1. A method for determining a channel status between a first station and a second station in a wireless local area network system, comprising:
- the first station receiving a first beacon from an access point;
the first station receiving a packet outputted by the second station, the packet carrying a second beacon; and
the first station comparing the first beacon from the access point with the second beacon from the second station, to determine the channel status between the first station and the second station, wherein the channel status is used for determining whether to establish a direct link setup (DLS) between the first station and the second station, and the first station and the second station are non-access point stations.

Abstract
A method for determining a channel status between a first station and a second station in a wireless local area network system includes the first station receiving a beacon from an access point. The first station broadcasts a packet carrying the beacon. The packet provides a basis for the second station to determine the channel status between the first station and the second station.

1. A method for determining a channel status between a first station and a second station in a wireless local area network system, comprising:
-
the first station receiving a first beacon from an access point; the first station receiving a packet outputted by the second station, the packet carrying a second beacon; and the first station comparing the first beacon from the access point with the second beacon from the second station, to determine the channel status between the first station and the second station, wherein the channel status is used for determining whether to establish a direct link setup (DLS) between the first station and the second station, and the first station and the second station are non-access point stations. - View Dependent Claims (2, 3, 4, 5)

6. A wireless local area network system, comprising:
-
a plurality of stations; and at least one access point, for providing services to the plurality of stations;
wherein while a first station of the plurality of stations determines a channel status between the first station and a second station, the second station broadcasts a second packet carrying a second beacon, so that the first station is capable of comparing a first beacon with the second beacon, and determining the channel status between the first station and the second station, wherein the channel status is used for determining whether to establish a direct link setup (DLS) between the first station and the second station;wherein the second beacon is outputted by an access point corresponding to the second station, and the first beacon is outputted by an access point corresponding to the first station, and the first station and the second station are non-access point stations. - View Dependent Claims (7, 8, 9, 10)

11. A method for establishing a direct link setup (DLS) in a wireless local network system, comprising:
-
a first station and a second station starting to establish the DLS; the first station broadcasting a plurality of first packets carrying a plurality of first beacons outputted by a first access point (AP), and the second station broadcasting a plurality of second packets carrying a plurality of second beacons outputted by a second AP, to determine whether the first AP is identical to the second AP and a channel status between the first station and the second station; and the first station and the second station establishing the DLS when the first AP is identical to the second AP, and the channel status between the first station and the second station is determined as feasible to establish a connection, wherein the first station and the second station are non-access point stations. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
