Abstract
In a method for low-power wireless communication, a primary connectivity radio transmits a wake-up radio configuration request to a wireless device and receives a wireless wake-up configuration response comprising a wake-up identifier for distance aware wake-up notification mode. A companion low-power wake-up radio receives from the wireless device, a wireless wake-up radio measurement reference for which it measures a receive signal strength, determines it as a reference level, and associates the reference level with the wake-up identifier. The wake-up radio then receives from the wireless device, a wake-up frame that includes a received wake-up identifier. The wake-up radio determines that the received wake-up identifier compares with the wake-up identifier associated with the reference level. The wake-up radio measures a receive signal strength of the wireless wake-up frame and wakes-up the primary connectivity radio, if the receive signal strength of the wireless wake-up frame is above the reference level.
