    Abstract: A transmit beamforming gain and a receive beamforming gain may be used. when adjusting an uplink transmit power. For example, a user equipment (UE) may receive downlink communications from a base station on a receive beam having a beamforming gain that is different from a beamforming gain for an uplink transmit beam. The UE may adjust an uplink transmit power (e.g., for transmitting a random access channel (RACH)) based on a difference in the beamforming gains. For example, a parameter representing the difference in the beamforming gains, in addition to a maximum allowed transmit power, a target preamble received power, and an estimated path loss, may be used when determining an adjusted uplink transmit power for a RACH transmission. The adjustment may result in a higher or lower transmit power depending on the difference in the receive beamforming gain and the transmit beamforming gain.

    Abstract: Techniques are described for wireless communication. In one method, a user equipment (UE) receives a timing synchronization signal (TSS) and a physical broadcast channel (PBCH), with the TSS based at least in part on a timing of the TSS within a broadcast channel transmission time interval (BCH TTI); determines the timing of the TSS within the BCH TTI; and demodulates the PBCH based at least in part on the TSS. In another method, a base station allocates resources for a TSS and a PBCH within a BCH TTI; determines the TSS based at least in part on a timing of the TSS within the BCH TTI; and transmits, on the resources allocated for the TSS and the PBCH, the TSS and the PBCH, with the TSS transmitted as a demodulation reference signal (DMRS) for the PBCH on at least one port used to transmit the TSS and the PBCH.

    Abstract: Methods, systems, and devices for communication timing (e.g., random access channel (RACH) timing) in a wireless communication are described. A base station and a user equipment (UE) may perform a communication procedure (e.g., to establish a communication link between the base station the UE). The communication timing associated with the communication procedure may depend on the numerology used for the communication procedure and may be conveyed by the base station to the UE in a control message or via system information. In some cases, the numerology may indicate the communication timing.

    Abstract: Techniques are described for wireless communication. One method includes exchanging one or more signals between a first wireless node and a second wireless node and determining, at the first wireless node and based at least in part on the one or more signals, a range of correspondence between at least one of a transmit beam of the first wireless node and a receive beam of the first wireless node.

    Abstract: Antenna ports on wireless devices may be QCL. QCL antenna ports may be useful in improving channel statistics related to the antenna ports. UEs and base stations may be able to determine candidate QCL ports, transmit information identifying the candidate QCL ports, and receive feedback indicating whether the candidate QCL ports are QCL at the receiving device such as a UE or a base station.
