  • Patent number: 9872283
    Abstract: Disclosed are a repeater for receiving signals from a base station in a wireless communication system, and a signal receiving method. The base station reports, to each repeater, information on the aggregation level of a relay-control channel element (R-CCE) of a relay-physical downlink control channel (R-PDCCH) via an explicit signaling method or implicit signaling method. In the event the base station reports via an explicit signaling method, the repeater receives, from the base station, information on the aggregation level of R-CCE which is a transmission unit of R-PDCCH, wherein the information contains control information for the repeater. Then, the repeater decodes an R-PDCCH region on an R-CCE aggregation level basis in accordance with the received R-CCE aggregation level information.

  • Publication number: 20170104519
    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.

  • 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.
