Abstract

Method of digital radio transmission between a base station and a plurality of mobile stations. A time division multiplexed signal frame is generated, including a plurality of time slots which repeat each frame interval. A beginning number of the time slots form a signalling channel with the remaining following time slots forming a plurality of channels which receive data to be sent. The signalling channels include a common organizational connection for each channel of the frame. Additionally, one of the remaining plurality of channels includes an organizational channel for identifying a larger number of channels than those included in the individual frame. The technique permits a combination of time division multiplexing, spectral multiplexing and carrier frequency multiplexing.
