There is provided determining by an apparatus an access slot for communications on a first radio interface of a first and second radio interfaces. The first radio interface receives a first frame comprising at least one time related parameter for determining an access slot for communications on the first radio interface. After receiving the first frame, the apparatus is transitioned to a first operation mode, where the first radio interface radio interface is disabled. An access slot on the first radio interface may be determined based on the at least one time related parameter received before the first radio interface was disabled and based on the reception time of the frame on the second interface. In response to receiving a second frame on the second radio interface, the apparatus is transitioned to a second operational mode, where the first radio interface is enabled for transmission in the determined access slot.

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.
