Transmit power control algorithms for sources and sinks in a multi-link session

A memory medium configured to store programming instructions executable to:

• instruct a source device to adjust its output transmission power according to:
• transmit data by the source device to a plurality of sink devices over a wireless Radio Frequency (RF) link;
• and
• receive acknowledgement messages, by the source device, from the plurality of sink devices over the wireless RF link, wherein the acknowledgement messages are transmitted in response to receiving the data transmitted from the source device;
• determine, by the source device, whether acknowledgment messages have been received from each of the plurality of sink devices;
• increase an output transmission power of the source device, if it is determined that acknowledgment messages were not received from all of the plurality of sink devices;
• and
• decrease an output transmission power of the source device, if it is determined that acknowledgment messages were received from all of the plurality of sink device.

A wireless device comprising:

• a transmit path comprising a power amplifier (PA) for transmitting signals over a wireless Radio Frequency (RF) link wherein the transmit path is used to transmit data from a source device to a plurality of remote wireless devices;
• a receive path configured to receive signals over the wireless RF link;
• and
• a power control block configured to adjust an output power level of the PA;
• wherein the wireless device is configured to communicate with the plurality of remote wireless devices over the wireless RF link through the transmit path and the receive path, to transmit data to the plurality of remote wireless devices and to receive a one or more acknowledgement message from the plurality of remote wireless devices;
• wherein the acknowledgement messages are transmitted by the plurality of remote devices in response to receiving the data transmitted from the wireless device;
• and
• wherein the power control block is configured to increase the output transmission power level of the wireless device, if it is determined that acknowledgment messages were not received from all of the plurality of remote devices;
• and
• wherein the power control block is further configured to decrease the output transmission power of the source device, if it is determined that acknowledgment messages were received from all of the plurality of remote devices.
