Abstract

A method is provided for uplink transmission in a wireless communication system. A user equipment (UE) determines whether to transmit both a physical uplink shared channel (PUSCH) and a sounding reference signal (SRS), or drop the SRS and transmit only the PUSCH but dropping the SRS when the UE determines satisfaction of all of at least three conditions including: a first condition specifying that a plurality of timing advance groups (TAGs) including a first TAG and a second TAG are configured, a second condition specifying that at least one symbol of a subframe n which is used to transmit the SRS toward a first cell belonging to the first TAG is overlapped with a subframe n+1 on which the PUSCH is transmitted toward a second cell belonging to the second TAG and a third condition specifying that a total uplink transmission power exceeds a maximum value.
