A TDMA signal of frames of a nominal duration and having time slots is demodulated (120, 150, 160). A time slot assignment circuit (170) assigns and re-assigns time slots in a present and next frame based on TDMA control information.

A TDMA signal of frames of a nominal duration and having time slots is demodulated (120, 150, 160). A time slot assignment circuit (170) assigns and re-assigns time slots in a present and next frame based on TDMA control information. A real-time timing control circuit (180) determines a recovered-data duration for production of recovered data by a data decoder (190). The data decoder (190) produces the recovered-data during the receive-data duration by time compression or expansion during the next frame when a different time slot is re-assigned by the time slot re-assignment circuit (170).

[ What is claimed is:] [1.] A communication device for receiving a received time division signal of frames having time slots, the frames of a nominal duration, comprising:a demodulator for demodulating the received time division signal to produce a demodulated signal;a framing circuit operatively coupled to the demodulator to sequentially partition the demodulated signal into frames of the nominal duration;a time division control circuit operatively coupled to the framing circuit to extract time division control information from within the frames which indicates a certain time slot for real-time processing by the communication device;a time slot assignment circuit operatively coupled to the framing circuit and the time division control circuit to, based on a time slot indicated by the time division control information, dynamically assign a present time slot for real-time processing by the communication device and to, based on a different time slot indicated by the time division control information, dynamically re-assign a next time for real-time processing by the communication device;a real-time timing control circuit operatively coupled to the time slot assignment circuit to determine a recovered-data duration for producing recovered data, wherein the recovered-data duration will vary from the nominal duration during a next time slot re-assigned by the time slot assignment circuit; anda data decoder operatively coupled to the framing circuit and the real-time timing control circuit to decode the present time slot of a frame and produce recovered data real-time during the recovered-data duration and wherein, when the real-time timing control circuit varies the recovered-data duration from the nominal duration for a next time slot upon re-assignment, the decoder thereby performs time expansion or compression to produce recovered data.
