Abstract
Methods and apparatus for improving the performance of a conventional cellular telephone system. In a conventional system, a base station (12) located in a cell (10) both sends and receives signals to and from handheld phones (14). In one embodiment, the present invention employs a relay transceiver (18) located in the cell (10) to relay signals (20) from handheld phones (14) to the a base station (12). The handheld (14) still receives signals (16) directly from the base station (12), but the return signal (22) back to the base station (12) is accomplished through the relay transceiver (18).
