摘要： The invention relates to a method in a first communication device of receiving control information over a radio channel from a second communication device. The first communication device receives a subframe over the radio channel, and determines whether the subframe is a downlink subframe with downlink assignment intended for the first communication device by reading data in the subframe. That being the case, the first communication device decodes data within the subframe, and determines whether any data packet being sent from the second communication device before the subframe has been missed by analyzing an indicator associated to the subframe in the data. The indicator provides knowledge about previous downlink subframes with downlink assignment intended for the first communication device.

摘要： Timing parameters and an identity of a particular one of a number of cell groups are indicated in a signal transmitted in a cellular communication system having a radio frame in a physical layer, the radio frame comprising a number of time slots. In a known one of the time slots, a synchronization signal, S1, is transmitted that comprises a pair of sequences arranged in a first ordering. In another known one of the time slots, a synchronization signal, S2, is transmitted that comprises a pair of sequences arranged in a second ordering. The selected pair of sequences is uniquely identified with the particular cell group, and the first ordering of the sequences is used only for transmission in the known one of the time slots, and the second ordering of the sequences is used only for transmission in said another known one of the time slots.

摘要： A receiver separates multiple component signals carried in a composite signal that have been spread over time and frequency. Multiple diversity branches receive the composite signal. A tensor generation circuit arranges samples of that signal along time, frequency, and diversity dimensions to obtain a composite signal tensor. A set of cascaded least squares estimators then separates the component signals by fitting a constrained tensor model of the composite signal to the composite signal tensor in an alternating least squares estimation process, alternating during any given iteration of the process between fitting different unfolded representations of the constrained tensor model to corresponding unfolded representations of the composite signal tensor. The tensor model models the composite signal as a linear combination of rank-one tensors associated with the component signals, and is constrained in the sense that each rank-one tensor remains constrained according to the spreading of its associated component signal over time.

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 by user 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.
