Abstract

See full text

This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Some implementations more specifically relate to tone mapping techniques and physical layer convergence protocol (PLCP) protocol data unit (PPDU) designs that support duplicate (or “DUP mode”) transmissions with channel puncturing. In some implementations, a wireless communication device may transmit a PPDU carrying user data over a wireless channel excluding one or more punctured subchannels, where the user data is transmitted in a DUP mode. As such, the user data may be mapped to a number (N) of tones spanning a first portion of the wireless channel and a duplicate copy of the user data may be mapped to N tones spanning a second portion of the wireless channel.
