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.

Abstract: Methods, apparatus and computer program products configure a sounding reference signal (SRS) for a segment carrier that serves as a contiguous bandwidth extension of a component carrier, such as a component carrier that is backwards compatible with prior releases of a mobile terminal. In the context of a mobile terminal, the method receives a triggering message that identifies respective configurations of the SRS for the component carrier and the associated segment carrier. The configuration of the SRS for the component carrier is different than the configuration of the SRS for the segment carrier. The method also causes the SRS to be transmitted in accordance with the respective configurations identified by the triggering message via uplink subframes of the component carrier and the segment carrier.

Abstract: A user equipment UE is configured with an integer value N which defines an effective data rate. The network sends to the UE a grant for uplink transmissions that comprises a resource indication field that allocates N channels each having a same predetermined uplink format and payload capacity. The UE sends N bit sequences on the respective N channels, each bit sequence comprising data and the same predetermined uplink format. In various embodiments: the network specifically configures the UE to receive the predetermined format of the grant; the grant may have an indicator whether the channels are for new data and for the MCS to use; the N channels may be in a same or in adjacent sub frames regardless of the value of N; and there is one MAC header for all the N channels which the network reads as a single MAC PDU.

Abstract: A method, system, and computer program product that provides a two-index system for clusters of small cells in a wireless network. A first index is employed for access to and identification of a serving cell within a cluster of small cells. A second index indicates a group of small cells for determining mobility control. The first index may be derived from primary/secondary synchronization signals, or from frequency/time division multiplex signal position. The second index may be indicated in system/master information block signals or predefined as a plurality of small cells identified by the first index for each cell. Determination of physical cell identification is aided by providing a plurality of primary/secondary synchronization (PSS/SSS) signal alternating configurations with indicator, wherein a maximum number of configurations is predefined. Signaling the PSS/SSS configurations by one of broadcast or dedicated signaling, said signaling indicating whether each configuration is one of periodic or aperiodic alternation.
