1. A method, in a network node, for aligning sending of a network system clock time to a wireless device with initiating a propagation delay compensation procedure for the wireless device, the method comprising:
determining that a propagation delay compensation procedure to adjust uplink transmission timing for the wireless device is to be initiated or has been initiated;
and, responsive to said determining, sending an indication of a network system clock time to the wireless device in association with the propagation delay compensation procedure;
wherein the propagation delay compensation procedure comprises a timing advance procedure and wherein the method further comprises:
determining that the wireless device is able to receive enhanced timing advance values, the enhanced timing advance values reflecting smaller variations in uplink synchronization than provided to wireless devices unable to receive enhanced timing advance values; and
providing the wireless device with an enhanced timing advance value as part of the timing advance procedure.
