Abstract: There is provided mechanisms for determining frequency location of a primary cell (PCell) for a wireless device in a carrier aggregation supported communications network having access to a group of low frequency bands and a group of high frequency bands. A method is performed by a network node. The method comprises acquiring an uplink load level for the group of low frequency bands. The method comprises acquiring a pathloss level between a wireless device served by the communications network and the network node. The method comprises selecting, from the acquired uplink load level and pathloss level, which one of the group of low frequency bands and the group of high frequency bands to place the frequency location of the PCell for the wireless device.

Abstract: A transmission apparatus, such as a radio base station, comprising: a power amplifier (3), having an input (3a) and an output (3b), the power amplifier being arranged so as to amplify signals input at its input (3a) and output the amplified signals at its output (3b) for onward transmission, the power amplifier (3) being capable of amplifying input signals to a maximum power; a plurality of signal generating subsystems (2), which are arranged so as to each provide, in use, a signal to be amplified to the input (3a) of the power amplifier (3); and a power control circuit (4), arranged to assign a portion of the maximum power to each subsystem (2) for amplification of each subsystem's signal; in which each subsystem (2) is arranged to provide the power control circuit (4) with a power demand indicative of the power required by that subsystem (2), and in which the power control circuit (4) is arranged to vary the assignment of each subsystem's portion based upon the demands.

Abstract: Each transmitter/receiver pair of a radio base station is connected via an antenna bus and radio frequency feeder to antenna near parts equipment such as active antennas, boosters and tower mounted amplifiers. Automatic configuration and calibration of the antenna near parts equipment is accomplished by establishing communication between the base station and each of its connected antenna near part components. Each antenna near part component sends its identification to the base station over the antenna bus at power-on. Furthermore, communications selectively sent over the radio frequency feeder are monitored to determine the connectivity between individual transmitter/receiver pairs of the base station and each antenna near parts equipment. These radio frequency feeder communications are further processed to determine calibration data for configuring each antenna near parts equipment for optimal operation.

Abstract: Un método, para uso en una estación base de radio, para intercambiar datos entre un nodo de control de equipo de radio (REC) y un nodo de equipo de radio (RE), para transmitir-recibir información por una interfaz de radio empleando múltiples portadoras de antena, estando el nodo de REC separado del nodo de RE y acoplado a él mediante un enlace de transmisión, que comprende los pasos de: generar información de control e información de usuario para transmisión por el enlace de transmisión desde uno de entre el nodo de REC y el nodo de RE, al otro, incluyendo la información de usuario múltiples flujos de datos, cada uno de cuyos flujos corresponde a datos asociados con una antena para una portadora de radio; formatear la información de control y la información de usuario en múltiples tramas multiplexadas por división de tiempo (TDM), cada una de cuyas tramas TDMA incluye un intervalo de tiempo de control para la información de control y múltiples intervalos de tiempo de datos para la información de usuario, y cada uno de cuyos intervalos de tiempo de datos corresponde a un flujo de datos de una de las portadoras de antena; y transmitir tramas por el enlace de transmisión al otro nodo.

Abstract: An interface, apparatus, and method are described for communication between a radio equipment control (REC) node and a radio equipment (RE) node in a radio base station that tranceives information over radio interface using multiple antenna carriers. The REC node is separate from and coupled to the RE node by a transmission link. Both control information and user information are generated for transmission over the transmission link from one of the REC node and the RE node to the other. Many advantageous interface features are described.
