Abstract
A power management method. The power management method for a wireless network having a plurality of stations (STAs) comprises receiving a data frame, detecting a destination STA in accordance with the data frame, and entering a low power state if not the destination STA for a first power-save (PS) duration determined according to a network allocation vector (NAV) of each STA not the destination STA, updated with a duration information of the received data frame duration determined according to a network allocation vector (NAV) of the data frame.
Claims58
A power management method for a plurality of stations (STAs) in a Wireless Local Area Network (WLAN) comprising:
- receiving a data frame;
- detecting a destination STA in accordance with the data frame;
- and
- entering a low power state if not the destination STA for a first power-save (PS) duration determined according to a network allocation vector (NAV) of each STA not the destination STA, updated with a duration information of the received data frame.
A power management method for a plurality of stations (STAs) in a Wireless Local Area Network (WLAN) comprising:
- receiving a data frame;
- detecting a destination STA in accordance with the data frame;
- determining whether a network allocation vector (NAV) of each STA not the destination STA, updated with a duration information of the received data frame, comprises more than one ACK frame interval;
- and
- entering a low power state if not the destination STA for a first PS duration determined according to the NAV thereof.
A power management device for a plurality of stations (STAs) in a Wireless Local Area Network (WLAN), comprising:
- means for receiving a data frame;
- means for detecting a destination STA in accordance with the data frame;
- means for determining if the destination STA;
- and
- means for allowing the STAs to enter a low power state if not the destination STA for a first power-save (PS) duration determined according to a network allocation vector (NAV) of each STA not the destination STA, updated with a duration information of the received data frame.
A power management device for each of a plurality of stations (STAs) in a Wireless Local Area Network (WLAN) comprising:
- means for receiving a data frame;
- means for detecting a destination STA in accordance with the data frame;
- means for determining if the destination STA;
- means for determining whether a network allocation vector (NAV) of each STA not the destination STA, updated with a duration information of the received data frame, comprises more than one ACK frame interval;
- and
- means for allowing the STAs to enter a low power state if not the destination STA for a first PS duration determined according to the NAV thereof.
