PRECODING VECTOR DETERMINATION METHOD, PRECODING PROCESSING METHOD AND BASE STATION

摘要

Provided are a precoding vector determination method, a precoding processing method and a base station. The base station comprises a plurality of transmitting antennas; an antenna failure detection module used for sending an antenna failure notification to a precoding vector determination device when monitoring that a transmitting antenna fails, the antenna failure notification comprising the serial number of the transmitting antenna which has failed; the precoding vector determination device used for updating a precoding vector according to the serial number of the transmitting antenna which has failed when receiving the antenna failure notification; and a precoding processing module used for conducting precoding processing on a transmitting signal according to the updated precoding vector so as to enable a transmitting signal to have a beam shape of a wide beam. By means of the precoding vector determination method, the precoding processing method and the base station provided in the embodiments of the present invention, a wide beam signal can still be maintained when a transmitting antenna fails, thereby eliminating the influence of an antenna failure on the wide beam signal.
