Coordinated clear channel assessment (CCA) for wireless repeaters

A method of wireless communication performed by a first wireless communication device, the method comprising:

• transmitting, to a second wireless communication device, a control signal indicating a clear channel assessment (CCA) trigger associated with the first wireless communication device and the second wireless communication device;
• performing, based on the CCA trigger and at the first wireless communication device, a CCA;
• receiving, from the second wireless communication device, a first CCA success signal indicating that a CCA performed by the second wireless communication device has passed;
• and
• transmitting, to the second wireless communication device based on the CCA, a second CCA success signal indicating that the CCA has passed;
• and
• initiating, based on the first CCA success signal and the second CCA success signal, a channel occupancy time (COT);
• and
• communicating, via the second wireless communication device, a communication in the COT.

A first wireless communication device, comprising:

• a transceiver;
• and
• a processor in communication with the transceiver and configured to cause the transceiver to:
• receive a control signal indicating a clear channel assessment (CCA) trigger associated with the first wireless communication device and a second wireless communication device;
• perform, based on the CCA trigger and at the first wireless communication device, a CCA;
• transmit, to the second wireless communication device based on the CCA, a first CCA success signal indicating that the CCA has passed;
• receive, from the second wireless communication device, a second CCA success signal indicating that a CCA performed by the second wireless communication device has passed;
• initiate, based on the first CCA success signal and the second CCA success signal, a channel occupancy time (COT);
• and
• amplify and forward a communication in the COT to at least a receiving wireless communication device.
