Digital radio transmission system with a connection-accompanying organization channel in the time-division multiplex frame
First Claim
1. A digital radio transmission system in which base stations (BS) and a multiplicity of mutually independent mobile stations (MS) are arranged in a cellular network, and in which the messages for transmission in a common transmission channel are time division multiplexed together wherein, in the transmission direction from the base station (BS) to a respective mobile station (MS) an organization channel accompanying the transmission is provided within the time-division multiplex frame as a central organizatuion channel common to all time multiplexed channels of said multiplex frame for connection data for each data channel contained in said frame.

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.

4. A method of digital radio transmission between a base station and a plurality of mobile stations, comprising:
-
generating a time division multiplexed signal frame comprising a plurality of time slots which repeat each frame interval, a beginning number of said time slots forming a signalling channel, the remaining time slots comprising a plurality of data channels; inserting data in each of said remaining time slots forming data channels to be sent to said plurality of mobile stations; inserting signalling data in said beginning number of said time slots of each frame which signalling data includes a common organizational connection for all channels of said frame; and
,inserting data into one of said remaining time slots which comprise a central organization channel which is common to a larger number of channels than said channels which include said common organizational connections. - View Dependent Claims (5, 6, 7)
