PROBLEM TO BE SOLVED: To provide a hybrid of contention-free communications and contention communications for a shared communications medium. SOLUTION: Contention communications often require a station to wait an inordinate amount of time before the station is able to transmit its data successfully. In many applications, an extended delay is not acceptable. Contention-free communications in a contention period allows a hybrid coordinator (HC) to schedule contention-free access to a communications medium so that extended delays may be eliminated, and to coordinate contention access to the medium so that better throughput and delay performance is achieved. A method for creating contention-free communications within a contention communications period is presented, along with adaptive algorithms for contention access during the same contention period. In one embodiment of this invention, the method provides contention-free transmission during a contention period in a shared communications medium comprising capturing the shared communications medium (660), permitting a recipient to transmit, and recapturing the shared communications medium after the recipient transmits. |
