Abstract: Systems and methods for emulating Full Duplex (FD) transmissions between two or more devices by way of out-of-band Full Duplex communication, also known as Frequency Division Duplexing-Full Duplex (FDD-FD) communication. FD communication refers to a wireless communication device being able to transmit and receive communications at the same time. In out-of-band FD communication, a first communication channel is used for transmitting a first communication in one direction and a second communication channel is used for simultaneously transmitting a second communication in the reverse direction. Examples relate to management frames for managing channel availability and channel selection for implementing the out-of-band FD communication. An example wi-fi management frame includes an identification of both the first channel for the wireless communication device to transmit on, and the second channel for the wireless communication device to simultaneously receive on.

Abstract: Systems and methods for generating a control signal for automatic wireless network version detection of a transmission. The control signal enables a receiver to detect the wireless network version detection of the transmission, so that the proper wireless network version is used for interpreting signaling information and decoding of the payload of the transmission. In some examples, the control signal is within a preamble of the transmission. The wireless network version can be an IEEE 802.11 version, such as proposed IEEE 802.11be. The control signal is compatible with legacy systems and can indicate the legacy signaling information by way of a Legacy Signal (SIG) (L-SIG) symbol. In some examples, the control signal can indicate the wireless network version by using an identifier symbol which is generated from at least part of, but is not identical to, the L-SIG symbol.
