Mechanisms addressing dynamic component carrier change in relay systems


The present invention proposes methods and devices to further improve relay systems operating on the basis of carrier aggregation on the access as well as on the backhaul link under an aspect of such approach, there is proposed a relay node as a device, comprising a transceiver device, configured to communicate via a first interface with a terminal and via a second interface with a remote network device, wherein communication via the first and/or second interface is configured to operate based on aggregation of plural individual component carriers, and a control device, configured to perform, per component carrier: detection of a change concerning a component carrier on the first interface, sending, responsive thereto, of update information pertaining to at least the first interface towards the remote network device, reception of reconfiguration instructions, implied by the detected change, to be applied on the first interface, and initiation of reconfiguration of the first interface based on the received instructions. Similar approach is applied to a donor enb as well as to corresponding methods and computer program products..

Antennae system


Embodiments of the invention relate to wireless communications networks, and more specifically to an antenna apparatus for cellular wireless systems. Increasing data capacity of cellular wireless systems places increasing demands on the capacity of the two way connection, known as backhaul, between a cellular base station and a telecommunications network such as the pstn backhaul, since this is the connection that has to convey the wireless-originating traffic to its destination, often in an entirely different network.

Inter-cell power control in the presence of fractional frequency reuse


System(s) and method(s) are provided for inter-cell power control in the presence of fractional frequency reuse in a wireless communication system. Transmission power control of a terminal, and ensuing inter-cell interference mitigation, is accomplished by receiving load indicators from non-serving sectors, decoding those load indicators corresponding to the non-serving sectors that operate in the same frequency bands as the terminal, and adjusting the transmission power according the states of the decoded load indicators in conjunction with the associated non-serving sectors' forward link signal-to-interference-and-noise ratio at the terminal.
