Abstract
An Orthogonal Frequency Division Multiplexing communication system is provided that triggers a transmission of an uplink sounding signal by use of a Downlink Control Information (DCI) message. In various embodiments of the invention, the DCI message may be used to individually trigger an uplink sounding signal by a single user equipment or may be used to trigger an uplink sounding signal by a group of users equipment.
