摘要： A method, an apparatus, and a computer program that includes forming frequency hopping position of the sounding reference signal is based on a hopping pattern. The hopping pattern of the sounding reference signal is configured to utilize a tree assignment for a frequency allocation of the sounding reference signal and to support at least one frequency band branch per layer. The hopping pattern of the sounding reference signal is also configured to provide consecutive sounding reference signals on widely separated frequency allocations.

摘要： A reference signal cyclic shift (CS) is quantized as a combination of a cell specific CS with an outcome of a pseudo-random hopping, and an indication of the cell specific CS is broadcast in the cell. In one embodiment the CS is quantized as a modulo operation on a sum of the cell specific CS, the outcome of the pseudo-random hopping, and a user specific CS, in which case an indication of the user specific CS is sent in an uplink resource allocation and a user sends its cyclically shifted reference signal in the uplink resource allocated by the uplink resource allocation. The CS may also be quantized according to length of the reference signal as cyclic_shift_symbol=(cyclic_shift_value*length of the reference signal)/12; where cyclic_shift_value is between zero and eleven and cyclic_shift_symbol is the amount of CS given in reference signal symbols.

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.
