Abstract
Systems, methods, and devices for wireless communication are disclosed herein. One aspect of the disclosure provides a method of receiving a transmission from two or more wireless communication devices. The method includes receiving a first preamble transmitted by a first wireless device; simultaneously receiving a second preamble transmitted by a second wireless device; receiving a first portion of the transmission in a first section of a bandwidth, the first portion transmitted by the first wireless device including a first data section; and simultaneously receiving a second portion of the transmission in a second section of the bandwidth, the second section of the bandwidth not overlapping with the first section of the bandwidth, the second portion transmitted by the second wireless device, the second portion including a second data section.
