  • This abstract for appeared for patent application number 18210248 Titled 'METHOD AND APPARATUS FOR RECEIVING PPDU IN WHICH DATA IS DUPLICATED IN WIRELESS LAN SYSTEM'

Simplified Explanation

The abstract describes a method and device for receiving a PPDU (Physical Protocol Data Unit) in a wireless LAN system. The receiving station (STA) receives the PPDU from a transmitting STA through a specific frequency range (band) and decodes it. The PPDU consists of a preamble and a data field. The first band is divided into two subblocks. The data field contains two types of data: the first data corresponds to the first subblock and is generated by mapping encoded data bits to a specific constellation, while the second data corresponds to the second subblock and is generated by duplicating the first data and applying a phase rotation to it.


Original Abstract Submitted

Proposed are a method and apparatus for receiving a PPDU in a wireless LAN system. In detail, a reception STA receives a PPDU from a transmission STA through a first band and decodes the PPDU. The PPDU includes a preamble and a data field. The first band includes first and second subblocks. The data field includes first data for the first subblock and second data for the second subblock. The first data is generated on the basis of data in which constellation mapping is performed on encoded data bits. The second data is generated on the basis of data obtaining by duplicating the first data and applying phase rotation thereto.
