Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may receive, from a network entity, a request to provide an enhanced positioning measurement report comprising a positioning measurement and further comprising a report of components of a channel power delay profile (PDP), a report of a probability distribution of times of arrival (ToA), or both. The UE may determine an enhanced measurement period required by the UE to perform the enhanced positioning measurement, wherein the enhanced measurement period is longer than a standard measurement period required by the UE to perform a non-enhanced positioning measurement. The UE may perform the enhanced positioning measurement using the enhanced measurement period. The UE may provide the enhanced positioning measurement report to the network entity.

Abstract: Methods, systems, and devices for wireless communications are described. A configuration for a reference signal used to determine a non-linear behavior of transmission components at a transmitting device may be determined. The configuration for the reference signal may be determined based on signaling transmitted by the transmitting device, signaling transmitted by a device that receives the reference signal, or both. Additionally, or alternatively, the configuration for the reference signal may be determined based on a configuration of other signals transmitted by the transmitting device prior to or concurrently with the transmission of the reference signal. The determined configuration may be used to generate and transmit the reference signal or to determine a configuration of a received reference signal. In both cases, a non-linear response of transmission components at the transmitting device may be determined based on the reference signal.

Abstract: Certain aspects of the present disclosure provide techniques for generating and decoding orthogonal frequency division (OFDM) waveforms with peak reduction tones (PRTs) designed to reduce PAPR. By generating PRT tones with a machine learning (e.g., neural network) based encoder and mapping some of the PRT tones to subcarriers used for physical channels or signals, PAPR may be reduced while efficiently using system resources.

Abstract: Methods, systems, and devices for wireless communications are described. According to one or more aspects, a device, such as a user equipment (UE), may receive downlink control information, and may determine assignment information for processing batch-based feedback based on the downlink control information. The UE may determine the batch-based feedback for a batch of downlink transmissions (for example, transmissions associated with packets of information) that are configured to be processed together by the UE. The UE may receive a downlink transmission from the base station, and may construct a codebook based on assignment information and the downlink transmission. In some examples, the UE may determine acknowledgment feedback for the downlink transmission based on the codebook. The UE may transmit the acknowledgment feedback to the base station.

Abstract: Disclosed are techniques for group reporting of UE receive-transmit (Rx-Tx) time difference measurements for multi-RTT positioning. A plurality of downlink reference signals (DL RSs) are received from a plurality of transmission reception points (TRPs). A corresponding plurality of uplink reference signals (UL RSs) are transmitted to the plurality of TRPs. One or more numerology factors are determined for the plurality of TRPs. A measurement report is generated for the plurality of TRPs based on the numerology factors. The measurement report is transmitted to a network entity. The measurement report includes UE receive-transmit (Rx-Tx) time difference measurements for at least two of the TRPs.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) capable of supporting multiple antenna ports may determine that some combinations of antenna ports can be used simultaneously. The UE may make this determination by evaluating the relationships between the physical antennas and the transmit chains included in the UE. Upon determining that the combinations of antenna ports can be used simultaneously, the UE may send a message to a base station. The message may indicate whether two or more antenna ports can be used at the same time. The UE may communicate simultaneously over one or more antenna ports based on the scheduling information from the base station which takes into account the ability of the combination of antenna ports to be used concurrently.

Abstract: Disclosed are techniques for measuring round trip times (RTTs) between a user equipment (UE) and a plurality of transmission-reception points (TRPs). In an aspect, the UE receives a positioning configuration message from a TRP, measures a time of arrival (TOA) of each of a plurality of positioning signals from the plurality of TRPs, and transmits, to the TRP, a RACH positioning Message A on uplink resources defined in the positioning configuration message, and receives, from the TRP, a RACH positioning Message B subsequent to transmitting the RACH positioning Message A, wherein the RACH positioning Message A includes a first plurality of positioning measurements corresponding to the plurality of TRPs, the RACH positioning Message B includes a second plurality of positioning measurements corresponding to the plurality of TRPs, or any combination thereof.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for signaling channel preemption indications that enable a user equipment (UE) of a first type to take one or more actions on resources that are re-allocated to an UE of a second type. An exemplary method generally includes determining that resources allocated for a scheduled transmission by a first user equipment (UE) of a first type overlaps with uplink channel resources allocated to a second UE of a second type. The method also includes signaling, based on the determination, an uplink preemption indication (ULPI), to the second UE, that identifies at least some of the overlapping resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a downlink configuration including a set of resources for receiving downlink transmissions. The UE may determine, based on the downlink configuration, an uplink configuration including a set of resources for transmitting scheduling requests at a set of scheduling request occasions. In some aspects, the set of scheduling request occasions may be arranged according to a non-uniform spacing pattern in the time domain. The UE may transmit, to a base station, one or more scheduling requests based on the uplink configuration.
