A dynamic capacity allocation spread spectrum CDMA communications system for overlaying, at least in part, geographically and in frequency a radio-relay system. A first receiver, located near the relay receiver of the radio-relay system, measures a first power level within the relay bandwidth of the radio-relay system. A second receiver, located near the relay receiver, measures a second power level outside the relay bandwidth of the radio-relay system. The first power level is compared to a predetermined threshold. A ratio signal is generated from the first power level and the second power level. When the first power level exceeds the predetermined threshold, the ratio signal is used to regulate the power level and dynamically allocate the capacity transmitted from each spread-spectrum-base station.

A method for dynamically allocating power and capacity of a spread spectrum system having at least one spread-spectrum-base station, with said spread spectrum system overlaying, at least in part, in frequency and in a same geographical area as a radio-relay system, said radio-relay system having at least one relay station within the geographical area, said radio-relay system having a signal with a radio-relay bandwidth, comprising the steps of: coupling, with a diplexer, the signal received at said relay station to said radio-relay system; measuring, at said radio-relay system, with a first receiver having a bandpass filter and with the first bandwidth overlapping the radio-relay bandwidth, a first power level within the radio-relay bandwidth of said radio-relay system; measuring, at said radio-relay system, with a second receiver having a bandpass filter with the second bandwidth not overlapping the radio-relay bandwidth, a second power level outside the radio-relay bandwidth of said radio-relay system; comparing the first power level to a predetermined threshold; generating a ratio signal from the first power level and the second power level; regulating, when the first power level exceeds the predetermined threshold, a power level transmitted from the at least one spread-spectrum-base station located within the geographical region in response to the ratio signal; and regulating, when the first power level exceeds the predetermined threshold, a number of user units accessing the at least one spread-spectrum-base station.
