Abstract

To save battery power consumption of terminals in a wireless network, e.g. a WLAN, the terminals are switched off (sleep mode) until required for receiving downlink or transmitting uplink. This is achieved by an access point using a Schedule Information Vector (SIV), transmitted to terminals in an SIV frame. The SIV contains a terminal ID, and wake up time schedule for that terminal. A terminal starts power saving mode 705 and listens for its ID following the access point beacon signal. If it is identified, it awaits the following SIV frame 730, receives and determines its schedule 732. It then sleeps until it is scheduled to receive downlink data 734, 736, 738. If the terminal is not identified 710 and has data to uplink 715, it signals to the access point 722, receives the SIV with a schedule and continues the sleep/wake cycle similarly to the reception process 724,726,728. In the access point, data for downloading to terminals is queued and an algorithm used to prioritise transmissions according to length of transmission time, shorter transmissions having priority. If necessary, the terminal may stay awake between scheduled wakings, if they are close together to save excess consumption at power down/up. The scheduling of wake up times reduces unnecessary decoding of data not intended for a terminal and also reduces contention.
