Title:
METHOD, DEVICE AND SYSTEM FOR USE IN WIRELESS COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2018/166496
Kind Code:
A1
Abstract:
The present application relates to the field of mobile communications, and relates in particular to a method for sending data in a wireless communication system. A first device generates a signal before discrete Fourier transform (DFT) transformation is performed, said signal comprising 2xM signal elements. The 2xM signal elements comprise elements from among two element groups A, B, and the elements from among the two element groups satisfy same number repetition and inverse number repetition characteristics respectively; another element group C that does not need to satisfy same number repetition/inverse number repetition characteristics is further comprised. After the 2xM signal elements undergo DFT transformation, the two element groups are orthogonal on the frequency domain. Elements in element group A and elements in element group C are reused before DFT, and an interval exists to prevent element group B or C from interfering with element group A. Since no special protection interval is needed, the utilization rate of system resources is increased.
