Title:
CHANNEL STATE INFORMATION PHASE CORRECTION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/119949
Kind Code:
A1
Abstract:
Provided are a channel state information phase correction method and apparatus, relating to the technical field of wireless communications. On the one hand, in the embodiments of the present application, the method comprises: receiving data signals transmitted on various carriers at the same moment; then collecting, according to the data signals, original CSI phase information on the various carriers of various antennas so as to obtain an original CSI phase measurement matrix; and finally, calculating, according to the original CSI phase measurement matrix and a pre-set phase correction algorithm, a corrected CSI phase measurement matrix, thereby improving the accuracy of the corrected CSI phase information, and enabling same to have a greater use value. Therefore, the CSI phase information corrected by the technical solution provided by the embodiments of the present application can be applied to the wireless positioning technology.
