wireless communication system, wireless kommunikationseinheit and practices to reduce the impact of interference - ranging

摘要

A wireless communication system (200) comprises at least one wireless serving communication unit (222), e.g. base transceiver or transceiver station, serving a plurality of remote units (212-216) with a communication resource (218-220). The at least one wireless serving communication unit (222) detects non-availability of an one or more inbound communication resource(s) owing to interference or jamming and transmits a broadcast message on an outbound communication resource indicating a non-availability of the one or more inbound communication resource(s). A communication unit and method of communication are also provided. Thus, by using a broadcast message of an uplink channel's non-availability, the impact of a third party transmitting a jamming /interfering signal to interfere with inbound signals to the serving unit is reduced.
