Abstract:
1. A method for frequency hopping of a downlink dedicated pilot frequency, comprising: 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 the downlink dedicated pilot frequency pertains; determining a frequency domain position of the downlink dedicated pilot frequency in a physical resource block to which the downlink dedicated pilot frequency belongs after a frequency hopping according to the frequency hopping offset and a relative frequency domain position of the downlink dedicated pilot frequency; performing resource mapping for the downlink dedicated pilot frequency on the entire frequency domain according to the determined frequency domain position; wherein, if a sum of the relative frequency domain position of the downlink dedicated pilot frequency in the physical resource block and the frequency hopping offset of the downlink dedicated pilot frequency is greater than the number of sub-carriers included in the physical resource block, the frequency domain position of the downlink dedicated pilot frequency in the physical resource block to which the downlink dedicated pilot frequency belongs after a frequency hopping is a frequency domain position obtained by the sum of the relative frequency domain position and the frequency hopping offset of the downlink dedicated pilot frequency modulo the number of sub-carriers included in the physical resource block.
