摘要： Providing a sleep mode for network nodes in a wireless communication network. In sleep mode the node broadcasts either zero signals or a subset of normal operating mode signals in order to save power. An uplink signal from user equipment requesting service may contain an wakeup signal to restore normal operation. The uplink signal may also be used for uplink synchronization or random access. A downlink confirmation signal confirms that the node is prepared to deliver normal service. In a configuration of small cells communicatively associated with a macro network node, a method for providing a sleep mode for the small cells. The macro cell requests a user equipment (UE) to send a wake-up signal to which responding small cells answer with a wake-up detected signal. The macro node signals small cells to transmit pilot signals that are measured by the UE to determine which small cell services the UE.

摘要： At least one preamble is dedicated for interference probing. An aggressor access node (macro eNB) sends a command to a user equipment (UE) to transmit the dedicated preamble on a physical random access channel (PRACH). A victim access node (pico eNB) detects the transmitted preamble, and if this UE is the source of uplink interference to the victim access node it informs that to the macro access node which may then use interference coordination and interference cancellation to mitigate further uplink interference. In some embodiments the victim access node decides what is the transmit power for the UE to use for the dedicated preamble on the PRACH, and informs it to the macro access node which instructs the UE of the transmit power to use. In one example embodiment the victim access node calculates an offset from SRS/PUSCH transit power and informs the macro access node of the offset.

摘要： 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.

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) simultaneus 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。
