INFORMATION TRANSMISSION METHOD AND DEVICE

摘要

Provided are an information transmission method and device. The method includes that: a base station determines that a receiving bandwidth of first User Equipment (UE) is smaller than a system bandwidth or a component carrier accessed by the first UE is of a New Carrier Type (NCT); and the base station transmits downlink data to the first UE within the receiving bandwidth of the first UE according to a preset Radio Frame (RF), preset subframes and/or preset time-domain and frequency-domain resources. By the present invention, the problem of how to correctly receive downlink information under a downlink narrowband condition in a related art is solved, UE of different types can coexist in a system, and an application range of the system is widened.
