    Abstract: A base station that is configured for supporting hard handoff as well as the corresponding method is described, the method comprises identify a mobile station (120) potentially performing hard handoff to a base station (110), allocate logical resources of the base station (110) to the mobile station (120) prior to the hard handoff and allocate no physical resources of the base station (110) to the mobile station (120) prior to the hard handoff. Also the mobile station (120) and the corresponding method is described.

    Abstract: Un metodo para variar un nivel de potencia de una seral proporcionada a un amplificador de potencia (232) de un transmisor (200) de un dispositivo de comunicacion inalambrica, que comprende: determinar una frecuencia para transmitir dicha seral desde una antena; determinar una frecuencia minima ymaxima de una banda de frecuencia en la que el dispositivo de comunicacion inalambrica debe operar; determinar una mascara de emision que incluye un primer nivel de potencia maximo al que la antena transmite una seral a la frecuencia minima y un segundo nivel de potencia maximo al que la antenatransmite una seral a la maxima frecuencia; y reducir dicho nivel de potencia de dicha seral proporcionada a dicho amplificador de seral (232) acoplado a la antena en funcion de la proximidad de la frecuencia de la seral a al menos una de las frecuencias minima o maxima.

    Abstract: A plurality of transmission patterns for pilot systems transmitted from a mobile station or base station are provided. Depending upon the frequency selectivity and/or the time selectivity of the channel between the mobile station and the base station, an appropriate pattern is selected. The selected pattern allows for improved receipt of the pilot symbols. In addition, scrambling codes can be applied to the patterns for reducing interference and/or biasing the different mobile stations over the same frequencies and in the same slots.

    Abstract: Methods and apparatus for autonomous handover between WiMAX (Worldwide Interoperability for Microwave Access) and CDMA (Code Division Multiple Access) EVDO (Evolution-Data Optimized) or 1xRTT (one times Radio Transmission Technology, or 1x) networks during normal operation of a dual-mode mobile station (MS) are provided. The methods and apparatus may improve service continuity during handover and need not require any changes to the WiMAX or CDMA standards.
