1. A user equipment device (UE), comprising:
one or more radios operably coupled to respective antennas; and
a processor operably coupled to the one or more radios;
wherein the UE is configured to:
establish a connection with an access point through a wireless local area network (WLAN), wherein the connection utilizes a plurality of links;
transmit an indication to the access point through a first link of the plurality of links, wherein the indication comprises a bit field, wherein a first bit of the bit field indicates that the first link is available for the UE to receive downlink (DL) communications from the access point, wherein the bit field comprises a power management (PM) field, wherein the first bit indicates the first link is available for the UE to receive DL communications when the first bit is set to 0, and wherein the first bit indicates the UE is in a power save mode and the first link is currently unavailable for the UE to receive DL communications when the first bit is set to 1; and
receive one or more DL communications from the access point through the first link.
