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.

Abstract: This document discloses a solution for enabling overlapping transmissions in a wireless network. An apparatus may be arranged to detect a response to a frame, the response transmitted from a first device as addressed to a second device different from the apparatus and comprising a first value indicating a received signal strength between the first device and the second device. The apparatus may determine a second value indicating a received signal strength of the response in the apparatus and cause transmission of a frame that overlaps with a transmission between the first device and the second device only if the second value in proportion to the first value is below a determined threshold.

Abstract: A transmitter is configured to set a counter to a starting value, sense whether a channel is busy or idle and to update the counter value during sensing. When there is data to be transmitted, the transmitter is configured to determine, based on at least the counter value at a transmit opportunity and a duration the channel has been sensed idle before the transmit opportunity, whether to transmit the data or to continue the sensing the channel to a next transmit opportunity without resetting the counter value to the starting value.
