US Patent 10924995 Wake-up radio roaming

This disclosure is directed to controlling a wake-up radio (WUR) in a wireless station side client device (STA-device). In one example, after the STA-device has received negotiation parameters from a wireless access point (AP) to establish a wireless association as a network connection between the STA-device and the AP. The PCR may be disabled in favor of the WUR. The WUR, which may use less power than the PCR, may then monitor for Beacon Frames (e.g., in the disclosed beacon loop) and Discovery Frames (e.g., in the disclosed discovery loop). Based on a state machine, that may be implemented as computer instructions executed by a hardware processor of the STA-device. Generally, the STA-device may use the WUR and state machine implementation to determine a proper time to re-enable the PCR for communication with the AP.
