Title:
CHANNEL CORRECTION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/192564
Kind Code:
A1
Abstract:
Provided are a channel correction method and apparatus, wherein same are applied to transceiving channel correction between every two RRUs from among multiple RRUs. The method comprises: a first RRU sending, by means of at least two antennas, correction reference signals to at least two antennae in a second RRU with a first transmitting power and a first weight vector, and combining the correction reference signals received by the second RRU into a fifth correction reference signal; and the first RRU receiving, by means of at least two antennae, the correction reference signals sent by the at least two antennae in the second RRU, and combining the correction reference signals received by the first RRU into a sixth correction reference signal, wherein the fifth correction reference signal and the sixth correction reference signal are used for calculating a correction coefficient. The technical solution provided in the present application can avoid the situation where transceiving channel correction between RRUs cannot be realized due to the fact that correction reference signals received by the RRUs have excessively low signal-to-noise ratios or an excessively high power, thereby improving the performance of the transceiving channel correction between the RRUs.
