Simultaneous Communication with Multiple Transmitters The standard may support interference coordination techniques to deal with simultaneous communication with multiple coordinated/uncoordinated transmitters, which is referred to as multiple-input multiple-output (MIMO). It may support cooperative signal processing among multiple transmitters with negligible impact on latency. The standard may support efficient and reliable feedback and control channels for rate adaptation, multiple user support and cooperative signal processing. This information may be available to other fixed and mobile devices in the network. Waveform The standard will employ at least one PHY mode that uses variable current modulation. Metric Reporting The High Speed Photodiode Receiver may report the following performance metrics to the upper layer via a standardized interface with minimized overhead and low latency: Information about SINR Information about temporal characteristics Signal blocking conditions, frequency of signal losses Signal decay time Low Speed Photodiode Receiver Applications/Use cases The following Low Speed Photodiode Receiver applications/use cases were presented in response to TG7r1 Call for Applications. C1 Underwater/Seaside Communication [8] C2 secure point-to-(multi)point communication [5, 8, 9] C3 Digital signage [5, 8, 17] C4 D2D/IoT [5, 9] C5 LOS Authentication [5, 17] C6 Identification based service [20, 21]
