Abstract
Techniques pertaining to 80 MHz distributed-tone resource unit (dRU) tone plan-based dRU designs for wide distribution bandwidths 160 MHz and 320 MHz in wireless communications are described. An apparatus (e.g., station (STA)) generates a distributed-tone resource unit (dRU) using a 80 MHz dRU tone plan as a basic building block. The apparatus then performs a wireless communication in a 160 MHz or 320 MHz distribution bandwidth with the dRU.
