    摘要: A method and device for transmitting a reference signal in a wireless communication system is provided. A base station maps each demodulation reference signal (DMRS) of each of a plurality of layers into a first resource element (RE) set and a second RE set including four REs over four orthogonal frequency division multiplexing (OFDM) symbols within a subframe, allocates first orthogonal cover codes (OCCs) having a length of 4 to each DMRS mapped into the first RE set, allocates second OCCs having a length of 4 to each DMRS mapped into the second resource element set and transmits each DMRS mapped into the first RE set and the second RE set. The subframe includes two slots and each slot includes six OFDM symbols. The second OCC are formed by swapping positions of bits that constitute the first OCCs.

    摘要: Provided are a method and apparatus for transmitting reference signals in a wireless communication system. A first set of reference signals and a second set of reference signals are generated and mapped to a first resource block (RB) in accordance with a first reference signal pattern and a second RB which is close to the first RB in accordance with a second reference signal pattern. The first RB and the second RB are transmitted from a base station to user equipment. Each of the first reference signal pattern and the second reference signal pattern is formed of one sub-frame and on RB unit. In addition, resource elements (Rs) to which the first set of reference signals and the second set of reference signals are respectively mapped in accordance with the second reference signal pattern are REs to which the second set of reference signals and the first set of reference signals are respectively mapped in accordance with the first reference signal pattern.

    摘要: Disclosed is a method for transmitting a CoMP reference signal for accurate channel estimation. The CoMP reference signal is a cell-specific reference signal or a CoMP-zone-specific reference signal. A method for transmitting the cell-specific reference signal uses a CoMP set ID or does not apply a frequency shift value, or uses a serving cell ID or a frequency shift value of the serving cell. The cell-specific reference signal is transmitted using a preset resource region. A method for transmitting the CoMP-zone-specific reference signal is configured such that the pattern of the sequence of CoMP reference signals varies in each of the CoMP zones, and the pattern can be set in advance. The reference signal is multiplexed using an orthogonal code and transmitted to plural terminals using the same CoMP zone.

    摘要: Provided are a method and apparatus for transmitting a reference signal in a multi-antenna system. A terminal generates a plurality of reference signal sequences in which cyclic shift values different from each other are allocated to the respective plurality of layers, and generates a single carrier-frequency division multiple access (SC-FDMA) symbol to which the plurality of reference signal sequences are mapped. The SC-FDMA symbol is transmitted to a base station via a plurality of antennas. The cyclic shift values allocated to the respective layers are determined on the basis of a first cyclic shift value, which is a cyclic shift value allocated to a first layer from among the plurality of layers, and cyclic shift offsets which are allocated to the respective layers and which are different from each other.
