Spatial reuse of frequency channels in a WLAN
First Claim
1. A method for communication, comprising:
- arranging a first plurality of access points, comprising at least first and second access points, to communicate on a common frequency channel in a wireless local area network (WLAN) with a second plurality of mobile stations, comprising at least first and second mobile stations;
linking the access points to communicate with one another over a communication medium;
sending a message over the communication medium to at least one of the first and second access points so as to cause the first and second access points to simultaneously transmit downlink signals to the first and second mobile stations, respectively; and
transmitting the downlink signals simultaneously from the first and second access points responsively to the message.

Abstract
A method for communication includes arranging a first plurality of access points, including at least first and second access points, to communicate on a common frequency channel in a wireless local area network (WLAN) with a second plurality of mobile stations, comprising at least first and second mobile stations. The access points are linked to communicate with one another over a communication medium. A message is sent over the communication medium to at least one of the first and second access points so as to cause the first and second access points to simultaneously transmit downlink signals to the first and second mobile stations, respectively. The downlink signals are transmitted simultaneously from the first and second access points responsively to the message.

12. Apparatus for communication, comprising:
-
a first plurality of access points, comprising at least first and second access points, which are arranged to communicate on a common frequency channel in a wireless local area network (WLAN) with a second plurality of mobile stations, including at least first and second mobile stations; and
an access manager, which is coupled to send a message over a communication medium to at least one of the first and second access points so as to cause the first and second access points to simultaneously transmit downlink signals to the first and second mobile stations, respectively. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
