Abstract: Light sources are affixed at appropriate positions in a multilevel structure or in an obstructed environment. The light sources generate modulated light signals, such as controlled light-emitting diodes, which identify the positions of the light sources by their three-dimensional global positioning coordinates and/or equivalent representation that specifies their in situ locations in the environment. Mobile communication devices, upon receiving the light signals, can derive spatial positioning information and transmit such information to a remote location, such as an emergency response system.

Abstract: A transceiver circuit and a method in a wireless communication network are provided, where a signal power level for a signal received at the transceiver circuit is measured and compared to a predefined threshold power level. At least two groups of power amplifiers may be used, where one group is optimized for high efficiency above the predefined threshold power level, and one group is optimized for high efficiency below the predefined threshold power level. The amplifiers may be used to amplify the received signal depending on the signal power level in relation to the predefined power threshold level. The signal may then be filtered by duplex filters and forwarded to a diversity antenna or a main antenna where it is transmitted over an air interface.

Abstract: A portable device authorizes a payment transaction from an account associated with the portable device. The portable device comprises a communication system, such as a near field communication (NFC) system, for communicating with a transaction system of a merchant or other receiving entity, a user interface, a memory storing account information for each of a plurality of accounts, and a transaction application. The transaction application applies at least one predetermined selection rule to the plurality of accounts to determine a selected subset of the plurality of accounts. A display of the user interface displays, under control of the transaction application, a plurality of transaction option indicators. Each transaction option indicator, which may be text or graphic, represents a one of the accounts within the selected subset of accounts. The transaction application prompts user selection of a selected one of the transaction option indicators.

Abstract: An electronic device such as a cellular telephone, for example, includes a receiver that receives broadcast radio signals transmitted by a commercial broadcast radio station. The broadcast radio signals include information that identifies a location of the radio station, an antenna associated with the radio station, or the radio station. The device also includes positioning circuitry to allow the device to determine its current location. A controller in the device extracts the information identifying the radio station from the received broadcast signal, and acquires one or more satellites of a navigational system based on the information.

Abstract: A femtocell base station is configured to transmit site-specific services data to in-range wireless devices, using a common broadcast channel. The site-specific services data identifies available services including, but not limited to, alternate radio signals available in the vicinity, such as FM radio signals, wireless local-area network (WLAN) signals, and the like; location-related services, including the availability of location beacon signals and/or location assistance data for use in position determination using assisted-GPS technology; and physical resources available to the device user, such as printers, copy machines, vending services, and the like. An exemplary mobile station is configured to extract site-specific services data from the femtocell base station signal, and to access a second radio signal using the site-specific services data.

Abstract: Disclosed is a system and method for channel decoding speech frames in a receiver capable of multiple (M) codec modes, wherein channel encoded speech frames include an inband bit portion and a speech portion. An inband bit decoder decodes the inband bit portion (700) of a received frame to obtain confidence levels associated with each of the M codec modes. Using these confidence levels, the codec modes are ordered from most to least likely. The speech frame is then decoded by a channel decoder using the most likely codec mode (704). A frame determination check (720) is performed to determine the quality of the decoded speech frame. If the decoded speech frame is determined to be of poor quality, then the channel decoding process is repeated using the next most likely codec mode (736) corresponding to the next highest inband bit decoding confidence level. This process is repeated until a good speech frame is decoded or some exit criteria is reached.

Abstract: To perform closed loop power control, a receiving station measures the signal strength of a received signal transmitted from a transmitting station, generates periodic power control commands based on the signal strength measurements, and transmits the periodic power control commands to a transmitting station to control the transmit power level of the transmitting station. A power control filter is used to adapt the power control mechanism when the transmitting station is operating in a compressed mode to compensate for intermittent transmission by the transmitting station in the compressed mode.

Abstract: A base station monitors the uplink load and sends control signals to one or more mobile terminals to selectively enable and disable compressed mode operation. The base station can divide the mobile terminals into groups and can assign different compressed mode patterns to different groups of mobile terminals so that the transmissions from mobile terminals in different groups while in compressed mode are not synchronized. If load imbalances occur, the network can reassign mobile terminals from one group to another.

Abstract: A method of estimating initial channel quality in a receiver when allocated a new channel in order to select an optimal codec mode in a multi-rate service is disclosed. One implementation initially fills the filter state with the first received channel quality measurement. Another embodiment proportionally fills the entire filter state with the calculated channel quality measurements. Yet another embodiment uses the hysteresis and threshold parameters in conjunction with the initial codec mode to calculate an initial fill value for the filter state.
