Title:
CHANNEL ESTIMATION RESULT PROCESSING METHOD AND DEVICE, TERMINAL AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/138263
Kind Code:
A1
Abstract:
Provided are a channel estimation result processing method and device, a terminal and a storage medium, belonging to the technical field of communications. The method comprises: acquiring channel state information, the channel state information comprising first channel state information and second channel state information, the update period of the first channel state information being a first period, the update period of the second channel state information being a second period, and the first period being greater than the second period (201); within the update period of the second channel state information, acquiring, according to the first channel state information, an initial Wiener filter coefficient in the update period of the second channel state information (202); according to the initial Wiener filter coefficient and the second channel state information, acquiring a Wiener filter coefficient in the update period of the second channel state information (203); and performing, according to the Wiener filter coefficient, filtering processing on a channel estimation result. According to the described solution, the real-time calculation amount of Wiener filter coefficient calculation is reduced, and then the power consumption of the terminal is reduced.
