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: Methods and techniques are described for supporting location services for a user equipment (UE) using a location server and service based interfaces (SBIs) and SBI service operations in a Fifth Generation wireless network. The location server may be, e.g., a Location Management Function (LMF). The LMF may be in either a serving Public Land Mobile Network (PLMN) for a UE or in a Home PLMN for a roaming UE. The LMF may receive a location service request for the UE using an SBI and may communicate with another entity in the network, through a second entity and using an SBI, to obtain location information for the UE measured by the other entity. The LMF may determine a location for the UE based on the location information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a relay user equipment may establish a sidelink unicast link with a remote UE via a sidelink signaling interface; receive, from a network entity, configuration information comprising at least one of: remote UE link identifier information associated with the sidelink unicast link for a relay service, an RLC channel mapping between the one or more RLC channels of the sidelink unicast link and the link with the network entity, or data routing information associated with the relay service; configure the one or more RLC channels for the sidelink unicast link and the link with the network entity based at least in part on the configuration information; and relay communications between the remote UE and the network entity based at least in part on the configuration information. Numerous other aspects are provided.

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: Some aspects provide a method for wireless communication by a first wireless device. The method generally includes selecting, from a resource pool allocated for sidelink data transmission from a second wireless device to the first wireless device, a subset of the resource pool for the sidelink data transmission. The method generally includes transmitting an indication to the second wireless device of the selected subset of the resource pool. The method generally includes monitoring the subset of the resource pool for the sidelink data transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station (BS), an indication of an access link discontinuous reception (DRX) configuration and a sidelink DRX configuration. The access link DRX configuration and the sidelink DRX configuration may synchronize access link DRX operation and sidelink DRX operation of the UE. The UE may perform access link communication with the BS based at least in part on the access link DRX configuration and/or may perform sidelink communication with another UE based at least in part on the sidelink DRX configuration. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an indication that the UE is to transition to a sidelink discontinuous reception (DRX) sleep mode. The UE may transition to the sidelink DRX sleep mode based at least in part on transmitting the indication. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may identify a first set of resources for an access link communication between the first UE and a base station. The UE may identify a second set of resources for a sidelink communication between the first UE and a second UE. The UE may identify a scheduling conflict between the first set of resources for the access link communication and the second set of resources for the sidelink communication. The UE may drop at least a portion of the first set of resources for the access link communication or the second set of resources for the sidelink communication based at least in part on the identification of the scheduling conflict and a prioritization rule. Numerous other aspects are provided.

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: A method, a computer-readable medium, and an apparatus may include a receiving UE that is configured to receive at least a portion of a message for a service group, measure a signal strength for the message received, and determine whether to send feedback based on the signal strength measured for the message. In some aspects, a transmitting UE is configured to determine an intended range for a service group, and transmit a message for the service group based, at least in part, on the intended range. In some aspects, the transmitting UE is configured to receive HARQ feedback from at least one receiving UE, measure a signal strength for the HARQ feedback, and determine whether to resend the message based on the signal strength measured for the HARQ feedback.
