    Abstract: Un procedimiento de comunicación, que comprende: obtener (208) contexto de portador en un terminal de acceso; desactivar (216) el contexto de portador en el terminal de acceso, en el que la desactivación se desencadena si el terminal de acceso no puede comunicarse con la entidad de red; recuperar (218) la conectividad a la entidad de red; y sincronizar (220) el contexto de portador con una entidad de red después de la desactivación.

    Abstract: EXISTING CRITERIA FOR ANALYZING RADIO LINK FAILURE CONDITIONS MAY NOT SATISFACTORILY ADDRESS THE CONDITIONS BETWEEN CELLS THAT SUPPORT COOPERATIVE RESOURCE COORDINATION. GENERALLY, WHEN THE UE DECLARES RADIO LINK FAILURE, THE UE DISCONTINUES COMMUNICATION WITH A SERVING BASE STATION (110A) AND SEARCHES FOR A NEW BASE STATION. WHEN THE UE LIES IN A REGION WITH SEVERE INTERFERENCE, WHERE THE INTERFERENCE IS COORDINATED BETWEEN BASE STATIONS (110A,110B,110C) BY THE INTERFERING CELL YIELDING PART OF ITS RESOURCES, THE UE MEASUREMENTS FOR DETERMINING RADIO LINK FAILURE (RLF) MAY VARY CONSIDERABLY, DEPENDING ON WHETHER THE MEASURED RESOURCES WERE YIELDED BY THE INTERFERING CELL. WHEN THE UE MEASURES RESOURCES WHICH WERE NOT YIELDED BY THE INTERFERING CELL, THE UE CAN ERRONEOUSLY DECLARE RLF (E.G., DUE TO HIGH INTERFERENCE), ALTHOUGH THE UE CAN STILL ACCESS THE SERVING CELL USING RESOURCES YIELDED BY THE INTERFERING CELL. ACCORDINGLY, DISCLOSED ARE ASPECTS FOR DETERMINING RLF BASED BY ACCOUNTING FOR COOPERATIVE RESOURCE COORDINATION EMPLOYING YIELDED RESOURCES. (FIGURE 6)

    Abstract: Un procedimiento de selección de servicio de comunicación inalámbrica realizado por un terminal de acceso, que comprende: seleccionar una primera tecnología de acceso por radio, RAT, que incluya un dominio de conmutación de circuitos, CS, para el acceso a un servicio; caracterizado por: pedir (3-3) el registro a la primera RAT que incluye el dominio CS a través de una segunda RAT que incluye un dominio PS de conmutación de paquetes; tras recibir (3-5) un rechazo al registro a la primera RAT que incluye el dominio CS, liberar de forma autónoma (3-6) una conexión a la segunda RAT que incluye el dominio PS; y pedir (3-7) el registro a la primera RAT a través de la primera RAT, en donde el solicitante incluye comunicar un mensaje que oculta que el terminal de acceso es capaz de comunicarse con la segunda RAT.

    Abstract: Systems and methods providing uplink coordinated multi point (CoMP) communication are shown. A second cell may identify at least one first UE communicating with a first cell and capable of causing high uplink interference to the second cell. The second cell may estimate uplink interference from the at least one first UE at the second cell. The second cell may estimate uplink interference on specific resources. For example the second cell may determine resources assigned to the at least one first UE for data transmission to the first cell (e.g. using pre scheduling information provided by the first cell) and estimate uplink interference from the at least one first UE on the resources assigned to the at least one first UE. The second cell may schedule at least one second UE for uplink data transmission to the second cell based on the estimated uplink interference from the at least one first UE.
