Abstract: A system and method of assigning frequencies from a reuse group according to service type and subscriber location in a wireless communications network utilizing multiple reuse frequency groups for the assignment of transmission channels. Initially, a mobile station requests a transmission channel. A network element then receives the request and determines the data rate requirements of the mobile station for the level of service provided by the network to the mobile station. Concurrently, the signal strength from the mobile station to a serving base station subsystem is measured. The network element then assigns a frequency to the mobile station which belongs to a reuse frequency group that supports the data rate requirements at the signal strength measured.

Abstract: A system and method in a wireless communications system enables a preferred frequency hopping (FH) sequence to be determined and instituted in real-time. The average speed of mobile stations within a cell is determined or estimated using a variety of techniques. If the average speed is below a predetermined threshold, then a cyclic FH sequence is instituted to achieve superior frequency diversity and therefore combat small-scale fading dips. If the average speed is above a predetermined threshold, then a random FH sequence is instituted to achieve superior interference averaging and therefore combat co-channel interference. Delay timers and a hysteresis may also be used to enhance stability and to counteract short-term fluctuations. The measuring of the average speed and the comparing of the average speed to the threshold are periodically repeated.
