ABSTRACT:
Information systems, detectors, and methods for a communication link, such as the downlink of a cellular telephone system, reduce the problem of uplink transmit power peaks when the uplink is out of synchronization (OoS). One method of indicating that a first link to a communication node is OoS includes the step of including an OoS signal in signals that are sent by the node on a second link. The OoS signal includes at least one data bit transmitted by the node that indicates that the first link is synchronized or OoS. A method of determining that a first link to a communication node is OoS includes the step of detecting an OoS signal in signals that are sent by the node on a second link. The OoS signal includes at least one data bit that indicates that the first link is synchronized or OoS.
