    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter device may segment a plurality of bits of a communication into a first set of bits and a second set of bits; process the first set of bits using a first processing chain and the second set of bits using a second processing chain, wherein the first set of bits is mapped to most significant bits (MSBs) of one or more symbols of a composite constellation and the second set of bits is mapped to least significant bits (LSBs) of the one or more symbols of the composite constellation, and wherein the composite constellation is formed from a plurality of lower order constellations; modulate the first set of bits and the second set of bits to generate a set of modulated symbols; and transmit the set of modulated symbols. Numerous other aspects are provided.

    Abstract: Certain aspects of the present disclosure provide techniques relating to wireless communications between vehicles. In certain aspects, a method performed by a first vehicle comprises receiving an indication from a second vehicle comprising surrounding information that is indicative of whether a first unknown vehicle is detected by the second vehicle, wherein the first vehicle and the second vehicle are able to communicate wirelessly, and wherein the first unknown vehicle is unable to communicate wirelessly with the first and the second vehicles. The method further comprises controlling movement of the first vehicle based on the indication.

    Abstract: A method of triggering a distance-based feedback transmission in a vehicle communication system includes determining an availability of the location information of a first electronic device, and transmitting sidelink control information that indicates the availability of the location information of the first electronic device. The sidelink control information includes a communication range indication or another parameter indicating the availability of the location information of the first electronic device. A receiving device receives the sidelink control information from the first electronic device, determines based on the sidelink control information that the location information of the first electronic device is unavailable, and transmits a distance-based feedback message to the first electronic device based at least in part on the sidelink control information.

    Abstract: Techniques described herein leverage existing localization sensors or V2X devices to detect one or more other vehicles that include wireless systems that can interfere with in-vehicle wireless networks. The localization sensors or V2X devices can provide information to determine a location, a heading, a speed, a size, and a type of other vehicles. This information can be used to determine a probability of network interference and allow the in-vehicle wireless networks to employ one or more techniques to mitigate the effects of the interference. The interference mitigation techniques can include increasing or decreasing transmitter power, changing a frequency or a channel of a wireless transmitter, or activating one or more additional transmitters as relays to improve reliability.

    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.
