Title: METHOD AND APPARATUS FOR GENERATING REFERENCE SIGNAL
Abstract:
A method and apparatus for generating a reference signal. The method comprises: determining a second sequence according to an initial value of the second sequence and a generator polynomial of the second sequence; and mapping the second sequence to a reference signal sequence with a complex modulation symbol; or determining a first sequence according to an initial value of the first sequence and a generator polynomial of the first sequence; determining a Gold sequence according to a mod 2 operation result of the first sequence and the second sequence; and mapping the Gold sequence to a reference signal sequence with a complex modulation symbol. A plurality of reference symbols in a time slot use the same initial value or a plurality of reference symbols in a plurality of time slots use the same initial value, so that the complexity when a terminal uses a reference signal to perform demodulation is simplified, and the randomization characteristic of a reference signal is improved.
