    摘要: A method for transmitting a signal to a UE by a BS in a wireless communication system is disclosed. The method includes determining a signal transmission scheme for transmitting a signal to the UE, dividing a basic resource allocation unit, if the signal transmission scheme is CoMP transmission, allocating transmission resources to the UE using the divided basic resource allocation unit, and transmitting the signal to the UE through the allocated transmission resources.

    摘要: Disclosed is a method for setting a carrier indication field indicating an element carrier in a multi-carrier system using a plurality of element carriers. The method includes: transmitting a value of a carrier indication field (CIF) and first CIF setting information that indicates a first mapping relationship between element carriers; transmitting downlink control information (DCI) including a carrier indication field; and transmitting a value of a CIF and second CIF setting information that indicates a second mapping relationship between element carriers, wherein the carrier indication field is a field indicating any one of the plurality of element carriers, and at least one element carrier is mapped with the same carrier indication field value in the first and second mapping relationships.

    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 method for transmitting a sounding reference signal from a terminal to a base station in a radio communication system. More specifically, the method comprises the steps of: receiving downlink control information from a base station; checking a flag bit included in said downlink control information; checking an interpretation bit is included in said downlink control information, when said flag bit indicates an uplink; and transmitting an additional sounding reference signal and/or an uplink common channel based on said interpretation bit.

    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.
