摘要： 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.

摘要： There is provided a mechanism for controlling communications conducted via different frequency bands or communication spectrums. When a communication via a first communication path, for example an unlicensed or white space communication spectrum, is to be established, e.g. for offloading traffic from a second communication path, for example a licensed cellular communication spectrum, a preamble transmission command is generated and transmitted from a communication network control element, such as an eNB, via the second communication path to a communication element, such as a UE. By means of the preamble transmission command, the transmission of a preamble signal by the receiving communication element on the first communication path with predetermined communication resources is triggered. Based on a receipt or non-receipt of the preamble signal via the first communication path, the communication network control element is able to determine that the communication element can establish a connection on the first communication path, for example the unlicensed or white space communication spectrum.

摘要： 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.

摘要： There is proposed a mechanism for controlling and conducting a discovery procedure of small cells or secondary ceils located in a macro cell or primary cell. The discovery procedure is based on a discovery signal communicated via PDCH and based on a positioning reference signal (PRS). For configuring the signaling of the discovery signal, frequency domain multiplexing for splitting resources of the PRS in the frequency domain for increasing capacity, and/or usage of reserved communication resources for the signaling of the discovery signal are employed. Assistance information is provided to the UE for supporting the discovery of small cells.
