Abstract:
1. A method, comprising: scanning for at least one interfering frequency band in a geographical area of a first wireless communication system configured to operate in at least one first frequency band and a second wireless communication system configured to operate in at least one second frequency band, by a second apparatus operating in the second wireless communication system, wherein the at least one second frequency band is different from the at least one first frequency band; receiving at the second apparatus a signal from a first apparatus operating in the first wireless communication system indicating the at least one interfering frequency band that receives interference from at least one second frequency band of the second wireless communication system and encoding information of an acceptable interference level; decoding the acceptable interference level from the received signal; estimating interference based to the first apparatus on the signal; configuring the operation of the second apparatus in response to the estimated interference to the first apparatus not exceeding the acceptable interference level with a similar or reduced guard band between the at least one interfering frequency band and the at least one second frequency band of the second wireless communication system.
