Title:
COMMUNICATION METHOD AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/233500
Kind Code:
A1
Abstract:
The present application provides a communication method and device, the method includes: after the number of receiving antennas used by a terminal apparatus to receive the PDSCH sent by a network apparatus changes, the terminal apparatus determines a first CSI according to the changed number of receiving antennas, the first CSI is the CSI reported by the terminal apparatus to the network apparatus according to the result of measuring the CSI-RS with the changed number of receiving antennas; and the terminal apparatus receives the PDSCH sent by the network apparatus according to the first CSI. In the present application, after the number of receiving antennas used by the terminal apparatus changes, the network apparatus can perform downlink data scheduling with the terminal apparatus with the relatively accurate CSI, thereby improving the user experience.
