Abstract: Mechanisms for controlling communications conducted in multiple frequency bands so as to decrease an interference level between the communications. When an interference situation caused between an UL communication performed on at least one frequency band and a DL communication performed on another frequency band is determined, a partial denial processing is conducted so as to deactivate a dedicated part of resource blocks used for the first communication on the at least one frequency band of the first communication in the case of an interference situation being determined. The first communication is then continued in parallel to the second communication, on the basis of resources different from the dedicated part of resource blocks deactivated in the partial denial processing.

Abstract: There is provided a mechanism for controlling communications conducted in multiple frequency bands so as to decrease an interference level between the communications. When an interference situation caused between a first set UL communications performed on at least two different frequency bands and a DL communication performed on another frequency band is determined, a frequency carrier deactivation processing is conducted so as to deactivate either one of carriers of the at least two frequency bands of the set of UL communications. The deactivation processing comprises for example an autonomous denial on the UE side or an interference reporting with deactivation on the eNB side.
