Abstract
A method for radio resource allocation based on planned priority ordering to realize the maximum carrier to interference ratio (C/I) in a cellular system that employs frequency reuse. Reuse of co-channel resources is progressively increased as traffic load increases based on the available spectrum. By using this method, interference rejection at light loading can approach that obtainable by using a low reuse factor. When applied to a wireless packet network, this method allows each resource to carry highest throughput according to the traffic demand and available bandwidth, while making more resources available to carry additional traffic when system loading is increased.
Claims1
A method for radio resource allocation in a wireless cellular system that employs frequency reuse, said method comprising the steps of:
- measuring cellular traffic load in said system as a function of available spectrum;
- reusing co-channel resources within said system;
- and
- progressively increasing said co-channel resource reuse as said traffic load increases in accordance with a predetermined priority in order to maximum the carrier to interference ratio.
