## Abstract

A method for a multiple BSSID environment in a wireless location area network (WLAN) is proposed. A first wireless device obtains basic service set (BSS)information of a plurality of BSSs. The first wireless device then sends a fine time measurement (FTM) frame containing the BSS information to a second wireless device. The second wireless device joins at least one of the BSS according to the BSS information.

## Claims

### Claim 1

A method comprising:
obtaining by a first wireless device being an access point (AP) a plurality of basis service set identifiers (BSSID) respectively corresponding to a plurality of BSS being at least two BBS, wherein every BSS can advertise freely;
sending by the first wireless device a fine time measurement (FTM) frame containing the plurality of BSSID to a second wireless device being a station (STA); and
the second wireless device determining to join at least one of the plurality of BSS according to the BSSID in the FTM frame.

### Claim 2 (depends on 1)

The method of claim 1, wherein the plurality of BSS are co-located BSS.

### Claim 3 (depends on 1)

The method of claim 1, wherein the FTM frame is a unicast frame.

### Claim 4 (depends on 1)

The method of claim 1, wherein the BSSID comprises MAC addresses of a plurality of co-located BSS.
