摘要： Method and arrangement in a positioning node and a user equipment,for providing, and retrieving, respectively, geographic region data. The geographic region data comprises geographic position data. The positioning nodeiscomprised in a wireless communication system. The positioning node receives geographic position data associated with the location point of a first user equipment. The positioning node also receivesa first radio fingerprint. The radio fingerprint is based on a first signal propagation time measurement, measured with respect to the location point of the first user equipment. The received first radio fingerprint is then associated with the received geographic position data and clustered together to create cluster boundaries, defining geographical region data. When a second radio fingerprint is received, this is compared with previously received radio fingerprints. If a correspondence is detected, the geographic region data of the previously received radio fingerprint is sent to the second user equipment.

摘要： A system obtains geographic positions associated with location points of multiple user equipments (UEs) in a wireless network and receives Evolved Universal Terrestrial Radio Access Network (E-UTRAN) radio fingerprint data associated with radio measurements performed at the location points by the multiple UE or performed by eNodeBs associated with the multiple UEs. The system clusters the location points based on similarities between the E- UTRAN radio fingerprint data to create cluster boundaries and stores the geographic positions, cluster boundaries and the E-UTRAN radio fingerprint data in a database for future determination of UE geographic positions using the E-UTRAN radio fingerprint data. The system receives E-UTRAN radio fingerprint measurement data associated with a first UE in the wireless network and performs a lookup operation into the database to retrieve one of the geographic positions that corresponds to the E-UTRAN radio fingerprint measurement data. The system sends the one of the geographic positions to at least one of the first UE. an emergency or police call center, a geographic information system (GIS) server or a node external to the wireless network.

摘要： Methods and apparatus for determining a position estimate for a base station transceiver node in a wireless communication system are disclosed. Angle-of-arrival and/or timing advance measurements corresponding to transmissions received from mobile stations for which geographic locations are already known are combined with known locations for the mobile stations to estimate the position of the base station receiving the transmissions. This estimated base station position may be used, for example, in subsequent positioning of mobile stations for which locations are not already known, such as mobile stations not equipped with GPS technology. The estimated base station position may also be used to update a database of base station coordinates for the wireless network.

摘要： A wireless communication network (10) determines positioning data (22) for a given mobile terminal (16), in response to receiving a positioning event trigger for that mobile terminal (16). The network (10) sends the positioning data (22) to the mobile terminal (16) via control-plane signaling, for transfer by the mobile terminal (16) to the user plane. Correspondingly, the mobile terminal (16) receives the positioning data (22) over the control plane, transfers it to the user plane, and transmits the positioning data (22) or location information derived from the positioning data (22), via user-plane signaling. As such, network-performed positioning measurements and/or geographic coordinate data derived therefrom are transferred from the control plane, to the user plane, for flexible and transparent transmission from the mobile terminal (16) to a given node (30, 90) having a user-plane connection with the mobile terminal (16). Such a node (30, 90) may be essentially any type of communication device, system, or server, internal or external to the network (10).

摘要： 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.

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.
摘要翻译：参考信号或导频模式（例如长期演进通信系统中的位置参考信号（PRS））的自相关属性通过修改当前指定的PRS模式和/ 或通过PRS图案整形。模式整形可以导致产生虚拟PRS模式，例如，通过控制由相关器使用的PRS发射功率或接收功率。根据计算PRS功率的位置，例如在网络节点或用户设备中，可以不同地实现PRS功率整形。
