1. A method carried out by a user equipment, comprising the steps of:
(a) obtaining a physical layer identifier of a service cell to which the user equipment corresponds;
(b) reading, in accordance with the physical layer identifier thus obtained, a physical resource block PRB corresponding to a physical broadcast channel PBCH;
(c) obtaining a PBCH sequence by carrying out demodulation with use of a demodulation reference signal DMRS; and
(d) obtaining system information of a service cell by decoding a bit contained in the PBCH sequence,
the PRB including a distributed PRB frequency division multiplexing format or a centralized PRB frequency division multiplexing format.
