Classification: CPC H | IPC H

Claim 20:
21. The apparatus of claim 15, wherein communication, with the network node, of the at least one signal associated with the propagation delay between the UE and the network node comprises at least one of to:
receive, from the network node, a first signal of the at least one signal indicating a transmission time at the network node, wherein a reception time at the UE for the first signal is later than the transmission time at the network node for the first signal; or
transmit, to the network node, a second signal of the at least one signal indicating a transmission time at the UE, wherein the transmission time at the UE for the second signal is earlier than a reception time at the network node for the second signal, and wherein
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.
