Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, a buffer status report associated with a one-to-many sidelink communication. The UE may receive, from the base station, one or more downlink control information (DCI) messages scheduling one or more sidelink communications, associated with one or more spatial transmission directions, for the one-to-many sidelink communication, wherein the one or more DCI messages allocate resources for each of the one or more spatial transmission directions. The UE may transmit, using the resources and in the one or more spatial transmission directions, the one or more sidelink communications for the one-to-many sidelink communication. Numerous other aspects are described.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for prioritization of sidelink-based positioning transmissions. A first UE may receive a request to initiate a sidelink positioning session with a second UE for which a sidelink positioning transmission will overlap in a time domain with communication between the first UE and a base station over a Uu access link. The first UE may transmit the sidelink positioning transmission if a first priority level of the sidelink positioning transmission is higher than a second priority level of the communication over the Uu access link. The first UE may adjust transmission of the sidelink positioning transmission if the first priority level of the sidelink positioning transmission is not higher than the second priority level of the communication over the Uu access link.

Abstract: Aspects presented herein may enable a wireless device to perform an SL ranging based on a single-sided PRS transmission. In one aspect, a first wireless device transmits one or more reference signals to at least one RIS associated with a second wireless device. The first wireless device receives one or more reflected reference signals reflected from the at least one RIS. The first wireless device calculates a signal RTT based on the one or more reference signals and the one or more reflected reference signals. In another aspect, a second wireless device transmits, to a first wireless device, information indicating a time, a duration, or a periodicity in which at least one RIS associated with the second wireless device is to be activated. The second wireless device activate the at least one RIS based on the information.

Abstract: Aspects presented herein may enable one or more wireless devices to perform a sidelink-based ranging and/or positioning with an assistance of an RIS. In one aspect, a first wireless device receives an information indicating at least a time in which at least one RIS is to be activated. The first wireless device transmits a first set of reference signals to a second wireless device via the at least one RIS. The first wireless receives a second set of reference signals transmitted from the second wireless device via the at least one RIS. The first wireless calculates a first signal RTT based on the first set of reference signals and the second set of reference signals.

Abstract: Method and apparatus for on demand assistance for sidelink communication. The apparatus receives, from a base station, an AN configuration for one or more ANs associated with the base station. The apparatus transmits, to the base station, an AR to request assistance with communication with a second UE from at least one AN associated with the base station. The apparatus receives, from the base station, a grant to schedule sidelink transmission with the second UE. The sidelink transmission with the second UE is assisted by at least one AN of the one or more ANs associated with the base station. The apparatus communicates via sidelink communication with the second UE, via the at least one AN, using allocated resources of the grant from the base station.

Abstract: Certain aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for using information related to a sidelink to optimize operation on a cellular link. According to certain aspects, using a vehicle to everything (V2X) ID of a UE (or a device associated with the UE, such as a vehicle), a base station (e.g., a gNB) may obtain information about the UE from a roadside unit (RSU). The base station may use this information (e.g., UE location, speed, or path information) to help optimize cellular communications with the UE.
