    Abstract: Embodiments provide a channel contention method and apparatus. The channel contention apparatus belongs to a basic service set (BSS). The BSS includes an access point (AP) and at least one first station (STA). Both the AP and the at least one first STA participate in channel contention. The apparatus is the AP or any first STA. The apparatus includes a sensing module configured to sense a channel. The apparatus also includes a contention module configured to contend for the channel. The AP centrally performs control and scheduling so that all of at least one network device in the BSS can transmit data by using the channel.

    Abstract: This application discloses a communication method. The method includes: comparing, by a second transmit end device, a second bandwidth carrying at least one second service transmission and a first bandwidth, wherein the first bandwidth is used by a first transmit end device within a first specified time period on an unlicensed frequency band to complete first service transmission, the at least one second service transmission started in a remaining time period of the first specified time period after the first service transmission is completed; performing channel listening on the second bandwidth based on a result of the comparison; and performing, by the second transmit end device, the second service transmission on the second bandwidth if the second bandwidth is found to be in an idle state. In addition, a corresponding transmit end device is disclosed. This application discloses a channel listening mechanism applicable to a flexible-bandwidth scenario.
