摘要： 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 neighbour 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 has 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 an inter- RAT cell on another site is made as a handover to co-located inter-frequency/inter-RAT cell and a handover to a intra-frequency cell located at the other site.
摘要翻译：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，因为小区间干扰与由小区向连接模式终端提供的质量的小区间干扰相比没有影响，而在UTRA中，小区内和小区间干扰细胞干扰对所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具有关于在各个频率载波上传输的功率的信息，并且可以调整从终端上报告的质量，定位的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，其中将跨频率切换到另一个站点上的RAT间小区作为切换到同位置的频间/ RAT间小区，并切换到位于另一个站点的频率间小区。

摘要： According to a first aspect of embodiments herein, the object is achieved by a method in a network node for assisting a first user equipment in interference mitigation. The network node is comprised in a cellular communications network. The cellular communications network further comprises the first user equipment and a second user equipment. The second user equipment causes interference to the first user equipment when at least one of the first user equipment and second user equipment communicate by using Device-to-Device, D2D communication. The network node obtains (202) information about the receiver of the first user equipment. The network node then determines (203) one or more parameters required by the first user equipment for mitigating the interference. The parameters relate to the obtained information and to the interfering second user equipment. The network node then sends (204) the one or more parameters to the first user equipment thereby assisting the first user equipment to mitigate interference caused by the second user equipment.

摘要： Several advanced features in wireless network, such as multi-carrier operation, multi-RAT/multi-mode transmission, etc., may not be exploited to their fullest potential when uplink transmit diversity is used in conjunction with them. Several techniques described herein address these problems. An example method begins with the evaluation (610) of operating conditions for a mobile terminal transmitter and, based on the operating conditions, selectively activating or deactivating (620) multiple-antenna transmission by the mobile terminal. The operating conditions that are evaluated include,in some embodiments, the applicability of power backoff (maximum power reduction, or "MPR"), including whether Additional MPR (A-MPR) or power management MPR (P-MPR) are applicable. Other operating conditions that are evaluated may include uplink data rate requirements or limitations for the mobile terminal, and/or the actual or estimated status of the battery in the UE.

摘要： A measuring node (700) in a wireless network (100) sets switching points for a plurality of measurement groups, performs measurements of signals transmitted from one or more cells corresponding to a group, and switches, at each switching point, from performing measurements according to one measurement group to performing measurements according to the next measurement group. The signals are transmitted by the cells in measurement occasions that repeat in a pattern. A switching point is a time by which the measuring node (700) node is expected to complete, at least in part, measurements of the one group and be ready to proceed with measurements of the next group. A configuring node (600) sends assistance data to the measuring node (700) to enable the measuring node (700) to determine the switching points for the measurement groups.
