Abstract

One or more embodiments herein relate to a method for an uplink transmission timing adjustment in a wireless communication device served by a network node and configured to operate in a coverage enhancement mode. The coverage enhancement mode comprises a repetitive transmission of a first uplink signal during a first repetition period. The method comprises determining a change in a downlink timing (210), determining whether the first repetition period is ongoing (240); and in response to the change in the downlink timing and the first repetition period being ongoing, performing an adjustment of an uplink transmission timing outside the first repetition period (260).
