Abstract: A method and apparatus for coordinating the time at which a mobile station (5) performs searches for alternative systems to which a hard handoff will occur. In one system which includes the present invention, the mobile station (5) receives a command which instructs the mobile station (5) as to when to tune to alternative frequencies in order to search for indications of the presence of an alternative system. In another system which includes the present invention, predetermined times are defined with respect to a reference point in time that is common to both an origination base station (10) and a mobile station (5). The mobile station (5) tunes to alternative frequencies to perform searches only during these predetermined times. In addition, the mobile station (5) coordinates the transmission of reports which indicate the results of searches for alternative systems such that these reports are only transmitted from the mobile station (5) when the mobile station (5) is tuned to the origination frequency.

Abstract: La invención se refiere a un procedimiento y a un dispositivo mejorados de generación de un canal de gran caudal de datos con amplitud de pico reducida que comprende un conjunto de canales de bajo caudal de datos. El conjunto de canales (90, 92) de bajo caudal de datos experimenta una rotación de fase antes de experimentar un a suma y ser transmitidos. El valor de la rotación de fase depende del número de canales utilizados para formar el canal (102) de gran caudal de datos. Según un modo de realización que utiliza dos canales (90, 92) de bajo caudal de datos, las componentes en fase y en cuadratura de los dos canales se multiplican (94, 96) por un complejo antes de la conversión-elevación mediante sinusoides en fase y en cuadratura. Para un canal de gran caudal de datos constituido además por dos canales de bajo caudal de datos, la componente en fase y en cuadratura de cada canal se convierte y se eleva mediante un conjunto de sinusoides que están desfasadas unas respecto de otras.

Abstract: A method and apparatus are provided for coordinating times at which a mobile station (5) monitors alternative frequencies with times at which an origination base station (10) transmits short messages. The origination base station (10) determines when the mobile station (5) can be tuned to frequencies other than an origination frequency and transmits a signal commanding the mobile station to tune to an alternative frequency at a particular time. The mobile station (5) first receives commands from the origination base station (10). The commands indicate when the mobile station (5) can be tuned to receive frequencies other than an origination frequency. Based on the commands, the mobile station (5) can select time periods during which it will be tuned to frequencies other than the origination frequency. Short messages are transmitted from the origination base station (10) only at times when the mobile station (5) is known to be tuned to receive the origination frequency based on the knowledge of when the mobile station will be tuned to frequencies other than the origination frequency. A window may be created during which the mobile station (5) can cease receiving information over the origination frequency without any reduction in a total amount of data.

Abstract: A method for generating a higher rate channel using a set of N lower rate channels, the method comprises generating a set of N sinusoids having a corresponding set of N phase offsets with predetermined phase rotations; upconverting said set of N lower rate channels using said set of N sinusoids and phase offsets yielding a set of upconverted signals; summing said set of upconverted signals yielding a summed signal whereby the peak-to-average amplitude of said summed signal is reduced based on said phase rotations; and transmitting said summed signal. A corresponding system is also disclosed.
