Abstract: A user equipment (UE) in a vehicle, or a road side unit, may broadcast an inter-vehicle message for a driving maneuver to be executed by the vehicle. The inter-vehicle message may be a coordinated driving maneuver request requiring acceptance from another vehicle or an informational message for the intended driving maneuver. The inter-vehicle message includes a temporal execution window defining a range of time during which the driving maneuver will be initiated. A temporal window defining a range of time during which the driving maneuver will be completed may also be included. A spatial window defining a range of distance for a start and/or stop location for the driving maneuver may also be completed. The vehicle may execute the driving maneuver within the temporal execution window, e.g., if a driving maneuver response is received before the expiration of the temporal execution window, and will otherwise cancel the driving maneuver.

Abstract: Independent ranging sessions that are initiated by multiple initiating user equipments (UEs) are detected and combined into a single combined ranging session to reduce overhead. The independent ranging sessions may be determined to be nearby and concurrent when a UE detects a number of ranging cycles within a predetermined time. The UE may send messages to each initiator UE indicating that the ranging sessions should be combined and the initiator UEs will terminated initiating any further ranging sessions. Combined ranging session may be initiated by the UE and may include all of the participating UEs from the independent ranging sessions. The combined ranging session continues until it is determined that one or more UEs in the combined ranging session are not receiving ranging signals from other UEs.

Abstract: Improved communications, including indication of channel occupancy time-structure information (COT-SI) for NR-U sidelink (NR-U SL) operations is disclosed. A UE may establish a current channel occupancy time (COT) on a shared communication spectrum for UE transmissions in response to a successful listen before talk (LBT) procedure. The UE may then generates a COT structure information (COT-SI) message including at least a remaining duration of the current COT and a set of time and frequency resources of the current COT. The COT-SI message may be transmitted by the UE to one or more neighboring UEs via sidelink transmission. Once the COT-SI message is sent, the UE transmits the UE transmission within the set of time and frequency resource of the current COT.

Abstract: Multiple user equipments (UEs) may initiate independent ranging sessions at nearly the same time and location and which may interfere with each other. A UE that receives multiple initial messages for ranging determines if there is temporal separation between the ranging sessions. The UE may further determine if there is geographic separation between the ranging sessions, e.g., the initiating UEs are separated. If separation is lacking, the UE separates available ranging signal properties, such as frequency bandwidth, timing instances, and identifiers, and communicates different sets of ranging signal properties to each initiating UE. The multiple ranging sessions may be performed using the different sets of ranging signal properties with less risk of interference.
