Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be configured to transmit positioning reference signals (PRSs) to a second UE in an unshared radio frequency spectrum and transmit supplemental PRSs to the second UE in a shared spectrum. The second UE may then use the supplemental PRSs in addition to the PRSs in the unshared spectrum to compute a position of the first UE. In some cases, the first UE may signal a configuration for the supplemental PRSs to the second UE, and, in other cases, a base station may signal the configuration for the supplemental PRSs to the second UE. In any case, because the second UE may use both the PRSs in the unshared spectrum and the supplemental PRSs to compute the position of the first UE, the accuracy of the computed position of the first UE may be improved.

Abstract: Certain aspects of the present disclosure provide techniques for beam management using adaptive learning. Certain aspects provide a method that can be performed by a node, such as user equipment (UE) or a base station (BS). The node determines one or more beams to utilize for a beam management procedure using adaptive learning. The node performs the beam management procedure using the determined one or more beams. In some aspects, the node uses an adaptive reinforcement learning algorithm to select beams for measurement in beam discovery procedure. The node may adaptive the beam management algorithm based on feedback associated with the beam selection, such as based on a throughput achieved using a beam pairing determined during the beam management procedure.

Abstract: Various aspects described herein relate to cancelling interference in wireless communications. Energy level detection of a received signal can be performed to determine an allocation size and position corresponding to an interfering device in the received signal. An interference demodulation reference signal (DM-RS) and cyclic shift of the interfering device in the received signal can be determined. It can be determined whether to apply successive interference cancellation on the received signal, based at least in part on the allocation size and position and the DM-RS and cyclic shift, to cancel interference from the interfering device.

Abstract: A wireless device may identify a first subband in an unlicensed radio frequency spectrum band used to communicate control traffic. The wireless device may identify a second subband in the unlicensed radio frequency spectrum band used to communicate data traffic. The first subband and the second subband may be different. The wireless device may reserve the first subband for a first duration of time for a plurality of wireless devices. The reservation may be based at least in part on an enhanced self-clear-to-send (self-CTS) transmitted over the first subband.

Abstract: Apparatus, methods, and computer-readable media for facilitating a cloud-based vehicle XR user experience are disclosed herein. An example method for wireless communication at a user equipment (UE) includes transmitting a request for a vehicle extended reality (XR) session. The vehicle XR session may be based on a first user XR stream including a vehicle XR component associated with a vehicle and a first user XR component associated with a first user. The first user may have an association with the vehicle. The example method also includes transmitting uplink information associated with the first user XR stream. The example method also includes receiving rendering information associated with the first user XR stream. The rendering information may be based on the uplink information.

Abstract: Methods, systems, and devices for wireless communications are described in which multiuser superposition transmission (MUST) is used to provide multiple concurrent sidelink transmissions using a same set of time and frequency resources. A transmitting user equipment (UE) may provide an indication of concurrent MUST transmissions in sidelink control information (SCI), and a receiving UE may decode one or both of a MUST base layer communication and a MUST enhancement layer communication. The base layer communication may include broadcast or groupcast transmissions to multiple UEs, and the enhancement layer communication may include a unicast transmission between the transmitting UE and a single receiving UE. The indication of concurrent transmissions may be provided in a first stage SCI, and parameters for decoding the base layer and enhancement layer transmissions may be provided in one or multiple second stage SCI transmissions.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a transmitter user equipment (UE) determines a first demodulation reference signal (DMRS) pattern for a first slot allocated for transmission over a sidelink between the transmitter UE and a receiver UE, wherein the first DMRS pattern is determined based at least on the first slot having a first slot format of two or more slot formats, and transmits, to the receiver UE, DMRS in the first slot according to the first DMRS pattern. In an aspect, the receiver UE determines the first DMRS pattern for the first slot based at least on the first slot having the first slot format, and receives, from the transmitter UE, DMRS in the first slot according to the first DMRS pattern.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for determining a Zone identifier (ID), Zone Center, and negative acknowledgement (NACK) ranges. Included are operations and means at a receiving user equipment (UE) to determine a current geographic location (GLL) of the receiving UE, and select a Zone ID based on a two-dimensional (2-D) lookup into an indexed array with the current GLL, the indexed array storing Zone data for one or more geographic Zones. The Zone data for each geographic Zone may be indexed according to geographic position, and include a Zone ID, Zone center, and one or more NACK ranges, each NACK range corresponding with a geographic Zone disposed about the geographic Zone corresponding to the Zone ID. Operations further include performing a NACK operation based on the selected Zone ID and a NACK range.

Abstract: Methods, systems, and devices for wireless communications are described. The methods include determining a sidelink message to transmit to a second user equipment (UE) over a time resource of a sidelink connection between a first UE and the second UE, encoding at least a subset of time periods of the time resource according to a configuration that is based on a switching time for the second UE for switching from a receiving mode to a transmitting mode during reception of the sidelink message during at least the subset of time periods of the time resource, and transmitting the sidelink message to the second UE using a set of time periods of the time resource that includes the subset of time periods.
