Scheduling apparatus and method in smart antenna system

摘要

A scheduling apparatus and method in a smart antenna system including a user where an active nulling is to be conducted are provided, in which at least one user is selected where a normal beamforming is conducted corresponding to a certain criterion; an active nulling user comprising a low channel correlation with the selected beamforming user is selected from users where an active nulling is conducted; and the normal beamforming for the selected beamforming user and the active nulling beamforming for the selected active nulling user are determined. In the system where the normal beamforming user and the active nulling user are mingled, the criterion to select the users that do not interfere with one another is suggested for the same resource to thereby efficiently utilize the resource.
