    摘要: A method and apparatus for channel estimation for radio link between a base station and a relay station in a radio communication system are disclosed. A method for receiving a downlink signal at a relay node in a wireless communication system, the method comprising receiving downlink control information by demodulating a R-PDCCH of a first RB pair based on a downlink channel estimated by a DMRS in the first resource block (RB) pair; and receiving downlink data by demodulating a PDSCH of the one or more RB pairs contiguous to the first RB pair based on a downlink channel estimated by a DMRS in the one or more RB pairs, wherein, if the PDSCH is assigned to the first RB pair, the downlink channel is estimated on the assumption that the same precoder is applied to one RB bundle including the first RB pair and the one or more RB pairs.

    摘要: An apparatus and method for generating a codebook in a wireless communication system are disclosed. The codebook generation method includes determining one or more dominant singular vectors in a channel matrix for antennas and setting each of the dominant singular vectors as a random non-zero vector, generating a first codebook having codewords, a minimum distance between the code-words being maximized, using the random non-zero vector in a region that includes unit norm vectors each having a Euclidean distance to each of the dominant singular vectors, equal to or less than a predetermined value, generating a second codebook corresponding to a unitary matrix that rotates the random non-zero vector toward the dominant singular vectors, and generating a final codebook using the first and second codebooks.

    摘要: An apparatus and method for transmitting and receiving a demodulation reference signal (DM RS) are disclosed. A method for controlling a base station (BS) to transmit a demodulation reference signal (Demodulation RS or DM RS) in a wireless communication system includes transmitting, by the base station (BS), a DM RS for a relay node (RN) to the relay node (RN) through a specific backhaul subframe to which an extended cyclic prefix (CP) is applied. The DM RS is transmitted over two resource elements (REs) of individual subcarriers having subcarrier frequency indexes 2, 5, 8 and 11 in a frequency axis within a second slot of the specific backhaul subframe.

    摘要: A method of decoding a backhaul downlink signal of a relay station is provided. The method includes: receiving by the relay station a transmission rank value for a backhaul downlink from a base station through a high-layer signal; receiving control information from the base station through a control region; and decoding the control information, wherein the transmission rank value for the backhaul downlink is a transmission rank value assumed when the relay station decodes the control information, and wherein the control information is mapped to a resource element which does not overlap with a dedicated reference signal resource element mapped to the control region by assuming the transmission rank value for the backhaul downlink.
