UPLINK PILOT CHANNEL TRANSMISSION TO REDUCE LATENCY OF CIRCUIT SWITCHED FALL BACK

摘要

A method of wireless communication includes initiating a specific call type and transmitting a first random access preamble via a first random access preamble channel when initiating the specific call type. The method also includes transmitting a second random access preamble via a second random access preamble channel when initiating the specific call type. The second random access preamble is transmitted without waiting for a response to the transmitted first random access preamble.
