    Abstract: 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.

    Abstract: Certain aspects of the present disclosure relate to methods and apparatus for measuring and mitigating interference. Such interference may include base station to base station (eNB to eNB) interference and/or UE to UE interference. A base station may determine a first subframe configuration for the base station and a second subframe configuration for one or more other base stations, wherein the first and second subframe configurations have different ratios of uplink to downlink portions. The base station may measure interference caused by the one or more other base stations based on reference signals transmitted in downlink portions of the second subframe configuration.

    Abstract: 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 a base station and a UE. One or more subframes may be identified within at least one half of each frame transmitted using the initial UL-DL configuration as flexible subframes. In one example, a reconfiguration message may be received in a first frame indicating that a transmission direction for the at least one flexible subframe of a second frame is to be changed. The reconfiguration message may include, for example, a two-bit configuration indication which indicates that the UE is to reconfigure a transmission direction for one or more flexible subframes in an associated half-subframe of a second frame.

    Abstract: Enhanced power control for scheduling in a time division duplex (TDD) heterogeneous network is disclosed in which sounding reference signals (SRS) transmitted by a pico user equipment (UE) to its pico base station are used by the macro base station in estimating the channel to the pico UE. The macro base station uses the estimated channel to schedule its served macro UEs. In selected aspects, the pico UE determines the path-loss transmission power to the macro base station and transmits at least one of its SRS using an enhanced power that accounts for the path-loss. In additional aspects, the macro base station schedules macro UEs to reduce interference during the times when the pico UE transmits SRS. The stronger power of the SRS or reduced interference allows the macro base station to obtain a more accurate channel estimation, which results in improved interference cancelation.

    Abstract: The effects of downlink-to-uplink interference are mitigated in TDD systems by adapting timing for uplink control information and UL HARQ retransmission. In some embodiments, uplink control information may be shifted to subframes that experience lower downlink interference from other cells. In some embodiments, UL HARQ timing is modified such that UL transmissions and retransmissions experience similar interference profiles. In embodiments, asynchronized UL HARQ may be used to schedule retransmissions in UL subframes with similar interference profiles as the original transmission (e.g., either UL-UL interference or DL-UL interference, etc.). In other embodiments, modified synchronous UL HARQ timing adapts retransmission to occur on UL subframes with similar interference profiles as the transmission based on the TDD UL-DL configuration of the serving cell and/or interfering cells.

    Abstract translation: 通过适应上行链路控制信息和UL HARQ重传的定时，在TDD系统中减轻了下行链路到上行链路干扰的影响。 在一些实施例中，上行链路控制信息可以被转移到经历来自其他小区的较低下行链路干扰的子帧。 在一些实施例中，修改UL HARQ定时，使得UL传输和重传经历相似的干扰分布。 在实施例中，异步UL HARQ可以用于在具有与原始传输（例如UL-UL干扰或DL-UL干扰等）相似干扰简档的UL子帧中调度重传。 在其他实施例中，修改的同步UL HARQ定时使得重发发生在具有与基于服务小区和/或干扰小区的TDD UL-DL配置的传输相似的干扰简档的UL子帧上。

    Abstract: 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.
