Design of common access channels for TDMA-TDD microcell communications systems

This paper describes a detailed design of common access channels in the down link which are constructed with two transmission frames, multi-frame and super-frame, on a dedicated control carrier frequency in TDMA-TDD systems. The co-channel interference between TDMA-TDD bursts is discussed as the first consideration in the design of multi-frame. For the super-frame design, the average connection delay in a call control sequence is evaluated for the various period of super-frame as a function of offered traffic. A method of designing the optimum common access channels transmission frames is proposed.<>
