Interference measurements in a wireless communications system

Interference Measurements in a Wireless Communications SystemA method and a transmitting unit for performing an interference measurement in a multiple access wireless communications system utilizing a carrier sensing technique is described. In accordance with the carrier sensing technique, it is monitored during a sensing period (Tmin) if a carrier is idle. A continuous or quasi-continuous interference measurement is performed on the carrier during a measurement period (TM) which is typically longer than the sensing period (Tmin). While performing the interference measurement, pulses are transmitted on the carrier such that an interval between the end of a pulse and the beginning of the next pulse is typically shorter than the sensing period (Tmin). The interference measurements preferably relate to detection of interference from radar signals or radar like signals.
