    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station as part of a wireless communications system. The UE may identify a configuration for one or more repetitions of an uplink control channel transmission, where each repetition of the one or more repetitions including a first quantity of symbols. The UE may determine a power level for each repetition of the one or more repetitions. The UE may then identify that a second quantity of symbols is available to the UE to transmit a repetition of the one or more repetitions, and the second quantity of symbols may be less than the first quantity of symbols indicated by the configuration. The UE may transmit, to a base station, the repetition on the using the power level.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) configured for a periodic channel stat information (CSI) reference signal (CSI-RS) configuration may request an update for one or more parameters of the periodic CSI-RS configuration. For example, the UE may transmit request to a base station for a longer periodicity based on detecting a low Doppler scenario or little variance to wireless channel conditions, or the UE may request a shorter periodicity based on detecting a high Doppler scenario or high variance to wireless channel conditions. The base station may update a configuration for CSI or for CSI-RS based on the request. For example, the base station may update a periodicity for the periodic CSI-RS configuration based on the requested periodicity.

    Abstract: Aspects of the disclosure relate to techniques for peak-to-average power ratio (PAPR) reduction based on a tone reservation (TR) algorithm. For a TR algorithm, a suitable subset of tones from among a full set of tones in a given resource allocation are reserved for use as peak reduction tones (PRT). An apparatus, such as a wireless communication device, selects a set of PRTs based on a deterministic pseudo-random tone selection algorithm, such as quadratic sampling, cubic sampling, or Fibonacci-type sampling. The apparatus determines a PAPR reduction waveform for transmission on the PRTs and transmits a data waveform multiplexed with the PAPR reduction waveform on resources corresponding to the resource allocation. Other aspects, embodiments, and features are also claimed and described.
