Abstract: Methods, systems, and devices for wireless communication are described that provide for identification, on a per-PLMN basis of a type of core network associated with each PLMN in a list of networks associated with a base station. A user equipment (UE) may receive the list of networks and, based at least in part on the type(s) of core network accessible via each PLMN and a capability of the UE, initiate a connection establishment with a PLMN and associated core network. In some cases, UEs that are not capable of connections with a first type of core network (e.g., a 5G core network) may be restricted from camping on a cell or PLMN that may provide only connections with the first type of core network (e.g., a 4G core network).

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) of a group of UEs may communicate with other members of the group to provide data or other information via sidelinks. The UE may transmit a groupcast sidelink request to the base station. After receiving the sidelink request, the base station may send a sidelink grant (e.g., transmit or receive grant) in downlink control information (DCI) to the UEs in the sidelink groupcast communications group. The sidelink grant may include information for each hop such as which UEs are going to transmit or receive, the reception or transmission beams of the UEs, time and frequency resources, or the data to forward or relay. In some examples, a UE may relay information to other UEs in the sidelink groupcast communications group.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit, to a base station, a sidelink scheduling request for groupcast sidelink communications with a set of one or more UEs. The base station may determine one or more UEs of the set of UEs and time-frequency resources for groupcast sidelink communication between the first UE and the one or more UEs. The first UE may receive, from the base station, a groupcast sidelink grant that indicates time-frequency resources for groupcast sidelink communications between the first UE and one or more UEs. The first UE may transmit, via the time-frequency resources indicated by the groupcast sidelink grant, a groupcast sidelink message to the one or more UEs. The one or more UEs may also receive the sidelink grant, and may monitor the time-frequency resources for a groupcast sidelink communication from the first UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that a profile for vehicle-based sidelink communications supports packet duplication using a set of carrier frequencies. The UE may transmit a message to a base station that identifies the profile and the set of carrier frequencies. The UE may receive a configuration message from the base station that identifies a packet duplication configuration. The UE may transmit, based on the packet duplication configuration, a request to the base station for resources to perform the vehicle-based sidelink communications, the request comprising one or more buffer status report (BSRs), wherein each BSR identifies a carrier frequency for the BSR and a logical channel group identifier that identifies the BSR as being for packet duplication.

Abstract: Methods, systems, and devices for wireless communications are described. In one example, a method includes receiving broadcast information from a base station that identifies types of resources for vehicle-based sidelink communications that are supported by the base station and transmitting a request to the base station for resource scheduling information to perform a vehicle-based sidelink communication based on the broadcast information. In some cases, the request includes an indication of a type of resources for the vehicle-based sidelink communication supported by the base station and a quality of service (QoS) metric associated with the vehicle-based sidelink communication. In some cases, the method further includes receiving, in response to the request, a response from the base station that comprises the resource scheduling information to perform the vehicle-based sidelink communication.

Abstract: Various aspects of the disclosure relate to sharing vehicle sensor information. In some aspects, a requestor (e.g., a first vehicle) may transmit a request for vehicle sensor information. A responder (e.g., a second vehicle) may then respond with information sensed by the responder. For example, a requestor may unicast a vehicle-to-anything (V2X) message that requests a particular responder to share specified sensor information. As another example, a requestor may broadcast a vehicle-to-anything (V2X) message that requests any responder that meets a response criterion (or response criteria) to share specified sensor information.

Abstract: Aspects of the disclosure relate to devices for coordinating resource usage. A scheduled device receives a downlink control information (DCI) grant from a scheduling device, the DCI grant identifying scheduled resources for communicating data. The scheduled device decides whether the DCI grant is acceptable for communicating the data and sends an acknowledgement to the scheduling device based on the decision and information associated with the DCI grant. The scheduled device communicates the data via the scheduled resources when the DCI grant is decided to be acceptable. A scheduling device transmits the DCI grant to the scheduled device and receives the acknowledgement from the scheduled device based on the information associated with the DCI grant. The acknowledgement indicates whether the DCI grant is acceptable for communicating the data. The scheduling device communicates the data via scheduled resources identified in the DCI grant when the DCI grant is indicated to be acceptable.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) that is configured to transmit a message to a neighboring UE via multiple formats, identify a service parameter indicative of a format to be used for the message. The UE may convey information indicating the service parameter from a first layer of the UE to a second layer of the UE, wherein the first layer is an upper layer with respect to the second layer. The UE may generate, by the second layer and based at least in part on the information, the message in the format for communicating with the neighboring UE. Other aspects, embodiments, and features are claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may initiate a radio resource control (RRC) layer signaling procedure between the UE and a target UE, include an upper layer signaling message in an RRC message based in part on the RRC layer signaling procedure, and transmit the RRC message including the upper layer signaling message to the target UE. Alternatively, upper layer signaling messages may be transmitted separately before or after the RRC layer signaling procedure.

Abstract: Methods, systems, and devices for wireless communications are described that provide a mechanism for a wireless node to identify resources that are controlled by a different wireless node in the wireless backhaul communications network and in some cases autonomously transmit certain transmissions using resources of the different wireless node. A first wireless node may receive signaling that indicates whether such transmissions may be autonomously transmitted via configuration information or a flag provided in signaling to the first wireless node. The first wireless node may in some cases determine that autonomous transmissions are enabled based on a type of communication or node that provides the information for the transmissions from the first wireless node. In some cases, a priority associated with the transmissions may be used to determine whether autonomous transmissions are enabled.
