Abstract
Embodiments of the present application disclose a clear channel assessment (CCA) method, an information receiving method, and apparatuses thereof. The CCA method comprises: sending downlink information on a first carrier, wherein the downlink information comprises first indication information, and the first indication information is used to indicate that at least one part of at least one symbol of at least one subframe is idle; and performing CCA on at least one neighboring carrier of the first carrier in at least a time of the at least one part that is idle. According to the methods and the apparatuses in the embodiments of the present application, a part of channel resources can be reserved when downlink information is transmitted on a carrier, so as to prevent interference caused by local leakage of the carrier to CCA on a neighboring carrier, thereby preventing CCA blocking between carriers.
