Abstract: The present invention provides an information transmission method and an apparatus, so as to resolve a problem of high power consumption of a base station resulted from excessively high information overheads for transmitting an MIB by the base station. The method includes: generating, by a base station, an MIB including first bandwidth indication information and a radio frame configuration field; and sending the MIB using a time-frequency resource in a radio frame. Compared with a conventional MIB including a plurality of configuration parameters such as system bandwidth information, a frame number of a radio frame for transmitting the MIB, and PHICH configuration information, the MIB transmitted by the base station in embodiments of the present invention includes two configuration parameters: the first bandwidth indication information and the radio frame configuration field.

Abstract: A control information sending method, receiving method, and device are provided. 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 to 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: A data transceiving method includes: receiving a first reference signal transmitted on a subcarrier in a target physical resource block, and performing, according to a first mapping rule, corresponding processing on the first reference signal received from the subcarrier in the target physical resource block, where the first mapping rule defines at least mapping of the first reference signal to 10 specified subcarriers in a physical resource block, none of the 10 specified subcarriers are in a DC subcarrier candidate set, and the first reference signal includes a PCRS. In the embodiments of this application, only the 10 specified subcarriers in the physical resource block that are not used as DC subcarriers are selected to transmit the first reference signal, and no additional DC subcarrier is set. In this way, a quantity of downlink subcarriers in a system does not change dynamically.
