    Abstract: Systems and techniques are disclosed relating to wireless communications. These systems and techniques involve wireless communications wherein a device may be configured to recover an information signal from a carrier using a reference signal, detect a frequency error in the information signal; and periodically tune the reference signal to reduce the frequency error. To prevent GPS performance degradation during LO tuning, a tuning indicator signal may be generated and provided to the GPS receiver to disable GPS operation.

    IPC: H04W64/00

    Abstract: Apparatus and methods are disclosed for determining a position of an access terminal within a wireless communication network. In some examples the access terminal retrieves system information from its current serving cell and stores the retrieved system information in memory along with an associated timestamp. Over time as the access terminal moves about the network it can accumulate this system information for a plurality of base stations within its memory. By utilizing the system information for a plurality of base stations rather than only the current serving base station as well as the associated timestamps additional position information can be provided to the access terminal. Other aspects embodiments and features are also claimed and described.

    Abstract: Un dispositivo de comunicaciones que comprende: un oscilador sintonizable (108) configurado para producir una primera señal de referencia (108b); un receptor (106) configurado para recuperar una señal de información de una portadora utilizando la primera señal de referencia; un procesador (116) configurado para detectar un error de frecuencia en la señal de información y sintonizar periódicamente el oscilador para reducir el error de frecuencia; donde el oscilador sintonizable está configurado adicionalmente para producir una segunda señal de referencia (108a); y el dispositivo de comunicaciones comprende adicionalmente un segundo receptor (102) configurado para recuperar una segunda señal de información de una segunda portadora utilizando la segunda señal de referencia; donde el procesador está configurado adicionalmente para inhabilitar el segundo receptor durante la sintonización del oscilador.
