Abstract: A network access node identifies a component carrier within an unlicensed radio spectrum, determines whether or not to configure the component carrier for use as a secondary component carrier, and based on the determining configures the component carrier for use as a secondary component carrier companion to a primary component carrier within a licensed radio spectrum, In various non-limiting embodiments the network node senses the component carrier within the unlicensed radio spectrum, and as more data is needed to make the determination employs a mobile device to also sense and further to measure the component carrier within the unlicensed radio spectrum. Specific procedures are detailed for both the network node and the mobile device.

Abstract: A user equipment UE determines at least one first set SI of physical resource blocks PRBs, and detects downlink signaling within search spaces of set(s) SI. Through that downlink signaling the UE obtains a configuration for a downlink control channel, and that configuration indicates at least one second set S2 of PRBs and at least one search space specific for the UE which lies within S2. The UE utilizes the obtained configuration to monitor at least some of the search spaces of SI and the at least one search space specific for the UE of S2 for further downlink control signaling. Multiple implementations are detailed for how the UE gets SI. This invention is particularly useful for a configurable ePDCCH region in a stand-alone carrier where the UE is not able to get the new configuration from some other carrier such as a PCell whose configuration does not change.

Abstract: An aggressor access node in a heterogeneous network sends to a victim access node a pattern of transmit power for designated low-interference subframes (e.g., LP-ABSs). Utilizing feedback information collected from the victim node which quantizes interference seen by user equipments (UEs) which are allocated at least some of those subframes, the aggressor node selects whether and how much to adjust transmit power for subsequent such subframes, then sends to the victim node a pattern of the adjusted transmit power for those subsequent subframes (e.g., an enhancement to relative narrowband transmit power RNTP). The victim node sends to UEs the pattern of transmit power and respective resource allocations in those designated low-interference subframes; then derives interference level per UE in those subframes based on channel quality indications received from the respective UEs; and sends to the aggressor access node feedback information which quantizes the derived interference levels.

Abstract: 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.
