    Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to Wi-Fi systems including frame extensions in transmission frames. Lengths of frame extensions may be determined based on transmission bandwidths and transmission data rates of the frames. Lengths of frame extensions may also be determined based on an amount of useful data in a final symbol of the frame. An access point (AP) may determine frame extension lengths for use in transmitting to stations (STAs) based on reception capabilities of the STAs. An AP may determine frame extension lengths for STAs to use in transmitting frames.

    Abstract: Methods, systems, and devices for wireless communications are described that provide for dynamic resource avoidance and slot aggregation. The described techniques enable a user equipment (UE) in a vehicle-to-everything (V2X) system to select resources for varying transmission of a data packet (e.g., over multiple slots). The UE may determine a set of candidate transmission time intervals (TTIs) for transmission of the data packet based on a resource map, which may involve selecting resources that are unoccupied by other UEs as indicated by the resource map or preempting other UEs based on traffic priority or latency. The UE may transmit a reservation indication indicating resources to be reserved for subsequent transmissions (e.g., retransmission) and a UE receiving the reservation indication may update its resource map.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may generate a pseudorandom noise (PN) sequence, modulate the PN sequence based at least in part on a modulation order parameter, and transmit the PN sequence in one or more symbols prior to transmitting sidelink data. The one or more symbols used to transmit the PN sequence may be used for automatic gain control (AGC) training at a receiving device. The user equipment may then transmit the sidelink data in a plurality of symbols that are subsequent in time relative to the one or more symbols used to transmit the PN sequence, and the receiving device may process the sidelink data based on the AGC training. 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 determine a set of resource candidates in a sidelink communication system based at least in part on a set of resource assignments for a group of other UEs in the sidelink communication system. The UE may transmit a first part of a physical sidelink control channel (PSCCH) transmission. The UE may transmit a second part of the PSCCH transmission related to the first part of the PSCCH transmission to indicate a resource candidate, of the set of resource candidates, for a transmission associated with medium access control (MAC) protocol data units (PDUs) of a particular packet. Numerous other aspects are provided.
