Claim of US Patent No. 9,325,464

1. An uplink transmission method, comprising:
mapping, by a user equipment, complex data symbols obtained by modulation onto Q sub-frames, wherein Q represents a positive
integer;

modulating, by the user equipment, the complex data symbols mapped onto each sub-frame respectively into a transmission signal
corresponding to each sub-frame; and

transmitting, by the user equipment, the transmission signal in corresponding sub-frame;
wherein the mapping, by the user equipment, complex data symbols obtained by modulation onto the Q sub-frames comprises: the
user equipment selecting sequentially and mapping the complex data symbols onto the Q sub-frames; and for a sub-frame, the
user equipment determines complex data symbols to be mapped to the sub-frame by an equation of:

xq(n)=d(q×MsymSF+n),

wherein xq(n) represents a n-th complex data symbol mapped onto a sub-frame q; d(q×MsymSF+n) represents a (q×MsymSF+n)-th complex data symbol; MsymSF represents an amount of complex data symbols mapped onto the sub-frame q; q represents a sub-frame index and q=0, 1, . . .
Q?1; and n represents an index of the complex data symbol mapped to a sub-frame, and n=0, 1, . . . MsymSF?1;

or
wherein the mapping, by the user equipment, the complex data symbols obtained by modulation onto the Q sub-frames comprises:
selecting, by the user equipment, at an interval and mapping the complex data symbols onto the Q sub-frames; and for a sub-frame,
the user equipment determines complex data symbols to be mapped to the sub-frame by an equation of:

xq(n)=d(q+n×Q),

wherein xq(n) represents the complex data symbol mapped onto a sub-frame q; d(q+n×Q) represents a (q+n×Q)-th complex data symbol: MsymSF represents an amount of complex data symbols mapped onto the sub-frame q; q represents a sub-frame index, and q=0, 1, . .
. Q?1; and n represents an index of the complex data symbol mapped to a sub-frame, and n=0, 1, . . . MsymSF?1.
