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 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: 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: Apparatus, methods, and computer-readable media for sidelink control information forwarding for sensing procedure are disclosed herein. An example method of wireless communication at a forwarding user equipment (UE) includes receiving, from a forwarded UE, control information, and transmitting, to a sensing UE, a forward message including the control information and information associated with the forwarded UE. An example method of wireless communication at the sensing UE includes receiving, from the forwarding UE, a forward message including the control information containing a first measurement of the control information. The example method also includes obtaining a second measurement of the forward message and determining a ratio of the second measurement to the first measurement. The example method also includes selecting a specific resource based on the ratio and whether the forwarding UE is an intended receiver for the sensing UE or the forwarding UE intends to receive from the forwarded UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may identify a collision on a victim resource based at least in part on an aggressor reservation transmitted by a second UE. The first UE may transmit, to the second UE via a sidelink feedback channel, a resource collision indication that indicates at least one of the victim resource or the aggressor reservation, wherein the resource collision indication is multiplexed on one or more resources that are useable for sidelink feedback. Numerous other aspects are provided.

Abstract: A method or apparatus for wireless communication at a wireless device. The wireless device transmits sidelink control information (SCI) indicating an aperiodic resource reservation and indicating a time gap between aperiodic resource reservations based at least in part on supplemental bits. The apparatus transmits a sidelink message based on the aperiodic resource reservation on a resource pool that supports periodic resource reservation

Abstract: Disclosed are techniques for wireless communication. In an aspect, a position estimation entity receives measurement reports that indicate a non-reciprocity condition between link directions (e.g., as part of a multi-round trip time (RTT) position estimation session). In an aspect, the position estimation entity transmits request(s) to retrieve non-reciprocity source information, which may be used in position estimation derivation (e.g., to correct for error due to the non-reciprocity). In an aspect, the request(s) may be transmitted to a target UE and/or a wireless node involved in the position estimation session (e.g., serving gNB or TRP, another UE, etc.).
