Abstract:
Systems, methods, and devices for wireless communication are disclosed herein. One aspect of the disclosure provides a method of transmitting on a wireless communication network. The method includes transmitting to one or more first devices in a first portion of a bandwidth, the one or more first devices having a first set of capabilities, simultaneously transmitting to one or more second devices in a second portion of the bandwidth, the one or more second devices having a second set of capabilities, and wherein the transmission comprises a preamble which includes an indication for devices with the second set of capabilities to locate a frequency band in the bandwidth for symbols containing a set of transmission parameters for devices with the second set of capabilities, and where the indication is sent so as to have no substantial impact on a preamble decoding of devices with the first set of capabilities.
