METHOD FOR CONTROLLING TRANSMIT POWER IN WIRELESS LOCAL AREA NETWORK, CONTROLLER, AND ACCESS POINT
First Claim
1. A method for controlling a transmit power in a wireless local area network, comprising:
- determining, by a controller, a transmit power range of a radio frequency unit of a first access point (AP);
determining, by the controller, a packet reception and transmission parameter of each user link of the radio frequency unit according to packet reception and transmission information of the radio frequency unit reported by the first AP; and
configuring, by the controller, a transmit power for each user link of the radio frequency unit within the transmit power range according to the determined packet reception and transmission parameter of each user link of the radio frequency unit.

Abstract
The present invention provides a method for controlling a transmit power in a wireless local area network, a controller, and an access point, including: determining, by a controller, a transmit power range of a radio frequency unit of a first access point AP; determining, by the controller, a packet reception and transmission parameter of each user link of the radio frequency unit according to packet reception and transmission information of the radio frequency unit reported by the first AP; and configuring, by the controller, a transmit power for each user link of the radio frequency unit within the transmit power range according to the determined packet reception and transmission parameter of each user link of the radio frequency unit. Signal interference between devices in a WLAN is reduced while concurrent data transmission capability of the AP is not reduced, thereby improving system transmission performance of the WLAN.
