Title:
SIGNAL PROCESSING METHOD AND RELATED APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/077921
Kind Code:
A1
Abstract:
The present application provides a signal processing method and a related apparatus. The method is applied to a network device comprising multiple feed channels. The method comprises: receiving sounding signal information from a user equipment, the sounding signal information comprising N pieces of sub-sounding signal information received by N antennas of the network device; performing first weighting processing on the sounding signal information according to a first matrix to determine first signal information; determining a channel weight of the transmitted signal information according to the first signal information, and weighting the transmitted signal information according to the channel weight to determine N pieces of second signal information; performing second weighting processing on the N pieces of second signal information according to a second matrix to obtain N pieces of third signal information, the second matrix being an inverse matrix of the first matrix; and transmitting the corresponding third signal information by means of the N antennas of the network device. The transmission power of antennas corresponding to multiple channels is redistributed according to the uplink channel quality of the user equipment, so as to improve the coverage area of the antenna where the user equipment is located.
