    摘要: Disclosed are a method and device for transmitting a reference signal in a wireless communication system. 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 resource element set including four resource elements 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 said first resource element set; allocates second OCCs having a length of 4 to each DMRS mapped into said second resource element set; and transmits each DMRS mapped into said first resource element set and said second resource element set. Said subframe includes two slots, and each slot includes six OFDM symbols. Said second OCC are formed by respectively swapping positions of bits that constitute said first OCCs.

    摘要: The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and apparatus in which a base station transmits a signal to a relay in a wireless communication system. A method in which a terminal receives a downlink signal in a wireless communication system that supports carrier aggregation comprises: a step of receiving, on a first carrier, a physical downlink control channel (PDCCH) having no carrier indication information; and a step of receiving a physical downlink shared channel (PDSCH) using the scheduling information carried on the PDCCH, wherein the PDSCH is received on the first carrier in the event the PDCCH is a non-semi-persistent scheduling (SPS) PDCCH, and the PDSCH is received on a second carrier different from the first carrier in the event the PDCCH is an SPS PDCCH.

    摘要: Disclosed is a communication method in a multi-carrier system, including: allocating radio resources for transmitting signals to a middle guard band; and transmitting the signals through the radio resources; wherein the middle guard band is a frequency band positioned between used bands of a plurality of carriers, respectively, within an aggregated carrier formed by aggregating the plurality of carriers and a unit allocating the radio resources of the middle guard band is different from a unit allocating the radio resources of the used bands. A multi-carrier system uses the guard bands between the carriers to improve channel estimation performance or increase efficiency of radio resources.
