Communicating data between an access point and multiple wireless devices over a link
First Claim
1. A method for communicating data over a network between an access point having a first and a second antenna and a first and a second mobile station, the method comprising:
- weighting a first data at said access point to transmit said first data using said first and second antennas so that said first mobile station only receives said first data; and
weighting a second data at said access point to transmit said second data using said first and second antennas so that said second mobile station only receives said second data.

Abstract
The present invention provides a method and an apparatus for communicating data over a network between a communication node, for example, an access point having a first and a second antenna and a first and a second mobile station. The method comprises weighting a first data at the access point to transmit the first data using the first and second antennas so that the first mobile station only receives the first data and weighting a second data at the access point to transmit the second data using the first and second antennas so that the second mobile station only receives the second data. A space division multiple access (SDMA) module may cause a transmission protocol to transmit the first data to the first mobile station on the downlink and transmit the second data to the second mobile station in parallel to the transmission of the first data on the downlink. In a telecommunication system, this substantially simultaneous transmission of the first and second data using a similar carrier frequency in a radio frequency communication over a wireless local area network (WLAN) may increase throughput of a downlink, for example, by a factor nominally equal to the number of antennas at an access point.

17. A communication node associated with a network to communicate data to and from a first and a second mobile station, said communication node comprising:
-
a first and a second antenna;
a controller; and
a memory storing instructions to cause said controller to weight a first data at said communication node to transmit said first data using said first and second antennas so that said first mobile station only receives said first data and weight a second data at said communication node to transmit said second data using said first and second antennas so that said second mobile station only receives said second data. - View Dependent Claims (18, 19, 20, 21)

22. A telecommunication system comprising:
-
an access point associated with a network to communicate data to and from a first and a second mobile station, said access point including;
a first and a second antenna, a controller, and a memory storing instructions to cause said controller to weight a first data at said access point to transmit said first data using said first and second antennas so that said first mobile station only receives said first data and weight a second data at said access point to transmit said second data using said first and second antennas so that said second mobile station only receives said second data. - View Dependent Claims (23, 24, 25)

26. An article comprising a computer readable storage medium storing instructions that, when executed cause a telecommunication system to:
-
enable a communication node having a first and a second antenna to associate with a network to communicate data to and from a first and a second mobile station;
weight a first data at said access point to transmit said first data using said first and second antennas so that said first mobile station only receives said first data; and
weight a second data at said access point to transmit said second data using said first and second antennas so that said second mobile station only receives said second data.
