One kind of method and apparatus for generating pilot sequences

The present invention discloses a method for generating pilot sequences, comprising: in each of the code-division with frequency division and / or demodulation reference symbol time-division multiplexed mixing (DMRS) ports, code division multiplexing different groups according to different the criteria for selecting the orthogonal cover (OCC) OCC collection, and / or different code division multiplexing DMRS scrambling sequence group generation according to different criteria; OCC with the selected scrambling sequence generated by multiplying each DMRS the final pilot sequences port. The present invention also discloses a device for generating a pilot sequence. By the methods and apparatus of the present invention, it is possible to reduce the correspondence between the different code division multiplex layer port group, and reducing the frequency shift due to the Doppler Effect on the channel estimation problem of inter-carrier interference caused by timing errors, to improve the estimation accuracy of the channel .
