Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a method of wireless communication, performed by a user equipment (UE), may include determining an inter-transmission time value for a series of transmissions to be performed by the UE; adjusting the inter-transmission time value based at least in part on a motion state associated with the UE; and performing the series of transmissions in accordance with the adjusted inter-transmission time value. Numerous other aspects are provided.

Abstract: A user equipment (UE) determines that a first transmission or first reception of a first sidelink transmission comprising inter-UE coordination information will overlap in time with a second reception or a second transmission of a second sidelink transmission. The UE transmits or receives a higher priority sidelink transmission among the first sidelink transmission comprising the inter-UE coordination information and the second sidelink transmission.

Abstract: A user device and transportation entity, such as a transport vehicle or transport server, perform information exchanges for a transportation service using Device-to-Device (D2D) communications, such as dedicated short-range communication (DSRC), a cellular Vehicle-to-Everything (C-V2X), or a 5G New Radio (NR). The information exchanges, for example, are related to, e.g., logistics and delivery of transportation services. For example, the user device may transmit a transportation request message that includes information elements, such as an identifier, a type of transport device requested, a number of users, requested destination, etc. The transportation entity may transmit a transportation response message accepting or rejecting the request. Additional messages, such as a status request and status of the transportation, as well as messages related to completing the transportation service may be exchanged.

Abstract: A user equipment (UE) establishes a unicast link with a second UE, including establishing an authentication and security establishment procedure between the first UE and the second UE. The UE establishes a security context with the second UE during the authentication and security establishment procedure. The UE starts a timer based on a status of the unicast link. The UE reestablishes the unicast link with the second UE using the security context when the unicast link is reestablished prior to expiration of the timer.

Abstract: Techniques disclosed provide for enhanced V2X communications by defining information Elements (IE) for V2X messaging between V2X entities. For a transmitting vehicle that sends a V2X message to a receiving vehicle, these IEs are indicative of a detected vehicle model type detected by the transmitting vehicle of a detected vehicle; a pitch rate of the transmitting vehicle, a detected vehicle, or a detected object; a roll rate of the transmitting vehicle, a detected vehicle, or a detected object; a yaw rate of a detected vehicle, or a detected object; a pitch rate confidence; a roll rate confidence; an indication of whether a rear brake light of a detected vehicle is on; or an indication of whether a turning signal of a detected vehicle is on; or any combination thereof. With this information, the receiving vehicle is able to make more intelligent maneuvers than otherwise available through traditional V2X messaging.

Abstract: Methods and apparatuses for managing inter-satellite handovers are provided to allow a user terminal to reduce the frequency of handovers while maintaining a sufficiently high system capacity in a non-geosynchronous satellite communication system. The method and apparatus for managing inter-satellite handovers may be implemented in a gateway, in infrastructure connected to a gateway, in a user terminal, or in a satellite.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first sidelink device may obtain an absolute time. The first sidelink device may perform a ranging session on a first sidelink connection with a second sidelink device to obtain a first propagation delay between the first sidelink device and the second sidelink device. The first device may generate a first corrected absolute time for the second sidelink device based at least in part on the absolute time and the first propagation delay such that the second sidelink device will also have the absolute time. The first sidelink device may transmit the first corrected absolute time to the second sidelink device in a first message on the first sidelink connection. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a resource exclusion configuration for applying at least a first set of resource exclusion thresholds to a selection of sidelink resources for transmitting a sidelink communication, the first set of resource exclusion thresholds being based, at least in part, on one or more modulation and coding schemes (MCSs) or an MCS index. The UE may transmit the sidelink communication in accordance with the resource exclusion configuration. Numerous other aspects are described.

Abstract: Techniques are discussed herein for transmission of location information by a user equipment (UE) to other UEs. A UE receives Satellite Positioning System (SPS) signals and determines whether the SPS signals are reliable. The UE determines a location estimate to be transmitted to other UEs using the SPS signals if the SPS signals are determined to be reliable and using non-SPS information if the SPS signals are determined to be not reliable. The location information is transmitted to other UEs in a message that includes an indication of the source of information used to generate the location estimate. A UE that receives the message may determine its location estimate based, at least in part, on the indication of the source of information, e.g., by determining whether SPS signals are reliable based, at least in part, on the indication of the source of information received in the message.

Abstract: Aspects of the disclosure provide techniques for applying redundancy mitigation rules when transmitting sensor data sharing messages. A method, performed by a sidelink user equipment (UE), includes observing, via one or more sensors, a set of objects in an environment in which the sidelink UE is operating, applying one or more redundancy mitigation rules to the set of objects, determining, from the set of objects, a number of objects to be shared with one or more other sidelink UEs after the one or more redundancy mitigation rules have been applied to the set of objects, determining, based on the determined number of objects to be shared, whether to transmit a sensor data sharing message (SDSM) to the one or more other sidelink UEs indicating the objects to be shared from the set of objects, and taking one or more actions based on the determination of whether to transmit the SDSM.
