Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE), may receive, at a processing layer of the UE, sets of discontinuous reception (DRX) cycle parameters from a corresponding set of applications at an application layer of the UE. The UE may determine, based on the sets of DRX parameters, a common DRX cycle to satisfy each of the sets of applications. The UE may transmit the common DRX cycle to one or more layers in the user plane protocol stack of the UE. A base station may also receive a request, from the UE, for a set of DRX cycle parameters that satisfies the common DRX cycle of the UE. The base station may transmit an indication of the set of DRX parameters, and receive, from the UE, a confirmation of a DRX cycle associated with the set of DRX cycle parameters.

Abstract: Aspects relate to sidelink positioning using second stage sidelink control information (SCI-2). A first wireless communication device (e.g., first UE) may transmit SCI-2 including a sidelink positioning establishment message to establish a sidelink positioning session with at least a second wireless communication device (e.g., a second UE). Each of the first UE and second UE may then transmit positioning reference signals (PRSs) and generate and transmit sidelink positioning information based on the PRSs during the sidelink positioning session. The sidelink positioning information may further be transmitted via SCI-2.

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: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may estimate one or more channel availability parameter values. The UE may then select, based on a co-channel configuration indicating a relationship between channel availability parameter values and patterns of sidelink resources, a pattern of sidelink resources (e.g., LTE resources) on which to transmit NR packets. In some examples, a special UE may receive individual or aggregated reports of channel availability parameter values. The special UE may select a pattern of sidelink resources (e.g., LTE resources) on which one of the reporting UEs is permitted to transmit NR packets, and may transmit a message activating the pattern of sidelink resources to the reporting UE. The reporting UE may then use the activated sidelink LTE resources for transmitting NR packets according to the indicated pattern.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) of a group of UEs may receive, from a group member of the group of UEs, traffic information including a transmission schedule associated with traffic of the group member UE. The UE may determine a discontinuous reception configuration for the group of UEs based at least in part on the transmission schedule. The discontinuous reception configuration may include a discontinuous reception schedule for the group of UEs. The UE may transmit, to the group of UEs, the discontinuous reception configuration.

Abstract: An improved manner of transmitting and receiving messages in sidelink communication is presented in which a wireless device receives sidelink control information (SCI) that indicates a zone ID associated with a sidelink message. The wireless device determines a location of the wireless device and determines whether to send feedback for the sidelink message based, at least in part, on the zone ID associated with the sidelink message and the location of the wireless device. The feedback may include hybrid automatic repeat request (HARQ) feedback, and the sidelink message may include a groupcast message. The wireless device may further receive an indication of an intended range in the SCI and may determine whether to send the feedback based on a combination of the zone ID and the intended range for the sidelink message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may encapsulate, into a link layer sidelink management message, upper layer signaling for managing a direct communication connection with a second UE. The first UE may transmit, to the second UE, the link layer sidelink management message including the upper layer signaling. The second UE may selectively transmit, to the first UE, a link layer sidelink response message based at least in part on a content of the upper layer signaling in the link layer sidelink management message. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for handling slice information for a roaming user equipment (UE). In some cases, the UE may send, to a network entity, a request with an information element (IE) indicating one or more protocol data unit (PDU) sessions to be transferred from a source network to a target network. After receiving, from the network entity, a response with an IE identifying one or more of the PDU sessions allowed to be transferred to the target network and indicating slice information applicable in the target network for the one or more PDU sessions allowed to be transferred, the UE may update slice information for each of the PDU sessions allowed to be transferred based on the IE in the response.

Abstract: Methods, systems, and devices for ranging are described. A multi-phase distributed ranging technique includes transmitting and receiving vehicle information messages during a first time interval, where the vehicle information messages include at least a vehicle identifier and resource information. The multi-phase technique further includes transmitting and receiving ranging signals during a second time interval, and determining times of arrival of received ranging signals. A centralized ranging technique includes receiving resource assignments from an access point, transmitting ranging signals according to the resource assignments, and determining times of arrival of received ranging signals.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may establish a sidelink connection with a second UE, where the sidelink connection is associated with a plurality of flows. The first UE may determine, based on monitoring each flow of the plurality of flows, a radio link status of the sidelink connection. The first UE may transmit, based on the determining, a non-access stratum layer message to the second UE based at least on the radio link status of the sidelink connection.
