Abstract:
A communication system (10) has at least one communication resource controller (28) for allocating a limited number of communication resources among a plurality of communication units. The communication resource controller monitors the communication resources and maintains a data library of the level and duration of any interference of the communication resources. The communication units (20 and 22) are constructed and arranged to communicate information on any of the communication resources. Any one of the plurality of communication units can initiate access to a communication resource by transmitting a request therefor. In response to a proper request, the communication resource controller (28) assigns a communication resource to the communication units in accordance with the data retrieved from the interference data library.
