摘要： The present invention provides a muting configuration for reference signal (RS) transmission as a pattern defined by at least the combination of a muting sequence and a reference point. Muting occasions for a given wireless communication network cell (20) thus are differentiated from another cell by use of a different muting sequence, a different reference point, or both. Moreover, in one or more embodiments, the present invention provides for the use of a common muting sequence or reference point across cells (20), with muting occasions being differentiated between cells (20) through use of different reference points (in the case of a common muting sequence), or through use of different muting sequences (in the case of a common reference point), or different sequences and different reference points. Such arrangements simplify the signaling needed to control or indicate the muting configuration in use in the cells of interest, provide an advantageous basis for propagating muting configurations among cells (20), eliminate the need for predefined muting configurations, and the need for blind detection of muting by wireless communication apparatuses (14), such as UEs.

摘要： A method is disclosed for using cell load coupling (CLC) to manage a radio communications network (RCN), comprising cells and radio network nodes associated with the cells. The method comprises determining a CLC characteristic between a first and second of the cells.

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.

摘要： Processing implemented by a method and apparatus herein advantageously improves the quality of measurements performed by a wireless device (36), by ensuring that the device (36) measures its serving cell over at least as large of a bandwidth as the bandwidth over which it measures neighbor cells. Such processing specifically includes identifying, for each of a plurality of neighbor cells, a measurement bandwidth over which the wireless device (36) is to perform measurements of that cell. Processing then entails selectively initiating handover of the wireless device (36) from a serving cell to one of the neighbor cells, depending on how many of those neighbor cells have a measurement bandwidth larger than that of the serving cell. Thus, contrasted with traditional performance- based handovers that are conducted based on the strength of already made reference signal measurements, handover herein is performed based on the bandwidth(s) over which such measurements will be performed in the future.
摘要翻译：通过本文的方法和装置实现的处理有利地通过确保设备（36）至少与其测量的带宽一样大的带宽来测量其服务小区来改善由无线设备（36）执行的测量的质量相邻细胞。这种处理具体包括为多个相邻小区中的每一个识别测量带宽，无线设备（36）将通过该测量带宽执行该小区的测量。然后处理需要有选择地启动无线设备（36）从服务小区到相邻小区之一的切换，这取决于这些相邻小区中的多少具有比服务小区的测量带宽大的测量带宽。因此，与基于已经做出的参考信号测量的强度进行的传统基于性能的切换相反，这里的切换是基于将来将进行这种测量的带宽来执行的。

摘要： in a multi-carrier wireless communication network (10), positioning-aware switching (106, 208) of a primary carrier from a first carrier to a second carrier for a UE (12) is constrained to enable one or more positioning measurements (204) to be performed. Either the selection (104) of the second carrier, the timing of switching (106) from the first to the second carrier, or both, are constrained to enable and enhance the positioning performance. The constraints may be operative at a serving node (32) of the network (10), at a UE (12), or both. Further constraints may be applied to the network (10) to enhance positioning performance. Carrier switching (106, 208) may be across Radio Access Technology, RAT (40, 50), and the positioning constraints may include configuring or re-configuring a device to perform positioning measurements (204) in measurement gaps (e.g., on a secondary carrier in LTE systems when Positioning Reference Signals are not transmitted on the primary carrier).
