Claim of US Patent No. 10,172,129

1. A method for receiving data by a receiver, the method comprising:receiving a radio signal comprising a frame which includes an information region and a data region; and
demodulating the received radio signal by an OFDM (Orthogonal Frequency Division Multiplexing) scheme, wherein the frame includes a plurality of OFDM symbols in a time dimension and a plurality of subcarriers in a frequency dimension,
wherein the data region is divided into a first data region including a first type of one or more resource units and a second data region including a second type of one or more resource units,
wherein data in the first type of one or more resource units are mapped to the first data region by a first mapping scheme and data in the second type of one or more resource units are mapped to the second data region by a second mapping scheme other than the first mapping scheme, and
wherein the information region includes information to identify resource units as the first type or the second type.
