A method and system of constrained optimization with linear constraints to remove overlap among cells of an integrated circuit. A coarse placement using well known methods may provide an initial placement of cells. Overlapping cells are separated. Any cell moved to its initial placement may be fixed so as not to be moved during subsequent placements. A plurality of linear inequalities representing allowable placements of a plurality of cells of a layout is generated. An objective function measuring cell movement subject to the constraints of the plurality of inequalities is minimized. The objective function minimizes cell movement from the initial cell placement. In this novel manner, large and small cells may be automatically simultaneously placed, deriving speed and quality advantages over prior art methods.

A method and apparatus are provided for receiving system information during inter-cell movement of a user equipment (UE) in a network sharing (NS) system. The UE moves from a previous cell to a new cell. After the movement, the UE compares a public land mobile network (PLMN) identity indicating a PLMN to which the previous cell belongs, with a PLMN identity indicating a PLMN to which the new cell belongs. If the PLMN identity of the new cell is equal to the PLMN identity of the previous cell, the UE sets system information blocks that it has received and stored in the previous cell, as system information of the new cell. If the PLMN identity of the new cell is not equal to the PLMN identity of the previous cell, the UE receives system information blocks with ‘Area scopes Cell and PLMN’ from the new cell, considering that the system information for the previous cell will be invalid in the new cell.
