1. A method for cell reselection by a non-Bandwidth reduced Low complexity (non-BL) wireless device, the non-BL wireless device camped in a standalone cell providing enhanced coverage to the wireless device, the method comprising:
based on a respective signal strength of each of a plurality of cells, determining a first ranking of the plurality of cells, the plurality of cells comprising at least the standalone cell and a target cell;
while the non-BL wireless device is camped in the standalone cell with enhanced coverage, determining that at least one criteria is met for a cell reselection from the standalone cell to the target cell, the target cell offering normal coverage to the wireless device; and
selecting the target cell to camp in whether or not the target cell ranks higher than the standalone cell in the first ranking.
