摘要
A User Equipment (UE), and associated method, including a wireless transceiver, configured to perform wireless transmission and reception to and from a cellular station. A controller is configured to use a first preamble to perform a synchronous transmission on a PRACH to the cellular station via the wireless transceiver, and use a second preamble to perform either of at least two different types of transmission, the two different types of transmission comprising an asynchronous transmission and a synchronous transmission to the cellular station via the wireless transceiver; wherein the controller is further configured to receive a random access response to the synchronous transmission from the cellular station via the wireless transceiver, and wherein a Timing Advance (TA) estimation is not required for the synchronous transmission.
