Title:
CHANNEL STATE INFORMATION SENDING METHOD AND APPARATUS, AND REFERENCE SIGNAL SENDING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/097526
Kind Code:
A1
Abstract:
The present disclosure relates to a channel state information sending method and apparatus, and a reference signal sending method and apparatus. The channel state information sending method comprises: determining a time domain resource range of a secondary cell activation specific channel state information reference signal (SAS-CSI RS); receiving the SAS-CSI RS according to the time domain resource range; and generating valid CSI according to the SAS-CSI RS and sending same to a network-side device. According to the present disclosure, it is beneficial to ensure that the period of an SAS-CSI RS is shortened without significantly increasing network overheads, such that a terminal can more quickly receive the SAS-CSI RS, thereby more quickly completing the reporting of valid CSI to complete the activation of a secondary cell.
