Abstract
A method and apparatus for cell barring in a wireless communication system are provided. The method includes determining whether system information block type 1 (SIB1) is acquired from a cell, considering the cell as barred, if the acquiring the SIB1 fails, determining whether the cell is a licensed cell or an unlicensed cell and excluding the cell and other cells on a same frequency with the cell as a candidate for cell selection or reselection for a pre-defined period, if the cell is a licensed cell and cell selection or reselection to intra-frequency cells is not allowed.
Claims12
A method for cell barring performed by a User Equipment (UE) in a wireless communication system, the method comprising:
- acquiring, from a cell, a master information block (MIB);
- identifying, based on the MIB, that the cell is barred and cell selection or reselection to intra-frequency cells is not allowed;
- identifying whether the cell belongs to a public land mobile network (PLMN) equivalent to a registered PLMN of the UE;
- and
- excluding the cell as candidates for cell selection or reselection for a pre-defined period and considering other cells on a same frequency as the cell as candidates for cell selection or reselection, if the cell does not operate on licensed spectrum and the cell does not belong to the PLMN equivalent to the registered PLMN of the UE.
A User Equipment (UE) in a wireless communication system, the UE comprising:
- a transceiver;
- and
- at least one processor configured to:
- acquire, from a cell, a master information block (MIB),
- identify, based on the MIB, that the cell is barred and cell selection or reselection to intra-frequency cells is not allowed,
- identify whether the cell belongs to a public land mobile network (PLMN) equivalent to a registered PLMN of the UE, and
- exclude the cell as candidates for cell selection or reselection for a pre-defined period and consider other cells on a same frequency as the cell as candidates for cell selection or reselection, if the cell does not operate on licensed spectrum and the cell does not belong to the PLMN equivalent to the registered PLMN of the UE.
