A method for processing a network allocation vector, NAV, comprising: terminating receiving of a first radio frame when it is determined that a target receiving station of the first radio frame being received is not a first station; and updating an NAV of the first station or maintaining the NAV of the first station unchanged according to a remaining duration of the first radio frame and a first transmission opportunity duration carried in the first radio frame, wherein the remaining duration of the first radio frame is transmission time used for transmitting a remaining part of the first radio frame after the receiving of the first radio frame is terminated; characterized in that, the updating the NAV of the first station or maintaining the NAV of the first station unchanged according to the remaining duration of the first radio frame and the first transmission opportunity duration carried in the first radio frame comprises: determining whether a sum of the remaining duration of the first radio frame and the first transmission opportunity duration is greater than the NAV; in response to determining that the sum is greater than the NAV, updating the NAV of the first station by using the sum of the remaining duration of the first radio frame and the first transmission opportunity duration; and in response to determining that the sum is not greater than the NAV, maintaining the NAV of the first station unchanged; or using a predetermined variable to store the first transmission opportunity duration and using the remaining duration of the first radio frame to update a radio frame duration timer; and when a value of the radio frame duration timer is zero, determining whether the predetermined variable is greater than a value of the NAV; in response to determining that the predetermined variable is greater than the value of the NAV, using the predetermined variable to update the NAV; in response to determining that the predetermined variable is less than or equal to the NAV, maintaining the NAV of the first station unchanged. terminating receiving of a first radio frame when it is determined that a target receiving station of the first radio frame being received is not a first station; and updating an NAV of the first station or maintaining the NAV of the first station unchanged according to a remaining duration of the first radio frame and a first transmission opportunity duration carried in the first radio frame, wherein the remaining duration of the first radio frame is transmission time used for transmitting a remaining part of the first radio frame after the receiving of the first radio frame is terminated; characterized in that, the updating the NAV of the first station or maintaining the NAV of the first station unchanged according to the remaining duration of the first radio frame and the first transmission opportunity duration carried in the first radio frame comprises: determining whether a sum of the remaining duration of the first radio frame and the first transmission opportunity duration is greater than the NAV; in response to determining that the sum is greater than the NAV, updating the NAV of the first station by using the sum of the remaining duration of the first radio frame and the first transmission opportunity duration; and in response to determining that the sum is not greater than the NAV, maintaining the NAV of the first station unchanged; or using a predetermined variable to store the first transmission opportunity duration and using the remaining duration of the first radio frame to update a radio frame duration timer; and when a value of the radio frame duration timer is zero, determining whether the predetermined variable is greater than a value of the NAV; in response to determining that the predetermined variable is greater than the value of the NAV, using the predetermined variable to update the NAV; in response to determining that the predetermined variable is less than or equal to the NAV, maintaining the NAV of the first station unchanged.
