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.

Abstract: The present application relates generally to use of radio resources in a radio access network (RAN) and, in more specific, Full-Duplex (FD) transmission on the same carrier. Due to the mobility of the UEs or the non-optimal grouping, two UEs belonging to different groups may be close to each other while performing transmission and cause serious transmission interferences to 5 each other. This is one of the problems which a method in accordance with the invention aims to solve. When the performing the method a RAN triggers a UE to measure 601 first interferences originated from a first group of UEs. Then the RAN triggers the same UE to measure 602 second interferences originated from a second group of the UEs. Finally, the RAN places 603 the UE into the first group, if the first interferences are higher than the second interferences. The both 10 groups of the UEs are composed of such user equipments which share a group-specific transmission pattern. Uplink and downlink resources of the RAN are scheduled according to a time-division to the UEs, so that simultaneous transmissions are allowed only for such user equipments that belong to different groups. Advantages of the invention are the following: 1) simultaneous transmission and reception is supported in a RAN and in a UE which is either a FD 15 UE or a HD UE, 2) different kinds of interferences are efficiently reduced, and 3) the interferences are measured in a way that saves power.

Abstract translation: 本申请一般涉及无线电接入网络（RAN）中的无线电资源的使用，并且更具体地涉及同一载波上的全双工（FD）传输。 由于UE的移动性或非最佳分组，属于不同组的两个UE在执行传输时可能彼此靠近，并导致彼此之间的严重传输干扰。 这是根据本发明的方法旨在解决的问题之一。 当执行该方法时，RAN触发UE测量从第一组UE发起的601个第一干扰。 然后，RAN触发相同的UE来测量源自第二组UE的602个第二干扰。 最后，如果第一干扰高于第二干扰，RAN将UE置于第一组中。 这两个UE组都由具有组特定传输模式的这种用户设备组成。 根据对UE的时分，调度RAN的上行链路和下行链路资源，使得仅对属于不同组的用户设备允许同时传输。 本发明的优点如下：1）在RAN和作为FD 15 UE或HD UE的UE中支持同时发送和接收，2）有效地减少不同种类的干扰，3）干扰 以节省电力的方式进行测量。

Abstract: There is provided a mechanism for allocating communication resources of a cellular communication network to a D2D communication. After an eNB has configured a number of resource pools indicating a set of resources usable in the D2D communication, D2D clusters which share a same resource pool are enabled to obtain resources for their respective D2D communication. By detecting the current resource utilization state in the allocated resource pool by measurement on the UE side, it is decided whether suitable resources are available or not. An overload situation is signalled to the eNB if no suitable resource can be detected.

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.

A method is provided that includes determining DL subframes that are included in a DL association set for each of a plurality of component carriers.

Abstract: The invention allows coordinating transmissions and receptions for over-the-air communication between uncoordinated base stations of an OFDM based cellular radio network. A radio resource dedicated for OTAC between uncoordinated base stations of an OFDM based cellular radio network is divided into subchannels. Deployment information of the uncoordinated base stations is obtained at a mobility management unit. Transmission allocation information is determined at the mobility management unit based on the obtained deployment information, the transmission allocation information comprising for each of the uncoordinated base stations their respective at least one symbol in said subframe of said dedicated radio resource and their respective at least one subchannel for use in their respective over-the-air communication transmissions, such that simultaneous over-the-air communication transmissions between an uncoordinated base station and its target uncoordinated base station are prevented. To the uncoordinated base stations are transmitted their respective determined transmission allocation information.

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.
