Title:
CHANNEL ESTIMATION METHOD AND APPARATUS, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/248329
Kind Code:
A1
Abstract:
Disclosed are a channel estimation method and apparatus, devices, and a storage medium, which relate to the technical field of communications. The method is applied to a terminal device, and comprises: using all DM-RSs on N continuous and repeatedly transmitted CORESETs to perform channel estimation, wherein N is a positive integer greater than 1, and the N repeatedly transmitted CORESETs correspond to the same frequency domain resource and/or the same precoding matrix. According to the method provided in the present embodiment, when N repeatedly transmitted CORESETs correspond to the same frequency domain resource and the same precoding matrix, a terminal device performs channel estimation by using all the DM-RSs on the N repeatedly transmitted CORESETs, such that cross-CORESET channel estimation is realized, and the accuracy of channel estimation is improved compared with only performing channel estimation in one CORESET.
