<p>A method for hopping frequency of public pilots in a long-term evolution system includes the following step: when the frequency hopping of every downlink public pilot in a cell is carried out by a base station, the base station limits the shift of the frequency hopping in the minimum number of the resource elements between two downlink public pilots in one OFDM symbol. The corresponding device includes a frequency domain mapping location calculation module which is used to calculate frequency domain mapping location of the downlink public pilot, a time domain mapping location calculation module used to calculate time domain location of the downlink public pilot and a mapping module used to map the downlink public pilot to a physical resource block. The collision of public pilots on different antenna ports of neighbor cells can be avoided.</p> |
