Resource units for wide band transmission in a wireless network

Embodiments of the present invention provide an apparatus and method for WLAN transmission over 320 MHz channels that use encoding and modulation schemes of existing 160 MHz tone plans defined in the IEEE 802.11ax standard. For example, 320MHz transmissions on a contiguous 320MHz channel or a non-co...

Summary:Embodiments of the present invention provide an apparatus and method for WLAN transmission over 320 MHz channels that use encoding and modulation schemes of existing 160 MHz tone plans defined in the IEEE 802.11ax standard. For example, 320MHz transmissions on a contiguous 320MHz channel or a non-contiguous 160MHz+160MHz channel can be performed using a 320MHz PPDU, or a 160MHz+160MHz PPDU, and the 320MHz/160 MHz+160 MHz PPDU can be defined using the 160MHz tone plan according to the IEEE 802.11ax standard. The existing tone plan of the IEEE 802.11ax standard is modified as described herein according to embodiments of the present invention. According to some embodiment, the 160MHz tone plan can be repurposed to support multi-link aggregation including 80MHz+240MHz transmission, or 160MHz+160MHz transmission using two or more links.
