Techniques for visible light communication-assisted broadcast transmissions

An apparatus for wireless communications at a base station, comprising:

• at least one processor;
• at least one memory coupled with the at least one processor, with instructions stored in the at least one memory, the instructions being executable by the at least one processor, individually or in any combination, to cause the apparatus to:
• transmit, to a user equipment (UE), an indication that the base station supports visible light communications;
• transmit, to the UE, system information or radio resource control signaling that indicates visible light communication assistance information for broadcast visible light communication messages;
• transmit, in accordance with the indication and via one or more light emitting diodes, a visible light communication message comprising a content that triggers activation of a radio frequency receiver at the UE;
• and
• communicate via radio frequency communications with the UE based at least in part on transmitting the visible light communication message.

A method for wireless communications at a user equipment (UE), comprising:

• receiving, from a base station, an indication that the base station supports visible light communications;
• receiving, from the base station, system information or radio resource control signaling that indicates visible light communication assistance information for broadcast visible light communication messages;
• deactivating a radio frequency receiver of the UE based at least in part on receiving the indication;
• receiving a visible light communication message at a photo detector of the UE;
• activating the radio frequency receiver of the UE based at least in part on a content of the visible light communication message;
• and
• communicating with the base station using the radio frequency receiver.
