Claim Text:
1. A data sending method in a heterogeneous network, comprising: carrying, by a macro base station (BS), control information in a subframe, sending the control information to a user equipment, UE, on a control-frequency band, wherein all Orthogonal Frequency Division Multiplexing (OFDM) symbols at the macro BS are configured to carry the control information; and notifying, by the macro base station, a low power node (LPN) of the control information, wherein the control-frequency band and a data-frequency band are configured statically, wherein the data-frequency band is used by the LNP to send data information to the UE according to the control information, wherein all OFDM symbols at the LPN are configured to carry the data information, and wherein the control-frequency band and the data-frequency band are on different bandwidth portions of the same carrier; or the control-frequency band and the data-frequency band are on different carriers.
