Power saving in stations connected to a very high throughput access point

A system and method for power saving in power saving stations connected to a Very High Throughput (VHT) access point is disclosed. The access point receives triggers from power saving stations. The power saving stations are one of VHT Transmission Opportunity (TXOP) power saving stations and non-VHT TXOP power saving stations. Successively, Quality of service (QoS) requirements of buffered data for the power saving stations connected to the VHT access point is determined. In a first case, the QoS requirements of buffered data corresponding to the non-VHT TXOP power saving stations exceed the QoS requirements of the VHT TXOP power saving stations. During the first case, the VHT TXOP power saving stations are sent into a sleep state and buffered data corresponding to the non-VHT TXOP power saving stations is transmitted. In a second case, the QoS requirements of buffered data corresponding to the VHT TXOP power saving stations either exceeds or equal to the QoS requirement of buffered data corresponding to the non-VHT TXOP power saving stations. During the second case, the non-VHT TXOP power saving stations are sent into a sleep state and the buffered data corresponding to the VHT TXOP power saving stations is transmitted.
