Power save mechanism for ap communicating with multi-link operation (mlo) client devices

An access point (AP) comprising:

• a non-transitory machine-readable storage medium storing instructions;
• and
• a processing resource coupled to the non-transitory machine-readable storage medium, wherein the processing resource is configured to execute one or more of the instructions to:
• transmit a first set of data packets, over a plurality of wireless links, to a client device operating in a Multi-Link Operation (MLO) mode;
• identify a first set of wireless links of the plurality of wireless links over which the client device is unresponsive to the first set of data packets and a second set of wireless of the plurality of wireless links over which the client device is responsive to the first set of data packets;
• retransmit the first set of data packets over the first set of wireless links;
• transmit a second set of data packets over the second set of wireless links;
• and
• configure the client device in a dummy power-save state for the first set of wireless links in response to determining that a first count of retransmissions over the first set of wireless links has reached a first threshold value.

A method comprising:

• determining, by an access point (AP), whether a client device operating in a Multi-Link Operation (MLO) mode is configured in a dummy power-save state for a first set of wireless links of a plurality of wireless links, wherein the first set of wireless links comprises wireless links over which the client device has not acknowledged receipt of a first set of data packets sent to the client device from the AP;
• transmitting, by the AP, one or more status check messages to the client device over the first set of wireless links within a predefined duration from a time the client device is configured into the dummy power-save state for the first set of wireless links;
• and
• removing, by the AP, the client device from the dummy power-save state for one or more of the first set of wireless links over which the AP receives acknowledgments corresponding to the one or more status check messages.
