Claim 27:
28. The apparatus of claim 22, wherein communication, with the UE, of the at least one signal associated with the propagation delay between the UE and the network node comprises at least one of to:
transmit, to the UE, a first signal of the at least one signal indicating a transmission time at the network node, wherein the transmission time at the network node for the first signal is earlier than a reception time at the UE for the first signal; or
receive, from the UE, a second signal of the at least one signal indicating a transmission time at the UE, wherein a reception time at the network node for the second signal is later than the transmission time at the UE for the second signal; and
the propagation delay is estimated for the TA based on at least one of a difference between the reception time at the UE for the first signal and the transmission time at the network node for the first signal or a difference between the transmission time at the UE for the second signal and the reception time at the network node for the second signal.
