Abstract: Certain aspects of the present disclosure provide methods for wireless communications by a base station and a user equipment in a network. An exemplary method generally includes performing a discovery procedure to identify one or more devices through which the UE may indirectly communicate with a base station in the network and deciding based on one or more criteria whether to communicate with the base station directly or to communicate with the base station indirectly via a device identified by the discovery procedure. According to certain aspects, when a UE is in communication with a network indirectly, the network might page the UE directly, indirectly, or both.

Abstract: Methods, systems, and devices are described for wireless communication employing two-stage control channel messaging. Systems, methods, and apparatuses for two stage two-stage physical downlink control channel (PDCCH) with a downlink control information (DCI) flag and DCI format size indicator are described. For instance, the present disclosure presents an example method of wireless communication at a wireless device, which may include receiving, at a first bandwidth and during a transmission time interval (TTI), a first control channel message. In addition, the example method may include determining, based on a flag in the first control channel message, whether a second control channel message is present in the TTI. Furthermore, the example method may include receiving, at a second bandwidth, the second control channel message where the flag indicates that the second control channel message is present for the TTI.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in connection with specifying a traffic-to-pilot (T/P) ratio per subframe and/or resource block to allow a base station to transmit over the subframes and/or resource blocks using varying transmit powers. In one example, a device communicating with the base station can receive a plurality of T/P ratios each related to a power used by the base station to transmit over one of a plurality of carriers in a specific subframe or resource block, determine a power of a reference signal received from the base station over a carrier of the plurality of carriers, and process a data signal received over the carrier within the specific subframe or resource block based in part on applying, to the power of the reference signal, a T/P ratio of the plurality of T/P ratios corresponding to the carrier.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for employing a neighboring cell's assistance information for interference mitigation (e.g., by conveying the information to a user equipment). A base station (BS) may determine assistance information for a neighboring cell and convey it to a user equipment (UE). A UE may receive assistance information for a neighboring cell and use that information for performing interference cancellation or suppression on received signals. The UE may receive the assistance information from a serving cell or a non-serving cell. The assistance information may be valid for a particular transmission instance, for a known period of time, or until updated by a BS.
