Abstract: A MIMO-capable base station allocates a maximum transmission power budget to each of its antennas. For serving each of one or more MIMO and non-MIMO users, one or more carriers are allocated. For each carrier, information about an amount of allocated MIMO and non-MIMO user resources associated with the carrier is used to derive coefficients. Each coefficient corresponds to a unique one of the antennas, and represents a proportion of a maximum power budget for the carrier. For each carrier, the coefficients and the maximum transmission power budget for the carrier are used to derive a maximum transmission power budget for each of the antennas. For each antenna, a total maximum transmission power budget for the antenna is derived by combining the derived maximum transmission power budgets of the carriers transmitted on the antenna. The total maximum power budget of the antenna should not exceed a limit for the antenna.

Abstract: The present invention provides, inter alia, a method of operation of a radio base station in a wireless telecommunications system, in which system information is transmitted on a broadcast control channel. The method comprises the steps of transmitting the broadcast control channel continuously on a first carrier; and also transmitting the broadcast control channel non-continuously and periodically at regular intervals. This prevents or at least minimizes, for example, MBMS data loss when a UE with a single receiver listens to a dedicated MBMS carrier.

Abstract: When a high SIR can be achieved for downlink data transmission, for example in a MIMO system, or when higher order modulation, such as 64 QAM, can be used, it is desired to measure the instantaneous downlink channel quality indicator (CQI), and report the measured CQI to the network using the same number of bits as when a lower SIR can be achieved. In order to do this, a true CQI is derived based upon at least one network controlled parameter and a measured channel quality parameter; and the true CQI value is scaled to a new CQI value such that the new CQI will fall within a specified range of CQI values; so that the new CQI achieved by scaling the derived CQI value can be reported with every CQI value over the entire reporting range requiring the same number of bits.

Abstract translation: 例如在MIMO系统中，当可以实现下行链路数据传输的高SIR时，或者当可以使用诸如64QAM的高阶调制时，希望测量瞬时下行链路信道质量指示符（CQI），并且 使用与可以实现较低的SIR相同数量的比特来将所测量的CQI报告给网络。 为了做到这一点，基于至少一个网络控制参数和测量的信道质量参数导出真实的CQI; 并且将真实CQI值缩放到新的CQI值，使得新的CQI将落入CQI值的指定范围内; 使得通过缩放导出的CQI值实现的新CQI可以在需要相同数量的比特的整个报告范围上的每个CQI值被报告。

Abstract: The present invention relates to cellular system and especially to handover between cells on different frequency carriers in an OFDM system or between cells in 2 systems adopting different radio access technologies (RAT), at least one of them being OFDM technology. A problem is the intra-cell interference impact on the quality a connected mode terminal measures in the own cell and in neighbor cells. This is a problem for cells based on OFDM technology, because intra-cell interference has no impact as compared to the inter-cell interference on the quality provided by the cell to a connected mode terminal, whereas in UTRA the intra-cell and inter-cell interference have the same impact on the quality provided. The solution to the problem is based on the insight that for cells that are located on the same site, the eNode B possess information on the power transmitted on the respective frequency carrier, and can adjust the quality as reported from the terminal on co-located OFDM cells. The adjusted quality measure enables an improved evaluation of the quality of co-located cells, for a potential handover. The invention also relates to embodiments on a 2-step handover, wherein handover to inter-frequency, or inter-RAT cell on another site is made as a handover to co-located inter-frequency/inter-RAT cell and a handover to an intra-frequency cell located at the other site.

Abstract translation: 本发明涉及蜂窝系统，特别涉及在OFDM系统中的不同频率载波上的小区之间或采用不同无线电接入技术（RAT）的两个系统中的小区之间的切换，其中至少一个是OFDM技术。 问题是小区内干扰对连接模式终端在自身小区和邻居小区中的质量的影响。 这是基于OFDM技术的小区的问题，因为小区间干扰与小区向连接模式终端提供的质量的小区间干扰没有影响，而在UTRA中，小区内和小区间干扰 细胞干扰对提供的质量有相同的影响。 该问题的解决方案是基于对于位于同一站点上的小区的见解，eNode B具有关于在相应频率载波上传输的功率的信息，并且可以调整从共同终端上报告的质量 OFDM小区。 经过调整的质量测量可以改善对位置单元质量的评估，以实现潜在的切换。 本发明还涉及两步切换的实施例，其中将另一站点上的跨频率或RAT间小区的切换设置为切换到共同定位的频间/ RAT间小区，并切换到 位于另一个站点的频率内单元。

Abstract: A home base station (HBS) (104, 801) performs radio channel measurements to detect one or more user equipments (UEs) (107) not served by the HBS which may be in a potentially interfering environment caused at least in part by the HBS. A database (812) of historical channel data (channel fingerprinting) of the HBS coverage area is used to predict the channel conditions and expected interference signal power seen by the detected UE(s). Based on a combination of the radio measurements (813) and historical channel data, the HBS can accurately and adaptively reduce its transmit power to a level that reduces or eliminates interference with the detected UE(s), while also not significantly degrading communication quality between other UEs served by the HBS.

Abstract translation: 家庭基站（HBS）（104,801）执行无线电信道测量以检测不由HBS服务的一个或多个用户设备（107），所述HBS可能至少部分地由HBS引起潜在的干扰环境 。 使用HBS覆盖区域的历史信道数据（信道指纹）的数据库（812）来预测检测到的UE看到的信道状况和预期的干扰信号功率。 基于无线电测量（813）和历史信道数据的组合，HBS可以将其发射功率精确和自适应地降低到降低或消除对所检测到的UE的干扰的水平，同时也不会显着降低 由HBS服务的其他UE。
