摘要： An apparatus and method are provided for performing a handover analysis. The apparatus comprises base station location identifying circuitry to obtain base station location information for a plurality of base stations that provide a wireless network for communication with a moving vehicle. In addition, moving vehicle tracking circuitry is provided to obtain position and velocity information for the moving vehicle. Handover metrics computation circuitry is then used to generate at least one handover metric computed from the position and velocity information for the moving vehicle and the base station location information, for use in determining a target base station in said plurality to be used when performing a handover procedure to transition communication with the moving vehicle from the current base station in said plurality to the target base station. By such an approach, this enables a variety of handover metrics to be generated that take into account the deployment of the wireless network, which can be useful in systems such as Air to Ground (ATG) systems where the moving vehicles have a relatively high velocity, and the base stations may be relatively far apart. Such an approach can enhance the algorithms used to evaluate the decision to trigger handover from one base station to another base station.

摘要： A wireless communication system for a moving vehicle, and a method of operation of a wireless communication system for a moving vehicle, are described. The wireless communication system comprises an antenna system configured to receive a received signal from a further antenna system and to transmit a transmitted signal to the further antenna system, communication control circuitry to control operation of the antenna system, and analysis circuitry. The analysis circuitry is configured to obtain at least one item of information from the received signal, and perform a Doppler adjustment process to determine, based on the at least one item of information, an adjusted transmitted frequency (ft) to be used for transmission of the transmitted signal from the antenna system, such that an observed frequency of the transmitted signal at the further antenna system is a predetermined uplink frequency (fUL).

摘要： A technique is provided for controlling a beam pattern employed by an antenna apparatus. The antenna apparatus comprises an antenna array, and beamforming circuitry to employ a beam pattern in order to generate a beam using the antenna array to facilitate wireless communication with at least one further antenna apparatus. Beam pattern adjustment circuitry is then arranged to receive a control signal indicative of a motion being imparted to the antenna apparatus, and to adjust the beam pattern to be used by the beamforming circuitry in dependence on the control signal, so as to alter a width of the beam in order to mitigate variation in link quality of the wireless communication due to the motion. This hence allows the width of the beam deployed by the antenna apparatus to be adjusted taking into account motion being imparted to the antenna apparatus, so that a balance can be achieved between employing a narrow beam to seek to improve range and resilience to interference, and a wider beam to reduce the variation in link quality that might otherwise arise due to the motion.

摘要： A communication apparatus, terminal apparatus, system and method are provided for performing wireless communication. The communication apparatus supports a plurality of component carriers, wherein one of the plurality of component carriers is designated as a current primary component and at least one of the plurality of component carriers is designated as a current secondary component carrier providing at least downlink communication. The communication apparatus comprises control circuitry for controlling a component carrier testing procedure for one or more component carriers. The testing procedure comprises, for each component carrier: establishing an uplink connection from the terminal apparatus to the communication apparatus using the component carrier; and determining a quality of the uplink connection for the component carrier. The control circuitry is responsive to completion of the testing procedure to designate an updated primary component carrier on the basis of the qualities of the uplink connections determined for the component carriers.

摘要： Methods and apparatuses for configuring the zone served by a base station providing wireless communication for a plurality of user equipment located in moving vehicles are disclosed. Motion reports are received from the user equipment, indicating a current location, a current direction of motion, and a current speed of the moving vehicles. The motion reports are received from at least one of: user equipment currently using the base station for wireless communication; user equipment currently within the zone served by the base station, but not using the base station for wireless communication; and/or user equipment currently using at least one neighbouring base station to the base station for wireless communication. A configuration for the zone served by the base station is then determined, based on the motion reports and on locations of the base station and of the at least one neighbouring base station. The configuration for the zone served by the base station is then applied to the base station.

摘要： An antenna apparatus is provided that has a strip of antenna elements extending in a first dimension, and a signal processing interface for connection to signal processing circuitry. A plurality of beamforming networks are also provided, wherein each beamforming network is arranged, when coupled to the strip of antenna elements, to cause an associated beam pattern of the beamforming network to be generated by the strip of antenna elements. Switching circuitry is used to enable any one of the plurality of beamforming networks to be inserted between the strip of antenna elements and the signal processing interface. Each beamforming network couples a first node of the beamforming network with multiple second nodes of the beamforming network in accordance with a coupling pattern of that beamforming network. As a result, when the switching circuitry causes a given beamforming network to be inserted between the strip of antenna elements and the signal processing interface, the signal processing interface is coupled to the first node, each antenna element is coupled to an associated one of the second nodes, and the coupling pattern of the given beamforming network causes the associated beam pattern to be generated by the strip of antenna elements.

摘要： A cellular communication apparatus includes antenna circuitry. A transceiver receives or transmits a signal using the antenna circuitry on a chosen channel of a portion of a radio spectrum. The portion of the radio spectrum is divided into one or more channels including the chosen channel each occupying a bandwidth of the portion of the radio spectrum. Control circuitry dynamically changes a configuration of the one or more channels of the radio spectrum and communication circuitry communicates the configuration of the one or more channels of the radio spectrum to one or more items of user equipment.
