TIME DIVISION MULTIPLE ACCESS RADIO SYSTEMS

摘要

A method of operating a time division multiple access (TDMA) radio system having multi-slot capabilities and utilising half-duplex transmission/reception where uplink and downlink user data transmissions between a mobile station (MS) (2) and a base station (BS) (3) are made in separate TDMA frames. A greater number of time slots are allocated to the mobile station (2) in each downlink TDMA frame than in each uplink TDMA frame to improve the efficiency of radio resource allocation and of the radio module (4) of the mobile station (2).
