Abstract
A first wireless device determines a function of a Wake-Up (WU) Packet, selects a length of the WU Packet from a predetermined set of lengths corresponding to the function, and generates the WU packet having the selected length. The WU packet includes a Legacy preamble having a first bandwidth and a WU payload having a second bandwidth less than and included within the first bandwidth. The WU payload including an indication of the function and a control indication usable to select the length from the predetermined set of lengths corresponding to the function. The first wireless device transmits the WU packet by transmitting the Legacy preamble on the first bandwidth and then transmitting the WU payload on the second bandwidth. A second wireless device receives the WU payload and determines a length of the WU packet using the indication of the function and the control information.
