Abstract

The invention provides an information reporting method, a base station and user equipment. The method comprises the following steps: sending an MAC (medium access control) carrier activation signaling for activating the first component carrier, wherein the MAC carrier activation signaling comprises CQI (channel quality indication) information, and the CQI information is used for indicating the user equipment to report the non-periodic CQI information of the second component carrier of the user equipment so that the user equipment triggers to report the non-periodic CQI information of the second component carrier of the user equipment after receiving the MAC carrier activation signaling. By using the information reporting method, base station and user equipment provided by the embodiment of the invention, the problem of relatively slow reporting of CQI information of the activated component carrier can be solved.

Description

Technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to an information reporting method, a base station, and user equipment. Background technique [0002] In the uplink direction of the wireless communication system, the user equipment needs to feed back channel quality indication CQI (Channel Quality Indication) information to the base station. The base station can know the downlink channel quality status perceived by the user equipment through the CQI information fed back by the user equipment, so as to help the base station perform frequency selective scheduling. [0003] The CQI information of the user equipment is reported to the base station through PUCCH (Physical Uplink Control Channel, physical uplink control channel) or PUSCH (Physical Uplink Shared Channel, physical uplink shared channel). [0004] In carrier aggregation technology, the spectrum of two or more CCs (Component Carrier component...
