Abstract

A control channel structure for time-division multiple access (TDMA) mobile radio systems that must offer high system capacity and ISDN services is described. This structure overcomes the difficulties in random access efficiency and the application of a layered protocol. A functional channel definition and layered signaling frame format are described. Functional channel mapping on physical channels is then described. Several methods for the frequency assignment of control channels are compared from the points of radio channel efficiency and functional ability. The optimum method is determined. Mapping information is broadcast to realize the control channel structure needed. An improved random access scheme for the common control channel is proposed. This scheme obtains good throughput performance, and realizes the application of data link layer protocols. Thus, efficient and flexible signaling for radio link control and data services is achieved
