Abstract: Embodiments of the present invention provide a control information sending method, receiving method, and device. The control information sending method includes: determining a first subframe of a first radio frame on a first carrier, where the first subframe includes a control region; sending control information in the control region of the first subframe of the first radio frame to a user equipment, where the control information includes a PDCCH; and sending an ePDCCH in a second subframe of the first radio frame lo the user equipment. According to the embodiments of the present invention, when control information borne on an ePDCCH cannot be sent in a first radio frame, a PDCCH can still be sent to a user equipment through a control region in a first subframe, thereby achieving purposes of performing uplink/downlink scheduling for the user equipment and downlink feedback for uplink data of the user equipment.

Abstract: Embodiments of the present application provide a method for acquiring information of access resources, a terminal device, and a base station. A terminal device detects a synchronization signal of a cell to be accessed by the terminal device. The terminal device further receives a broadcast channel of the cell on a broadcast channel resource. The terminal device then determines a resource on which the cell is located according to resource indication information carried in the broadcast channel. The broadcast channel resource corresponds to an actual access resource, and the synchronization signal is detected on the actual access resource. The actual access resource is one of a plurality of candidate access resources of the cell. The resource indication information indicates a location relationship between the actual access resource and the resource on which the cell is located.
