Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The apparatus may receive from a second device a first data packet in one or more receiving slots of a time division duplex frame that includes a plurality of slots. The apparatus may determine whether the first data packet is received incorrectly. The apparatus may wait until the end of the one or more receiving slots and may transmit to the second device a first NACK in a NACK feedback symbol in a configured slot after the end of the one or more receiving slots in response to determining that the first data packet was not received correctly.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may utilize priority levels associated with packets or transmissions to determine whether to transmit feedback for a received transmission. The UE may compare priority levels between a transmission subject to a feedback condition and a transmission scheduled to be received when the feedback is scheduled to be transmitted to determine whether to send the feedback. The UE may communicate with the transmitting device according to the comparison and the determining. The UE may determine signal conditions causing a NAK and determine to send the NAK based on the signal conditions.

Abstract: The present disclosure provides techniques for communicating feedback for data transmissions over a sidelink in a wireless communication system. For example, devices and methods are provided for wireless communication by a first wireless device. In one example, the first wireless device determines that only one of either feedback can be transmitted to a second wireless device or a second communication can be communicated, wherein the feedback is indicative of whether a data transmission is successfully decoded, and based on that prioritizes one of the feedback or the second communication. In another example, the first wireless device determines that only one of either feedback can be received from the second wireless device or a second communication can be communicated, wherein the feedback is indicative of whether the data transmission is successfully decoded by the second wireless device, and based on that prioritizes one of the feedback or the second communication.

Abstract: Methods, systems, and devices for ranging are described. A multi-phase distributed ranging technique includes transmitting and receiving vehicle information messages during a first time interval, where the vehicle information messages include at least a vehicle identifier and resource information. The multi-phase technique further includes transmitting and receiving ranging signals during a second time interval, and determining times of arrival of received ranging signals. A centralized ranging technique includes receiving resource assignments from an access point, transmitting ranging signals according to the resource assignments, and determining times of arrival of received ranging signals.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may establish a sidelink connection with a second UE, where the sidelink connection is associated with a plurality of flows. The first UE may determine, based on monitoring each flow of the plurality of flows, a radio link status of the sidelink connection. The first UE may transmit, based on the determining, a non-access stratum layer message to the second UE based at least on the radio link status of the sidelink connection.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may receive situational information for a second wireless device over a first communication link between the first wireless device and the second wireless device and situational information for a third wireless device over a second communication link between the first wireless device and the third wireless device. The first wireless device may transmit message with guidance information to the second wireless device on behalf of the third wireless device and based on the second wireless device and the third wireless device having an event likelihood above a threshold. The event likelihood may be based on the situational information for the second wireless device and the situational information for the third wireless device.

Abstract: Certain aspects of the present disclosure provide techniques for transmitting system information on sidelink. A method that may be performed by a first user equipment (UE) includes receiving first system information from a second UE; determining, based on one or more first parameters, to receive second system information from the second UE; receiving the second system information in a sidelink system information block (S-SIB) from the second UE; and communicating with the second UE via sidelink resources determined based on the first system information and the second system information.

Abstract: Methods, systems, and devices for wireless communications are described. Examples may include a receiving wireless device located in a first geographic zone receiving multiple signals from one or more transmitting wireless devices. The receiving wireless device may determine based on the received signals that the one or more transmitting devices are located in a second geographic zone. The receiving wireless device may determine configured transmit power information for each of the signals received from the transmitting wireless devices located in the second geographic zone. The receiving wireless device may estimate a path loss of wireless communications between the first geographic zone and the second geographic zone based on the configured transmit powers received in the signals. The receiving wireless device may communicate within the second geographic location based on the estimated path loss between the first geographic region and the second geographic region.
