  • Publication number: 20180302146
    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: 20180302203
    Abstract: The embodiments of the present invention relate to a wireless access system supporting an unlicensed band and to methods for generating a discovery signal (DRS), methods for generating and transmitting a channel state information reference signal included in the DRS, and devices for supporting same. The method for transmitting a discovery signal (DRS) including a channel state information reference signal (CSI-RS) in a wireless access system supporting an unlicensed band, according to one embodiment of the present invention, may comprise the steps of: initiating, in subframe n (SF #n), a listen-before-talk (LBT) procedure for checking whether the unlicensed band is idle or not; if an LBT procedure succeeds in SF #n+k, generating a sequence for transmitting the CSI-RS on the basis of the subframe index j indicating SF #j; and transmitting the DRS, including the CSI-RS, in SF #n+k. Herein n, k, and j are preferably integers greater than or equal to 0 and less than or equal to 9.

  • Publication number: 20180302206
    Abstract: A method is provided for transmitting aperiodic channel state information (CSI). A base station (BS) transmits, to a user equipment (UE), receiving a downlink control information (DCI) which includes a CSI request field; and performing aperiodic CSI reporting using a Physical Uplink Shared Channel (PUSCH) when a value of the CSI request field triggers an aperiodic CSI report. In addition, when the CSI request field is a multi-bit field, the CSI request field has a value among a first value which triggers an aperiodic CSI report for a first reference signal and a second value which triggers an aperiodic CSI report for a second reference signal. Furthermore, a resource of the first reference signal and a resource of the second reference signal are configured by a higher layer signal.
