EFFICIENT SHARING OF CAPACITY BY REMOTE STATIONS USING CIRCUIT SWITCHING AND PACKET SWITCHING

摘要

An improvement to a spread-spread-spectrum, code-division-multiple-access (CDMA) cellular system having a plurality of base stations (110, 120, 130, 140, 150, 160, 170, 180, 190,) with one base station per cell. Each base station, for example, the first base station, has multiple remote stations, and the first base station has the multiplicity of remote stations (11, 112, 113, 114). A remote station may be either a circuit-switched (CS) remote station or a packet-switched (PS) remote station. A remote station also can be a combination, CS-remote station and a PS-remote station. Each CS-remote station transmits a spread-spectrum CDMA signal, with a chip rate of fc, with a CS-symbol rate of fb, and with a power level Pcs. Each PS-remote station transmits a spread-spectrum CDMA signal with the chip rate of fc, PS-symbol rate fp, and with a power level Pps. The power level Pps from the PS-remote station and the power level Pcs from the CS-remote station and the power level Pcs from the CS-remote station are related by a relation of the CS-symbol rate and the PS-symbol rate to efficiently share system capacity.
