Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for sub-channel selection in a wireless network. In one aspect, a first message is generated at a first electronic device of a wireless network in response to a number of electronic devices of a wireless network being less than a threshold number. The first message indicates particular sub-channels of a transmission band that are to be used for a transmission in a single user (SU) mode of operation to a second electronic device of the wireless network. The method further includes sending the first message to the second electronic device. The first message indicates that a second message is to be sent to the second electronic device using the particular sub-channels. The method further includes sending the second message to the second electronic device via the transmission using the particular sub-channels.

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.
