摘要： The present invention relates to methods and arrangements for assisting a User Equipment (UE) to determine transmit power to be used on a first uplink component carrier y, wherein the base station is configured to communicate with the UE over a plurality of uplink and downlink component carriers x,y. The UE is aware of path loss parameters associated with a second downlink component carrier x. The method in a base station comprises determining cell specific path loss parameters associated with the component carriers of the base station. The cell specific path loss parameters at least comprises path loss parameters associated with the first uplink component carrier y and a second uplink component carrier x which is paired to the second downlink component carrier x, wherein the second uplink component carrier and second downlink component carrier are within one frequency band. The method comprises the further steps of calculating a pathloss offset, deltaPL(y,x), for the first uplink component carrier y, wherein the pathloss offset deltaPL(y,x) is the pathloss power offset for the first uplink component carrier y with respect to the second uplink component carrier x, and sending the calculated pathloss offset, deltaPL(y,x) to the UE.

摘要： The invention is a method and apparatus for signaling uplink control information in a mobile communication network using carrier aggregation. The signaling mechanism allows the transmission, on a single uplink component carrier, of control information associated with a downlink transmission on multiple aggregated downlink component carriers. Semi-statically reserved resources for the transmission of control information on the uplink component carrier may be dynamically shared byuser terminals that are assigned multiple downlink component carriers for downlink transmissions. Implicit or explicit resource indication can be used in combination with dynamic resource indication.

摘要： A method, User Equipment, UE, (700), and first base station (800) serving a first cell (140) for performing an access request by the UE tor operatively connecting the UE to a second cell (110). The UE (700) 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 (148) where the UE has an option to be connected to both the first cell (140) and the second cell (110). If so, the UE sends access request information, to the first base station (800) and indicates availability of the UE to be redirected to the second cell. The first base station (800) may redirect the UE to the second cell (110) when a load of the first cell ( 140) meets pre-defined load criteria.

摘要： The present invention is directed toward an automatic frequency control system for compensating for frequency offset of received data signals in a radio frequency communication system. A reference sample index for the data to be compensated is first determined as a function of the transmission channel and known training data. A scaled phase error estimate is calculated along with a time-varying filter parameter. From the scaled phase error estimate and the filter parameter, a frequency offset estimate and a phase drift estimate are calculated. The system proceeds through the time-indexed, received data signals until the entire received batch of data signals has been processed, and the corresponding compensated soft data has been output.

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： 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.

摘要： A first base station provides radio communication service to user equipments, UEs, and a second base station that provides radio communication service to UEs in adjacent cell service area. The first base station receives cell range expansion, CRE, information from the second base station for expanding the size of the first cell and evaluates handover of one or more UEs with respect to the second cell based on the CRE information. In one embodiment, the second base station determines a CRE related configuration that includes the CRE information with respect to the first cell, sends the CRE information to the first base station. For example, the second base station may send a handover request including the CRE information to the first base station. The second base station also may consider CRE information in handover evaluation. In one example implementation, the first base station has a lower output power than the second base station, and the service area of the first cell is smaller than the service area of the second cell.
