1. A method performed by a wireless device, the method comprising:
obtaining information that identifies one or more random access channel pre-compensation features required for the wireless device to select a cell, wherein the information indirectly identifies the one or more random access channel pre-compensation features required for the wireless device to select the cell by identifying one or more random access channel pre-compensation features for which the wireless device is not permitted to select the cell;
making a decision as to whether the wireless device is permitted to select the cell based on the information and one or more random access channel pre-compensation features supported by the wireless device; and
performing an action in accordance with the decision, wherein the action is selected from one of the following actions:
selecting or reselecting to the cell for which the decision was made, if the decision is that the wireless device is permitted to select to the cell; or
refraining from selecting or reselecting to the cell for which the decision was made, if the decision is that the wireless device is not permitted to select to the cell.
