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: 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.

Abstract: Methods, systems, and devices for wireless communications are described. A device (e.g., a base station or a user equipment (UE)) may identify a sequence length corresponding to a number of resource blocks, and select a modulation scheme based on the sequence length. The device may select, from a set of sequences associated with the modulation scheme, a sequence having the sequence length. In some examples, the set of sequences may include at least one of a set of time domain phase shift keying computer-generated sequences or a set of frequency domain phase shift keying computer-generated sequences. The device may generate a reference signal for a data transmission based on the sequence and transmit the reference signal within the number of resource blocks.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling indicating a set of resources for transmitting a set of uplink shared channel transmissions and a set of demodulation reference signals (DMRSs) having phase coherence across a set of transmission time intervals (TTIs). The UE may receive, from the base station, a control message indicating a cancellation of a first resource of the set of resources. The UE may determine one or more phase-continuity conditions for the set of resources based on receiving the control message indicating the cancellation of the first resource. The UE may transmit, in remaining resources of the set of resources, at least a subset of the set of uplink shared channel transmissions and at least a subset of the set of DMRSs in accordance with the one or more phase-continuity conditions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a wireless network device (e.g., a base station or a transmission reception point (TRP) of the base station), a first control message comprising an indication of a set of energy saving modes of the wireless network device. The UE may receive a second control message indicating a first energy saving mode from the set of energy saving modes, where the first energy saving mode may be indicative of a number of channel state information (CSI) reference signal (CSI-RS) resources used by the wireless network device. The UE may monitor one or more of the CSI-RS resources for a CSI-RS in accordance with the first energy saving mode, and transmit, to the wireless network device, CSI feedback determined based on measurements made by the UE of the CSI-RS.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for prioritizing, at a user equipment (UE), sidelink CSI reports received from other UEs. In one example, the UE may be configured to transmit sidelink CSI reports (e.g., received from other UEs) separately from other CSI reports (e.g., CSI reports generated by the UE), and the UE may prioritize sidelink CSI reports for transmission based on the priorities of the UEs from which the CSI reports are received. The UE may then aggregate and transmit the prioritized sidelink CSI reports to a network entity. In another example, the UE may be configured to transmit sidelink CSI reports with other CSI reports in a same channel, and the UE may prioritize the sidelink CSI reports over the other CSI reports for transmission to a network entity.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a signal indicating a wakeup opportunity associated with receiving one or more messages from an application and may identify a mapping between an attribute of the signal and an identifier associated with the application. The UE may determine a wakeup procedure in response to receiving the signal based on the mapping between the attribute of the signal and the identifier associated with the application.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE), that is configured for demodulation reference signal (DMRS) bundling, may receive a control message that schedules first and second sets of repetitions of an uplink transmission. The UE may determine a phase coherency configuration to be applied for DMRS transmissions corresponding to each set of repetitions. The phase coherency configuration may be determined based on a phase coherency capability of the UE, and the phase coherency configuration may specify that phase coherency is to be maintained for one or more of the first set of repetitions separate from one or more of the second set of repetitions. The UE may transmit the first set of repetitions with a first set of demodulation reference signals and the second set of repetitions with a second set of demodulation reference signals in accordance with the phase coherency configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform beam sweeping for a physical uplink channel within time domain windows or across time domain windows based on a time domain window index. In cases where frequency hopping is enabled, the UE may transmit uplink repetitions and demodulation reference signals (DMRSs) across two frequency hops during two consecutive time domain windows using a first transmit beam, and may then follow up with transmissions across two frequency hops during the next two consecutive time domain windows using a second transmit beam. Or, the UE may transmit uplink repetitions and DMRSs in a first frequency hop with first and second transmit beams during two respective consecutive time domain windows, and may transmit in a second frequency hop with the first and second transmit beams during the next two respective consecutive time domain windows.
