    Abstract: Methods, systems, and devices are described for transmitting an identifier using visible light communication (VLC) and for generating a plurality of identifiers for transmission using VLC. Input identifying an illumination factor associated with a light source is received. A first set of modulation parameters is modified for transmitting the identifier using VLC. The first set of modulation parameters is modified based on the illumination factor. A signal, in which the identifier is encoded, is applied to the light source. The signal is applied according to the first set of modulation parameters. Another method includes identifying a number of light transmitting devices, generating a plurality of identifiers based on the identified number of light transmitting devices, storing the generated identifiers, determining a plurality of cyclic shifts for each identifier in the plurality of identifiers, and removing identifiers from the plurality of identifiers that match the identified cyclic shifts.

    Abstract: A hybrid communications system implements different communication technologies to communicate data and information for particular communications directions in different portions of the system. Power line communications (PLC) signaling is used to deliver data and information from a gateway device to a light access point. Visible light communications (VLC) signaling is used to communicate data and information from the light access point to a user equipment (UE) device. Wireless radio signaling, wireless infrared (IR) signaling, or a combination of wireless IR signaling and PLC signaling is used to communicate data/information from the UE device to the gateway device. To efficiently control the VLC communications channel between the light access point and UE device, the UE device measures the VLC channel, e.g., calculating SNRs on a per VLC tone basis, and communicating VLC channel quality feedback information to the gateway device, which is forwarded to the light access point.

    Abstract: Various embodiments relate to using available spectrum for peer to peer communications and for selecting which of several possibly available channels should be used. Various methods and apparatus are well suited to peer to peer networks in which channel usage decisions are made in a decentralized manner. A wireless terminal generates a list of potential available channels to be used for peer to peer communications, e.g., based on FCC information and/or local sensing. Channels are filled in accordance with a predetermined channel ordering. A wireless terminal migrates between the channels in accordance with changes in the number of peer devices using a channel. The network, in a distributed manner, changes the number of channels in use at a location in response to changes in numbers of active peer devices at a location.

    Abstract: A user equipment (UE) device includes a VLC receiver including a photodiode and a radio receiver. The UE device supports a plurality of alternative technologies, communications protocols, and/or frequencies. During a first mode of operation, e.g., a discovery mode, a low reverse bias voltage value is applied to the photodiode. The low reverse bias voltage is adequate to support the recovery of small amounts of communicated information, and the power consumed by the battery of the UE device is relatively low. During discovery, information communicated includes, e.g., a light transmitter ID, an access point ID, services available at the access point, configuration information for a light receiver and/or for an auxiliary radio receiver. During a second mode of operation, e.g., a data traffic mode, the reverse bias voltage applied to the photodiode is set to a high reverse bias voltage to support higher data rate using VLC.
