Abstract: Methods, systems, and devices for wireless communication are described. A receiving device may detect a signal associated with low latency transmissions and decode a non-low latency communication accordingly. The receiving device may receive an indicator from a transmitting device that indicates where and when low latency communications occur. The indication may specify frequency resources or symbols used by the low latency communication. The indicator may be transmitted during the same subframe as the low latency communication, at the end of a subframe, or during a subsequent subframe. The receiving device may use the indicator to mitigate low latency interference, generate channel estimates, and reliably decode the non-low latency communication. In some cases, the interfering low latency communication may occur within the serving cell of the receiving device; or the interfering low latency communication may occur in a neighboring cell.

Abstract: Certain aspects of the present disclosure provide methods, apparatus, and computer-program products for the detection of potentially interfering or interfering user equipment (UE) in the proximity of a detecting entity. The detecting entity may be a base station or a UE. In an aspect, the proposed detecting scheme utilizes semi-static system information from one or more neighboring base stations (BSs), and identifies a neighbor BS's UE that causes interference in the physical uplink control channel (PUCCH). The proposed detecting scheme may also identify corresponding resources that are allocated to an interfering UE by the interfering neighbor base station. In aspects, detecting schemes may not utilize information from one or more neighboring BSs.

Abstract: Techniques are described for wireless communication. A method for wireless communication may include identifying interference at a first node operating in a shared radio frequency spectrum band. The interference may be caused by a second node operating in the shared radio frequency spectrum band. The second node may operate asynchronously to the first node in the shared radio frequency spectrum band. The method may also include adaptively enabling, based at least in part on the identified interference, a synchronization of the first node with at least a third node in the shared radio frequency spectrum band.

Abstract: Methods, systems, and devices are described for reference signal design in wireless communications. A base station may select a reference signal density scheme from a set of available density schemes associated with a port count. The reference signal density scheme may also be selected based on the category of the mobile device receiving the reference signal transmissions. The reference signal density scheme may be a higher density reference signal density scheme or a lower density reference signal density scheme, where the higher density reference signal density scheme includes more reference signal resource elements per subframe. The mobile device may determine the reference signal density scheme based on characteristics of a channel. The higher density reference signal density scheme may provide additional channel estimation opportunities for the mobile device. In some cases, the mobile device sends the channel estimated based on the received reference signals to the base station.

Abstract: Dual-thread feedback for non-orthogonal channels used in wireless communications systems is described. A first feedback thread may employ transmission strategy (TS) independent feedback and a second feedback thread may employ TS dependent feedback. The first feedback thread may include channel feedback from channel measurements (e.g., channel gain, noise covariance, etc.) and may be fed back periodically. A TS space may be determined that includes combinable TSs for UEs that may be grouped for non-orthogonal techniques, and one or more TS sets may be sent to the UEs. UEs may determine channel quality and/or other channel state information (CSI) for the TSs and report CSI for one or more TSs of the TS sets in a second feedback thread. Scheduling may be performed for transmissions to the UEs based on the feedback in the first and/or second feedback threads.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE receives synchronization signals and an information block from a first base station. The information block includes information indicating whether the first base station is in a dormant state or an active state. The UE detects the first base station based on the received synchronization signals and on the information indicating whether the first base station is in the dormant state or the active state. The UE may receive, from a second base station, an indication of resources for detecting the first base station. The synchronization signals and the information block may be received in the indicated resources. The UE may move to the first base station from a second base station in a handoff from the second base station to the first base station.
