Title:
CHANNEL STATE INFORMATION REPORTING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/237700
Kind Code:
A1
Abstract:
The present application relates to the technical field of wireless communications, and provides a channel state information (CSI) reporting method and apparatus, which are used for reducing the waste of spectrum efficiency and improving the transmission performance of a PDSCH. The method comprises: a network device sending DCI to a terminal device; and the terminal device measuring a DMRS of the PDSCH according to the DCI, so as to obtain a measurement result of the DMRS, then determining CSI according to the measurement result of the DMRS and a target BLER, and sending the CSI to the network device. On the basis of the solution, a target BLER of a PDSCH is taken into consideration for reported CSI, such that a terminal device can be helped to determine relatively accurate CSI, and a network device can also adjust parameters of downlink transmission more accurately, thereby improving the network performance.
