Abstract
Official abstract text for this publication.
An Orthogonal Frequency Division Multiplexing communication system is provided that schedules a transmission of uplink sounding signals or channel quality feedback signals in sounding intervals, or sounding zones, that are outside of the sub-frames, thereby preserving sub-frame capacity for other overhead and data transmissions.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for providing channel sounding in an Orthogonal Frequency Division Multiplexing communication system, the method comprising: instructing, by a scheduler of a network controller, a user equipment to transmit a sounding signal, a channel quality feedback signal, or both the sounding signal and the channel quality feedback signal during a sounding interval within a Transmit Transition Gap, wherein the sounding interval is not within any downlink sub-fr…
