1. A method for power saving in a wireless communication network, the method comprising:

negotiating with an access point, by a wireless network interface of a first client station, a first component channel of an operating channel via which the first client station is to receive wakeup frames from the access point, the operating channel comprising at least four component channels;

receiving, at a wakeup radio of the first client station, a wakeup packet from the access point, the wakeup packet spanning the operating channel, wherein one or more of the component channels within the operating channel are punctured so that the access point does not transmit the wakeup packet in the one or more component channels of the operating channel that are punctured, and wherein the wakeup packet includes a first wakeup frame for the first client station in the first component channel and one or more respective second wakeup frames for one or more second client stations in one or more respective second component channels; and

processing, by the wakeup radio of the first client station, the first wakeup frame received in the first component channel.
