    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support machine learning (ML)-based positioning that mitigates user equipment (UE) clock drift. In some aspects, a UE may receive, from a network entity, positioning configuration that indicates positioning operations to be performed to gather training data to train an ML positioning model to account for UE clock drift. The UE may monitor for positioning reference signals from a transmit/receive point and transmit positioning measurements to a training entity. The positioning measurements may include multiple measurements at a fixed location, or the UE may augment the positioning measurements based on simulated clock drift measurements. Alternatively, the UE may transmit clock drift information with the positioning measurements to the training entity. Alternatively, the UE may utilize a hybrid approach that combines multiple positioning measurements with augmentation or providing clock drift information. Other aspects and features are also claimed and described.

    Abstract: A wireless device may receive a configuration message including a configuration to measure a first set of positioning signals associated with a first antenna and to measure a second set of positioning signals associated with a second antenna. The wireless device may receive the first set of positioning signals associated with the first antenna and the second set of positioning signals associated with the second antenna. The wireless device may measure the first set of positioning signals associated with the first antenna and the second set of positioning signals associated with the second antenna. The wireless device may transmit a set of report messages including a first indicator of a first subset of the measured first set of positioning signals associated with the first antenna and a second indicator of a second subset of the measured second set of positioning signals associated with the second antenna.

    Abstract: This disclosure provides methods, components, devices and systems for managing a multi-traffic identifier (TID) and multi-link block acknowledgment (BA) negotiation scheme. In some aspects, to negotiate a setup session between wireless communication devices, a first wireless communication device may transmit a request message including an information container that includes one or more negotiation parameter sets each associated with a type of traffic. For example, a type of traffic may correspond to a TID or a resource reservation for a particular traffic flow. Each negotiation parameter set may indicate functionalities being negotiated for the setup session. In association with the negotiation, a second wireless communication device may transmit a response message to the first wireless communication device that includes values for the negotiation parameter sets. For example, the response message may include an acknowledgment (ACK) indicating an acceptance of one or more of the parameter sets for the setup session.

    Abstract: Some techniques and apparatuses described herein enable transmission of an uplink control channel in a cross-carrier fashion, where determination of a slot for the transmission is performed based at least in part on a reference component carrier (CC), of a plurality of CCs. For example, the reference CC may be indicated by scheduling information associated with a downlink channel, or may be determined by the UE (e.g., based at least in part on an order associated with the plurality of CCs and availability of a slot for an uplink control channel on the plurality of CCs). In this way, ambiguity with regard to determination of the slot for transmission of the uplink control channel is reduced, thereby providing improved control channel performance, improved resource utilization, and more robust implementation of cross-carrier uplink feedback.

    Abstract: The aspects described herein may enable an apparatus to jointly encode two or more payloads using a single polar encoder device, while providing unequal error protection for the payloads. The apparatus causes a polar encoder to polar encode a first payload and a second payload to generate a polar encoded codeword. The polar encoder is configured to encode one or more bits of the first payload at a first reliability level and encode one or more bits of the second payload at a second reliability level, where the one or more bits of the first payload are associated with a first priority level and the one or more bits of the second payload are associated with a second priority level. The apparatus transmits the polar encoded codeword.

    Abstract: This disclosure provides methods, components, devices and systems for signal generation. Some aspects more specifically relate to frequency-selective digital predistortion signal generation. In some examples, the method alters an input signal to produce a frequency-selected linear output signal of a power amplifier. For frequency-selective pre-distortion signal generation, a digital pre-distortion circuit suppresses the non-linear distortion at a specific band using Volterra kernels of a Volterra series model and a shiftable finite impulse response (FIR). The shiftable FIR can filter a particular portion of the signal's frequency, and the Volterra kernels can capture the non-linear memory effects of the input signals and output signals of the power amplifier. Upon refinement of the Volterra kernel coefficients, the Volterra series model can produce a compensation signal. The shiftable FIR can filter the compensation signal to produce a digital pre-distortion signal to input into the power amplifier for transmission.

    Abstract: Techniques for generating a power tracking supply voltage for a circuit (e.g., a power amplifier) are disclosed. The circuit may process multiple transmit signals being sent simultaneously on multiple carriers at different frequencies. In one exemplary design, an apparatus includes a power tracker and a power supply generator. The power tracker determines a power tracking signal based on inphase (I) and quadrature (Q) components of a plurality of transmit signals being sent simultaneously. The power supply generator generates a power supply voltage based on the power tracking signal. The apparatus may further include a power amplifier (PA) that amplifies a modulated radio frequency (RF) signal based on the power supply voltage and provides an output RF signal.
