Multiplexing of wake-up signals

A method of wirelessly providing a multiplexed wake-up packet for waking up a plurality of wireless communication receivers from a low-power state to a normal state is provided. The multiplexed wake-up packet comprises a composite of individual wake-up packets, wherein each individual wake-up packet is addressed to one of the plurality of wireless communication receivers. The method comprises determining a number N of individual wake-up packets of the multiplexed wake-up packet, determining a time offset To(n) for each of the individual wake-up packets, where n=1 . . . N, generating the multiplexed wake-up packet as a time domain multiplexed signal comprising all the N individual wake-up packets with the time offsets To(n), and transmitting the multiplexed wake-up packet. A network node is arranged to perform the method.
