Title:
JOINT CHANNEL ESTIMATION METHOD AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/266862
Kind Code:
A1
Abstract:
Proposed are a joint channel estimation method and an apparatus therefor, which belong to the technical field of wireless communication. The method comprises: determining the maximum duration length of a terminal device (101), and determining a reporting strategy for the maximum duration length (102); determining an actual time window length according to the reporting strategy and the maximum duration length (103); and performing joint channel estimation processing according to the actual time window length (104). Thus, an actual time window length may be determined according to the maximum duration length of a terminal device and a reporting strategy, so that the terminal device may perform joint channel estimation processing according to the actual time window length.
