摘要： To find a D2D channel, by example a shared channel for offload traffic from an allocated D2D channel, a cellular network access node sends a configuration message with parameters (e.g., sensing time, frequency band, sensing mechanism, cyclic shift) for a D2D device to sense spectrum. From results of this spectrum sensing is decided whether to utilize a frequency band, sensed according to the parameters, for D2D communications. In an embodiment the network selects a subframe configuration to set the sensing time, in which different subframe configurations have different-length guard periods which is the sensing time. In embodiments a first sensing is within a guard period and represents coarse sensing results and if those are not sufficient the network configures a longer sensing time (e.g., spanning multiple subframes) for finer sensing results. The network or alternatively the D2D device decides whether to use the sensed frequency band for offload traffic.
摘要翻译：为了找到D2D信道，例如用于从分配的D2D信道的卸载业务的共享信道，蜂窝网络接入节点向D2D设备发送具有参数（例如，感测时间，频带，感测机制，循环移位）的配置消息感光谱。根据该频谱感测的结果，决定是否利用根据参数感测的D2D通信的频带。在一个实施例中，网络选择子帧配置来设置感测时间，其中不同的子帧配置具有作为感测时间的不同长度的保护周期。在实施例中，第一感测在保护周期内并且表示粗略感测结果，并且如果这些感测结果不够，则网络配置更长的感测时间（例如，跨越多个子帧）以获得更精细的感测结果。网络或备选地，D2D设备决定是否使用所感测的频带来进行卸载业务。

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.
摘要翻译：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，并且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。
