Abstract
Methods, systems, and devices for wireless communications are described. A relay device operating in an unlicensed radio frequency (RF) spectrum band may receive a channel occupancy time (COT) indication from a first wireless device via a control message, a preamble sequence, or an on-off energy pattern, among other examples. Upon receiving the COT indication from the first wireless device, the relay device may perform a listen before talk (LBT) procedure. If the LBT procedure is successful, the relay device may relay signals between the first wireless device and the second wireless device. Otherwise, the relay device may refrain from relaying signals between the first wireless device and the second wireless device. The described techniques may enable the relay device to operate with greater efficiency and reduced power consumption. The described techniques may also improve the reliability of communications between the first wireless device and the second wireless device.
