Abstract
A method is described for uplink transmission in a wireless communication system. A user equipment determines whether to transmit or drop a sounding reference signal (SRS) on a last symbol in an ith subframe. The determination is performed if multiple timing advance groups (TAGs) are configured and if a portion of the last symbol of the ith subframe for the SRS transmission toward the a serving cell in a first TAG is overlapped with an (i+1)th subframe for transmitting an uplink channel toward a second serving cell in a second TAG.
