摘要:
A wireless communications power saving method and apparatus is provided. The method includes establishing a circular buffer configured to maintain a number of most recently encountered frame delay times and waiting a frame delay time after receiving a further frame before the station enters a power save state. Frame delay time is a period equal to a largest most recently encountered frame delay period in the circular buffer. The method further determines, at a station, a dormancy time based on a number of data frames received since the station transitioned from an inactive mode to an active mode, a packet transmission rate, and a data frame time interval representing time between data frames received at the station, and causes the station to switch to a further inactive mode if a next packet is not received within the dormancy time after receipt of a previous packet.
