A method and an apparatus for resource management, and a low-bandwidth user equipment. The method for resource management includes: determining, according to a system downlink transmission bandwidth or according to a system downlink transmission bandwidth and a maximum downlink transmission bandwidth of a low-bandwidth user equipment, a downlink transmission resource configured by a cell for the low-bandwidth user equipment. The method and apparatus for resource management proposed in the present invention are intended to solve a problem that a low-bandwidth user equipment accesses a broadband system, and enable, through resource management, a low-bandwidth user equipment and a common user equipment to coexist on a same frequency band without causing a waste of a dedicated frequency band resource.
