Abstract

A system for allocating communication resources in a communication system where only a single frequency pair may be available for use by many users. A system wherein a resource controller transmits control information on a resource to many potential users without disrupting use of the resource by a primary user.

Claims

1. A resource allocation system for providing access to a communication resource, such resource allocation system comprising;

A. a plurality of communication groups each comprising a plurality of communication units, each communication unit having a transmitter and a receiver;

B. at least one communication group of the plurality of communication groups having a requesting communication unit;

C. a resource controller;

D. means operably coupled to the resource controller for selectively enabling the at least one communication group, allowing the requesting communication unit of the at least one communication group to transmit a resource request to the resource controller on the communication resource;

E. memory means within the resource controller for maintaining a request queue for requesting communication units;

F. means for allocating at least a portion of the communication resource to a first requesting communication unit in the request queue;

G. means for disabling the transmitters of communication units of the plurality of communication groups, exclusive of the first requesting communication unit, upon allocation of the communication resource; and

H. means for transmitting a request queue position to the at least one requesting communication unit over at least part of the allocated communication resource.

2. In a resource allocation system providing access to a communication resource by a plurality of communication groups, each with a plurality communication units, each communication unit having a transmitter and a receiver, a method of allocating the communication resource to communication units requesting access, the method comprising the steps of;

A. sequentially enabling the plurality of communication groups to transmit requests to a resource controller;

B. receiving a resource request from at least one requesting communication unit;

C. entering the at least one communication unit into a request queue;

D. allocating at least a portion of the communication resource to a first requesting communication unit in the request queue;

E. disabling the transmitters on the plurality of communication groups, exclusive of the first requesting communication unit; and

F. transmitting a request queue position to the at least one requesting communication unit over at least part of the allocated communication resource.
