Abstract
Disclosed is a method for transmitting a signal by a transmission terminal in optical wireless communication. The method may comprise: applying a phase pattern to the wavefront of an optical signal; and transmitting the optical signal. Further, the phase pattern may be determined on the basis of the optical phase conversion characteristics of a phase mask provided in the transmission terminal.
Claims18
A method for transmitting a signal by a transmitting user equipment (UE) in optical wireless communication comprising:
- applying a phase pattern to a wavefront of an optical signal;
- and
- transmitting the optical signal,
- wherein the phase pattern is determined based on optical phase change characteristics of a phase mask provided in the transmitting UE, and
- wherein the phase mask is selected based on feedback regarding a beam divergence measurement of a receiving UE.
A method for receiving a signal by a receiving user equipment (UE) in optical wireless communication comprising:
- receiving, from a transmitting UE, an optical signal having a wavefront to which a phase pattern is applied;
- and
- compensating for the phase pattern applied to the optical signal through an inverse phase mask,
- wherein the phase pattern is a vector composed of values known to the transmitting UE and a receiving UE, and
- wherein the phase mask is selected based on feedback regarding a beam divergence measurement of a receiving UE.
A transmitting user equipment (UE) for transmitting a signal in optical wireless communication comprising:
- a transceiver;
- a phase mask;
- and
- a processor connected to the transceiver and the phase mask,
- wherein the processor is configured to:
- apply a phase pattern to a wavefront of an optical signal through the phase mask;
- transmit the optical signal through the transceiver,
- wherein the phase pattern is determined based on optical phase change characteristics of the phase mask, and
- wherein the phase mask is selected based on feedback regarding a beam divergence measurement of a receiving UE.
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.
