    Abstract: In a communication system (100), a method and apparatus provide for efficient control of call requests from mobile stations (102-104) to base station (101). Mobile station (102-104) receives an initial call request block probability from base station (101), determines an elapsed time from an effective time of the initial call request block probability, and adjusts the initial call request block probability based on an elapsed time. Mobile station (102-104) uses the adjusted initial call request to block call request.

    Abstract: A group of data frames from a plurality of communication channels is received. At least one idle frame including a sequence number of a last frame in the group of data frames is then received. A delay period of time is allowed to elapse after receiving the idle frame before sending a negative acknowledgement message, if at least one data frame is missing.

    Abstract: Techniques for retransmitting data via RLP in a CDMA (e.g., cdma2000) system with a first retransmission mechanism provided by the RLP and a second retransmission mechanism provided by an HARQ-CF. In one method, missing RLP frames are first detected (e.g., by a receiver RLP). A dynamic timer is then maintained (e.g., by a receiver HARQ-CF) for each RLP frame detected to be missing. The dynamic timers are event-driven and have variable time durations. Each dynamic timer is updated based on events known to the receiver HARQ-CF. Fixed timers with fixed time durations may also be maintained (e.g., by the receiver RLP) for the missing RLP frames. Whether or not a missing RLP frame is lost is determined based on the dynamic timer and the fixed timer (if any) maintained for the RLP frame. A NAK may be issued for retransmission of each RLP frame deemed to be lost.

    Abstract: Un procedimiento de comunicaciones inalámbricas en un sistema de múltiples portadoras, comprendiendo: determinar (705, 805) un conjunto de portadoras componente de enlace ascendente a trasmitir concurrentemente por un dispositivo móvil; calcular (710, 810) una potencia de trasmisión máxima asociada con una primera portadora componente en el conjunto, el cálculo teniendo en cuenta incrementos en la potencia de trasmisión de cada portadora componente en al menos un primer sub-conjunto de las portadoras componente de enlace ascendente que incluye una primera portadora componente mediante el incremento proporcional de potencias de trasmisión para cada una del primer conjunto de portadoras componente de enlace ascendente; identificar (715, 815) una capacidad de potencia disponible para la primera portadora componente en base al resultado de calcular la potencia de trasmisión máxima; generar (720, 820) un primer tipo de informe de capacidad de potencia (PHR) comprendiendo la capacidad de potencia disponible para la primera portadora componente; y trasmitir (725) una comunicación PHR incluyendo el primer tipo de PHR.

    Abstract: In a communication system (100), a method and apparatus provides for message integrity regardless of the operating version of an authentication center (198) or an interface (197) between the authentication center (198) and a mobile switching center (199). The method and apparatus include generating a cellular message encryption algorithm (CMEA) key, and generating a CMEA-key-derived integrity key (CIK) based on the CMEA key for message integrity between a mobile station and a base station. The mobile station transmits a registration message to the base station, and determines an operating version of the authentication center (198) in communication with the base station based on whether the mobile station receives a registration accepted order or some elements of an authentication vector from the base station. The CIK is generated based on the CMEA key, if the mobile station receives a valid registration accepted order from the base station.
