1. A wireless device for wireless communications, comprising:
a processing system configured to:
establish a first wireless role and a second wireless role for the wireless device, the first wireless role being associated with upstream communications, and the second wireless role being associated with downstream communications;
perform a channel sensing procedure at the wireless device, the channel sensing procedure being common to the first wireless role and the second wireless role according to a sensing capability of the wireless device to perform the channel sensing procedure for both the first wireless role and the second wireless role as a single node;
measure, in accordance with performing the channel sensing procedure at an antenna panel of the wireless device, an energy detection value associated with a channel; and
initiate a channel occupancy time (COT) at the wireless device for at least one of the first wireless role or the second wireless role in accordance with the channel sensing procedure and a determination that the energy detection value satisfies a threshold value; and
a first interface configured to:
output signaling for transmission during the COT via at least one of the first wireless role or the second wireless role.
