Abstract: In the future, full scenario services will put forward comprehensive requirements for 6G, and the expansion of wireless coverage capability will become one of the major challenges of 6G. The wireless coverage characteristics of different frequency bands to be used in 6G are analyzed. In addition, the empowering technologies of multiple frequency bands collaborative for full scenarios coverage extension technologies are investigated. It is believed that multiple frequency bands cooperation deployment is one of the key technologies to realize the coverage extension of full scenarios. More attention should be paid to the technologies of multiple frequency bands collaborative deployment with cost reduction and energy saving, green and efficiency, safety and reliability.
Keywords: multiple frequency bands cooperation; coverage extension; full scenarios
