Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may reserve a transmission resource for transmitting a transmission block (TB) via a sidelink communication; reserve a retransmission mission resource for retransmitting the TB, wherein the retransmission resource is reserved such that at least one hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback occasion occurs between transmission of the TB and a first retransmission of the TB; and communicate with another UE via the sidelink communication based at least in part on the transmission and retransmission resources. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems (e.g., sidelink systems, such as vehicle-to-everything (V2X) systems), wireless devices may perform dynamic resource reservations to schedule packet transmissions (e.g., data packet transmissions). Different packets may correspond to different priority levels. To support flexible resource reservation for high priority packets, wireless devices may implement techniques for preempting lower priority reservations. For example, a wireless device may identify reservations for transmitting different packets during a same transmission time interval (TTI). The device may determine whether a first or second packet has a higher relative priority and may communicate in the V2X system during the TTI according to the relative priorities. For example, a device that reserved the TTI for the lower priority packet may refrain from transmitting the packet during the TTI, while a device that reserved the TTI for the higher priority packet may transmit the packet.

Abstract: Certain aspects of the present disclosure are generally directed to techniques for selecting a configuration for communication using vehicle to everything (V2X) type communication protocol. Certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes determining one or more parameters corresponding to quality of service (QoS) information for communication of data using a V2X communication protocol, reporting the one or more parameters by transmitting a first message, receiving a second message indicating configuration information corresponding to the communication of the data using the V2X communication protocol, and communication the data based on the configuration information.

Abstract: Aspects directed towards network-assisted sidelink scheduling are disclosed. In one example, a scheduled entity receives coverage status information of a peer user equipment (UE), and transmits a coverage status report to a network in which the coverage status report is based on the coverage status information received from the peer UE. The scheduled entity receives a resource scheduling from the network in response to transmitting the coverage status report, and establishes a sidelink communication with the peer UE based on the resource scheduling. In another example, a scheduling entity receives a coverage status report from a UE in which the coverage status report is associated with a peer UE of the UE. The scheduling entity determines a resource scheduling for the UE based on the coverage status report to facilitate a sidelink communication between the UE and the peer UE, and transmits the resource scheduling to the UE.

Abstract: An apparatus may comprise a component for communicating using a first RAT and another component for communicating using a second RAT. Overlapping communication using the two RATs may cause problems for proper reception at the apparatus. The apparatus may detect that transmission or reception of a first packet using a first RAT will overlap in time with reception of a second packet using a second RAT. The apparatus prioritizes the first packet or the second packet based at least on a relative priority of the first packet and the second packet.

Abstract: Techniques described herein provide for the efficient usage of an RF channel for PRS transmissions by performing LBT sensing for a group of one or more vehicles (e.g., V2X vehicles) in a predetermined area by using an RSU. The RSU can determine a sequence in which an order for each vehicle in the group to transmit a respective PRS is defined, and provide the sequence to the group. The RSU may further perform the LBT functionality by listening to availability on the RF channel and, when the channel becomes available, the RSU can initiate this sequence by sending an initial PRS. This LBT sensing for a group can provide far more efficient usage of the RF channel than if LBT functionality were performed by each divisional vehicle.

Abstract: Disclosed are techniques related to performing wireless sidelink communication. Originating (e.g., transmitting) and target (e.g., receiving) apparatuses may operate in a NACK-only mode. In this mode, the target apparatus only provides NACK feedbacks to transmissions that it did not receive. Lack of NACK feedback is interpreted by the originating apparatus that the transmissions were successfully received. However, the target apparatus maybe incapable of transmitting NACK for each of missed transmission. In NACK-only mode, the originating would not retransmit these missed transmissions. To address this issue, the target apparatus can transmit a multi-transmission NACK feedback to indicate that multiple transmissions were not successfully received. The multi-transmission NACK is a single feedback, and thus can enable a target apparatus with limited feedback capacity to indicate NACK for multiple transmissions.

Abstract: A method of wireless communication wireless communication by an identifier-receiving user equipment (UE) includes measuring a received signal power of multiple resource UEs. The method also includes receiving a set of identifiers from an identifier-transmitting UE. The method further includes identifying a resource used by at least one of the multiple resource UEs for a future transmission from the identifier-receiving UE based on the measured received signal power and the received set of identifiers. The method still further includes scheduling the future transmission on the at least one identified resource.

Abstract: Aspects presented herein may enable a transmitting device to encode and transmit coordination information and data in separate transport blocks, such that the transmitting device may update the coordination information without altering the transport block carrying the data. In one aspect, an apparatus encodes coordination information for sidelink resources in a first transport block. The apparatus encodes data in a second transport block. The apparatus transmits a first transmission on a PSSCH, the first transmission including the first transport block comprising coordination information and the second transport block.
