1. An apparatus for wireless communication at an optical wireless communications (OWC) transmitter, comprising:
memory; and
at least one processor coupled to the memory and, based at least in part on information stored in the memory, the at least one processor is configured to:
transmit, to an OWC receiver, a first direct current (DC) bias parameter;
receive, from the OWC receiver, DC bias feedback based on a measurement associated with an OWC link between the OWC transmitter and the OWC receiver; and
transmit an OWC signal with a second DC bias parameter that is based on the DC bias feedback from the OWC receiver.
