Classification: CPC H | IPC H

Claim 14:
15. A receiving user equipment (UE) for receiving a signal in optical wireless communication comprising:
a transceiver;
an inverse phase mask; and
a processor connected to the transceiver and the inverse phase mask,
wherein the processor is configured to:
receive, from a transmitting UE, an optical signal having a wavefront to which a phase pattern is applied, through the transceiver; and
compensate for the phase pattern to which the optical signal is applied, through the inverse phase mask,
wherein the phase pattern is composed of values known to the transmitting UE and the receiving UE, and
wherein the phase mask is selected based on feedback regarding a beam divergence measurement of a receiving UE.
