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: The present disclosure relates to a method and a device for sending and receiving information. The method includes: determining a frame structure of a serving cell, where a radio frame corresponding to the frame structure includes at least one first special subframe, remaining subframes are downlink subframes, and the first special subframe includes symbols used for uplink transmission and downlink transmission, and a GP; and sending and receiving information in the serving cell based on the frame structure. In the technical solution, because the radio frame structure includes the first special subframe, when spectrum resources are maximally applied to downlink data service transmission, not only performance of massive MIMO is improved, but also the serving cell is enabled to work independently.
