A wireless communication device (alternatively, device) includes a processor configured to support communications with other wireless communication device(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processor, among other possible circuitries, components, elements, etc. to support communications with other wireless communication device(s) and to generate and process signals for such communications. The device is configured to generate OFDM/A packet(s) that include a signal field (SIG) and a copy of that SIG (e.g., a repeat of the SIG, a repetition of the SIG, a duplicate of the SIG, etc.). In some examples, the copy of the SIG adjacently follows the SIG. Also, in some examples of a OFDM/A packet, the SIG and its copy are based on one communication protocol, standard, and/or recommended practice, and another field therein is based on another communication protocol, standard, and/or recommended practice.
