Patent ID: 10813049

Abstract:
A method and an apparatus for wireless communication are provided. In one configuration, an apparatus is configured to transmit a wake-up radio (WUR) signal, to determine to transmit a second signal within a SIFS after transmitting the WUR signal to increase medium reuse, and to transmit the second signal within the SIFS after transmitting the WUR signal based on the determination. The second signal may be a data, management, control, ACK, or CF-end frame to enable legacy devices that do not decode the WUR signal to avoid wasted airtime cause by EIFS after the WUR signal. In another configuration, the apparatus is configured to transmit a CTS-to-self frame, to determine to transmit a second signal within a SIFS after transmitting the CTS-to-self frame, and to transmit the second signal based on the determination. The second signal may be a WUR signal or an intermediate signal followed by a WUR signal.
