Method of selecting antennas and transmitting data in multi-input multi-output wireless local area network environments

Abstract

In a Multiple-Input Multiple-Output (MIMO) wireless local area network (WLAN) system, a method is provided for selecting at least one antenna from a plurality of antennas and transmitting a data frame from a station to an access point via the selected antenna or antennas. A method for transmitting data from a plurality of stations to an access point in the MIMO WLAN system includes detecting a channel status of a channel from the access point to each transmitting antenna of the station, selecting at least one transmitting antenna from among the station's transmitting antennas based on the detected channel status, and transmitting a data frame from the station to the access point via the selected transmitting antenna or antennas.

1 . A method for transmitting a signal by a first transceiver in a Multiple-Input Multiple-Output (MIMO) system, the method comprising:
 receiving information related to a number of transmitting antennas of a first transceiver for a signal transmission, the information being transmitted from a second transceiver;   selecting at least one transmitting antenna set from among transmitting antenna sets based on the information; and   transmitting a signal to the second transceiver via the selected at least one transmitting antenna set.   
     
     
         2 . A method for receiving a signal by a second transceiver in a Multiple-Input Multiple-Output (MIMO) system, the method comprising:
 determining information related to a number of transmitting antennas of a first transceiver for a signal transmission;   transmitting the information to the first transceiver; and   receiving a signal transmitted from at least one selected transmitting antenna set from among transmitting antenna sets in the first transceiver based on the information.
