    摘要: The present disclosure relates to systems and methods for a two-dimensional discrete Fourier transform based codebook for elevation beamforming. A two-dimensional discrete Fourier transform based codebook is determined for elevation beamforming. The codebook supports single stream codewords and multistream codewords. The two-dimensional discrete Fourier transform based codebook is generated by stacking the columns of the matrix product of two discrete Fourier transform codebook matrices. The codebook size may be flexibly designed based on required beam resolution in azimuth and elevation. A best codebook index is selected from the generated two-dimensional discrete Fourier transform based codebook. The selected codebook index is provided in a channel state information report. The channel state information report is transmitted to a base station.

    摘要: Methods, systems, and devices are described for reconfiguring a user equipment (UE) to operate in a reconfigured TDD UL-DL configuration. An initial uplink-downlink (UL-DL) configuration for TDD communication may be provided for communication between an e Node B and a UE. One or more subframes within each frame transmitted using the initial UL-DL configuration may be identified as flexible subframes. The identification of flexible subframes may permit the identification of timing for HARQ transmissions that does not change when a reconfiguration takes place. A different UL-DL configuration may be transmitted to the UE, in which at least one flexible subframe is to be changed from an uplink subframe to a downlink subframe. The different UL-DL configuration may be transmitted by, for example, a pseudo-uplink grant to the UE, which indicates that the UE is to reconfigure one or more flexible subframes from uplink to downlink transmission.

    摘要: Dynamic intra-cluster coordination for TDD UL-DL reconfiguration using distributed TDD UL-DL reconfiguration techniques and/or new physical layer signaling. Cell weighting techniques may be used so that distributed TDD UL-DL reconfiguration of the cell cluster can be weighted towards cells of the cluster with higher load. Cells within a cell cluster may independently determine their preferred TDD UL-DL reconfiguration and one or more cells of the cluster may be eligible cells for determining the TDD UL-DL reconfiguration for the cluster. Special subframes may be used for transmission of TDD UL-DL reconfiguration messages from the configuring cell and transmission of ACK messages from other cells of the cluster. The TDD UL-DL reconfiguration message may be an orthogonal sequence based on a signature determined by the cell ID of the configuring cell.

    摘要: A method and apparatus for wireless communication may provide for mobility in a Multi-Point HSDPA network capable of downlink aggregation. Some aspects of the disclosure provide modified mobility events utilized for altering the Active Set for a UE. Here, the addition of a cell to the Active Set can coincide with making that cell a secondary serving cell. Further, the deletion of a secondary serving cell from the Active Set can coincide with switching off the Multi-Point HSDPA mode. Still further, a modified mobility event for an HSDPA serving cell change can be utilized to swap a primary serving cell and a secondary serving cell.
