    • The present invention relates to a wireless communication system, and more particularly, discloses a method and a device for transmitting/receiving channel state information in a wireless communication system supporting multicarriers. The method for transmitting downlink channel state information in the wireless communication system supporting downlink multicarriers, according to one embodiment of the present invention, comprises the following steps: receiving from at least one downlink carrier an uplink grant downlink control information (DCI) including a request for the channel state information; measuring the channel state information of at least one first type downlink carrier; and transmitting the measured channel state information on a physical uplink shared channel (PUSCH) resource indicated by the uplink grant DCI, wherein the downlink multicarriers comprise the first type downlink carrier and a second type downlink carrier, wherein the channel state information on the second type downlink carrier may not be transmitted.
    • 本发明涉及一种无线通信系统,更具体地说,涉及一种在支持多载波的无线通信系统中发送/接收信道状态信息的方法和装置。 根据本发明的一个实施例,在支持下行链路多载波的无线通信系统中发送下行链路信道状态信息的方法包括以下步骤:从至少一个下行链路载波接收包括请求的上行链路授权下行链路控制信息(DCI) 用于信道状态信息; 测量至少一个第一类型下行链路载波的信道状态信息; 以及由上行链路许可DCI指示的物理上行链路共享信道(PUSCH)资源发送测量的信道状态信息,其中下行链路多载波包括第一类型下行链路载波和第二类型下行链路载波,其中,关于第二类型的信道状态信息 下行链路载波可能不被发送。
