Abstract: Embodiments provide a method, a user equipment, and a base station for transmitting information. The method includes receiving a downlink assignment sent by a base station. The downlink assignment includes a trigger flag that is used to indicate a trigger state of aperiodic channel state information (CSI). An uplink resource used to send the aperiodic CSI is determined. The aperiodic CSI to the base station is sent on the uplink resource according to the trigger flag.

Abstract: Embodiments of the present invention provide a method, where a UE determines that uplink control information to be sent to an eNB in an uplink subframe includes channel state information (CSI) and a scheduling request (SR). The UE further determines a first uplink channel resource for sending the CSI and the SR to the eNB. The first uplink channel resource has an SR sending format and is used to send the CSI. The UE then sends the CSI and the SR to the eNB on the first uplink channel resource in the uplink subframe.

The detecting method includes: determining a candidate resource set within virtual downlink resources of a current cell. The candidate resource set can include at least one candidate resource carrying a common control channel of the current cell. A detection is performed on at least one candidate resource in the candidate resource set, so as to acquire the common control channel of the current cell. In the embodiments of the present invention, a selection range of resources for transmitting a common control channel is extended, so that inter-cell interference of the common control channel can be coordinated, and a detection performance of the common control channel can be improved.
