The disclosure discloses a carrier selecting method and device, an access point and a storage medium. The method includes that: an access point selects unlicensed carriers satisfying a first condition from unlicensed carriers as a first carrier set; sends a discovery signal on all unlicensed carriers in the first carrier set; and the access point receives a measurement result performed by a user equipment on all the unlicensed carriers in the first carrier set, and selects unlicensed carriers satisfying a second condition from the first carrier set based on the measurement result as carrier resources of the access point.
