Abstract: Some wireless communications systems may utilize optical wireless communication (OWC) to transmit or receive information. For instance, a first device may communicate with a second device via an OWC link. Some OWC systems may operate in an optical spectrum between approximately 1011 and 1016 hertz. Some examples of the techniques described herein may provide communication performance improvements by utilizing frequency-dependent communication structures for OWC. For example, frequency-dependent constellation patterns may be utilized for a codeword. Utilizing frequency-dependent constellation patterns may contrast with some approaches that utilize one modulation and coding scheme (MCS) per codeword. In some aspects, allocated frequency domain resources may be arranged into subbands with different MCSs. In some examples, an optical channel with relatively little or no fading may allow streamlining of channel state or control signaling. For example, MCS patterns may be updated relatively less frequently.
