    摘要: Techniques for reporting timing information to facilitate data transmission on a downlink are described. A user equipment (UE) may receive signals from a plurality of cells available for data transmission to the UE. Each cell may have a different propagation delay to the UE. The UE may determine timing information based on the received signals and may report the timing information to one or more of the cells. The timing information may include a receive time of each cell at the UE. The UE may receive a data transmission from at least one cell, which can be selected from the plurality of cells, based on the timing information. The at least one cell may provide a coordinated or a non-coordinated data transmission. A coordinated transmission mode may be determined based on the timing information and can include, for example, a joint transmission, a coordinated beamforming, or a coordinated silencing.

    摘要: In 3GPP Release (Rel) 8, a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) may be transmitted in six resource blocks, occupying, for example, the center 62 tones (i.e., subcarriers) of an LTE-A system, wherein the center tone may be skipped. In synchronous networks, cells may transmit their respective PSS and SSS on the same frequency at the same time, wherein strong cells may overshadow the weak ones. However, strong cells may not be the serving cell for a user equipment (UE), particularly in a heterogeneous network. Traditionally, interference cancelation, an enhanced receiver technique, has been used, wherein the UE may first find the strong cells and cancel them out to find the serving cell. However, due to propagation delay and synchronization uncertainty, a timing offset may exist among cells, even in synchronous networks. Therefore, systems and methods are disclosed, providing for improved handling of the timing offset among different cells by applying a time domain cancelation.

    摘要: A method for ranking signals isolates and cancels neighboring cells using layering. Received signals from various cells are grouped into layers, with each layer comprised of received signals which are comparable within a particular metric (such as signal strength). The signals within a particular layer may also be ranked according to a desired metric. At the beginning of a cancellation cycle the UE may perform the layering and ranking. Once the layering and ranking has been performed the UE may continue to use the layering and ranking for later rounds of cancellation, freeing up processing resources that would otherwise be dedicated to repeated ranking of received signals. After a period of time, the cancellation cycle may repeat and the layering and ranking may be performed again.

    摘要: Encoders and decoders, and methods of encoding and decoding, are provided for rendering 3D images. The 3D images are decomposed by analyzing components of the 3D images to match reflections of patterns in the 3D images, and to restore the components for further rendering of the 3D image. The encoders and decoders utilize principles of reflective symmetry to effectively match symmetrical points in an image so that the symmetrical points can be characterized by a rotation and translation matrix, thereby reducing the requirement of coding and decoding all of the points in 3D image and increasing computational efficiency.

    摘要: Systems and methodologies are described that facilitate efficient cell acquisition in a wireless communication system. In one aspect, a reference signal for use in cell acquisition can be constructed in a bandwidth-agnostic manner such that it contains a common central portion in a predetermined frequency band that is independent of a bandwidth utilized by an associated wireless communication system. The central portion can be constructed as a two-dimensional block in time and frequency that spans a default cell search bandwidth, a predetermined bandwidth specified by synchronization codes or other signals, or another suitable bandwidth. A reference signal can then be constructed form the central portion by tiling or expanding the central portion such that it spans the entire system bandwidth.
