  • Publication number: 20170048043
    Abstract: A method and a user equipment (UE) for transmitting an aperiodic sounding reference signal (SRS) in a wireless communication system are discussed. The method according to an embodiment includes receiving an aperiodic SRS power offset parameter for the aperiodic SRS from a base station (BS) through a radio resource control (RRC) signaling; receiving common parameters for SRSs, including the aperiodic SRS, from the BS through the RRC signaling; setting a transmission power of the aperiodic SRS based on the aperiodic SRS power offset parameter and the common parameters; and transmitting the aperiodic SRS to the BS based on the transmission power of the aperiodic SRS. The aperiodic SRS power offset parameter is a non-common parameter used for transmitting the aperiodic SRS but not a periodic SRS which is included in the SRSs.

  • Patent number: 9554374
    Abstract: The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for transmitting acknowledgement/negative ACK (ACK/NACK) in a wireless communication system which supports carrier aggregation, and to an apparatus for the method. A method in which a terminal transmits ACK/NACK in a wireless communication system that supports carrier aggregation comprises the following steps: receiving one or more physical downlink shared channels (PDSCHs); and transmitting ACK/NACK for said one or more PDSCHs via a physical uplink control channel (PUCCH). A PUCCH format for transmitting ACK/NACK is selected by taking the type of the carrier in which said one or more PDSCHs are received into account.

  • 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.
