    摘要: A method and apparatus of transmitting a reference signal in a wireless communication system is provided. Demodulation Reference Signals (DMRSs) for a plurality of respective antennas is generated. The DMRSs are mapped to a resource region, and transmitted through the respective corresponding antennas. The DMRSs are multiplexed using at least one of frequency division multiplexing (FDM), code division multiplexing (CDM), and time division multiplexing (TDM) methods and mapped in the resource region. Also, a position of an orthogonal frequency division multiplexing (OFDM) symbol to which the DMRSs are mapped in the resource region is an OFDM symbol to which a physical downlink control channel (PDCCH) and a legacy cell-specific reference signal (CRS) are not mapped.

    摘要: A method and apparatus of transmitting a reference signal in a time division duplex (TDD) system is provided. A base station (BS) generates a plurality of demodulation reference signals (DMRSs) for respective layers, maps the plurality of DMRSs to a downlink pilot time slot (DwPTS) region for downlink transmission within a special subframe; and transmits the plurality of DMRSs through a plurality of antennas. The special subframe is a subframe for separating uplink and downlink between an uplink (UL) subframe and a downlink (DL) subframe within a frame.

    摘要: Disclosed is a method in which a relay node transmits/receives signals via a specific downlink subframe and a specific uplink subframe. The relay node may consider the propagation delay in accordance with the distance between a base station and the relay node to set a subframe timing for transmitting/receiving signals to/from the base station. The relay node may further consider the delay time of 0.5 symbol, 1 symbol or the like in addition to said propagation delay in the event of setting a downlink receiving timing. Setting an uplink subframe timing of the relay node can be divided into the event the timing is set on the basis of a backhaul link and the event the timing is set on the basis of an access link. In the event thee timing is set on the basis of the access link, the propagation delay can bee double that of the vent the timing is set on the basis of the backhaul link, which should be considered in setting the timing.

    摘要: A method for multiplexing one or more multiple access regions is disclosed. The method for multiplexing one or more multiple access regions in a wireless access system comprises multiplexing the one or more multiple access regions so that a first base station and a second base station among a plurality of base stations which use one or more multiple access schemes together under a multi-cell environment use a single multiple access scheme in a predetermined resource region allocated to each of the first base station and the second base station; and transmitting multiplexing information obtained from the multiplexing the one or more multiple access regions to a mobile station included in a cell region of the plurality of base stations. As a user uses SC-FDMA scheme and OFDMA scheme together, it is possible to obtain a single carrier effect of the SC-FDMA system and flexibility of the OFDMA system on a time axis and a frequency axis.
