Abstract: A method, a computer-readable medium, and an apparatus are provided. The apparatus communicates with a second apparatus, including transmitting or receiving a first transmission. The apparatus receives information about the second UE from a sensor at the first UE and/or from a BSM. The apparatus determines whether the first apparatus and the second apparatus are in a LOS condition based on a correlation of the information with one or more of a channel estimation, PMI feedback, or RI feedback. The apparatus may adapt a transmission parameter for a second transmission based on a predicted location of the first apparatus or the second apparatus. The transmission parameter may include at least one of a modulation, a code rate, a DMRS density, a precoder, a CSI-RS transmission periodicity or a feedback rate.

Abstract: Aspects of the present disclosure provide synchronization techniques for user equipment (UEs) that may be otherwise unable to support sidelink communication a synchronized UE and may have also lost global navigation satellite system (GNSS) and/or Evolved Node Base Stations (eNBs) as a synchronization source. In such instance, the unsynchronized UE may utilize reference signals (RS) from the data packets received from other UEs to track the timing and perform autonomous timing adjustments based thereon for synchronized packet transmission or reception.

Abstract: Methods, apparatuses, and computer-readable mediums for wireless communication by a user equipment (UE) includes transmitting a packet on a first resource, determining one or more repetition resources on which to send one or more redundancy versions of the packet, wherein the one or more repetition resources are at a time subsequent to the first resource, transmitting repetition resource information identifying the one or more repetition resources to one or more neighboring UEs, and transmitting the one or more redundancy versions of the packet on respective ones of the one or more repetition resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a selection window after an arrival of a packet. The selection window may be selected based at least in part on a delay budget associated with the packet. The UE may determine, based at least in part on the selection window, a control exclusion zone value. The UE may perform, based at least in part on the control exclusion zone value, a resource selection associated with determining available resources for transmitting a set of transmissions associated with the packet. 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 receive one or more sidelink communications on a sidelink between the UE and another UE. The UE may transmit one or more hybrid automatic repeat request (HARQ) feedback communications, associated with the one or more sidelink communications, on the sidelink and in a HARQ feedback resource included in a multi-slot feedback reporting period. The HARQ feedback resource may include a set of negative acknowledgement (NACK) resources or the set of NACK resources and a set of acknowledgement (ACK) resources. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to mechanisms for code block segmentation in a wireless communication network (e.g., a sidelink network). In some examples, a wireless communication device may reserve resources across two or more slots on a carrier for transmission of a transport block. The wireless communication device may then select code block parameters for segmenting the transport block into a plurality of encoded code blocks such that each encoded code bock is fully contained within a single slot. In some examples, the code block parameters may include a number of encoded code blocks and a respective size of each of the encoded code blocks.

Abstract: Certain aspects of the present disclosure provide techniques for half-duplex handling with system-wide feedback resources. Embodiments include determining, for a first feedback resource corresponding to a first time period, that the wireless node has a scheduled feedback transmission and a scheduled feedback reception on shared frequency resources. Embodiments include selecting one of the scheduled feedback transmission or the scheduled feedback reception based on a rule. Embodiments include using the feedback resource to perform the selected one of the scheduled feedback transmission or the scheduled feedback reception.

Abstract: Aspects described herein relate to managing coexistence of multiple radio access technology (RAT) components in a device. Information related to an upcoming time period can be sent to a first radio access technology (RAT) component from a second RAT component. The first RAT component can select a resource to transmit a first RAT packet to minimize collision with the upcoming time period of the second RAT.

Abstract: Aspects described herein relate to transmitting a direct link synchronization signal for wireless communications. A user equipment (UE) may determine a synchronization signal priority level. The UE may determine a number of resources in a synchronization signal period on which to transmit a direct link synchronization signal block from the UE based on the synchronization signal priority level. The UE may transmit the direct link synchronization signal block on the number of resources.

Abstract: Methods, systems, computer-readable media, and apparatuses for vehicle emergency vehicle-to-anything (V2X) notification based on sensor fusion are presented. In some embodiments, a vehicle may receive an indication of an issue or impairment of the vehicle or an occupant of the vehicle, including the driver. Using information from sensors within the vehicle, an on-board processor may determine the nature of the impairment. Information about the nature of the impairment may then be transmitted, using V2X notification, to neighboring vehicles and/or an infrastructure entity (e.g., a base station, a roadside unit, a radio tower, and/or a central application server). The neighboring vehicles may then negotiate using V2X communication with the impaired vehicle and the other neighboring vehicles and/or be directed by the infrastructure entity to proceed using a negotiated course of action that accounts for the nature of the impairment in the impaired vehicle.
