20140169250 | WiMax Enhanced Sleep Mode - Enhancements are provided to lower power consumption in a wireless communication device. A traffic indicator message is designated to be positioned at or near a first burst to be transmitted to a subscriber station. Further, a clock signal provided to a decoder in the subscriber station has a variable frequency, the frequency being chosen based on the nature of the data to be decoded. Data needing immediate decoding is processed with a high speed clock. Other data are processed with a lower speed clock to reduce power consumption. Also, control information that is demodulated when the subscriber station is in sleep mode is batch processed when the subscriber station becomes active again. | 06-19-2014 |
