A method includes receiving, by an apparatus, a signaling element containing an indication whether there are buffered individually addressed frames for at least one device within a group of devices; determining, by the apparatus, whether the apparatus belongs to a group for which there are no buffered individually addressed frames, based on the indication; and if the apparatus belongs to a group for which there are no buffered individually addressed frames, entering a lower power state without waiting to receive a next signaling element.
