Embodiments of the present invention relate to a multi-channel access method and apparatus. A first device performs data transmission with a second device on a first reserved channel, and the method includes: identifying, by the first device, whether a non-reserved channel except the first reserved channel is in an idle state; triggering, by the first device, a backoff procedure if the non-reserved channel is in an idle state; sending, by the first device, a channel reservation frame on the non-reserved channel after the backoff procedure ends, where the channel reservation frame is used to enable the first device to use the non-reserved channel as a second reserved channel; and performing, by the first device, data transmission with the second device on the first reserved channel and the second reserved channel. |
