Publication number: 20240147363Abstract: A method of a low power listening mode includes announcing, by a first wireless device is operating in a low power listening mode. The first wireless device in the low power listening mode receives an initial frame having a single spatial stream and a low data rate from a second wireless device. The frame requests a frame exchange with the first wireless device. The low data rate is lower than a maximum data rate of the first wireless device. A reply to the initial frame is transmitted to the second wireless device in a single spatial stream with the low data rate. The reply acknowledges an association with the second wireless device. The first wireless device wakes from the low power listening mode to a full capacity mode, and performs a frame exchange with the second wireless device in the full capacity mode.Type: ApplicationFiled: October 30, 2023Publication date: May 2, 2024Inventors: Liwen Chu, Rui Cao, Kiseon Ryu, Hongyuan Zhang, Huizhao Wang
