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: Certain aspects provide a method for wireless communication by a first user-equipment (UE). The method generally includes determining a first configuration for communication with a second UE of one or more discovery messages on a sidelink channel and a second configuration for data communication with the second UE on the sidelink channel, wherein the first configuration is different than the second configuration, and communicating with the second UE in accordance with at least one of the first configuration or the second configuration.

Abstract: Aspects relate to techniques for communication between wireless communication devices using ranging channel information obtained by each of the wireless communication devices. For example, a first wireless communication device may obtain first monostatic ranging channel information based on reflected ranging signals received in response to transmission of a ranging signal. In addition, the first wireless communication device may receive ranging feedback information from a second wireless communication device associated with second monostatic ranging channel information obtained by the second wireless communication device. The first wireless communication device may then determine bistatic channel information from the first monostatic ranging channel information and the ranging feedback information and transmit a message to the second wireless communication device based on the bistatic channel information.

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.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a method of wireless communication performed by a first pedestrian user equipment (PUE) includes performing a ranging operation to a set of UEs, the set including at least a second PUE, and providing ranging data to a third entity, the third entity comprising a vehicle user equipment (VUE) or a road-side unit (RSU). The set of UEs may be randomly selected or selected using a selection algorithm. The set of UEs may be selected by the PUE or by the third entity. The ranging data may include the location of the first PUE, and may include a report on the battery status of the first PUE. The third entity may use the ranging data to update estimated positions of the first PUE and the set of UEs.

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.
