Abstract: A method for feeding back information includes: measuring a CQI of a link between each coordinated transmitting node in a coordinated transmitting node set and a terminal; using the CQI of and an RI value corresponding to the link between each coordinated transmitting node and the terminal as parameters of a spectral efficiency calculation function, and obtaining a spectral efficiency value corresponding to the link between each coordinated transmitting node and the terminal; when a value of the selection criterion function is less than or equal to a preconfigured comparison threshold value, selecting a corresponding coordinated transmitting node as a preferred coordinated transmitting node; and sending information of the preferred coordinated transmitting node to a transmitting end for selection. This may reduce uplink feedback overheads and enable the transmitting end to quickly determine the preferred coordinated transmitting node.
Abstract translation: 一种用于反馈信息的方法包括：测量协调发射节点集合中的每个协调发射节点与终端之间的链路的CQI; 使用与每个协调发送节点和终端之间的链路相对应的CQI和频谱效率计算功能的参数，并获得与每个协调发送节点和终端之间的链路相对应的频谱效率值; 当选择准则函数的值小于或等于预配置的比较阈值时，选择对应的协调发送节点作为优选协调发送节点; 并将优先协调发送节点的信息发送到发送端进行选择。 这可以减少上行链路反馈开销，并使得发送端能够快速地确定优选的协调发送节点。
