Abstract:
A mobile station (UE) is configured to establish uplink synchronization with a radio base station (eNB). The mobile station (UE) is configured not to return transmission acknowledgment information for downlink data until receiving a command for adjusting uplink transmission timing, when the radio base station (eNB) allocates a radio resource for transmission of the downlink data to the mobile station (UE).
