Abstract
Embodiments disclosed herein relate to a method in a wireless communication device that operates in an enhanced coverage mode, the enhanced coverage mode comprising sequential repetition of messages sent from the wireless communication device to a network node. An example method includes: receiving a Timing Advance Command TAC from the network node; and adapting a time at which the TAC is applied, wherein a time difference between the time at which the TAC is applied and a time at which the TAC is received shall be greater than or equal to a specified time depending on a type of the used Radio Access Technology, such that application of the TAC does not occur during a period after a first subframe of a repeated uplink transmission till the end of the repeated uplink transmission.
