    • 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.

    • The present invention provides a method and apparatus for performing a HARQ in a wireless communication system. In the method for performing a HARQ according to the present invention, a terminal transmits an uplink data over a PUSCH (Physical Uplink Shared Channel); and receives an ACK/NACK (Acknowledgement/Non-Acknowledgement) signal over a Physical Hybrid-ARQ Indicator Channel (PHICH) corresponding to the PUSCH, with the signal indicating whether the uplink data is received through a plurality of layers. Here, downlink resources to which a PHICH is mapped for each of the plurality of layers do not overlap each other. Those downlink resources to which a PHICH is mapped for each of the plurality of layers can be determined based on different cyclic shift values that are allocated to the plurality of the layers, respectively.
    • 本发明提供一种用于在无线通信系统中执行HARQ的方法和装置。 在根据本发明的用于执行HARQ的方法中,终端通过PUSCH(物理上行链路共享信道)发送上行链路数据; 并通过与PUSCH相对应的物理混合ARQ指示符信道(PHICH)接收ACK / NACK(确认/不确认)信号,该信号指示是否通过多个层接收上行链路数据。 这里,对于多个层中的每一个映射了PHICH的下行链路资源彼此不重叠。 可以基于分配给多个层的不同的循环移位值来确定向多个层中的每个层映射PHICH的下行链路资源。

    • 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.
