Abstract: A base station allocates uplink and/or downlink resources (e.g., in the time domain, frequency domain, spatial domain) to user equipment (UEs), or groups of UEs, that are subsequently reallocated. A base station determines a reallocation of uplink resources and/or downlink resources, and issues a cancellation indication or preemption indicator that corresponds to at least a portion of the previously allocated resources. UEs is configured to monitor for cancellation or preemption indicators, and based on received cancellation or preemption indicators, UEs determines whether or not to proceed with an uplink transmission or downlink reception using their previously allocated resources. Rules for application of cancellation or preemption indicators are identified by a UE and/or base station based on traffic prioritization and cancelation indication prioritization, based on types of scheduled reference signals to be transmitted by the UE, etc.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, via a sidelink interface, a message from a second UE. The UE may transmit, to the second UE, sidelink resource information for sidelink resources that are available to the second UE, wherein the sidelink resource information is based at least in part on a measured power level associated with the message received from the second UE. Numerous other aspects are provided.

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: Certain aspects provide a method for wireless communication by a first user equipment (UE), such as a receiver (RX) UE. The method generally includes receiving signaling configuring the first UE with a discontinuous reception (DRX) mode having one or more DRX ON durations for sidelink communications with at least a second UE, and deciding to extend a DRX ON duration of the one or more DRX ON durations configured for the first UE when the first UE is in the DRX ON duration and when one or more conditions are met.

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.
