  • Publication number: 20170041104
    Abstract: A method is provided for performing data transmission using a hybrid automatic repeat request (HARQ) scheme performed by a transmitter. The transmitter transmits uplink data to a receiver, and receives an acknowledgement (ACK) signal for the data from the receiver. The transmitter determines whether or not an uplink grant associated with the ACK signal is received. The transmitter keeps the uplink data in an HARQ buffer of the transmitter without flushing the uplink data if it is determined that the uplink grant associated with the ACK signal is not received within a certain time period from the receiver.

  • Patent number: 9507669
    Abstract: A method of data transmission using HARQ is provided. The method includes transmitting an uplink data, receiving an ACK/NACK signal for the uplink data, keeping the uplink data in a HARQ buffer when the ACK/NACK signal is an ACK signal, and retransmitting the uplink data when an uplink scheduling information for retransmission of the uplink data is received. In the present invention, a transmission error in an ACK/NACK signal is promptly detected, and thus data can be transmitted at a high speed.

  • Patent number: 8984362
    Abstract: A method is described for transmitting signals in a mobile communication system which splits an information block into a plurality of split-information blocks and performs a hybrid automatic repeat request (HARQ) process upon each of the split-information blocks. A method is also described for reducing control information overhead by transmitting control information only through one control channel when splitting an information block and transmitting split-information blocks through a plurality of subframes or a plurality of resource blocks. The segmentation of the information block is performed in a physical layer to reduce medium access control (MAC) overhead and to simplify implementation.
