    Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit a subframe that includes physical broadcast channel (PBCH) signals interspersed within beam reference signals, where the subframe may be a synchronization subframe including one or more synchronization signals. In some cases, the beam reference signals from different antenna ports may be code division multiplexed or frequency division multiplexed over multiple frequency tones. A user equipment (UE) may use the beam reference signals to generate channel estimates for the PBCH signals. In some cases, orthogonal cover codes for code division multiplexed signals may be selected to facilitate generation of channel estimates for PBCH signals transmitted using nearby frequency tones.

    Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may transmit downlink control information (DCI) messages to a user equipment (UE). A DCI message may be transmitted using a particular DCI format based on the type of control information included in the DCI message. In some cases, different types of control information may be transmitted using the same DCI format. In such cases, one or more bit fields in a DCI format may be useful to a UE for one type of control information but may not be useful to a UE for another type of control information. As described herein, in order to limit the overhead associated with control information transmissions, a base station may support techniques for utilizing these bit fields in a DCI format to transmit information corresponding to the type of control information being transmitted.

    Abstract: Aspects of the disclosure relate to devices for coordinating resource usage. A scheduled device receives a downlink control information (DCI) grant from a scheduling device, the DCI grant identifying scheduled resources for communicating data. The scheduled device decides whether the DCI grant is acceptable for communicating the data and sends an acknowledgement to the scheduling device based on the decision and information associated with the DCI grant. The scheduled device communicates the data via the scheduled resources when the DCI grant is decided to be acceptable. A scheduling device transmits the DCI grant to the scheduled device and receives the acknowledgement from the scheduled device based on the information associated with the DCI grant. The acknowledgement indicates whether the DCI grant is acceptable for communicating the data. The scheduling device communicates the data via scheduled resources identified in the DCI grant when the DCI grant is indicated to be acceptable.

    Abstract: The described techniques provide for the identification and utilization of different power consumption categories by a user equipment (UE) in wireless communications system. A power consumption category may correspond to a power consumption level (e.g., a powered circuitry configuration) of the UE. For example, a power consumption category may configure an analog-to-digital conversion (ADC) resolution, a digital-to-analog conversion (DAC) resolution, a number of antennas, etc., that a UE may employ for communications. In some examples, a UE may report capability information to a base station, and the base station may use the information to explicitly or implicitly (e.g., via conveying thresholds or conditions to the UE for power consumption category switching or power consumption category selection) configure the UE with various power consumption categories. As such, the power consumption categories may be used by the base station and UE, in some scenarios, for reducing power consumption.
