    Abstract: The disclosed techniques provide a method and apparatus for transmitting and receiving system information, base station, and terminal. The method of transmitting system information comprises: configuring, by a base station, a radio frame for transmitting system information in a system information window with a system information repetition pattern; and, starting, by the base station, to transmit the system information in an available radio subframe of the radio frame indicated by the system information repetition pattern, wherein if there are not enough available radio subframes for transmitting the SI one or more times in the radio frame indicated by the system information repetition pattern, the system information is repeatedly transmitted one or more times in an available radio subframe in a specified radio frame. With this technical solution, the problem in related techniques that the system information cannot be transmitted using the prior art as the number of radio subframes that system information needs to occupy increases is solved, such that regardless of a size of the system information, a suitable number of radio subframes can be selected and thereby network resources are reasonably used.

    Abstract: The embodiments of disclosure disclose a method and device for processing information. The method includes that: according to a predefined rule, subframes of a first serving cell are divided into multiple subframe groups; a management mode is configured for each of the subframe groups; and according to the management mode configured for each of the subframe groups, information on the first serving cell is processed. By means of the embodiments of the disclosure, a problem that some downlink subframes in a serving cell cannot be scheduled is solved, and different requirements of all subframes can be met, thereby improving a performance of a system, and ensuring an efficiency of data transmission.
