Abstract
A method for a wake-up transmitter comprises generating a wakeup signal (WUS) from a digital WUS sequence having an information symbol rate and a corresponding information symbol bandwidth, and transmitting the WUS over a frequency range having a signal bandwidth, wherein the signal bandwidth is larger than twice the information symbol rate, and wherein any frequency interval comprised in the frequency range conveys the digital WUS sequence when a width of the frequency interval is at least the information symbol bandwidth. A corresponding method for a wake-up receiver comprises receiving the WUS over the frequency range, and filtering the received WUS through a filter having a filter bandwidth for passing the information symbol bandwidth of the received WUS. Corresponding apparatuses, wake-up transmitter, wake-up receiver, communication device and computer program product are also disclosed.
