Abstract: A wireless device implements power saving logic for two or more wireless clients that concurrently communicate on a shared wireless channel (single channel concurrency). When one of the wireless clients transitions from power save mode to active mode (e.g., in response to a beacon signal), the power saving logic causes the other wireless client(s) to transition to active mode as well. Each wireless client ‘awakened’ in this manner transmits a NULL frame having a power management bit set to a logic ‘0’ value to an associated access point (AP), thereby indicating its active status to the associated AP. As a result, all of the wireless clients may concurrently receive buffered data from their associated APs on the shared wireless channel. If the ‘awakened’ wireless client(s) do not need to transition to active mode in response to their next received beacons, power consumption of the wireless device is advantageously reduced.
