Abstract:
1. A method for configuring subchannels for an uplink data transmission at a base station in a wireless communication system, the method comprising; dividing an uplink transmission resource to PUSC (Partial Usage of SubChannel) tiles of 4 subcarriers×3 symbols; configuring sub channels to 6 PUSC tiles based on a predetermined rule; allocating a predetermined number of contiguous subchannels among the configured subchannels as subchannels for a legacy system, and allocating the remaining subchannels as subchannels for the wireless communication system, wherein subchannel rotation per slot consisting of 3 symbols is applied to the subchannels for the legacy system, wherein a subchannel rotation per subframe consisting of 6 symbols or 9 symbols is applied to the subchannels for the wireless communication system, wherein the subchannel rotation per slot is performed in accordance with Equation 1, wherein, temp wherein the subchannel rotation per subframe is performed in accordance with Equation 2, wherein, temp
