Embodiment Construction
[0078] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0079] The core of the present invention is to divide the available frequency band into at least two DRCH regions, each DRCH occupies subcarriers in at least two DRCH regions, and divide the remaining subcarriers into at least one LRCH region, and the DRCH region and the LRCH region are mutually spaced . And, at least one DRCH and at least one LRCH are set in one transmission frame, each LRCH is composed of at least one subcarrier continuous in frequency in the same LRCH region, and each DRCH is respectively composed of subcarriers distributed in at least two DRCH regions Composed of at least two subcarriers, the divided DRCH area and LRCH area are stored in the sending end and the receiving end. When the sender needs to send data, according to the size of the DR...
