The method for wireless resource subframe allocation comprises the following steps: allocation of the control channel based on the first RAT (Radio Access Technology) of the first control domain, which includes the OFDM symbol of the first number from the sub-frame containing multiple OFDM symbols and multiple subcarriers in the frequency domain; allocation of the control channel based on the second RAT of the second control domain including the OFDM symbol of the second number which follows said first control domain; and the allocation of a data channel in the data domain which includes the OFDM symbols positioned outside said first control domain and second control domain. This invention provides a sub-frame structure which is compatible with existing wireless communication systems. This method allows the continued use of existing control channel systems or base signal structures. The method is also capable of supporting advanced features.
