Abstract
The present invention discloses a method for estimating DOA of a terminal in multiple co-frequency cells, including the steps of: A. obtaining a channel estimation result of at least one terminal expecting a calculation of DOA in an expecting co-frequency cell; B. performing a Direction-of-Arrival estimation for the expecting terminal in the expecting cell based on the channel estimation result through a DOA estimating method with a wave beam scan, a DOA estimating method with a maximum power path, or a DOA estimating method with a primary eigenvector. With the channel estimations of the multiple cells in the invention, accurate channel estimation results of the respective cells may be provided, from which the channel estimation result of the expecting terminal is selected.
