Abstract

A radio access method for facilitating communication between at least one first station and a plurality of second stations is disclosed. First, each signal intended for transmission is buffered at a first station. The signals are then divided into equal length segments. The signal segments intended for a particular one of the second stations is transmitted using a corresponding time slot (Slot 1) in a regularly repeating time multiplex frame. The signal segments transmitted by the first station are received at at least one of the second stations and the signal segments are assembled from successive corresponding time slots (Slot 1) to reconstruct said intended signal. A transmit frequency channel (F1) uniquely associated with the corresponding receive time slot (Slot 1) is determined at the second station. Finally, a signal intended for transmission to the first station is buffered in the second station and compressed for transmission using the transmit frequency channel (F1) during substantially the entire time period that the second station is not receiving.
