    摘要： 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.

    摘要： A method of sending data in a multiple antenna system includes the steps of generating a transmission signal by applying channel-dependent precoding to a first antenna cluster and a second antenna cluster, each comprising a plurality of antennas, wherein the channel-dependent precoding is performed by a precoding weight matrix in which a precoding weight for each of the antenna clusters has a block diagonal form and the precoding weight is represented by PxV for a number of transmission antennas P, included in each of the antenna clusters, and a number of layers V applied to each of the antenna clusters (P and V are an integer greater than 0) and sending the transmission signal.
