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： Methods, systems, and devices are described for discontinuous transmission and/or discontinuous reception in time division duplex (TDD) systems that may have data transmission formats dynamically reconfigured. An initial uplink-downlink (UL-DL) configuration for TDD communication between an eNB and user equipment (UE) may be established. This initial UL-DL configuration may be reconfigured to a different UL-DL configuration for one or more UEs in communication with the eNB. When a UE switches to discontinuous reception (DRX) mode, it may monitor control information from the eNB during DRX on periods, a frequency of the DRX on periods based on a reference UL-DL configuration irrespective of any reconfiguration of UL-DL configuration for a particular UE. In some aspects, a UE that is operating in a UL-DL reconfiguration mode may, upon entering DRX mode, autonomously discontinue operating in the UL-DL reconfiguration mode.

摘要： Methods, systems, and devices for wireless communication are described for mutual information based polar code construction. A wireless device may receive a codeword over a wireless channel, the codeword encoded using a polar code. The wireless device may identify a set of bit locations of the polar code corresponding to information bits of an encoded information bit vector. The set of bit locations may be determined based at least in part on a reliability order of the bit locations of the polar code, and the reliability order may be determined based at least in part on a recursive model that includes at least one mutual information transfer function that is applied at each polarization stage of multiple polarization stages of the polar code. The wireless device may decode the received codeword to obtain the information bit vector at the set of bit locations.

摘要： Enhancement of long term evolution (LTE) time division duplex (TDD) carrier aggregation for half duplex user equipments (UEs) is discussed. In one aspect of enhanced TDD carrier aggregation, the UE monitoring for a control signal indicating subframe configuration for each TDD cell of an aggregated set of TDD cells in the same band. The UE may determine the downlink subframes and receive downlink transmissions on such subframes based on the control signal. In another aspect, the UE compares the number of scheduled uplink and downlink subframes between the TDD cells in the same band to determine the downlink error-control messaging timing for each cell.

摘要： Methods, systems, and devices are described for providing periodic CSI reports and/or aperiodic CSI reports to provide CSI for both anchor and non-anchor TDD subframes in eIMTA. Periodic CSI reports may be provided based on a reference configuration, and aperiodic CSI reports may be provided based on a time of reception of a CSI request and a reference configuration. A UE may determine to report anchor or non-anchor CSI through explicit or implicit signaling. Aperiodic CSI may be used for transmission of anchor subframe CSI reports and periodic CSI may be used for transmission of non-anchor subframe CSI reports, or aperiodic CSI may be used for transmission of non-anchor subframe CSI reports and periodic CSI may be used for transmission of anchor subframe CSI reports. A determination of the reference subframe for aperiodic CSI estimation may be based on a time of receipt of an aperiodic CSI request.

摘要： Methods, systems, and-devices are described for interference mitigation in a time-division duplex(TDD)wireless communication system. First and second subframe types may be identified for TDD subframes to be transmitted using the system. Different power control parameters associated with each subframe type may be identified based on transmission directions in neighboring cells for the particular subframes. One or more TDD subframes to be transmitted may be identified as a first or second subframe type, and power control may be applied to the transmitted subframes according the power control parameter associated with the subframe type. The identification of subframes and power control parameters to be applied to each type of subframe may be transmitted, for example, to a user equipment(UE). The information may be transmitted to a UE, for example, via radio resource control(RRC)signaling or via a physical layer control channel.
