Questions about Coordinated Clear Channel Assessments: 1. How do coordinated clear channel assessments improve the efficiency of wireless communication? 2. What are the potential challenges in implementing coordinated clear channel assessments in real-world wireless networks?

1. A relevant generic question not answered by the article, with a detailed answer: How do coordinated clear channel assessments impact the overall performance of IoT devices in a shared radiofrequency band? Coordinated clear channel assessments help IoT devices avoid interference and collisions, leading to improved reliability and efficiency in communication. By coordinating channel access, these devices can optimize their transmission schedules and reduce the chances of data loss or delays.

2. Another relevant generic question, with a detailed answer: What role does channel occupancy time (COT) play in the context of coordinated clear channel assessments? Channel occupancy time (COT) is crucial for determining the availability of the channel for communication after successful clear channel assessments. By initiating communication during the COT, devices can ensure uninterrupted data transmission and minimize the risk of interference from other devices sharing the radiofrequency band.

Original Abstract Submitted

Systems, devices, and methods for performing coordinated clear channel assessments (CCAs) in a shared radiofrequency band are provided. In one aspect, a method of wireless communication performed by a first wireless communication device includes: receiving a control signal indicating a CCA trigger associated with the first wireless communication device and a second wireless communication device; performing, based on the CCA trigger, a CCA; transmitting, to the second wireless communication device based on the CCA, a first CCA success signal; receiving, from the second wireless communication device, a second CCA success signal; initiating, based on the first CCA success signal and the second CCA success signal, a channel occupancy time (COT); and amplifying and forwarding a communication in the COT.
