (SRS) on the first cell based on the first TDD configuration information, and
• determine, based on the first TDD configuration information and the second TDD configuration information, not to receive a physical downlink shared channel (PDSCH) on the second cell in a time that overlaps with a transmission time of the SRS on the first cell and in a time that overlaps with a switching time between an uplink and a downlink.
