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.

摘要： At a cluster head/first device there is received, from each of at least two other devices with which the cluster head has a respective wireless link, a quality indicator for the respective link observed by the respective other device. The cluster head compiles those received quality indicators into a compressed report, and sends the compressed report to a network entity. In a specific embodiment the cluster head also determines an additional quality indicator of each of those respective links observed by the cluster head by listening to a sounding reference signal sent by the respective other device to the network entity on a PUCCH. Those additional quality indicators are also compiled into the compressed report, as are further quality indicators received from the devices for D2D links between pairs of those other devices that exclude the cluster head. The compressed report can inform how many indicators are above/below a threshold.

摘要： The specification and drawings present a new method, system, apparatus and software product for pilot scrambling using a scrambling code (e.g., pseudo-noise code such as a Gold code, a Kasami code, a Hadamard code, m-sequences, etc.) in communication systems, e.g., for wireless communications. The sector/cell specific scrambling codes are mapped to the multiple pilot symbols within, e.g., an SCH (synchronization channel) repetition period. This improves receiver performance on a sector edge and/or a cell edge in, e.g., tight-frequency re-use applications.

摘要： A wireless device is operated such that transmission and reception by the wireless device uses half-duplex frequency division duplexing. The wireless device transmits in an uplink subframe at a first frequency and receives in a downlink subframe at a second frequency. The uplink subframe and downlink subframe occur at different times. The frame structure that is used has a special subframe (80) to allow at least switching from downlink reception to uplink transmission. In one example, the special subframe (80) consists only of a downlink pilot time slot (85), to allow downlink pilot signals to be received at the wireless device, and a guard period (90), during which no data is received at or transmitted by the wireless device. In another example, the special sub frame (80) comprises a downlink pilot time slot (85) and a guard period (90), the special subframe (80) having no uplink pilot time slot for uplink pilot signals.

摘要： A network access node selects one chunk of spectrum from a plurality of chunks of spectrum to be a primary chunk for a particular cell; transmits in the primary chunk from a broadcast channel BCH that contains information needed by a terminal to at least perform initial cell access; and uses a synchronization channel SCH to indicate which chunk of the plurality of chunks is the primary chunk. A user equipment receives a SCH in a particular chunk of spectrum; determines from it that one chunk is a primary chunk for a particular cell; tunes its receiver to a BCH in the primary chunk and uses information received on the BCH to obtain initial access to the particular cell. In various embodiments the SCH is only in the primary chunk or the SCH has some indication (e.g., cell ID or relative position of primary chunk) telling which chunk is primary.
