Abstract: This disclosure provides systems, methods and apparatus, for measurement and reporting procedures associated with a sidelink positioning reference signal (SL-PRS). In one aspect, a first user equipment (UE), which may function as a sidelink anchor node, may transmit an SL-PRS to a second UE in accordance with a slot format or structure that is dedicated for SL-PRS transmissions. The first UE may select resources for the transmission of the SL-PRS via sensing and exclusion or using a set of resources that are dedicated for SL-PRS transmissions. The second UE may receive the SL-PRS and use the SL-PRS to acquire positioning information, in accordance with an observed time difference of arrival (OTDOA)-based positioning method, or may transmit a second SL-PRS to the first UE to facilitate acquisition of positioning information at the first UE, in accordance with a round-trip-time (RTT)-based positioning method.

Abstract: Methods, systems, and devices for wireless communications are described. In an example, a method for wireless communication at a first user equipment (UE) in a wireless communications system is described, including receiving, from a base station, information associated with one or more reconfigurable intelligent surfaces (RISs) in the wireless communications system. The method may also include transmitting a sensing signal to the one or more RISs based at least in part on the information and transmitting an uplink wireless communication to the base station or a second UE using the one or more RISs based at least in part on the sensing. Another method includes determining information associated with one or more RISs in the wireless communications system, transmitting, to a UE, the information associated with the RISs, and communicating with the UE via the RISs based at least in part on the information associated with the RISs.

Abstract: Methods, systems, and devices for wireless communications are described. During an operation for discovering reconfigurable surfaces, a sensing signal may be transmitted. Based on the sensing signal being transmitted, another signal may be detected at the device that transmitted the sensing signal, another device, or both. The device that detects the signal may combine the detected signal with a modulation sequence that is associated with a reconfigurable surface, where the reconfigurable surface may be assigned a set of unique modulation sequences and configured to apply a modulation sequence to received signals. Based on combining the detected signal with the modulation sequence, the device may determine whether the reconfigurable surface is present within a geographic region.

Abstract: Methods, systems, and devices for wireless communications are described. Repetitions of a reference signal may be transmitted by a first device. In some examples, the repetitions may be quasi-colocated with one another, share an antenna port, or both. The repetitions of the reference signal may arrive at a reconfigurable surface. The reconfigurable surface may apply a modulation sequence to the repetitions of the reference signal and output modulated repetitions of the reference signal in a direction based on a reflective state of the reconfigurable surface. A signal including the modulated repetitions of the reference signal may be received by a second device and combined with the modulation sequence used by the reconfigurable surface to obtain a combined signal. The combined signal may be used to determine, for the reconfigurable surface, information about a channel between the first device and the second device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a signal that is transmitted by a base station with a modulation signature associated with a reconfigurable intelligent surface (RIS) or a repeater and redirected by the RIS or the repeater using modulation that reverses the modulation signature associated with the RIS or the repeater. The UE may decode the signal, wherein the signal is decodable by the UE based at least in part on the signal being redirected by the RIS or the repeater using the modulation that reverses the modulation signature associated with the RIS or the repeater. Numerous other aspects are described.

Abstract: In an aspect, a first and second wireless node communicate a bistatic sensing request and a response to the bistatic sensing request to coordinate setup of a bistatic sensing procedure. The first wireless node transmits a set of sensing signals to one or more target objects in accordance with the bistatic sensing procedure. The second wireless node measures a set of reflections of the set of sensing signals reflected off of one or more target objects in accordance with the bistatic sensing procedure.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device may support beamformed communications, which may be implemented via reflection from environmental clusters, assistance from relays, repeaters, reconfigurable intelligence surface nodes, or some combination thereof. The communication device may partition a packet into multiple subpackets, where the communication device may assign one or more subpackets to one or more beams within a set of beams for beamformed communications. That is, the communication device may split the packet across the set of beams used for beamformed communications with another communication device. The subpackets may not be decodable independently. As such, the communication device may indicate which beams correspond to which subpackets to enable concatenation and decoding at the other communication device.

Abstract: Methods, systems, and devices for wireless communications are described. One or more anchor nodes, which may be sidelink devices, may transmit positioning reference signals (PRSs) to a wireless device, such as a user equipment (UE). The UE may select one or more PRSs to process based on respective priorities of the PRSs. At least one anchor node may transmit a priority indication including the respective priorities, or the one or more anchor nodes may transmit the PRSs according to a scrambling sequence or pattern to implicitly indicate the respective priorities. The UE may decode one or more PRSs based on the respective priorities.
