Abstract: Methods, systems, and devices for wireless communication are described. One method for wireless communication at a first device includes receiving a multicast packet from a second device, decoding control header information in the received multicast packet, determining that a decoding procedure associated with a payload of the received multicast packet is unsuccessful and transmitting a negative acknowledgement (NACK) based at least in part on the determining. The method also includes retrieving a list of transmitter identifiers. In some cases, transmitting the NACK is based at least in part on the list of transmitter identifiers. The method further includes determining a transmitter identifier associated with the multicast packet and determining that the transmitter identifier is present in the list of transmitter identifiers.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station (BS), an indication of an access link discontinuous reception (DRX) configuration and a sidelink DRX configuration. The access link DRX configuration and the sidelink DRX configuration may synchronize access link DRX operation and sidelink DRX operation of the UE. The UE may perform access link communication with the BS based at least in part on the access link DRX configuration and/or may perform sidelink communication with another UE based at least in part on the sidelink DRX configuration. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an indication that the UE is to transition to a sidelink discontinuous reception (DRX) sleep mode. The UE may transition to the sidelink DRX sleep mode based at least in part on transmitting the indication. Numerous other aspects are provided.

Abstract: Techniques disclosed provide for enhanced V2X communications by defining information Elements (IE) for V2X messaging between V2X entities. For a transmitting vehicle that sends a V2X message to a receiving vehicle, these IEs are indicative of a detected vehicle model type detected by the transmitting vehicle of a detected vehicle; a pitch rate of the transmitting vehicle, a detected vehicle, or a detected object; a roll rate of the transmitting vehicle, a detected vehicle, or a detected object; a yaw rate of a detected vehicle, or a detected object; a pitch rate confidence; a roll rate confidence; an indication of whether a rear brake light of a detected vehicle is on; or an indication of whether a turning signal of a detected vehicle is on; or any combination thereof. With this information, the receiving vehicle is able to make more intelligent maneuvers than otherwise available through traditional V2X messaging.

Abstract: A method, a computer-readable medium, and an apparatus may include a receiving UE that is configured to receive at least a portion of a message for a service group, measure a signal strength for the message received, and determine whether to send feedback based on the signal strength measured for the message. In some aspects, a transmitting UE is configured to determine an intended range for a service group, and transmit a message for the service group based, at least in part, on the intended range. In some aspects, the transmitting UE is configured to receive HARQ feedback from at least one receiving UE, measure a signal strength for the HARQ feedback, and determine whether to resend the message based on the signal strength measured for the HARQ feedback.

Abstract: An improved manner of transmitting and receiving messages in V2X/V2V/D2D is presented in which a transmitting device determines a geographic location of the mobile transmitting device and generates a message for a service group having a group ID associated with the service group, the message comprising a first indication of a geographic area associated with the message, the geographic area based at least in part on the geographic location of the transmitting device. Then, the apparatus transmits the message to the service group, e.g., via V2X/V2V/D2D communication. A receiving device then determines its geographic location and determines whether to send a feedback for the message based on the first indication of the geographic area associated with the message and the geographic location of the receiving device.

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: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may perform a slot reservation procedure to obtain a TxOP for communicating with a second UE. The slot reservation procedure may be performed in an earliest slot in the TxOP in which the first UE has data to send to the second UE. The apparatus may transmit the data to the second UE using at least one slot in the TxOP when the slot reservation procedure is successful. In certain aspects, all remaining slots in the TxOP may be reserved for the first UE when the slot reservation procedure is successful. The apparatus may refrain from performing a subsequent slot reservation procedure in another slot in the TxOP when the slot reservation procedure is unsuccessful unless an end of transmission signal is received during the TxOP.
