Abstract
Methods, systems, and devices for wireless communications are described in which a user equipment (UE) using a first radio access technology (RAT) may transmit a channel reservation preamble of a second RAT (e.g., a Wi-Fi preamble) that provides an indication to devices of the second RAT that the UE has obtained a shared channel for a channel occupancy time (COT). The UE may determine a start time of the channel reservation preamble relative to a start time of a first symbol of a transmission slot based at least in part on a time duration of the first symbol. The channel reservation preamble may reserve multiple slots or a single slot. A UE transmitting on two or more sub-channels may transmit a preamble on one of the sub-channels or on each of the sub-channels.
