A User Equipment (UE) including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a cellular station. The controller uses one or more first preambles within a PRACH time-frequency resource to perform a synchronous transmission on the PRACH to the cellular station via the wireless transceiver, or uses one or more second preambles within the PRACH time-frequency resource to perform an asynchronous transmission or a synchronous transmission on the PRACH to the cellular station via the wireless transceiver.
