摘要： Various embodiments are directed to methods and apparatus for mobile device position determination and the efficient communication of mobile device position related information. In different areas different types of reference signals may be available to be used by a mobile device for position determination. Some types of references signal may be well suited for an indoor environment, e.g., audio signals, Bluetooth signals and Wi-Fi signals, while other types of signals may be well suited for an outdoor environment, e.g., GPS signals and cellular base station signals. Different types of signals may facilitate different possible resolution accuracies for a position determination. In various embodiments, in different areas within a geographic coverage region, different sets of reference signals are available to determine its position. In some embodiments, different position determination resolutions are used in different area as a function of the reference signal type which is available.

摘要： A set of signal prediction map generation parameters, used to generate a signal prediction map to determine mobile device location, are initially modeled as large variance random variables. A network device, e.g., a server, receives estimated positions of mobiles and corresponding signal measurements, e.g., received signal power measurements, taken at those estimated positions by the mobiles. Received signal measurement information and corresponding estimated position information from a mobile is used to update one or more of the signal prediction map generation parameter distributions. After multiple updates to a distribution of a signal prediction map generation parameter, the network node transmits a prediction parameter update signal communicating the new distribution of the signal prediction parameter to be subsequently used by the mobile devices in the system when generating a signal prediction map and estimating its position.

摘要： Various methods and apparatus are directed to communicating peer discovery information in an efficient manner. A wireless device which has received peer discovery information from multiple peer devices in its vicinity combines received peer discovery information and transmits a signal communicating the combined information. In some embodiments, the combining includes performing a linear combination. The transmitted signal including the combined peer discovery information corresponding to multiple devices facilitates the recovery of peer discovery information by peer devices which may be out of direct peer to peer communications range to one of the devices whose information was used to produce the combined signal. Different peer devices may be able to recover different peer discovery information from the same combined signal. Thus the wireless device may effectively relay a first peer discovery message to one peer device and a second peer discovery message to another peer device via the same combined signal.

摘要： A wireless communications device, e.g., a mobile node supporting direct peer to peer communications, performs a self-calibration of one or more of: receiver IQ imbalance, transmitter IQ imbalance, receiver DC offset, and transmitter DC offset. The wireless communications device, operating in calibration mode, intentionally sets the oscillator frequency used for downconversion in its receiver module to a different frequency than the oscillator frequency used for upconversion in its transmitter module. A first baseband signal, e.g., a single tone test signal, is input to the transmitter module and an upconverted transmit signal is generated. The transmit signal is routed via a feedback loop to the receiver, which performs a downconversion operation. Power and/or phase measurements of the signals output from the downcoversion are used to determine IQ imbalance compensation information and DC offset compensation information. The determined compensation information is used subsequently when operating in a communications mode of operation.
