Abstract:
1. A method of avoiding adjacent channel interference and reducing disconnections caused thereby, during communication between a mobile device ( 102 ) and a base station ( 202 ) that communicate via a communication channel in a wireless communication network, comprising the steps of: measuring ( filtering ( remeasuring ( estimating ( requesting ( wherein the steps of measuring ( 302 ), filtering ( 304 ), remeasuring ( 306 ), and estimating ( 308 ) are performed while the mobile device is capable of using the communication channel for receiving and transmitting data, wherein both the communication channel and the alternative communication channel are for communication between the mobile device ( 102 ) and the base station ( 202 ); and wherein the power ratio is substantially determined by adjacent channel power divided by communication channel power, the communication channel power being substantially given by the magnitude of the filtered signal, and the adjacent channel power being calculated as a function of both the magnitude of the filtered signal and the magnitude of the received signal.
