Abstract: Disclosed are techniques for wireless communication. In an aspect, a first UE determine a sidelink positioning reference signal (PRS) pattern for a sidelink position estimation procedure, the sidelink PRS pattern including at least one PRS transmission occasion for each of a group of UEs on a shared communication medium, and performs one or more attempts to transmit a first PRS on one or more PRS transmission occasions associated with the first UE in accordance with the sidelink PRS pattern. In another aspects, a second UE determines the sidelink PRS pattern, and monitors a first PRS transmission occasion for receipt of a first PRS from a first UE in accordance with the sidelink PRS pattern.

Abstract: Methods, systems, and devices for wireless communications are described, in which a user equipment (UE) may communicate with one or more other UEs using sidelink communications. Multiple UEs may form a sidelink communications group and provide for sidelink groupcast communications in which an identification of a UE is determined based at least in part on a member identification of the UE within the group. Each UE in the group may determine feedback resources for acknowledgment feedback within the group based on a UE identification and a size of the group.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a remote user equipment (UE) may transmit, to a relay UE, a request for a Layer 2 relay service and a relay service code associated with the Layer 2 relay service; receive, from the relay UE, a message indicating that the relay UE accepts the Layer 2 relay service associated with the relay service code; establish a radio access signaling radio bearer (SRB) for the Layer 2 relay service using a remote UE radio access SRB configuration; and communicate via the radio access SRB. Numerous other aspects are provided.

Abstract: Some aspects described herein relate to detecting, for a first vehicle, presence of an obstacle in a driving path of a vehicle, determining, for a second vehicle, a sight stopping distance between the second vehicle and the obstacle, and transmitting, to the second vehicle and where the sight stopping distance is within a threshold, a message including a notification of the obstacle.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter user equipment (UE) may transmit, to a receiver UE, a first communication that includes a positioning reference signal (PRS) associated with the transmitter UE. The UE may transmit, to the receiver UE, a second communication that includes an information element associated with a boundary of a vehicle associated with the transmitter UE. Numerous other aspects are described.

Abstract: A ranging session between multiple user equipments (UEs) is initiated using an initial message that includes identifiers (IDs) for the initiating UE and each of one or more responder UEs. Each UE in the ranging session independently determines the timing instances of the signaling for each UE in the ranging session based on the UE IDs in the initial message. Signaling information, such as identifiers for the ranging signals, may likewise be independent determined by each UE based on the UE IDs. The order of UE IDs and number of responder UEs provided in the initial message may also be used to determine the timing instances of signaling and signaling information. The UEs, for example, may use a common multivariable deterministic function with the UE IDs as inputs to each separately derive the timing instance for itself and the other UEs in the ranging session.

Abstract: Methods, systems, and devices for wireless communications are described in which a vulnerable road user (VRU) user equipment (UE) indicates to a user whether a current position accuracy is sufficient or insufficient for approaching vehicles to determine if they present a hazard to the VRU. The position accuracy may be based on an accuracy threshold that is configured at the UE, such as by a serving base station or a road side unit (RSU). The accuracy threshold may be configured via common or dedicated signaling, through application-layer signaling, or may be pre-configured in the UE. When the VRU UE position accuracy exceeds the specified threshold for a particular interval of time, the UE may inform the user that approaching vehicles will be unable to determine their location with enough accuracy to take evasive maneuvers.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) (e.g., a vehicle, low-power sensor) may identify that the UE satisfies a set of conditions for a stationary state. The stationary state may be associated with a configuration for transmitting a position message (e.g., a basic safety message (BSM)) while the UE satisfies the stationary state. The UE may identify a periodicity at which to transmit the position message based on the UE satisfying the set of conditions for the stationary state, where the periodicity associated with a stationary state may be larger than a periodicity associated with a non-stationary state. The UE may transmit (e.g., broadcast) the position message over a sidelink in accordance with the configuration and based on identifying that the UE satisfies the set of conditions for the stationary state.

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.
