1. the transmission method of a descending pilot frequency, it is characterised in that the method comprises the following steps:

  • Adopt code division multiplexing CDM mode, or adopt the mode of CDM and frequency division multiplexing FDM mixing to transmit dedicated pilot,Wherein, in the resource for transmitting dedicated pilot, undertaken port mapping according to the mapping ruler set and be that described dedicated pilot configures orthogonal sequence, it is mapped in the port set separate configurations orthogonal sequence in different resource, each port is taken to the orthogonal sequence of different orthogonal sequence set for the adjacent sub-carrier transmitting dedicated pilot.
