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： Certain aspects of the present disclosure relate to techniques for cross-carrier indication of TDD (Time Division Duplex) UL (Uplink)/DL (Downlink) subframe configuration. A UE may receive a configuration of a first index for a first cell, wherein the first index is mapped to a first position in a Downlink Control Information (DCI) message. The UE may receive the DCI message in a subframe and determine an indication of a UL/DL subframe configuration for the first cell based on the first index and the DCI message. The UE may communicate with the first cell based on the determined UL/DL subframe configuration for the first cell.

摘要： Aspects of the present disclosure relate to techniques that may help enable the determination of uplink resource allocation in systems that support dynamic uplink-downlink subframe configurations. An example method generally includes receiving signaling indicating a dynamic uplink-downlink (UL-DL) subframe configuration, determining hybrid automatic repeat request (HARQ) acknowledgment/negative acknowledgment (ACK/NACK) timing based on a reference UL-DL subframe configuration, and determining HARQ resource allocation based on the dynamic UL-DL subframe configuration.

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.

摘要： Methods, systems, and devices are described for interference mitigation between neighboring cells through the use of cell clusters and virtual logical cell clusters. Cells may be added to a cell cluster with a first cell when a level of interference coupling between the first cell and one or more neighboring cells exceeds a first threshold. One or more other cells may be added to a virtual logical cell cluster with the first cell when the level of interference coupling is between a second threshold and the first threshold, the second threshold being less than the first threshold. Interference mitigation between cells of cell clusters and/or virtual logical cell clusters may be performed. Interference mitigation may be accomplished through, for example, coordination of TDD uplink-downlink (UL-DL) configurations for cell clusters and scheduling-dependent interference management (SDIM) for virtual logical cell clusters.

摘要： A method, a computer program product, and an apparatus for separating a cell cluster to two or more cell clusters are provided. The cell cluster may be separated into two or more cell clusters in order to mitigate interference between cells while allowing for TDD subframe configuration flexibility. The method identifies at least one separating cell in a cell cluster, the cell cluster including at least two cells having a common TDD subframe configuration, where a coupling loss between one cell in the cell cluster and at least another cell in the cell cluster is lower than a predefined threshold. The method separates the cell cluster based on the at least one separating cell into at least a first cell cluster and a second cell cluster and sets a first TDD subframe configuration for the first cell cluster and a second TDD subframe configuration for the second cell cluster.
