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.

Abstract: Independent ranging sessions that are initiated by multiple initiating user equipments (UEs) are monitored and combined into a single combined ranging session to reduce overhead. A UE monitors a first set of ranging sessions initiated by a first initiator UE, which include pre-ranging messages identifying UEs in the first set of ranging sessions, and monitors a second set of ranging sessions initiated by a second initiator UE, which include pre-ranging messages identifying UEs in the second set of ranging sessions. The UE initiates a third set of ranging sessions by broadcasting pre-ranging messages identifying UEs in the third set of ranging sessions that comprises the UEs in the first set of ranging sessions and the UEs in the second set of ranging sessions. The original initiator UEs, upon receiving the pre-ranging messages initiating the third set of ranging sessions, terminate the initiation of their ranging sessions.

Abstract: The apparatus (e.g., a first radar device) may be configured to receive a second radar waveform from a second radar device; determine a transmission timing difference between a transmission time of a first radar waveform and a transmission time of the second radar waveform, where the first radar waveform may be transmitted by the first radar device; and generate a radar point cloud associated with one or more targets based on the received second radar waveform and the determined transmission timing difference. A second radar device may be configured to transmit a second radar waveform; receive, from one or more targets, one or more reflections of the second radar waveform; and transmit, to a first radar device, cooperative radar sensing information regarding the received one or more reflections.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE via a sidelink interface, one or more keep-alive request messages. The UE may perform a link recovery with the second UE based at least in part on the one or more keep-alive request messages satisfying a condition. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first sidelink user equipment (UE) may detect a second frequency range (FR2) radio link or beam failure between the first sidelink UE and a second sidelink UE. The first sidelink UE may transmit, to the second sidelink UE, an indication of the FR2 radio link or beam failure based at least in part on a first frequency range (FR1) radio resource control (RRC) connection between the first sidelink UE and the second sidelink UE.

Abstract: A UE includes: a wireless transceiver; a directional, reflection-based ranging system configured to determine directions and distances between the UE and reflectors; and a processor configured to: obtain, from the ranging system (1) a first direction, between the UE and a particular reflector, and (2) a first distance, between the UE and the particular reflector, corresponding to the first direction; determine, based on a positioning reference signal (PRS) received by the wireless transceiver from a PRS source (3) a second direction, corresponding to an angle of arrival of the PRS at the UE, and (4) a second distance, traveled by the PRS from the PRS source to the UE, corresponding to the second direction; and determine whether the second distance is a line-of-sight distance between the UE and the PRS source based on the first direction, the first distance, the second direction, and the second distance.

Abstract: Apparatus, methods, and computer-readable media for facilitating improvement in sensing for unicast sidelink communication are disclosed herein. An example method for wireless communication at a first user equipment (UE) includes receiving, from a second UE over a sidelink channel, a first transmission comprising sidelink control information (SCI). In some aspects, the SCI indicates a resource reservation of the second UE. The method includes obtaining measurements of the first transmission and determining whether the measurements exceed a reference threshold. The method includes determining whether the SCI includes an indication that the second UE is following a first resource recommendation of a third UE that is an intended receiver of the second UE when the measurements exceed the reference threshold. The method also includes ignoring the resource reservation of the second UE when the SCI includes the indication that the UE is following the first resource recommendation of the third UE.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for non-standalone sidelink discovery. A user equipment (UE) may be capable to operate in two or more separate frequency ranges. In one of the separate frequency ranges, sidelink discovery may require a burdensome overhead due to the nature of beam forming at high frequency ranges. Communications in another lower frequency range may signal to aid the discovery, thus reducing the overhead. For example, the UEs may use the low frequency communication to perform a beam alignment and discovery with lower signaling overhead. In addition, the UE may signal the capability in a first frequency range using signatures or indications in a communication in a second frequency range. For example, the UE may use FR2 to signal FR1 capability, such as using beam pilots as signatures to indicate FR1 capability.

Abstract: A UE may receive, from a base station/TRP, a configuration for a beam pair including an UL beam and a DL beam and transmit a RACH message via the UL beam while receiving DL information via the DL beam. The UE and/or the base station/TRP may be configured to operate in a FD mode. In aspects, the UE may transmit a RACH preamble based on a first mode of transmission. After a threshold time delay measured from the transmission of the RACH preamble, the UE may retransmit the RACH preamble based on a second mode of transmission. The second mode of transmission may be a same mode of transmission or a different mode of transmission from the first mode of transmission. Each mode of transmission may be based on one or more of TDM, FDM, or SDM.
