Abstract: An SAE/LTE or 4G cellular telecommunications network is disclosed which comprises a plurality of eNodeBs and a network core. A plurality of mobile telecommunications devices are registered with the network and communicate with the network core via the eNodeBs. A relay is provided between the eNodeB 5 and the mobile telecommunications device to extend the radio coverage provided by the eNodeB. Channel quality measurement data are transmitted to at least one of the telecommunications devices in a link with the relay to enable the telecommunications devices to calculate the channel quality between the mobile device and the relay and/or the node.

Abstract: In a cellular communication system a first and a second set of antennas are arranged at an antenna site. First and second baseband processing blocks are coupled to the antennas of the first and second antennas respectively. To improve the connection to a terminal an antenna of the second set is coupled to the first baseband processing block in addition to the antennas of the first set. Communication with the terminal is performed via at least one antenna of the first and at least one antenna of the second set. The first and second set of antennas can belong to two different network operators. By applying this invention, the two network operators can share the antenna pool of the first and second set of antennas even if the antennas are the existing ones at the same top-roof or tower.

Abstract: Controlling interference in a telecommunications network, in which data are transmitted between mobile devices and base stations in resource blocks, includes, for each of the base stations: allocating resource blocks to one of multiple resource groups, the corresponding resource blocks of each base station being in the same resource group; allocating resource groups to one of multiple transmission power values, the corresponding resource groups of each base station having different transmission power values; and allocating respective ones of the mobile devices to one of the resource groups depending upon a UE characteristic. Interference at a resource block of a resource group of a base station caused by a neighboring base station is detected. In response thereto, an indication of the resource group subject to interference is sent to the neighboring base station and then the transmission power value of said resource group of the neighboring base station is selectively reduced.

Abstract: A mobile telecommunications device includes cellular communication means for communicating with a cellular telecommunications network base station, wireless communication means for communicating with a wireless access point, and control means for selectively enabling the wireless communication means in response to a trigger. The trigger may be the launch of a web browser of a request for a download of data.

Abstract: A method of operating a mobile telecommunications device 1 including cellular communication means operable to communicate with a cellular telecommunications network base station 3 and white space communication means operable to communicate with a non-cellular white space access point 33, the method including determining the availability of white space and selectively enabling white space communication in dependence upon the determination. Controlling transmission of user data in the white space may be by exchanging control data with the cellular telecommunications network base station 3 such that the control data controls the transmission of user data in the white space. White space communication need not be implemented in uplink and may be used in the downlink alone.
