Abstract
Implementations of this application propose example methods and apparatuses for feeding back channel state information. In one example method applied to a wireless communications system, operations include receiving, by a user equipment, time configuration signaling and feedback configuration signaling, where the time configuration signaling is used to set a feedback time period and the feedback configuration signaling is used to configure one or more feedback cycles. The user equipment obtains and sends channel state information in one or more feedback cycles during the feedback time period.
