Abstract
The present invention relates to a wireless communication method and device based on a license-free band. A method for wireless communication between a base station and a user terminal comprises: receiving uplink transmission from a first type user terminal, the first type user terminal operating in a license-free mode; and switching at least one first type user terminal to a licensed mode if the evaluated decoding performance of the uplink transmission does not reach a desired level. The decoding performance is an indicator capable of more accurately reflecting the degree of resource contention, and thus can more reasonably determine the time of switching the user terminal to the licensed mode.
