Abstract: Signalling uplink and downlink scheduling grants for a plurality of subframes in a time division duplex frame is addressed. In one aspect the allocated uplink subframes are divided into groups, so the number of groups equals the number of downlink subframes being allocated. Uplink grants for the groups are sent with the downlink grants, and for those groups that have more than one uplink subframe, the grant message also indicates which uplink subframes are included in that group. In another aspect there are two sets of grant messages, one for the uplink subframes and one for the downlink subframes. Each of the uplink grant messages is sent on a different uplink grant message, and there is a one-to-one correspondence between the uplink grant channel and the uplink subframe being scheduled by the grant. That correspondence may also be signalled with the grant messages.

Abstract translation: 针对时分双工帧中的多个子帧的信令上行链路和下行链路调度许可被寻址。 在一个方面，所分配的上行链路子帧被划分成组，因此组的数量等于被分配的下行链路子帧的数量。 发送组的上行链路授权与下行链路授权一起发送，并且对于具有多于一个上行链路子帧的那些组，授权消息还指示哪个上行链路子帧被包括在该组中。 在另一方面，存在两组授权消息，一组用于上行链路子帧，一组用于下行链路子帧。 每个上行链路许可消息在不同的上行链路许可消息上发送，并且上行链路授权信道和由授权调度的上行链路子帧之间存在一一对应关系。 也可以用授权消息来表示该对应关系。

Abstract: 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.

Abstract: A method, apparatus and computer program product are provided facilitating flexible time sharing among systems. A method and apparatus may generate a secondary component carrier transmission plan including planned on and off durations. The planned on durations correspond to a time period for an apparatus and devices to communicate via an unlicensed band of the secondary component carrier. The planned off durations correspond to a time interval in which the devices may deactivate from the unlicensed band or remain disconnected from the unlicensed band. The method and apparatus may also enable provision of the plan to the devices via a licensed band of a primary component carrier and detecting a medium of the unlicensed band prior to the expiration of the time period to determine whether the medium is available in order to decide whether to turn on transmissions to the unlicensed band after one of the planned off durations.

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。
