Title: RADIO BASE STATION AND MOBILE STATIONS
Abstract:
The objective of the invention is to facilitate dealing with mobile stations (UE) and determine a cell for which an RA procedure is to be performed in an sTAG. A radio base station (eNB) comprises an RA procedure executing unit (12) that is configured to: perform an RA procedure in a "DL timing reference cell" if it is determined that the "DL timing reference cell" is existent in an sTAG and that the "DL timing reference cell" has been activated; and perform an RA procedure in a "DL timing reference cell" after the activation of the "DL timing reference cell" if it is determined that the "DL timing reference cell" is existent in an sTAG and that the "DL timing reference cell" has not been activated.
