Abstract:
1. A method of allocating signal quality feedback slots, comprising: allocating, by an access node of a communication system, a signal quality feedback slot to a wireless device in one out of every E″ channel quality indicator channel (CQICH) frames, wherein 0≦n≦N increasing, by the access node, n when an indicator of RF conditions received in at least one signal quality feedback slot satisfies a first criteria; decreasing, by the access node, n to a minimum value, when a number of retry requests from the wireless device satisfies a retry criteria; maintaining, by the access node, a count of the number of consecutive frames the wireless device is allocated a slot; and resetting the count, when the indicator of RF conditions received in at least one signal quality feedback slot satisfies a second criteria, wherein the first criteria includes the count satisfying a third criteria.
