摘要： Methods and systems for waking up an electronic device having a wake-up receiver circuit. A signal is transmitted, carrying a wake-up frame (WUF) including a protocol data unit (PDU). A wake-up sequence is inserted in a portion ahead of the PDU. The wake-up sequence is used by the electronic device for detection of the WUF and identification of the intended recipient. The WUF also includes a wake-up identifier (WUID) that is used by the electronic device to authenticate the WUF.

摘要： A method, apparatus and system for transmitting control information in a header of a physical protocol data unit (PPDU), such as an IEEE 802.11 compliant PPDU. Embodiments include indicating control features in an EDMG PPDU for Wireless LAN communications. The method and system may include overloading at least one bit of a Scrambler Initialization Field in the PPDU header (e.g. the PHY header) to convey control information, as well as to be used to initialise the scrambler shift register. The same header bits are thus used for both purposes. Examples of control information include a primary channel, channel width or MIMO configuration to be used in further communication.

摘要： Methods and systems for waking up a wireless receiving device having a wake-up radio (WUR) circuit. A low-power wake-up signal is transmitted, comprising a wake-up frame (WUF) including having a portion that is subjected to spectrum spreading and transmitted using a single carrier. The wake-up signal is processed by the receiving using non-coherent detection.

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 providing a low-rate data signal. Received input data bits are Manchester modulated onto successive multicarrier symbols in the time domain. Each multicarrier symbol includes orthogonal sub-carrier and a null sub-carrier. A stored waveform can be retrieved to code the sub-carriers. The successive multicarrier symbols are up-converted to a carrier frequency to provide the low-rate data signal, and the low-rate data signal is transmitted.
