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: Procedimiento para generar un canal de tasa de transferencia elevado utilizando un conjunto de N canales de tasa de transferencia inferior, comprendiendo el procedimiento: generar un conjunto de N sinusoides que tienen un conjunto correspondiente de N desfases con rotaciones de fase predeterminadas; convertir por elevación dicho conjunto de N canales de caudal inferior utilizando dicho conjunto de N sinusoides y los N desfases, produciendo un conjunto de señales convertidas por elevación; sumar dicho conjunto de señales convertidas por elevación, produciendo una señal sumada mediante lo cual la amplitud de pico a media de dicha señal sumada se reduce sobre la base de dichas rotaciones de fase; transmitir dicha señal sumada; y en el cual, antes de dicha generación de un conjunto de N sinusoides, el procedimiento comprende: generar una componente en fase y una componente en cuadratura de fase a partir de cada uno de dichos N canales de tasa de transferencia inferior; y a continuación, sumar la componente en fase de uno de dichos N canales de tasa de transferencia inferior con la componente en cuadratura de fase de otro de dichos N canales de tasa de transferencia inferior, en el cual dicha generación de un conjunto de N sinusoides comprende, además, la rotación de los N desfases de 90º respecto de dicho conjunto de N desfases.

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.

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.
