Abstract: Aspects of the present disclosure relate to techniques for dynamic indication of Time Division Duplex (TDD) Uplink (UL)/Downlink (DL) subframe configuration to User Equipments. A base station may identify one or more anchor subframes and one or more non-anchor subframes in a frame. The base station may dynamically change a UL/DL configuration of the frame used for communicating with a plurality of User Equipments (UEs) and signal the changed configuration using a common downlink control channel capable of being interpreted by the plurality of UEs in at least one of the one or more anchor subframes of the frame.

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: Interference mitigation solutions are disclosed for interference experienced based on asymmetric uplink (UL)/downlink (DL) slot configuration. The aggressor/victim network entities are identified using either measurement or static/semi-static means, such that the victim network entities that may be impacted by interference from aggressor network entity transmissions are identified. Inter Cell Interference Coordination (ICIC) mechanisms are extended to negotiate and address scheduling that intelligently mitigates interference that occurs in the colliding slots.

Abstract: In aspects, methods and apparatus for utilizing a reconfiguration timer for updating TDD configuration are provided. Certain aspects of the present disclosure propose methods and apparatus for improving system performance while using adaptive uplink-downlink reconfiguration in a time division duplex (TDD) system. For certain aspects, a reconfiguration timer may be utilized along with a signaling scheme, in order to enjoy benefits of the adaptive uplink-downlink reconfiguration with minimum signaling overhead.

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 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.
