ABSTRACT:
A method is performed in a receiver including a number of modules. The method includes receiving information in a reception frequency band. Responsive to a notification from a transmitter of a transmission in a predetermined transmission frequency band, at least one countermeasure is performed by at least one of the modules. The at least one countermeasure is predetermined to reduce an effect of interference caused by transmission on reception of the information in the reception frequency band. Countermeasures include freezing an automatic gain control loop, freezing a synchronization loop, discarding channel estimation data, and blanking received information. Transmission power and transmission mode are also used to determine whether and how many countermeasures are used. Additionally, handover is improved by waiting until transmission is complete to determine receiver signal strength of signals from potential transmitters for handover.
