摘要： The initialization of the CoMP Resource Management Set for a given mobile terminal is based, at least in part, on an estimation of the mobile terminal's geographical location, which can be estimated using network positioning of the mobile terminal. One example method begins with the acquisition (410) by a network node of a geographical position estimate for the mobile terminal of interest. The network node then selects (420) a set of one or more CSI-RS resources for measurement by the mobile terminal, based on the estimated geographical position of the mobile terminal. Finally, the network node configures the mobile terminal to measure the selected CSI-RS resources by sending (430) control information identifying the set to the mobile terminal.

摘要： The object of the present invention is to achieve a solution for handling the increased PAPR that is introduced by the FD and/or TD multi-antenna processing. This is achieved by isolating the PAPR increase to one, or a few antennas, that are matched with more powerful PAs, whereas the remaining antennas may use simpler/smaller PAs amplifying signals with smaller PAPRs.

摘要： Frequency-selective phase shifts are applied to signals transmitted from multiple transmission points involved in a coordinated (joint) transmission to a given UE. An eNodeB or other network node controlling the joint transmission artificially induces frequency selectivity between signals received by the UE in joint transmission from different transmission points, so as to ensure an even balance between constructive and destructive combination over frequency. By applying frequency-selective phase shifts (e.g., pseudo-random phase shifts) to the different transmission points that perform joint transmission, the signals from the different transmission points are forced to combine at the UE in a non-coherent manner. As a result, uncertainty in how the signals combine is drastically reduced, since it can be expected that the signals will always combine incoherently. The reduced uncertainty translates to reduced back-off offset in the link adaptation, and thus in an increased throughput.

摘要： Some of the example embodiments presented herein are directed towards an eNodeB (401), and corresponding method therein, for providing data transmission in a multiple antenna system. The eNodeB (401) may be configured to receive a plurality of signal quality assessments and a CSI report from a user equipment. Based on the received data the eNodeB (401) may determine a received power difference between the received data.

摘要： A system and method to instruct a User Equipment (UE) how Uplink Control Information (UCI) on a Physical Uplink Shared Channel (PUSCH) should be transmitted with carrier aggregation. A semi-static signaling of a UCI mapping bit (via a Radio Resource Control (RRC) parameter) is used by a base station such as an eNodeB to require the UE to transmit UCI using one of two pre-determined UCI transmission modes. The bit can be decided by the base station, considering, for example, the available bandwidth or quality of different Uplink Component Carriers (UL CCs) associated with the UE. This network-based solution allows the network to either configure a general rule of UCI transmission by the UE or to enforce the UCI transmission on the Uplink Primary cell (UL Pcell). Because of the rules governing abstracts, this abstract should not be used to construe the claims.
摘要翻译： 指示用户设备（UE）如何应用载波聚合来发送物理上行链路共享信道（PUSCH）上的上行链路控制信息（UCI）的系统和方法。 UCI映射比特（通过无线资源控制（RRC）参数）的半静态信令由诸如eNodeB的基站用于要求UE使用两种预定的UCI传输模式之一来发送UCI。 考虑到例如与UE相关联的不同上行链路分量载波（UL CC）的可用带宽或质量，该比特可以由基站决定。 该基于网络的解决方案允许网络配置UE的UCI传输的一般规则或者在Uplink Primary小区（UL Pcell）上实施UCI传输。 由于管理摘要的规则，本摘要不应用于解释索赔。
