The present invention provides a method carried out by a base station, including: a step (S320) of generating a code sequence containing system information of the base station; a step (S330) generating, by modulating the code sequence, a physical broadcast channel (PBCH) sequence including a distributed PRB frequency division multiplexing format or a centralized PRB frequency division multiplexing format; a step (S340) of selecting a physical resource block (PRB) for a PBCH contained in the PBCH sequence; and a step (S350) of carrying out mapping between the PBCH and a resource element (RE) in the PRB thus selected. The present invention also provides (i) a method carried out by a user equipment, (ii) a corresponding base station, and (iii) the corresponding user equipment. According to the present invention, it is possible to increase energy use efficiency of an LTE-Advanced system, improve spectral efficiency, and reduce inter-cell collision of time/frequency resources. |
