Title:
CHANNEL MEASUREMENT METHOD AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/244368
Kind Code:
A1
Abstract:
Provided in the present application are a channel measurement method and a communication apparatus. The method comprises: a terminal device generates first indication information, and sends the first indication information to a network device. The first indication information is used for indicating one or a plurality of component features of a time-variant feature and a weighting coefficient of each component feature, the one or plurality of component features and the weighting coefficient of the component feature being used for characterising the time-variant feature of a channel. The time-variant feature may be determined on the basis of reference signals received multiple times by the terminal device. The terminal device can determine the changes of a channel over time on the basis of the reference signals received multiple times, quantise the time-variant channel by means of the component features and the weighting coefficients, and feed back the quantised time-variant feature of the channel to the network device, enabling the network device to understand the channel state more comprehensively.
