摘要： Systems and methods for providing improved location such as emergency services location of mobile devices in an over the air communications system are disclosed. On receiving a request, a user equipment (UE) mobile device makes observed time difference of arrival (OTDOA) measurements on signals received from certain cell communication elements. The UE selects or prioritizes the cells based on one of several schemes, including comparing internally stored cell ID information to cell ID information provided by the network, and using lists of cells that are recently used, recently received, previously used, or on a closed subscriber group (CSG) list are alternative embodiments. The UE may prioritize home eNB cells that it is a member of for the measurements. By prioritizing the cells used for the measurements, the OTDOA measurements may be limited to a few cells and the time needed to make the measurements may be reduced.

摘要： In accordance with an example embodiment of the present invention, a method comprises receiving a plurality of reference signals (RS) from a plurality of nearby cells over a positioning time window comprising a plurality of positioning occasions; grouping the received reference signals into a set of RS groups based on a time difference between a minimum expected RS time difference (RSTD) and a maximum expected RS time difference of the received signals; buffering a subset of the set of RS groups of the received reference signals in a RS buffer whose size is based at least in part on a buffering margin and is smaller than a maximum possible time difference; measuring the buffered reference signals; and generating an observed time difference of arrival (OTDOA) report based on the buffered subset of the set of RS groups of the received reference signals.

摘要： An apparatus and method for inserting a cyclic postfix for a time-rotated symbol in a communication system. In one embodiment, the apparatus includes a time pre-rotation module configured to time shift bits of at least one of ending samples of a symbol to a beginning of the symbol to form a time-rotated symbol. The apparatus also includes an interpolator configured to construct an up-sampled symbol from the time-rotated symbol and a cyclic postfix module configured to insert a cyclic postfix at an end of the up-sampled symbol to form an expanded up-sampled symbol.

摘要： A method and apparatus are provided for timed estimation-based positioning of a user equipment in LTE systems. The method includes estimating, by a mobile node, a plurality of reference signal time differences (RSTD) between the mobile node and a network node. The plurality of RSTD estimates define a first correlator. The method further includes determining a second correlator of RSTD estimates, and defining the second correlator with the first correlator based on a mean of the plurality of RSTD estimates. Further, the method includes determining a distribution of the plurality of RSTD estimates, and grouping clusters of RSTD estimates in the distribution. Additionally, the method includes selecting a cluster from the clusters of RSTD estimates. The cluster includes RSTD estimates closest to a center of the second correlator. The cluster is transmitted, by the mobile node, to the network node for positioning the mobile node in a communications network.
