  • 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: 9553655
    Abstract: A method for receiving data by a relay station (RS) in a wireless communication system includes: receiving radio resource allocation information via an R-PDCCH (R-Physical Downlink Control Channel); and receiving data from a base station (BS) via an R-PDSCH (R-Physical Downlink Shared Channel) indicated by the radio resource allocation information, wherein the radio resource allocation information includes information regarding an allocation of resource blocks in a frequency domain and information regarding an allocation of OFDM symbols in a time domain. Since the radio resource allocation information providing information regarding a time relationship between a control channel transmitted by the BS to a UE and a control channel transmitted by the RS to a UE connected to the RS is provided, the RS can reliably receive a signal transmitted from the BS in a backhaul link between the BS and the RS in a wireless communication system including the RS.

  • Patent number: 9538512
    Abstract: Disclosed are an apparatus and a method for transmitting/receiving control information in a wireless communication system. In a repeater according to the present invention, a receiving antenna can receive control information for a hybrid automatic repeat reQuest ACKnowledgement (HARQ ACK) feedback on the data transmission of a base station from the base station through higher layer signaling. On the basis of the control information, a processor can determine a resource in an upper link control channel to be used for the transmission of the HARQ feedback. A transmitting antenna can transmit the HARQ feedback to the base station through the resource that has been determined.

  • 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.
