1. A method, comprising:
- broadcasting a feedback message in a downlink channel before an end of a selected frame of an uplink channel, the feedback message comprising information indicative of a data device that successfully sent a data reservation request by contention, minislot and slot assignment information of a voice device in a frame immediately subsequent to the selected frame, minislot and slot assignment information of a data device in the frame immediately subsequent to the selected frame, information responsive to the data reservation request, and a permission probability, the data device for utilizing information comprised in the feedback message in making a data reservation request in frames subsequent to the selected frame, the feedback message responsive to a first slot being assigned responsive to a voice reservation request in the selected frame, the uplink channel comprising a plurality of frames, each frame comprising a first selectable count of minislots and a second selectable count of slots, the voice reservation request contained in a first selected minislot of the selected frame of the uplink channel when a voice transmission is ready to be sent, the voice reservation request for causing an assignment of the first slot to the voice transmission in a frame that is subsequent to the selected frame, the data reservation request that is received contained in a second selected minislot of the selected frame when the second selected minislot is available in the selected frame and when data is ready to be sent, the data reservation request for causing an assignment of a slot to transmit data in another frame that is subsequent to the selected frame, the data reservation request for contending with other data reservation requests for the second selected minislot based on a contention algorithm, wherein the feedback message for changing a frame assignment initially used to transmit background noise of the voice transmission responsive to a determination to use a silence compression during a speech silence in the voice transmission, wherein the speech silence is detected via a voice activity detector.

Abstract
Certain exemplary embodiments provide a method for providing multiple access to a communication channel, the method comprising: sending a reservation request of a first type into a first selected minislot of a selected frame of an uplink channel when information of a first type is to be sent, the uplink channel having a plurality of frames, each frame having a first selectable number of minislots and a second selectable number of slots, the reservation request of the first type requesting an assignment of at least one slot for transmitting information of the first type in at least one frame that is subsequent to the selected frame.
