setting network allocation vectors of at least the m busy channels of the n channels according to l time durations, wherein 1≤l≤n,
wherein the terminal performs synchronous communication through the n channels,
wherein setting the network allocation vectors of the at least the m busy channels of the n channels according to the l time durations comprises:
determining a longest time duration in the l time durations; and
setting a network allocation vector of each channel of the n channels according to the longest time duration.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the terminal performs asynchronous communication through the n channels.

### Claim 3 (depends on 2)
