Abstract
A method for frequency hopping of a downlink dedicated pilot frequency, comprises: for the downlink dedicated pilot frequency, determining a frequency hopping offset corresponding to the downlink dedicated pilot frequency according to a cell identity of a cell to which it pertains (S202); determining a frequency domain position of the downlink dedicated pilot frequency in a physical resource block to which it belongs after a frequency hopping according to the frequency hopping offset and a relative frequency domain position of the downlink dedicated pilot frequency (S204); performing resource mapping for the downlink dedicated pilot frequency on the entire frequency domain according to the determined frequency domain position (S206). A base station is used to implement the frequency hopping of the downlink dedicated pilot frequency.
