摘要
A mobile device in a communication system executes transmitting and/or receiving during fixed TTIs. The mobile device receives downlink data transmitted from a base station and indicate whether or not the receipt of the downlink data has succeeded to the base station. In case of an unsuccessful receipt of the downlink data, the mobile device activates reception for a first retransmission of the downlink data which is retransmitted from the base station after a first number of TTIs pass from a TTI in which the downlink data has been received, and in case of an unsuccessful receipt of the first retransmission of the downlink data, the mobile device activates reception for a second retransmission of the downlink data which is retransmitted from the base station after a RTT passes from a TTI in which the first retransmission of the downlink data is received Then the mobile device maintains the reception for the second retransmission of the downlink data activated until receipt of the second retransmission, wherein said a first number of TTIs is equal to one RTT.
