For example, have a base station in a communication system, a UE and three RN are respectively RN1, RN2 and RN3.The signal of UE emission is X1, and UE determines sequence index n _oc(n _s) value is 1, determines that according to table 1 corresponding orthogonal sequence is [+1-1+1-1]; The signal of RN1 emission is X2, and RN1 determines sequence index n _oc(n _s) value is 0, the orthogonal sequence of determining according to table 2 is [N N+1+1]; The signal of RN2 emission is X3, and RN2 determines sequence index n _oc(n _s) value is 1, the orthogonal sequence of determining according to table 2 is [N-1+1 N]; The signal of RN3 emission is X4, and RN3 determines sequence index n _oc(n _s) value is 2, the orthogonal sequence of determining according to table 2 is [N-1 N+1].Noise on 4 symbols is respectively n ₁, n ₂, n ₃And n ₄

The base station is respectively at the reception signal of 4 symbols: X1+n ₁, X1-X3-X4+n ₂, X1+X2+X3+n ₃,-X1+X2+X4+n ₄The sequence index n that signal X1 is corresponding _oc(n _s) value is 1, orthogonal sequence [+1-1+1-1] de-spread is used in the base station when separating X1, obtain 4X1+n after de-spread ₁-n ₂+ n ₃-n ₄, can obtain signal X1.The sequence index n that X2 is corresponding _oc(n _s) value is 0, uses [+1+1+1+1] de-spread when separating X2, is 2X2+n after de-spread ₁+ n ₂+ n ₃+ n ₄, can obtain signal X2.The sequence index n that signal X3 is corresponding _oc(n _s) value is 1, uses [+1-1+1-1] de-spread when separating X3, is 2X3+n after de-spread ₁-n ₂+ n ₃-n ₄, can obtain signal X3.The sequence index n that signal X4 is corresponding _oc(n _s) value is 2, uses [+1-1-1+1] de-spread when separating X4, is 2X4+n after de-spread ₁-n ₂-n ₃+ n ₄, can obtain signal X4.

The base station is receiving information that RN sending on R-PUCCH and/or UE after the information that sends on PUCCH, can be according to sequence index n _oc(n _s), determine that according to table 5 corresponding orthogonal sequence carries out despreading to the information that receives.When the orthogonal sequence of determining according to table 5 carried out despreading to the information that receives, method and top method were similar, and just first symbol that receives is not processed in the base station.
