    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.

    Abstract: A method at a network node that is configured to simultaneously transmit and receive wireless RF signals, comprising: transmitting, from the network node, a downlink message, the downlink message having a preamble that includes channel estimation information for estimating a self-interference channel; monitoring at the network node, during an initial duration while transmitting the downlink message, for the channel estimation information, and estimating a self-interference channel based on received portions of the channel estimation information; and using the estimated self-interference channel to cancel self-interference while receiving an uplink message and simultaneously transmitting a remainder of the downlink message.

    Abstract: Methods and apparatuses for asymmetric full duplex (FD) communications. Information about an uplink (UL) transmission opportunity (TXOP), including an indication of the TXOP, is sent by an access point (AP). The AP sends a downlink (DL) transmission to a receiving station. During the TXOP, an UL transmission is received from a transmitting station. The UL transmission at least partially overlaps in time with the DL transmission. Acknowledgement of the UL transmission is sent to the transmitting station, and acknowledgement of the DL transmission is received from the receiving station, at a synchronized time.
