    摘要: Radiocommunication systems, methods and terminals are described wherein metrics associated with MLSE detecting techniques, e.g., using the Viterbi algorithm, are accumulated in a manner which is less computationally intensive than conventional techniques. The delta metrics associated with each state are partitioned into, for example, six different terms. These terms are then selectively accumulated in phases, before decisions, during decisions and after decisions, to reduce the total number of computations associated therewith. Additionally, certain symmetries associated with exemplary modulations are taken into account in order to further simplify processing and memory requirements of these detecting techniques.

    摘要: A method, User Equipment (UE), and first base station serving a first cell for performing an access request by the UE for operatively connecting the UE to a second cell. The UE obtains radio quality parameters indicating quality of radio reception between the UE and the first and second cells. Based on the obtained radio quality parameters, it is determined whether the UE is in a link imbalance zone where the UE has an option to be connected to both the first cell and the second cell. If so, the UE sends access request information, to the first base station and indicates availability of the UE to be redirected to the second cell. The first base station may redirect the UE to the second cell when a load of the first cell meets pre-defined load criteria.

    摘要: The present invention provides, inter alia, a method of operation of a radio base station in a wireless telecommunications system, in which system information is transmitted on a broadcast control channel. The method comprises the steps of transmitting the broadcast control channel continuously on a first carrier; and also transmitting the broadcast control channel non-continuously and periodically at regular intervals. This prevents or at least minimizes, for example, MBMS data loss when a UE with a single receiver listens to a dedicated MBMS carrier.

    摘要: Physical downlink channels PPHY1, PHY2 are summed in a summation unit 10. The output of summation unit 10 is forwarded to another summation unit 12, where it is combined with the primary and secondary synchronization channels P-SCH, S-SCH. The secondary synchronization channel S-SCH is formed as in WCDMA. The primary synchronization channel P-SCH is formed by connecting a switch SW either to a code generator 14 generating the conventional code PSCWCDMA or a code generator 18 generating the code PSCNEW. The selection is controlled by a PSC controller 18. This controller can be adapted to produce a P-SCH in accordance with one of several formats. PSCNEW has the properties that it is a hierarchical Golay sequence constructed by a plurality of constituent sequences with at least one of the constituent sequences being the Golay sequence, and that it is orthogonal to the primary and secondary synchronization codes used in non-MBSFN capable WCDMA.

    摘要: Systems and methods for processing a received radio signal in a communication system are described. Initial time synchronization is acquired using a trace operator. Then, a number of channel taps for use in further processing is determined based on the initial time sync, also using a trace operator. A final synchronization position is then selected using the number of channel taps and, if multiple branches are employed to receive the signal, using a determinant-based technique. Finally, a channel estimate is determined using the final synchronization position.
