Abstract: The present application provides a method for determining a CP. A STA performs channel estimation, determines a CP value according to the result of channel estimation, and sends indication information to an AP, wherein the indication information is used for indicating the CP value, so that the AP may choose a suitable CP according to the indication information. Therefore, overhead may be reduced and system throughput may be optimized.
