Method and apparatus for reduced capability terminal to determine intra-frequency cell reselection parameter via system information block 1 in mobile wireless communication system
View Patent ↗A method and apparatus for selecting a NR cell in a mobile communication system are provided. Method for selecting a NR cell includes selecting, by a terminal, a first cell, acquiring, by the terminal in the first cell, a MIB, acquiring, by the terminal in the first cell, a SIB 1 based at least in part on a first information in the MIB, considering, by the terminal, the first cell as barred, performing, by the terminal a first operation group if the SIB 1 received in the first cell does not include a intraFreqReselection and performing, by the terminal a second operation group if the SIB 1 received in the first cell includes the intraFreqReselection and the second intraFreqReselection is set to NotAllowed.
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 Block 1 (SIB 1 ) based at least in part on a first information in the MIB, the first information is the 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 SIB 1 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 for a specific time and reselecting another cell on the same frequency as the first cell if the selection criteria are fulfilled; and
performing, by the terminal a second operation group if the SIB 1 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 for a specific time and excluding another cell on the same frequency of the first cell as a candidate for cell selection/reselection for a specific time,
wherein the selection criteria are related to a received signal strength of the another cell.
2. A terminal in a wireless communication system, the terminal comprising:
a transceiver configured to transmit and receive a signal; and
a controller configured to control the transceiver to:
select, by a terminal, a first cell;
acquire, by the terminal in the first cell, a MIB, the MIB includes cellBarred set to barred;
acquire, by the terminal in the first cell, a SIB 1 based at least in part on a first information in the MIB, the first information is the 4-bit information indicating at least a specific frequency resource and a specific time duration;
consider, by the terminal, the first cell as barred;
perform, by the terminal a first operation group if the SIB 1 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 for a specific time and reselecting another cell on the same frequency as the first cell if the selection criteria are fulfilled; and
performing, by the terminal a second operation group if the SIB 1 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 for a specific time and excluding another cell on the same frequency of the first cell as a candidate for cell selection/reselection for a specific time
wherein the selection criteria are related to a received signal strength of the another cell.
