A multi-carrier switching TDMA-TDD microcell telecommunications system

A multicarrier switching time division multiple access-time domain duplex (TDMA-TDD) radio access suitable for the next generation of digital microcellular telecommunications systems is described. In an interference limited environment improved coexistence between slot asynchronous TDMA systems can be effectively achieved by dynamically allocating TDMA slots and carrier frequencies. Signaling channel allocation is focused on the carrier frequency, which gives the advantage of making possible mobile-controlled hand-over and advanced radio channel control for multicarrier TDMA systems. A traffic rate of 16 kbit/s per channel with a frame length of 1 ms is suitable for diversified applications, such as 32 kbit/s to 8 kbit/s codecs and ISDN services
