Abstract

Embodiments of the present invention relate to a method, device and device for determining the application time of CSI reports, the method comprising: UE receives a configuration message sent by the base station, and determines the type of PUCCH used by the secondary cell to report the CSI report according to the configuration message; the UE Receive the secondary cell activation command carrying the cell identifier sent by the base station; the UE determines the application time of the CSI report of the secondary cell corresponding to the cell identifier according to the type of PUCCH used by the secondary cell to report the CSI report and the secondary cell activation command. The method, device and device for determining the application time of the CSI report provided by the embodiments of the present invention can improve the reliability of the system.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a method, device and equipment for determining the application time of a CSI report. Background technique [0002] Carrier Aggregation (CA) means that the carrier used in the communication process is not limited to one, but simultaneously communicates on a primary carrier and several secondary carriers, and the cell division of UE aggregation with carrier aggregation function It is a primary cell and several secondary cells. [0003] In the prior art, a user equipment (User Equipment; UE for short) usually transmits channel status indications (channel status indication: CSI for short) of all cells through a physical uplink control channel (physical uplink control channel; short: PUCCH) is reported to the base station. Specifically, when the UE receives the secondary cell activation command sent by the base station in subframe N, the UE will carry the CSI o...
