ABSTRACT:
A method of balancing availability of uplink (102) and downlink (101) frequency bandwidths includes determining a demand level for use of downlink (101) frequency bandwidth, and occupying artificially a portion of uplink (102) frequency bandwidth based on the demand level to balance the availability of the uplink (102) and downlink (101) frequency bandwidths. Occupying artificially a portion of uplink (102) frequency bandwidth includes limiting access to a plurality of uplink time slots in uplink (102) communication. Failure to receive a demand for originating a call on uplink (102) communication or a demand by at least one of a plurality of mobile stations to terminate its uplink (102) communication triggers occupying artificially a portion of uplink (102) frequency bandwidth.
