Abstract

The invention provides a wave beam forming processing method and apparatus. The method comprises: sending to a user terminal multiple measuring signals which are shaped by wave beam forming weights at antenna oscillator grades; according to a feedback result fed back by the user terminal in accordance with the measuring signals, determining a preferable wave beam forming weight from the multiple wave beam forming weights; and according to the determined preferable wave beam forming weight, performing wave beam forming processing on communication signals. By using the method and apparatus provided by the invention, the problems of how to obtain wave beam forming weights at oscillator grades and how to obtain the wave beam forming weights at the oscillator grades in situations where measuring signal occupied resources, cost and complexity are not increased are solved, and the effects of substantially improved gain and flexibility of a wave beam forming technology are realized through obtaining wave beam forming at the oscillator grades.

Description
