Abstract: Methods of providing power overload control in a communication system having a least one base station serving one or more users of at least one cell are described which may avoid an overload condition in the system. In one aspect, a target signal-to-interference ratio (SIRtarget) may be controlled for inner loop power control implemented by the base station, so as to maintain the loading of the communication system below an overload condition. In another aspect, a target block error rate (BLERtarget) may be controlled for outer loop power control implemented by the base station, so as to maintain the loading of communication system below an overload condition.

Abstract: A radio resource method and apparatus involves allocating transmission channels to and from a node (26) based on the system load requirement. The load requirement is determined from the quality of service requirement which, in turn, is assessed from the data rate, the bit energy to noise power ratio and the signal classification produced by a converter and sorter (38) in response to signal transmission requests. A maximum load generator (40) delivers the maximum load from these parameters. A core calculator and assignor (42) performs a predetermined algorithm on the outputs of the converter and sorter (38) and the maximum load generator (40) and in response thereto controls a channel selector (30) which selects the channels to and from node (26).
