Abstract: A finger-mounted device may include finger-mounted units. The finger-mounted units may each have a body that serves as a support structure for components such as force sensors, accelerometers, and other sensors and for haptic output devices. The body may have sidewall portions coupled by a portion that rests adjacent to a user's fingernail. The body may be formed from deformable material such as metal or may be formed from adjustable structures such as sliding body portions that are coupled to each other using magnetic attraction, springs, or other structures. The body of each finger-mounted unit may have a U-shaped cross-sectional profile that leaves the finger pad of each finger exposed when the body is coupled to a fingertip of a user's finger. Control circuitry may gather finger press input, lateral finger movement input, and finger tap input using the sensors and may provide haptic output using the haptic output device.

Abstract: Techniques for performing cell detection with interference cancellation are described. In an aspect, a user equipment (UE) may detect for pilots from cells in a wireless network using interference cancellation. The UE may process a received signal to detect for pilots from one or more cells. The pilots may be common pilots transmitted with a reuse factor of one or low reuse pilots transmitted with a reuse factor greater than one. The UE may estimate the interference from a detected cell (e.g., the strongest detected cell) and may cancel the estimated interference from the received signal. The UE may then process the interference-canceled signal to detect for pilots from additional cells. The UE may be able to detect pilots from more cells, e.g., from weaker cells, by canceling the interference due to the pilots from the detected cells. This may be desirable for various applications such as positioning.

Abstract: Techniques for performing cell detection with successive detection and cancellation (SDC) are described. For SDC, pilots from stronger cells may be canceled from a received signal at a user equipment (UE) so that weaker cells may be detected as a result of reduced interference from the stronger cells. In one design, a UE processes a received signal to detect for a cell and determines whether the detected cell is sufficiently strong. If the cell is sufficiently strong, then the UE cancels the interference due to the detected cell from the received signal and further processes an interference-canceled signal to detect for another cell. The UE may detect for cells in a set of cells in a sequential order, from the strongest cell to the weakest cell. The UE may terminate detection when a cell not sufficiently strong is detected or when all cells in the set are detected.

Abstract: Aspects describe a Highly Detectable Pilot that allows a mobile device to detect more base stations and, thus, can provide more accuracy in location estimate. A highly detectable pilot can be transmitted in a portion of one or more data symbols that are not currently being utilized for transmission of data. Transmission of the highly detectable pilot in two data symbols provide a receiver with more convergence time, however, it can take the receiver a longer amount of time to acquire an adequate number of pilots for a location estimate.

Abstract: Methods and apparatus for setting timing of sampling of one or more symbols. The disclosed methods account for at least three types of effective interference (EI) and are used to set the timing of a sampling window for sampling received symbols. The methods includes setting timing based on determining an energy density function accounting for both static and dynamic EI, determining the minimum of a total energy profile and sliding the sampling window to ensure that the minimum point is at a predetermined point, and determining and using a composite energy profile accounting for short term and long term fading effects. The disclosed apparatus include a transceiver employing one or more of the disclosed methods for setting timing when receiving the symbols.

Abstract: Systems and methodologies are described that facilitate transmitting pilot signals over resources selected based on a dynamic variable common to a wireless network. The resources can also be selected based on an identifier of a related access point to provide multiple levels of diversity in transmitting the pilot signal. Thus, a resource selected for a given access point can vary over subsequent frames and additionally vary with respect to other access points. A hash function can be utilized with the access point identifier to divide resources among access points, and using the dynamic variable, such as a frame identifier, can modify the selected resources over subsequent frames. This allows mobile devices to receive the pilot signals from access points at varying locations, for location determination in one example, with decreased interference.

Abstract: A method (1700) and apparatus (1801) provide channel estimation with extended bandwidth filters. Antenna (1813) receives a signal such as a pilot signal and detects a bandwidth associated with the pilot signal in a detector (320). One of a plurality of filters (603, 605, 607, and 609) including extended bandwidth filters (311) and a default filter (305) can be selected by a selector (617). If the detector detects activity associated with a wider bandwidth, the filter associated with the wider bandwidth is selected over the presently selected filter. If no activity is detected, the default filter is selected.

Abstract: Quality-of-service for different communication services that share a common physical link (such as at least one code division multiplexing code) is provided. Outer power loop control serves to maintain quality-of-service for a selected one of the communication services that has, in a preferred embodiment, a highest relative requirement for quality-of-service. Rate matching parameters are then selected independent of transmission energy factors to ensure that the remaining communication services abide by their corresponding quality-of-service requirements.

Abstract: In a wireless communication system, a scheduler (100) determines (306) a first set of modulation and coding schemes (MCSs), each of which produces a maximum data rate for a first user, in accordance with available resource constraints (304) of the wireless communication system. The scheduler then forms, for each MCS of the first set, a second set of MCSs that produces the maximum data rate for a second user in accordance with a first residual resource (314) that remains when applying that MCS to the first user, thereby producing (316) a group of second sets of MCSs. After producing the group of second sets, the scheduler selects (324), from the first set and for the first user, a first optimal MCS corresponding to one of the group of second sets that allows a highest maximum data rate for the second user.
