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 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 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.

Abstract: The present invention relates to methods and arrangements for handling unreliable scheduling grants in a WCDMA-communication system. A user equipment detects that a received scheduling grant is unreliable and adjust its serving grant based on that information. The user equipment is also able to report continuously received unreliable grants as an event to the network, allowing the network to adapt its operation to reduce the unreliable grants.

Abstract: 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.
