摘要： The present invention relates to a method and circuitry for determining a spreading factor in a communication system with variab le data rates. In such a system the received signal n such system may include a plurality of data symbols that are spread in the transmission signal in a manner that is defined by a spreading code and a spreading factor, the spreading factor being one of a plurality of possible spreading factors. In accordance with the method, the received signal is processed so as to produce signal outputs which are cleared from the effects of the spreading code, autocorrelation values are computed for the signal outputs, and the spreading factor is determined based on the computed autocorrela tion values.

摘要： According to an embodiment a user equipment UE transmits uplink control signals using one or more chunks of uplink frequency spectrum that contain a simultaneous uplink shared channel; and for the case where there is no simultaneous uplink shared channel available, the UE transmits uplink control signals using only a single chunk of uplink frequency spectrum. In various embodiments the control signals are ACK/NACK control signals transmitted on an uplink control channel, the uplink shared channel comprises a chunk-specific uplink control channel, and each chunk comprises a component carrier of a LTE-A system. Downlink assignment index bits may be included in a downlink grant to the UE which indicates how many chunks in total are allocated in a current downlink subframe. The UE can also use ACK/NACK control signal bundling over chunks in addition to either or both of chunk-specific ACK/NACK control signals or ACK/NAK control signal multiplexing.

摘要： A detect decision is made by non-coherently combining results from correlating a preamble (CAZAC) sequence with base/root sequences used in the cell and setting a detection threshold based on those combined results. Another threshold can be set based on coherently combining results from correlating the preamble sequence, in which case the detect decision is based on satisfying either one of the thresholds. Where the sequence repeats in the same preamble, the results that are combined are from correlating the first instance of the CAZAC sequence and from correlating the second instance of the CAZAC sequence. Where the sequence does not repeat, different segments of the CAZAC sequence, each less than the whole and not necessarily of the same length, are correlated for a partial correlation on each segment, then the segments are combined and used to set the detection threshold. Detection may be done in stages, adjusting the threshold after the first stage based on comparing the results of non-coherent and coherent combining.
