Abstract: Methods and apparatus are presented to optimize the likelihood of a successful acquisition of frame timing information of an asynchronous base station by providing a mechanism that copes with short-term degradations caused by a dynamic radio environment. An acquisition search is performed in a plurality of stages, wherein a declaration indicating a failure at a stage is delayed through the use of a verification stage. The verification stage can be repeated a variable number of times. The number of repetitions of the verification stage can be dependent upon the stage at which the failure occurred. Declaration of failure occurs only after the predetermined number of verification searches have been performed.

Abstract: Techniques to efficiently process paging channels in an asynchronous wireles s communication system (100). In one aspect, if the base stations (104a, b, c) are not synchronized with each other and a remote terminal's (106) designate d page time is different from base station to base station, the remote termina l (106) can wake up based on the earliest base station in a reacquisition sear ch list (712) that includes candidate base stations to which the remote termina l may be handed off. In another aspect, the criteria to select base stations f or evaluation as reacquisition targets may be based on the received power (512) of the base stations as well as their timing (514), both of which may be mad e relative to that of a preferred base station. In yet another aspect, the remote terminal may wake up multiple times in a particular paging cycle (i.e ., a frame cycle or a DRX cycle) if there are one or more candidates base stati on to which the remote terminal may be handed off.

Abstract: Un procedimiento para aumentar la probabilidad de una adquisición satisfactoria de la temporización de una estación (14) base mediante una estación (12) móvil, que comprende: realizar una búsqueda de adquisición de tiempo de trama tras una transmisión desde la estación (14) base, en el que la búsqueda de adquisición del tiempo de trama comprende una pluralidad de etapas y la transmisión comprende una pluralidad de tramas de radio; y realizar al menos una búsqueda de verificación después de al menos una de la pluralidad de etapas, si se determina un fallo en la al menos una de la pluralidad de etapas, en el que el número de búsquedas de verificación realizadas después del la al menos una de la pluralidad de etapas depende de la etapa en la que se produce el fallo, en el que la búsqueda de verificación es una búsqueda para identificar una pluralidad de picos de ranura.

Abstract: Techniques for reducing the time required for frequency scan in acquisition are disclosed. In one aspect, received power measurements are made at one or more of the possible carrier frequencies and system search is performed on o ne or more of those frequencies when the power measurement exceeds a threshold. In another aspect, the power is measured at one or more frequencies in a ban d of frequencies surrounding a frequency at which the measured power exceeded a threshold. If the measured power at one or more of the frequencies in the ba nd exceeds a second threshold, a system search is performed at one or more of those frequencies. In yet another aspect, frequencies meeting certain criter ia are sorted in order of measured power prior to system search or further powe r measurement, and subsequent processing is performed in order of descending measured power. Various other aspects are also presented. These aspects have the benefit of reducing acquisition time, which results in faster system access and allows for more efficient use of system resources.
