Abstract:
1. Apparatus for use in a wireless communications base station comprising: A receiver for monitoring at least one prescribed portion of a control channel resource of an incoming control channel to detect an incoming unlink traffic channel request from at least one mobile unit to which said at least one prescribed portion of said control channel resource is exclusively dedicated, said traffic channel request being periodically repeatedly transmitted by said at least one mobile unit; a detector for determining whether any uplink traffic channel requests have been received and, when an uplink traffic channel request has been detected, assigning a traffic channel to said at least one requesting mobile unit; a transmitter responsive to a determination that at least one request has been received for transmitting a request response message including said traffic channel assignment to said at least one requesting mobile unit; wherein said at least one mobile unit and said base station a priori know the location of said prescribed portion of said control channel resource in said control channel, wherein control header information that indicates at least a structure of said control message is not required to be transmitted with said uplink traffic channel requests; and a utilization apparatus adapted to utilize said received traffic channel request to determine the true value of said received traffic channel request by subtracting an amount of traffic channel resource that has been assigned to said mobile unit that is not known to the mobile unit as being assigned at the time said mobile unit transmitted an uplink traffic channel request from an amount of said traffic channel resource requested in said transmitted uplink traffic channel request.
