Title:
INFORMATION FEEDBACK METHOD AND APPARATUS, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/004718
Kind Code:
A1
Abstract:
The present application relates to the technical field of communications, and provides an information feedback method and apparatus, a device, and a storage medium. The method comprises: a terminal device sends first feedback information to a network device, the first feedback information being obtained based on a reference MCS, wherein the reference MCS corresponds to a first PDSCH, or the reference MCS is configured by the network device, or the reference MCS is predefined by a communication protocol. Embodiments of the present application help to reduce the calculation delay and power consumption for the terminal device to obtain information related to a channel state, and also save CSI-RS resources, so that the communication system has more resources to transmit downlink data, and the network capacity is improved.
