Abstract: A spectrum access method and an apparatus utilizing the same. A spectrum management apparatus includes at least one processor configured to: determine location information and antenna angle information of each of at least one secondary apparatus; in response to a request for accessing an idle spectrum of a primary apparatus, determine, according to the location information and the antenna angle information of each of the at least one secondary apparatus, a secondary apparatus to grant access to the idle spectrum; and provide, to a serving base station of each of the secondary apparatuses having the access granted, the location information and the antenna angle information of all of the secondary apparatuses having the access granted, to enable the serving base station to perform interference alignment precoding.
