Abstract: Un radioteléfono (104) de un sistema de radioteléfonos (100) ingresa en un modo de inactividad de baja potencia y regula la duracion del modo de reposo usando un generador de reloj de inactividad (205) de resolucion gruesa. El radioteléfono sincroniza el ajuste horario del radioteléfono al ajuste del sistema, por medio de un oscilador (116) de resolucion fina. Luego, el radioteléfono sale del modo de inactividad de baja potencia, sincronizado con el ajuste del sistema.

Abstract: A wireless communication device 100 acquires a pilot channel before an assigned slot when the wireless communication device is operating in the slotted mode of a CDMA system. The wireless communication device comprises a searcher receiver 107 that determines the short-term average pilot strength of active and neighbor pilot channels. Finger receivers 107 determine the long-term average pilot strength of the active and neighbor pilot channels. A logic and control circuit 113 assigns the finger receivers to the pilot channels according to their short-term average pilot strength, determines if the long-term average pilot strength of a neighbor channel is greater than the active pilot channel's pilot strength, and determines to hand off to the neighbor pilot channel with the greater long-term average pilot strength. Moreover, an early detection correlation length can be dynamically adjusted according to the pilot strength of the active pilot channel to shorten the pilot acquisition process.

Abstract: A radiotelephone (104) in a radiotelephone system (100) enters a low power sleep mode and times the duration of the sleep mode using a sleep clock generator (205) having a coarse resolution. The radiotelephone synchronizes timing of the radiotelephone to system timing using an oscillator (116) having a fine resolution. The radiotelephone then exits the low power sleep mode synchronized with system timing.

Abstract: A searcher receiver 114 includes a sample buffer 202 which stores signal samples loaded using a real time clock. A real time linear sequence generator (RT LSG) 206 stores an initial state and is clocked using the real time clock. The contents of the RT LSG are loaded into a non-real time linear sequence generator (NRT LSG) 208 when sample processing begins. Samples are correlated using a non-real time clock to allow signal processing to be uncoupled from the chip rate. The analog front end may be powered down or tuned to another frequency during non-real time processing.

Abstract: An apparatus (100) maintains a Pilot Set in a digital communication system that utilizes Code Division Multiple Access. The apparatus comprises a logic and control circuit (113) for providing instructions to a searcher receiver (109) which sequentially scans active pilots, then candidate pilots, and then pre-candidate pilots. The scan of the pre-candidate pilots continues until all but a predetermined number of pre-candidate pilots have been promoted or demoted. Then the searcher receiver alternately scans the predetermined number of pre-candidate pilots and neighbor pilots. Alternate scanning is terminated when a one of the neighbor pilots is promoted, and scanning of the pre-candidate pilots is resumed. The invention is described as especially suited for use in a cellular or Personal wireless communication system in which mobiles promote and demote pilot frequencies between neighbor and candidate sets (via a pre-candidate set) in accordance with measured pilot signal strength, and a base station promotes and demotes pilot frequencies between candidate and active sets during hand-off.

The wireless communication device comprises a searcher receiver 109 that determines the short-term average pilot strength of active and neighbor pilot channels. Finger receivers 107 determine the long-term average pilot strength of the active and neighbor pilot channels. A logic and control circuit 113 assigns the finger receivers to the pilot channels according to their short-term average pilot strength, determines if the long-term average pilot strength of a neighbor channel is greater than the active pilot channel's pilot strength, and determines to hand off to the neighbor pilot channel with the greater long-term average pilot strength. Moreover, an early detection correlation length can be dynamically adjusted according to the pilot strength of the active pilot channel to shorten the pilot acquisition process.
