Abstract

Some of the example embodiments presented herein are directed towards a user equipment (501) and corresponding method therein for uplink timing alignment. The user equipment (501) may initiate a timing advance value to zero during a creation of a timing advance group a modification of a timing advance group or if a TAC MAC CE command has not been performed. The user equipment (501) may further update the timing advance value based on a received TAC MAC CE command. Some of the example embodiments presented herein are directed towards a base station and corresponding method therein for uplink timing alignment. The base station (401) may be configured to estimate a proximity of the user equipment (501) to an uplink receive or an uplink cell size of the user equipment. The base station may determine a TAC MAC CE based on the estimation and send the TAC MAC CE to the user equipment (501 ) for uplink timing alignment.
