1. A method comprising:
selecting, by a terminal, a first cell;
acquiring, by the terminal in the first cell, a Master Information Block (MIB), the MIB includes cellBarred set to barred;
acquiring, by the terminal in the first cell, a System Information Block1 (SIB1) based at least in part on a first information in the MIB, the first information is a 4-bit information indicating at least a specific frequency resource and a specific time duration;
considering, by the terminal, the first cell as barred;
performing, by the terminal a first operation group if the SIB1 received in the first cell does not include a intraFreqReselection, the first operation group includes excluding the first cell as a candidate for cell selection/reselection and reselecting another cell on the same frequency as the first cell if selection criteria are fulfilled; and
performing, by the terminal a second operation group if the SIB1 received in the first cell includes the intraFreqReselection and the intraFreqReselection is set to NotAllowed, the second operation group includes excluding the first cell as a candidate for cell selection/reselection and excluding another cell on the same frequency of the first cell as the candidate for cell selection/reselection,
wherein the selection criteria are related to a received signal strength of the another cell.
