    Abstract: A base station maximizes a uplink data transmission rate from multiple mobiles treated by the base station as a virtual single uplink transmitter. The base station identifies a set of mobile stations as a candidate transmitting set and determines a transmit power allowable from the mobile stations in the candidate transmitting set. A subset of those mobile stations in the candidate transmitting set is identified. Uplink data transmission rates are assigned and communicated to the subset of mobile stations in the candidate transmitting set so as to optimize a total number of bits processed by the base station associated with the uplink transmissions received from the subset of candidate mobile stations. The optimization may accomplish one or more objectives in addition to optimizing the total number of bits processed.

    Abstract: A mobile terminal includes an access subsystem and an application subsystem. The access subsystem includes at least one access-technology interface. The application subsystem is inter-operably connected to the access subsystem. The application subsystem and the access subsystem are separated via a functional split. The access subsystem provides access by the application subsystem to a first wireless network via a first access-technology interface of the at least one access-technology interface.

    Abstract: A RATIO ACCESS NETWORK (RAN) AND METHOD FOR RAPID HANDOVER OF A MOBILE STATION BETWEEN A SOURCE RADIO NETWORK CONTROLLER (SRNC) AND A TARGET RADIO NETWORK CONTROLLER (TRNC) IN THE RAN. A MOBILE STATION INITIALLY SERVED BY THE SRNC ACCESSES AN ENHANCED GENERAL PACKET RADIO SERVICE (EGPRS) NETWORK THROUGH THE RAN FOR CONDUCTING A PACKET-SWITCHED CALL. WHEN HANDOVER TO THE TRNC IS REQUIRED, THE SRNC NOTIFIES THE TRNC THAT RELOCATION OF THE MOBILE STATION TO THE TRNC IS REQUESTED. THE TRNC RESERVES RADIO RESOURCES REQUIRED TO SERVE THE MOBILE STATION IN THE TRNC, AND NOTIFIES THE SRNC THAT RELOCATION IS APPROVED. AN IUX INTERFACE MAY BE ESTABLISHED BETWEEN THE SRNC AND THE TRNC FOR DIRECT COMMUNICATION OF CONTROL SIGNALING. ALTERNATIVELY, THE CONTROL SIGNALING BETWEEN THE SRNC AND THE TRNC MAY PASS THROUGH THE EGPRS NETWORK. THE EGPRS BEGINS BI-CASTING PACKET DATA UNITS (PDUs) TO BOTH THE SRNC AND THE TRNC UNTIL NOTIFIED BY THE TRNC THAT THE HANDOVER IS COMPLETE. THE MOBILE STATION IS THEN HANDED OVER TO THE TRNC, AND THE EGPRS NETWORK IS NOTIFIED BY THE TRNC THAT TH HANDOVER IS COMPLETE. WITH THE IUX INTERFACE, CONTROL SIGNALING THAT IS SPECIFIC TO THE RAN DOES NOT HAVE TO BE PASSED THROUGH THE EGPRS NETWORK.FIGURE 3

    Abstract: Un método para usar en un dispositivo inalámbrico, para recibir una o más secuencias de sincronización de una señal de sincronización, transmitida en un barrido de haz, comprendiendo el método: - supervisar (S11) un espectro para secuencias de sincronización; y cuando se detecta una primera secuencia de sincronización, entonces: - obtener (S12), mediante el análisis del contenido de la primera secuencia de sincronización detectada, una indicación de temporización que define un tiempo de un evento, en donde la indicación de temporización corresponde a un índice de señal de sincronización por lo que el índice de señal de sincronización permite determinar el momento de un evento en el dispositivo inalámbrico receptor, en el que el momento de un evento comprende el momento de una ventana de acceso aleatorio en la que el dispositivo inalámbrico puede transmitir una señal del enlace ascendente, UL.
