Abstract: Un procedimiento de transmisión de información de control entre una unidad (18) móvil y una estación (12) base en sistema de comunicaciones de espectro ensanchado: vigilar mediante una unidad (18) móvil el nivel de potencia de señales de control recibidas desde múltiples estaciones (12, 14, 16) base; identificar mediante la unidad móvil un primer conjunto de estaciones base para las que el nivel de potencia recibido de la señal de control recibida excede un nivel prescrito; enviar un mensaje de medición de potencia desde la unidad (18) móvil a al menos una estación (12) base en el conjunto que identifica las estaciones base en el primer conjunto identificado; enviar a la unidad (18) móvil mediante al menos una estación base un mensaje que especifica un segundo conjunto de estaciones base a las que se permite transmitir a la unidad (18) móvil en traspaso continuo; y comunicar un mensaje de control a la unidad (18) móvil en traspaso continuo desde múltiples estaciones base que son elementos tanto del primer conjunto como del segundo conjunto; caracterizado porque al menos un elemento del segundo conjunto de estaciones base se determina basándose no sólo en la información proporcionada mediante la unidad (14) móvil en dicho mensaje de medición de potencia, sino también en información de permiso en una tabla de traspaso en un controlador de estación base que comprende indicadores de permiso de traspaso que identifican otras estaciones base en la lista de vecinos de la estación pase para la que se permite un cierto tipo de traspaso.

Abstract: The present invention relates to wireless voice and data communication systems. More particularly, the present invention relates to novel and improved methods and apparatus for transmitting data traffic on a communication channel. One such method comprises the steps of packaging a data payload into a plurality of subpackets; transmitting a first subpacket to a remote station; if the channel conditions are optimal, transmitting a remaining portion of the plurality of subpackets to the remote station; and if the channel conditions are not optimal within a predetermined time duration, then transmitting a remaining portion of the plurality of subpackets during unfavorable channel conditions. The apparatus may comprise means for packaging a data payload into a plurality of subpackets; means for transmitting a plurality of subpackets to a remote station; means for deciding, after the means for transmitting a plurality of subpackets has transmitted a first subpacket, whether: if the channel conditions are optimal, to transmit a remaining portion of the plurality of subpackets to the remote station; and if the channel conditions are not optimal within a predetermined time duration, then to transmit a remaining portion of the plurality of subpackets during unfavorable channel conditions.

Abstract: A method and apparatus for quickly acquiring synchronization of a signal in WCDMA communication system utilizing variable duration sample accumulation, validity testing of decoder estimates, and parallel decoding of multiple synchronization signals within a PERCH channel. The receiver (204) accumulates the samples necessary to reliably determine slot tuning. Until slot timing estimates pass a validity test, samples are accumulated (304A, 304B) for frame timing estimates. Until frame timing estimates pass a validity test, samples are analyzed to determine the pilot offset of the channel.

Abstract: Systems and techniques for communications wherein a data packet is transmitted over at least one time slot from a transmission site, a value is computed from an initial value and information, the initial value being is function of the number of time slots of the data packet transmission, the value and the information is transmitted from the transmission side, the transmitted value and the intonnaliun is received a receiving sue, the value from the received information is recalculated, and the number of time slots of the data packet transmission is determined from the calculated and recalculated value. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject manner of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or the meaning of the claims.

Abstract: The structure of a time-multiplexed physical channel is used to time inter-frequency or inter-system search excursions. A mobile station that receives an instruction to perform a search excursion prepares for the search excursion by detecting the first radio frame of a message frame. Transport format combination indicator bits are extracted from the first radio frame and stored. After the search excursion is performed, the mobile station recalls the stored indicator bits and uses the indicator bits to decode other radio frames of the message frame.
