摘要： The disclosure relates to a method in a macro base station of a heterogeneous wireless communication system, for reducing uplink interference at a radio base station with restricted wireless access. The uplink interference is caused by a user equipment served by the network node, which has a restricted wireless access to the radio base station. The method comprises receiving (310) measurement reports from user equipments served by the network node, and identifying (320) a user equipment causing uplink interference at the radio base station among the user equipments, based on the received measurement reports. The method also comprises obtaining (330) information relating to a total uplink received interference from the radio base station via the identified user equipment, and adjusting (340) a transmit power, a transmission activity, and/or a scheduling of the identified user equipment based on the obtained information, such that the uplink interference caused by the identified user equipment is reduced.

摘要： In its various aspects, the present invention addresses the many challenges associated with making timing measurements involving multifarious radio links. Such measurements are referred to herein as "enhanced" to connote that such timing determinations are being made across multifarious radio links. Here, a radio link will be understood as connecting two radio nodes, and two radio links are considered to be multifarious with respect to each other if they are opposite in terms of uplink and downlink transmit directions, and further if they are associated with different cell identifiers and/or if the two links are between different pairs of radio nodes. In this context, the teachings herein disclose the sharing of "enhanced timing measurement" capability information, e.g., between radio nodes and positioning nodes. Such information indicates the enhanced timing measurement capability of a radio node. Sharing such information enables another node, e.g., a positioning node, to determine an enhanced timing measurement configuration to be used by a radio node. Further, additional teachings herein disclose advantageous configurations for making enhanced timing measurements, and techniques for compensating timing measurements determined from multifarious radio links, e.g., compensating for frequency-dependent propagation time differences.

摘要： Processing implemented by a method and apparatus herein advantageously addresses degradations to the quality of reference signal measurements and/or to the quality of serving cell data reception that would otherwise result from a wireless device (36) measuring different cells' reference signals over different bandwidths. The processing addresses these potential degradations by intelligently configuring the bandwidth over which different cells actually transmit reference signals. In this regard, the processing includes identifying (100) the cell bandwidth of each cell in a set of cells that transmit reference signals likely to be measured during a given measurement session of a wireless device (36). Processing then entails selecting (110), as a function of the cell bandwidths, a reference- signal bandwidth over which reference signals are to be transmitted from at least a subset of the cells in the set. Finally, processing includes configuring (120) at least each cell in the subset to transmit reference signals over said reference-signal bandwidth.

摘要： The auto-correlation properties of a reference signal or pilot pattern, such as a position reference signal (PRS) in a Long Term Evolution communication system, is improved by modifying the currently specified PRS patterns, and/or by PRS pattern shaping. Pattern shaping can result in creation of virtual PRS patterns, for example, by 5 controlling the PRS transmitted or received power used by the correlator. PRS power shaping can be implemented differently according to the location where the PRS power is calculated, e.g., in a network node or in a user equipment.

摘要： A base station (40-s) is configured to serve a wireless device (36) in a serving cell (42-s) on a serving frequency. The base station (40-s) obtains information that indicates one or more non-serving frequencies on which the device (36) is to perform one or more positioning measurements. These positioning measurements are to be used for determining the device's geographic position. For at least one non-serving frequency indicated by the information, the base station (40-s) configures a measurement gap during which the device (36) is to perform a corresponding positioning measurement. Specifically, the base station (40-s) configures such measurement gap to occur during a period of time in which a neighboring eel! (42-1, 42-2) transmits a positioning reference signal over that non -serving frequency. A positioning reference signal is specifically designed to be a signal on which a device performs positioning measurements. Thus, by aligning the measurement gap with a positioning reference signal, the positioning measurements will prove more reliable and accurate.

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).

摘要： A method of grouping cells of a radio communications network may include defining first and second groups of cells from a plurality of cells that transmit reference signals for positioning measurements. The first and second groups of cells may be defined according to a characteristic of the reference signals transmitted by the respective cells and/or of the respective cells that transmit the reference signals. Reference signals used for positioning measurements from the cells of the first group may be measured at a positioning target device. Reference signals used for positioning measurements from the cells of the second group may be measured at the positioning target device separately in time and/or separately in frequency from measuring the reference signals from the cells (103) of the first group.

摘要： Positioning and location services are provided in a wireless communication network (200) using civic address information. The civic address information may comprise a data structure including textual Information Elements such as apartment or office number, street number, street name, city, state, postal code, and the like. A positioning method is defined comprising performing a civic address lookup to obtain (14) a location in civic address format for an identified node (216), based upon information about the identified node's serving (or associated) node (220) and neighbor nodes (222). Signaling is defined to request the civic address positioning method, to exchange capabilities, to communicate (20, 114, 118) location information using a civic address format, report (124) a positioning failure and optionally the failure cause, and the like. Location information may be translated (116) between a civic address format and a 3GPP or 3GPP2 positioning format. The positioning method and associated signaling are particularly advantageous in indoor environments, where conventional positioning methods fare poorly or fail altogether.
