Abstract
Provided are a terminal apparatus, a base station apparatus, a communication apparatus, a cell selection method, and an integrated circuit in which a cell selection procedure between the mobile station apparatus and the base station apparatus are efficiently performed to improve communication quality. The terminal apparatus determines whether or not a cell detected by the terminal apparatus is suitable for a cell selection candidate on the basis of first cell restriction information indicating cell access restriction that is applied during cell selection, second cell restriction information that is determined by the terminal apparatus whether or not to apply, and a cell measurement result.
Claims9
