WGA STA POWER SAVING

摘要

This invention relates to switching power saving modes and rescheduling communication frames for various periods of a beacon interval (BI) defined under WGA Draft Specification 0.8 for the personal basic service set (PBSS) and infrastructure BSS to achieve further power savings and other advantages. Stations can be awake during a contention-based period (CBP) if it is in active state and can schedule frames during a service period (SP) to allow the assigned receiver to transmit to the assigned initiator. Stations in a group can schedule a group address frame to be sent during the CBP and group SP of a specific periodic BI. Stations in peer-to-peer connection may directly notify its peer stations of its power saving mode and wakeup schedule. Stations of an infrastructure basic service set (BSS) can also use the same power saving mechanism as stations of a PBSS noting a difference where each BI will be an access point's (AP's) awake BI.

主权项

1. A method of saving power for a station in a personal basic service set (PBSS) or infrastructure BSS, comprising:
providing a control point having a data transfer time schedule including contention-based periods and service periods; and providing a plurality of stations in communication with the control point, the stations having an awake mode and a doze mode, the stations being configured so that the stations are in the awake during the contention-based periods.
