Abstract: Aspects directed towards a network-assisted sidelink scheduling operation are disclosed. In one example, a scheduled entity receives a grant of resources from a scheduling entity operating according to a legacy radio access technology (RAT), and translates the grant of resources from a legacy configuration of resources to a non-legacy configuration of resources. The scheduled entity then performs a sidelink communication via the non-legacy configuration of resources. In another example, a scheduling entity operating according to a legacy RAT transmits a system information block (SIB) to a scheduled entity indicating that the scheduling entity can allocate non-legacy resources. The scheduling entity then receives a request for resources from the scheduled entity that corresponds to a non-legacy sidelink communication, and provides a grant of resources to the scheduled entity that includes a non-legacy-specific frequency for transmitting the non-legacy sidelink communication.

Abstract: Methods, systems, and devices for wireless communications are described. A first UE may transmit a sidelink request to a second UE. The sidelink request may indicate a set or a segment of the data resources. A second UE may transmit a positive sidelink response indicating that the set or the segment of resources is available for reservation, or may refrain from transmitting a positive sidelink response if the set or the segment of the data resources is unavailable for reservation. A third UE may transmit a negative sidelink response indicating that the set or the segment of the data resources is unavailable for reservation, or may refrain from transmitting a negative sidelink response if the set or the segment of the data resources is available for reservation. If the requested data resources are available, then the first UE may transmit a sidelink confirmation reserving the requested data resources.

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.
