    摘要: 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.

    摘要: 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.

    摘要: Methods and systems for waking up a wireless receiving stations having wake-up radio (WUR) circuits. A method of providing a wake-up signal in a communications channel for a plurality of receiving stations, comprising: generating a plurality of series of waveform coded symbols, each series being incorporated into a respective wake-up-radio (WUR) frame that is intended for a respective receiving station and has a respective predefined bandwidth; combining the respective WUR frames into a multiband WUR data unit having a bandwidth that is greater than a sum of the predefined bandwidths of the wake-up radio frames; transmitting a wake-up signal including the multiband WUR data unit in the communications channel.
