Title:
TRANSMISSION METHOD AND APPARATUS IN EXTENDED RANGE MODE
Document Type and Number:
WIPO Patent Application WO/2017/118253
Kind Code:
A1
Abstract:
Embodiments of the present invention provide a transmission method in an extended range mode. The method comprises: generating a physical layer protocol data unit (PPDU) in an extended range mode, wherein a conventional preamble portion of the PPDU in an extended range mode is transmitted by using bandwidth of 20 MHz; a data portion of the PPDU in an extended range mode is transmitted by using a narrowband, and the bandwidth of the narrowband transmission comprises at least one of the following parameters: 26-tone RU, 52-tone RU, 106-tone RU, and 242-tone RU. The embodiments of the present invention also provide a corresponding transmission apparatus. The method and apparatus in the embodiments of the present invention can enhance the transmission reliability of a data portion, so that the performance of portions of a PPDU in an EXT SU mode becomes more balanced, thereby ensuring the coverage area of long-distance transmission.
