DATA TRANSMISSION METHOD, APPARATUS AND SYSTEM IN HETEROGENEOUS NETWORK

摘要

Disclosed are a data transmission method, apparatus and system in a heterogeneous network. The data transmission method in a heterogeneous network comprises: a macro base station carrying control information in a subframe, transmitting the control information to a terminal by a control frequency band, and informing a micro base station of the control information; according to the control information, the micro base station carrying data information in a subframe and transmitting the data information to a terminal by a data frequency band; the control frequency band and the data frequency band are statically deployed, and the control frequency band and the data frequency band do not overlap.
