Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a message indicating that a base station supports allocating resources for sidelink communications using a first radio access technology (RAT) and a second RAT that is different from the first RAT. The UE may transmit a sidelink information message to the base station using the first RAT that indicates that sidelink communications are to be performed using either the second RAT or both the first RAT and the second RAT. The UE may receive a configuration message from the base station that comprises an identifier for the sidelink communications and an indication of available sidelink resources. The UE may transmit, based at least in part on the configuration message, a request for resources within the available sidelink resources, the request indicating the identifier and a buffer status report (BSR).

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for wireless communication, and more specifically to advertising discovery information, relaying discovery information, and to the secure relay of discovery information in wireless networks. Various frame structures are provided for such transmitting and relaying of discovery information. According to certain aspects of the present disclosure, security is provided for relaying discovery information. According to certain aspects of the present disclosure, compensation may be provided to a device that relays discovery information (e.g., when the relaying results in a transaction).

Abstract: Methods, systems, and devices for wireless communications are described that improve privacy in wireless communications, such as communications by a user equipment (UE), which may in some cases be a vehicle UE. For example, various vehicle-to-everything (V2X) transmissions may be unencrypted, and a vehicle may be expected to periodically change one or more identifiers it uses for various communication services. Privacy may be enhanced, for example, via encryption key roll-over, as well as roll-over of one or more other identifiers associated with a UE that may potentially be used by an observer to track the UE. The UE may transmit a message that includes an updated lower layer identifier (e.g., a layer-2 (L2) identifier) to another UE in a V2X unicast communications link, which may trigger a change in identifiers of a set of identifiers and an updated security context. All or a portion of the message may be encrypted.

Abstract: A UE may move out of range of a network. Accordingly, the UE may use a relay node to communicate. To manage the relay node, a wireless device such as the UE may receive a relay search message from a second UE requesting a relay UE to establish a connection to the network through the relay UE. The UE may transmit a message to a base station informing the base station of the relay search message from the second UE. The UE may receive an initiate relay association procedure message from the base station, the initiate relay association procedure message informing the first UE that the first UE has been selected by the base station to initiate a relay association procedure with the second UE. The UE may transmit a relay association message to the second UE including a request to be the relay UE for the second UE.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, base stations and user equipments may use a hybrid operation mode to allocate resources in a cellular vehicle-to-everything communication system. For example, a user equipment (e.g., a vehicle) in the system may receive, from a base station, an indication that the user equipment belongs to at least one group of user equipments for group-level resource allocation, receive, from the base station, an allocation of resources including a pool of resources assigned to the at least one group of user equipments, and reserve a subset of resources of the pool of resources for communication to at least one other user equipment. This communication may be an example of a vehicle-to-everything communication over a sidelink communication channel.

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: 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: An apparatus for wireless communication is provided. The apparatus determines, through sensors of a first vehicle, second-vehicle information associated with a second vehicle. In addition, the apparatus generates at least one safety message to include the determined second-vehicle information of the second vehicle. Further, the apparatus transmits the at least one safety message. The apparatus improves the performance/benefit of V2V communications technology by transmitting BSMs for other vehicles, including non-V2V vehicles without such V2V communications technology. Accordingly V2V vehicles will be able to better assess the traffic situation.

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: Systems and methods are disclosed for sharing a discovery. The method may include receiving a first announcement from an announcement device, receiving a share instruction indicating that the received announcement is of interest to the user of the mobile device; generating discovery sharing data based on the received first announcement in response to the share instruction, transmitting the discovery sharing data to an external server, receiving an update indicator from the external server indicating that the metadata associated with the mobile device has been updated, and generating a second announcement associated with the mobile device based on the update indicator.
