Abstract: To avoid reference symbol collision, between reference symbols used by neighboring cells in an OFDM based cellular telecommunications network, the transmission symbols on a given subcarrier used by respective neighboring base stations are compared and where both transmission symbols are determined to be reference symbols the start time of the frame timing period of one of the base stations is adjusted.

Abstract: In a telecommunications network including a mobile terminal and a base station associated with a plurality of antennas, with each antenna configured to transmit the signal with a time offset relative to the other antenna or antennas, an engine for controlling a signal to be transmitted wirelessly from the base station towards the mobile terminal, the engine being configured to receive one or more parameter measurements relevant to the mobile terminal; and use the one or more parameter measurements to adjust the time offset of at least one of the antennas in order to adapt the signal transmission dependent upon the mobile terminal's instantaneous circumstances. Ideally the engine is configured to receive the one or more parameter measurements relating to a plurality of different mobile terminals, and independently adjust the time offset for each of the plurality of different mobile terminals, depending upon the one or more applicable parameter measurements.

Abstract: A mobile telecommunications network includes a core and a radio access network having radio means for wireless communication with mobile terminals registered with the network, wherein the radio access network includes control means 700 operable to control the use of network resources by the mobile terminals. The control means processes control plane signalling.

Abstract: A radio network control method that allows uplink signals transmitted by a mobile station to be received by two or more selected base station radio systems and then combined, thus providing receiver diversity. The method requires measurement of radio link qualities of the OFDM signals passing between mobile station and base station radio system. The method is selectively applied to individual mobile stations and for each mobile station to a selection from the available base station radio systems—the selection being based upon the relative and/or absolute measurements of radio link qualities.
