Abstract
An improvement to a spread-spectrum, code-division-multiple-access (CDMA) cellular system having multiple circuit-switched (CS) remote stations, multiple packet-switched (PS) remote stations and a base station per cell. The 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. The 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 are related by a relation of the CS-symbol rate and the PS-symbol rate to efficiently share system capacity.
