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 user equipment (UE) may identify that a sidelink communication is to be transmitted by the UE prior to a next sensing results sharing opportunity associated with a collaborative sensing schedule that is associated with resource selection for sidelink communications for a group of UEs that includes the UE. The UE may select resources for the sidelink communication. The UE may transmit the sidelink communication using the resources. Numerous other aspects are described.

Abstract: An apparatus, e.g., a UE, is disclosed. The apparatus may transmit, to a serving cell, UE capability information for performing L1/L2 measurements of at least one target RS received from a non-serving cell and reporting measurement information. The apparatus may receive, based on the transmitted UE capability information, a configuration including a TCI state scheduling the UE to receive the at least one target RS from the non-serving cell based on at least one source RS associated with the TCI state, and to perform the L1/L2 measurements of the at least one target RS. The number of RS reported in the measurement report may be based on at least one of a UE capability, an indication received from the serving cell, a pre-configuration, or an indication received from the serving cell in which the indication is within the UE capability.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, a UE capability report that indicates which transmission configuration indicator (TCI) state types the UE is able to support when using a sounding reference signal (SRS) as a source reference signal for a TCI state. The UE may receive, from the base station, a configuration for one or more TCI state types for the SRS as the source reference signal based at least in part on transmitting the UE capability report. Numerous other aspects are described.
