[0039] See also Figure 2 , Figure 2 The present application provides an uplink scrambling code scrambling method, the method comprising: Figure 1 The terminal shown in the figure executes the method, which comprises the following steps:

[0040] Step S201: UE obtains a complex signal of an uplink channel;

[0041] In an optional solution, the uplink channel specifically includes any one or a combination of the following:

[0047] Determine the S as: 1× uplink channel signal, −j× uplink channel signal, j× uplink channel signal or −1× uplink channel signal according to the complex number X+jY of the complex signal and the rotation angle;

[0048] Among them, j is the imaginary part.

[0049] The technical solution provided by the present application is that the UE obtains the complex signal of the uplink channel; the UE adds the uplink scrambling code S dpch,n Rotate the set angle to get S dpch,n ’ UE according to the complex signal and S dpch,n ’ Determine to obtain the output S; when the UE uses the technical solution of the present application to perform scrambling, the output S obtained by rotating the angle will only retain one of the real part or the imaginary part of the complex number X+jY, thereby simplifying the amount of calculation and reducing the computational complexity of uplink scrambling.

[0050] The complex number X+jY of the complex signal is based on the definition of the long scrambling code and the short scrambling code in the protocol. The definition of the long / short scrambling code in the protocol shows that X+jY has only four values: 1+j, 1-j, -1+j, -1-j. The above protocol may be a 3GPP protocol, and the above long / short scrambling code may refer to the definition in 3GPP 4.3.2.

[0055] If the rotation angle is 45° clockwise, X+jY=﹣1+j, then S=j×uplink channel signal;

[0056] If the rotation angle is 45° clockwise, X+jY=-1-j, then S=-1×uplink channel signal.

[0057] In an optional solution, determining S as: 1× uplink channel signal, −j× uplink channel signal, j× uplink channel signal or −1× uplink channel signal based on the complex number X+jY of the complex signal and the rotation angle specifically includes:

[0058] If the rotation angle is 135° clockwise, X+jY=1+j, then S=-j×uplink channel signal;

[0059] If the rotation angle is 135° clockwise, X+jY=1-j, then S=-1×uplink channel signal;

[0060] If the rotation angle is 135° clockwise, X+jY=﹣1+j, then S=1×uplink channel signal;

[0061] If the rotation angle is 135° clockwise, X+jY=-1-j, then S=j×uplink channel signal.

[0062] In an optional solution, determining S as: 1× uplink channel signal, −j× uplink channel signal, j× uplink channel signal or −1× uplink channel signal based on the complex number X+jY of the complex signal and the rotation angle specifically includes:

[0063] If the rotation angle is 225° clockwise, X+jY=1+j, then S=-1×uplink channel signal;

[0064] If the rotation angle is 225° clockwise, X+jY=1-j, then S=j×uplink channel signal;

[0065] If the rotation angle is 225° clockwise, X+jY=﹣1+j, then S=﹣j×uplink channel signal;

[0066] If the rotation angle is 225° clockwise, X+jY=-1-j, then S=1×uplink channel signal.

[0067] In an optional solution, determining S as: 1× uplink channel signal, −j× uplink channel signal, j× uplink channel signal or −1× uplink channel signal based on the complex number X+jY of the complex signal and the rotation angle specifically includes:

[0068] If the rotation angle is 315° clockwise, X+jY=1+j, then S=j×uplink channel signal;

[0069] If the rotation angle is 315° clockwise, X+jY=1-j, then S=1×uplink channel signal;

[0070] If the rotation angle is 315° clockwise, X+jY=﹣1+j, then S=﹣1×uplink channel signal;

[0071] If the rotation angle is 315° clockwise, X+jY=-1-j, then S=-j×uplink channel signal.

[0072] The above-mentioned uplink channel signal may be a single uplink channel signal or a combined uplink channel signal. The combined uplink channel signal is described below with reference to the accompanying drawings.

[0073] See also Figure 3 , Figure 3 A schematic diagram of a combined uplink channel signal. Figure 3 , Figure 3The uplink channel signals in the RAN combine DPCCH, DPDCHs, HS-DPCCH, E-DPCCH and E-DPDCHs.
