Abstract: A method and apparatus are described for controlling the data rates for communications to and from a base station and a plurality of remote users. The usage of the communications resource whether the forward link resource (from base station to remote users) or reverse link resource (from remote users to base station) is measured. The measured usage value is compared against at least one predetermined threshold value and the data rates of communications or a subset of communications on said communications resource is modified in accordance with said comparisons.

Abstract: In a communication system in which direct sequence spread spectrum modulation techniques are used interference is generated in communications by remote stations since the communications share the same frequency spectrum. In order to increase system capacity the power level of the remote station transmitters are controlled by the local station. A setpoint is generated by the local station and compared with the remote station signal strength measured at the local station. The result of this comparison is used to generate power level adjustment commands which are sent to the remote station. The remote station is responsive to the power level adjustment commands for increasing or decreasing remote station transmitter power. In a spread spectrum communication system in which data is encoded at variable data rates, the local station determines the rate at which received data was encoded by the transmitting remote station. The data is decoded at each possible rate with error metrics generated that are representative of the quality of the data decoded at each rate. A rate decision algorithm is used to evaluate the error metrics and make a decision on the rate at which the data was transmitted. A pattern match of rate decisions is used to modify a setpoint so as to closely control the transmitting power of the remote station as a function of the quality of the received data.

Abstract: The cellular communication system includes a number of base stations through which a mobile unit communicates. The mobile unit maintains a list of active base stations with which it can communicate. One of the active stations is in communication with the mobile and uses this communication to measure the round-trip-delay between mobile and station. This delay is compared with a threshold and if this is exceeded, and the base station is a boundary station, then a hard hand-off is executed. The mobile can also monitor candidate base stations and if a triggering pilot signal is detected a hand-off can be triggered. Preferably the handoff can be between base stations controlled by different mobile switching centres.
