    Abstract: Disclosed are methods, systems, devices, apparatus, computer-/processor-readable media, and other implementations, including a method, at a processor-based mobile device, that includes determining a first set of candidate positions of the mobile device corresponding to a first time instance based, at least in part, on position data including a first set of identifiers decoded from signals including respective first one or more light-based communications received by the mobile device from a first one or more light devices, with the mobile device being located at a first location at the first time instance. The method further includes selecting at least one candidate position from the first set of candidate positions, in response to a determination that the first set of candidate positions includes more than one candidate position, in order to resolve positional ambiguity, based, at least partly, on further position data from further signals from one or more devices.

    Abstract: One or more bits are used in peer discovery signals to signal a device's ability and/or willingness to participate in a cooperative manner with regard to one or more mobile device location determination related operations. In some embodiments, the one or more bits are located at predetermined locations within a header portion of a peer discovery signal. Different bits, in some embodiments, are associated with different specific cooperative location determination related operations. The peer discovery signal is transmitted, e.g., broadcast, periodically or on some predetermined basis by a mobile wireless communications device. In this manner, a device listening to the peer discovery signals can determine other devices' willingness to perform particular location discovery related operations with very little signaling overhead.

    Abstract: Methods and apparatus for controlling access to secure areas are described. Time varying values are generated from access device identifiers, e.g., door identifiers. The time varying value, e.g., a hashed door identifier value, is transmitted as a VLC signal by a luminaire near the door to which the hashed identifier corresponds. A mobile detects the transmitted hashed door identifier value and sends an access request via a wireless signal, e.g., a radio signal. The access request includes a value generated from the received hashed door identifier and a mobile device identifier. A control device determines, from information in the access request and stored information indicating which mobile devices have authority to access which doors, if access should be granted to the door corresponding to the hashed access device identifier from which the received information was generated. The received information may be hash of the mobile identifier and hashed door identifier.

    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.

    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: Mobile devices are used as temporary location anchor points, e.g., to supplement fixed location permanent location anchor points, in a wireless communications system in which mobile device locations are determined. A mobile device receives a command or request to operate as a location anchor point. In some embodiments, the command includes time information indicating the amount of time the mobile device is to operate as a location anchor point. In some embodiments, a mobile device operating as a location anchor point reports a received signal strength measurement along with information identifying the device from which the signal was received to a network element, e.g., a location server node. In some embodiments, a mobile device operating as a location anchor point broadcasts a signal providing location information. The mobile device receives compensation for operating as a location anchor point. Compensation may be monetary, services, or benefits provided by the network.
