METHOD AND DEVICE FOR RECEIVING PPDU ALLOCATED TO MULTI-RU, FOR CONSTELLATION MAPPED SIGNAL IN WIRELESS LAN SYSTEM

WIPO Patent Application WO/2021/029560

A1

Proposed are a method and device for receiving a PPDU allocated to a multi-RU, for a constellation mapped signal in a wireless LAN system. Particularly, a reception STA receives, from a transmission STA, a PPDU comprising a data field and decodes the data field. The data field is received via a multi-RU which is an aggregate of a first RU and a second RU. A constellation mapped signal is allocated to a data tone of the data field. The data tone comprises a first data tone of the first RU and a second data tone of the second RU. The first c first signals among constellation mapped signals are allocated to c data tones of the first RU, having the lowest frequency. One second signal which comes after the first signals among the constellation mapped signals is allocated to one data tone of the second RU, having the lowest frequency. C is defined as c=floor(a/b).
