Abstract: Disclosed are a method for sending control information, a base station, and a user equipment (UE). Taking implementation of the method as an example, the method comprises: a base station determining a first subframe and a second subframe, wherein the first subframe is a subframe having a control region, and the second subframe is a subframe with no control region; and the base station sending control information to a UE in the control region of the first subframe, and sending a data signal and/or an enhanced physical downlink control channel (ePDCCH) on the second subframe to the UE. By means of this solution, the first subframe has a control region, the second subframe does not have a control region, and not all the subframes have a control region; therefore, the system overhead is reduced.

Abstract: A method for virtual carrier aggregation, a base station, and a user equipment are provided. A base station receives measurement capability indication information and indication information indicating a capability of receiving data transmission that are reported by a UE. The base station selects a measurement set for the UE according to the measurement capability indication information, and sends the measurement set to the UE, where the indication information indicating the capability of receiving data transmission includes information of carriers on which the UE supports concurrent receiving of data transmission and the measurement capability indication information includes indication information indicating a capability of the UE for measuring CSI and/or indication information indicating a capability of the UE for measuring RSRP. The base station can flexibly select an activated carrier set for the UE.
