In this way, the UE can wake up to perform complex control channel signal processing only when the control channel includes signals relevant to the UE, thereby conserving battery power and resources of the UE. Such techniques are particularly suited to MTC UEs, NB-IoT UEs, and/or the like, which may communicate with a network only occasionally, and which may be located in remote locations where changing or recharging a battery is difficult.
