  • Patent number: 10193614
    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: 9883493
    Abstract: A method and device for transmitting a power headroom report (PHR) by a user equipment (UE) in a communication system supporting a plurality of carriers. The method includes transmitting, to an eNode B (eNB), a power headroom report (PHR) related to the plurality of carriers configured for the UE. The power headroom report (PHR) comprises a first type power headroom (PH) and a second type power headroom (PH). While the first type power headroom (PH) is calculated for a power headroom report (PHR) related to a primary carrier and a non-primary carrier, the second type power headroom (PH) is calculated for a power headroom report (PHR) related to only the primary carrier. The second type power headroom (PH) is calculated for case of simultaneous transmission of a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH).

  • 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.
