Abstract
The disclosure discloses a method and device for reporting channel state information aperiodically. Wherein the method comprises: collecting the channel state information reported by the UE through the configured receiving window; determining the change speed degree of the channel state of the UE according to the criterion for determining a change speed of the channel state information; deciding whether the UE needs to perform aperiodic reporting according to the mapping relationship between the change speed degree of the channel state information and a reporting period adjusting value, and determining timing for the aperiodic reporting if needed.. By the method of the disclosure, on one hand, the base station sufficiently obtains the channel state information reported by the UE, which benefits for more suitable scheduling and resource allocating for the UE; on the other hand, PUSCH resources can be used more rationally.
