Abstract: Aspects of the disclosure relate to mechanisms for encoding and transmitting an encoded channel indication that indicates a starting sub-channel and a number of sub-channels for a transmission over a vehicle-to-everything (V2X) carrier. The encoded channel indicator may be transmitted within at least one symbol of a listen-before-talk (LBT) section of a slot.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems (e.g., vehicle-to-everything (V2X) systems), a source user equipment (UE) may multicast a data packet to surrounding UEs. In some cases, a receiving UE may fail to receive the transmission due to blocking, shadowing, or interference. The receiving UE may multicast a message requesting retransmission of the packet. Any surrounding UEs that successfully received the data packet from the source UE and the relay request message from the receiving UE may determine whether to relay the packet. Determining whether to relay the packet may be based on a reference signal received power (RSRP) threshold, available resources, a distance to the blocked UE, or some combination thereof. In some examples, the receiving UE may successfully receive the relayed packet from the relay UE even if a path between the receiving UE and the original source UE is blocked.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a first user equipment (UE) performs a limited beam sweep of one or more transmit beams on a second frequency band in an estimated direction from the first UE to the second UE, wherein the estimated direction is based on one or more parameters received over a previously established signaling radio bearer (SRB) on a first frequency band and/or a device-to-device discovery procedure performed on the first frequency band, receives, over the SRB, a confirmation that a data radio bearer (DRB) has been established on the second frequency band with at least one transmit beam of the one or more transmit beams, and sends, to the second UE, a data flow over the DRB on the second frequency band using the at least one transmit beam.

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: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive one or more transmissions from one or more UEs in a first slot, including a first transmission from a second UE. The first UE may receive the first transmission using a receiver configured with a first gain and may decode the first transmission. The UE may determine a correspondence (e.g., a temporal correlation) between the first slot and a second slot and may configure the receiver with a second gain at the beginning of the second slot based on the correspondence. The UE may determine that a total received signal power in the second slot is associated with the total received signal power in the first slot. The UE may decode one or more transmissions in the second slot based on the receiver having the second gain at the beginning of the slot.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE), e.g., a vehicle in a group of platooning vehicles configured for wireless communications, may identify a travel direction of the group of platooning vehicles. The UE may identify a set of time-frequency radio resources allocated to the travel direction. The UE may perform inter-vehicle communications with one or more neighboring vehicles of the group of platooning vehicles using the set of time-frequency radio resources.

Abstract: Methods, apparatuses, and computer-readable mediums for wireless communication include re-coding a first coded packet into a second coded packet, wherein the second coded packet includes less coded bits and has a higher modulation order than the first packet, generating one or more redundant versions of the second packet, and transmitting the second packet and the one or more redundant versions of the second packet at different times to a receiving user equipment.

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: Aspects relate to limiting the number of missed reservations by a wireless communication device, such as a vehicle-to-everything (V2X) device. The wireless communication device may calculate a missed reservation metric associated with one or more missed reservations missed by the wireless communication device. The wireless communication device may then limit additional reservations when the missed reservation metric exceeds a missed reservation limit.

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.
