Abstract
A method, apparatus and system for downlink pilot transmission solve the problem of power differences among OFDM symbols caused by Walsh codes. The transmission method is that dedicated pilots are transmitted in the manner of code division multiplex (CDM) or hybrid of CDM and frequency division multiplex (FDM), wherein the dedicated pilots are configured with orthogonal sequence sets according to a preset frequency-domain granularity and rules on the resources for transmitting the dedicated pilots, and the same orthogonal sequence set is employed for the dedicated pilots in each frequency-domain granularity.
