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.

Abstract: Methods, systems, and apparatuses are described for flexible transmissions on one or more frequency division duplexing resources. In some aspects, a subset of resources originally allocated for transmissions in a frequency division duplex (FDD) mode of operation associated with a first base station is identified for reallocation, and the identified subset of resources is reallocated to transmissions in a time division duplex (TDD) mode of operation, for example, associated with a second base station.

Abstract: Cell selection techniques are provided for network access to cells that may employ one or more coverage enhancement techniques. A user equipment (UE), which may be a machine type communication (MTC) device, upon initial acquisition or upon wakeup may measure a reference signal received power (RSRP), reference signal received quality (RSRQ), or both, and determine a cell selection value based at least in part on the RSRP, RSRQ, or a combination thereof. The cell selection value may be determined based on an offset, which may be selected based on a measurement accuracy capability of the UE. UE sequential access attempts, neighbor cell list information that may include coverage enhancement of neighboring cells transmissions, and cell re-selection measurement frequency adjustments are also described.

Abstract: Aspects of the present disclosure provided techniques that may be applied in systems to allow for communication over a control channel utilizing a relatively narrowband (e.g., six physical resource blocks) based search space. An exemplary method, performed, for example, by a machine type communication (MTC) UE, generally includes identifying, within a subframe, a first search space to monitor for a control channel that occupies a first number of physical resource blocks (PRBs) that represents a narrowband within a system bandwidth comprising a plurality of narrowbands and monitoring at least the first search space for the control channel, wherein the control channel comprises broadcast control information.

Abstract: 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.

Abstract: 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.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus groups subframes of a time division duplex (TDD) configuration of a serving cell into a set of anchor subframes and a set of non-anchor subframes. The apparatus also separately bundles positive acknowledgements (ACKs) and/or negative acknowledgements (NACKs) of the anchor subframes, and ACKs and/or NACKs of the non-anchor subframes.
