Abstract: Methods and apparatuses are provided for Channel State Information (CSI) feedback. An Uplink (UL) grant is received from a Node B. Information included in the UL grant is identified. If the information is mapped to at least one DownLink (DL) Component Carrier (CC) based on configuration information relating to at least one set including the at least one DL CC, at least one CSI corresponding to the at least one DL CC is generated. The generated at least one CSI is transmitted to the Node B.

Abstract translation: 为信道状态信息（CSI）反馈提供了方法和装置。 从节点B接收上行链路（UL）授权。识别包括在UL授权中的信息。 如果基于与包括至少一个DL CC的至少一个集合有关的配置信息将信息映射到至少一个下行链路（DL）分量载波（CC）），则生成与至少一个DL CC对应的至少一个CSI 。 所生成的至少一个CSI被发送到节点B.
