摘要

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 (T_min) if a carrier is idle. A continuous or quasi-continuous interference measurement is performed on the carrier during a measurement period (T_M) which is typically longer than the sensing period (T_min). 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 (T_min). The interference measurements preferably relate to detection of interference from radar signals or radar like signals.
