A Time Rese Capture Access (TRCA) Protocol for PCS and Wireless ATM Applications

摘要

The Time Reuse Capture Access (TRCA) protocol is medium access control protocol appropriate for personal communications and wireless Asynchronous Transfer Mode (ATM) applications. It is based on time reuse rather than frequency reuse. Frequency channels are reused in every cell (freqency reuse one). Each FDMA channel has a TDMA frame structure. The number of slots in the frame is equal to the time reuse factor and each slot is assigned to a specific cell in the reuse cluster. Each mobile user transmits in its assigned frequency channel and TDMA time slot which corresponds to the cell it currently belongs. The protocol also exploits the power capture phenomenon in which simultneous transmissions of users of users in adjacent cells may be successfully received.
