Abstract: 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.

Abstract: A node, operable in a wireless network, stores one or more triggers. In response to a trigger 1018, upstream nodes are detected using a scanning process that breaks 1010 a connection with an upstream node. After completion of the scanning process 1014 a connection is made 1017 to one of the upstream nodes. The trigger may be a broken connection with an upstream node, expiration of a timer, or a failure to connect to a preferred upstream node. The scanning procedure may be restricted to times of low usage of the node. The scanning procedure may involve sweeping by physical rotation or beamforming, or scanning several frequency bands. The node may rank upstream nodes based on criteria such as radio frequency properties, and may attempt to connect to the highest ranked node (1013,1015). The upstream node may provide a wireless backhaul and the scanning node may be a relay node.

Abstract: A node that includes means for wirelessly connecting to other devices in a wireless network using either a first radio configuration or a second radio configuration, which may be radio frequency bands, has means for determining a first measurement related to connecting to a device in the first radio configuration, and a second measurement related to connecting to the device in the second radio configuration; means for calculating a metric, for each device, wherein each metric is calculated by applying a first weighting greater than zero to the first measurement obtained for that device and a second weighting greater than zero to the second measurement obtained for that device. Selection circuitry selects one of the other devices in dependence on the metric calculated for each of the other devices. Measurements can include RSRP, SINR, Spectral Efficiency, Rank Index, channel quality, transmission speed and/or dominance values. Optionally, a third measurement relating to a third configuration, such as Wi-Fi, can be obtained. Measurements lacking timing or GPS information, can be disregarded.

Abstract: A method and corresponding apparatus are provided for configuring a wireless network comprising a plurality of nodes to mitigate effects of an external interference source. A subset of nodes of the plurality of nodes are configured to simultaneously participate in an external interference sampling process in which each node of the subset of nodes samples signals received by an antenna array of that node. A measurement report, comprising a signal source angle and a received signal strength, is received from a node. A location of the external interference source is firstly estimated using the measurement report received from the node. The external interference source is then characterised using the estimated location of the external interference source and the received signal strength to calculate for the externalinterference source at least one of: a source power; a beam width; an antenna bearing; and a front-to-back transmission ratio. Finally the plurality of nodes are configured to mitigate the effects of the external interference source in dependence on a result of the characterising step.Characterising the external interference source may comprise performing a characterisation particle filter process using a particle filter algorithm.

Abstract: There is provided a node for use in a network, the node comprising: communication circuitry to communicate with a management server. Bootstrap circuitry initially identifies an intermediate node from at least one available node in the network in response to the communication circuitry being unable to communicate with the management server directly. The communication circuitry is arranged to communicate with the management server indirectly via the intermediate node when unable to communicate with the management server directly. Role assignment circuitry assigns a role to be performed by the node in the network based on whether the communication circuitry communicates with the management server directly, or indirectly via an intermediate node. Embodiments describe use within a wireless feeder network where the nodes may be a Feeder Base Station or Feeder Terminal.

Abstract: An antenna apparatus 300, for use in a wireless network, has omnidirectional antenna elements 302 and RF chains 306, where there are fewer RF chains 306 than omnidirectional antenna elements 302. A subset of the omnidirectional antenna elements 302 are coupled to the RF chains 306 and sampling circuitry 310 coupled to the RF chains 306 samples the signals received by the subset of the omnidirectional antenna elements 302. This forms part of a signal detection process 316 in which different subsets of the omnidirectional antenna elements 302 are iteratively coupled to the RF chains 306. A signal sample spatial covariance matrix 318 for the omnidirectional antenna elements 302 is constructed from the signals sampled by the sampling circuitry 310 at each iteration and a beamforming algorithm 320 applied to the signal sample spatial covariance matrix 318 parameterises the signals received by the omnidirectional antenna elements 302.

Abstract: An antenna configuration system comprises a rotatable antenna assembly configured to employ a transmission beam pattern selected from a plurality of transmission beam patterns; a controller to rotate the assembly to each of a multiple selected azimuth directions; signal quality metric determination means for each of the selected azimuth directions and transmission beam determination means to determine an output beam pattern and an output azimuth direction; the controller being arranged to rotate the antenna apparatus to the output azimuth direction and to employ the output beam pattern for a subsequent communication involving at least one wireless terminal. The assembly may rotate, at regular intervals, through a three hundred and sixty degree range. A level of service priority weighting for at least one wireless terminal may also be used in determining the output azimuth direction and the output beam pattern for a subsequent communication. A weighted harmonic mean process may be used in the system. Extrapolated data may be used in the determining process. The system may be used in a backhaul network coupling to a core network. The system may provide an efficient self configuration arrangement which can establish optimal quality communication links.
