Abstract: Techniques for handover into eIMTA enabled cells are disclosed. In an aspect, a target cell reconfigures RRC connection with a UE after completed handover to enable eIMTA and/or CoMP for the UE. In another aspect, a target cell includes eIMTA configuration information in a handover command to a UE. In another aspect, the target cell may estimate a virtual cell identity to generate the eIMTA configuration information and delay scheduling transmissions to the UE by flexible subframes until after handover is complete and the correct eIMTA configuration information confirmed by measurement or else corrected by RRC connection reconfiguration. In other aspects, the target cell may determine the correct virtual cell identity before handover, either by measuring SRS of the UE, or by receiving information in a handover request indicating results of CSI-RS measurement, by the UE, of virtual cells of the target cell.

Abstract: Techniques for uplink transmission management in a wireless communications system are described herein. An example method may include receiving an explicit uplink grant that indicates one or more implicit uplink grants. In an aspect, the example method may include performing a first clear channel assessment (CCA) in response to the explicit uplink grant in a first time slot. In another aspect, the example method may include, if the first CCA fails, sequentially performing one or more additional CCAs respectively in one or more time slots subsequent to the first time slot in response to the one or more implicit uplink grants, and transmitting the PDU over the unlicensed or shared spectrum and in a time slot subsequent to the time slot in which one of the one or more additional CCAs succeeds.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives, by a user equipment (UE) during a first subframe, an indication of a dynamic uplink/downlink (UL/DL) subframe configuration. The apparatus determines an uplink hybrid automatic repeat request (HARQ) timing based on an uplink reference subframe configuration and at least one of the dynamic UL/DL subframe configuration or a downlink reference subframe configuration. The apparatus selects an uplink subframe for communication based on the determined uplink HARQ timing.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines an interference type between a time division duplex (TDD) configuration subframe of a serving cell and a corresponding TDD configuration subframe of a neighboring cell, and sets a transmit power for an apparatus in the serving cell based on the interference type. The apparatus in the serving cell may be a user equipment (UE), in which case the apparatus applies a set of uplink (UL) open loop power control parameters for the UE. The apparatus in the serving cell may be a base station (eNB), in which case a DL transmit power is set for the eNB. Depending on the interference type, the DL transmit power may be a fixed, full power DL transmission or an adjusted DL transmission.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE determines a first CSI subframe set including a first set of subframes of a frame and a second CSI subframe set including a second set of subframes of the frame. Subframes in the first set of subframes are different than subframes in the second set of subframes. The UE determines a CSI reference subframe in one of the first CSI subframe set or the second CSI subframe set. The UE measures CSI in the CSI reference subframe. The UE receives an aperiodic CSI request in a triggering subframe in one of the first CSI subframe set or the second CSI subframe set. The triggering subframe is after the CSI reference subframe.

Abstract: 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.

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.
