1. An apparatus comprising:
at least one processor, and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:
receive, from at least one terminal device by a wake-up receiver of the apparatus, at least one enhanced wake-up signal, wherein, based on transmitting the enhanced wake-up signal, the at least one terminal sets up a timer (T) indicating a time period within which a response to the enhanced wake-up signal is to be received from the wake-up receiver;
decide, by the wake-up receiver, to wake-up the apparatus from a network energy saving mode in response to:
a number of enhanced wake-up signals received before expiry of a wait timer (T1) being above a threshold number, wherein the wait timer (T1) is shorter than the timer (T),
at least one unenhanced wake-up signal being received from the at least one terminal device before expiry of the wait timer (T1),
further enhanced wake-up signals being received before the expiry of the wait timer (T1), and
a user terminal buffer status flag being turned on in the enhanced wake-up signal; and
transmit, to the at least one terminal device, a response to the at least one enhanced wake-up signal, wherein the response indicates that the apparatus is active.
