摘要： There is proposed a mechanism for controlling communications conducted in multiple frequency bands, in particular for controlling interference caused by intermodulation distortion. When the UE obtains information that an interference caused by an intermodulation distortion produced by a set of first communications performed on at least a first and a second frequency and a second communication performed on a third frequency is present, an indication to the eNB for indicating that an interference situation caused by intermodulation distortion exists. The eNB receiving this indication is enabled to acquire parameters related to the interference situation caused by the intermodulation distortion, and to control, on the basis of the acquired parameters, a communication with the UE by changing communication properties for reducing the interference caused by intermodulation distortion.

摘要： A low noise amplifier for radio frequency integrated circuits having an adaptive input and operating mode selection. The low noise amplifier comprises two inputs which can be operated in different configurations. The operating mode may be chosen in such way that the inputs are used respectively one at the time for single-ended configuration or both inputs are used for differential configuration. Additionally, in single-ended operation, inputs can be matched to different frequencies. The information regarding the operating mode is obtained from an external component. The operating mode to be used may be determined when the device using a particular radio frequency integrated circuit is designed or it can be determined dynamically by the device using the radio frequency integrated circuit.
