Abstract: A frequency error correction scheme applicable in a receiver of a mobile telecommunication system is presented. The present frequency error correction scheme is carried out in a time domain after an equalization process. The present frequency error correction scheme may be applied to a base station receiving signals transmitted according to a single-carrier frequency division multiple access communication scheme. The separation of different received signals for further processing is carried out in the frequency domain before the equalization and the frequency error correction.

Abstract: A method and a communication bus are provided having nodes. Each of the nodes includes a transmitting element to transmit data to another node on the bus, and a receiving element to receive information from another node on the bus. A communication channel is between the transmitting and receiving elements within each node, a transmitter state machine logic controls the synchronisation of the transmitting element, and a receiving state machine logic to control the synchronisation of the receiving element. A storage area maintains the status of synchronisation of the bus. Communication data is synchronised via a bus connecting first and second nodes. A plurality of encoded bytes, each encoded byte represented as a 10 bit code, is transmitted from the first node. The second node receives and decodes the bytes, where any decoding errors in a byte are detected. A synchronised status is indicated.

Abstract: An approach is provided for cell selection or reselection in a multi-radio network environment involving at least two different radio access technologies. A service preference information which indicates service preferences for different radio access technologies can be set at a network element and be sent to at least one terminal device. At the terminal device, the service preference information is detected and a serving cell is selected based on the detected service preference information. Thereby, the network is capable of performing service-based control of cell selection or reselection of the terminal device upon initiating access for a certain service in an overlaid multi-RAT environment. This in turn enhances network utility, operation and performance.
