<p>Various embodiments of systems and methods that provide more power save multi-poll (MPSMP) indication solutions to improve both the channel access efficiency and power saving capability. In one embodiment, for each address destination, a PSMP frame (the multi-poll frame) provides a time interval during which the client station is to receive traffic (downlink time or DLT) and the time interval during which this client station can transmit (uplink time or ULT). At any other time, such a client station may go to sleep and save power, until the next PSMP arrives. The uplink times are scheduled after the downlink times, for specific efficiency reasons. One embodiment of an MPSMP indication method enables the PSMP frame indicate whether another PSMP frame is to follow at the end of the uplink and downlink periods (or schedule) as described in the current PSMP frame, through an MPSMP indication. If the MPSMP indication is set, the client station knows to wake up immediately after the scheduled uplink and downlink times of this PSMP to receive the next PSMP.</p> |
