Abstract:
1. A method for allocating resources in a communication system having a plurality of base stations each serving multiple user stations, the method comprising: receiving, at a first base station, service requests from a plurality of user stations; determining, at a first base station, interference generated by other base stations; dynamically allocating resources at the first base station including assigning a transmission rate for transmission of information between the first base station and each user station independently of allocation of resources performed by other base stations, based on a set of criteria including a set of requirements associated with each service request and the determined interference generated by other base stations in the communication system, wherein the transmission rate assigned to each user station is determined to optimize a sum of all transmission rates assigned by the first base station to the plurality of user stations based on the set of requirements associated with each service request and wherein higher transmission rates are assigned to user stations which are relatively closer to the first base station; transmitting rate assignment information from the first base station to the plurality of user stations; and iteratively modifying rate assignments based on the received service requests and the determined interference from other base stations.
