Abstract: The present disclosure relates to a method for reporting channel state information, a user equipment, and a base station. A channel state information measurement resource is determined by a UE according to an aperiodic CSI trigger signaling, so that a base station transmits a CSI-RS only when the UE needs to report the aperiodic CSI. Compared with transmitting a periodic CSI-RS by an existing base station, unnecessary transmitting of the CSI-RS is reduced, and energy of the base station such as an eNB is saved; and reducing the CSI-RS transmission may reduce resources occupied by the CSI-RS, thereby improving the spectrum efficiency of the system. In addition, reducing unnecessary CSI-RS transmission allows the interference in other cells by the base station being reduced; finally, CSI measurement resources are reserved only when the CSI needs to be fed back, the cost occupied by the CSI measurement resources is reduced.
Abstract translation: 本公开涉及用于报告信道状态信息的方法，用户设备和基站。 信道状态信息测量资源由UE根据非周期性CSI触发信令确定，使得仅当UE需要报告非周期性CSI时，基站才发送CSI-RS。 与现有基站发送周期性CSI-RS相比，减少了CSI-RS的不必要的发送，节省了诸如eNB的基站的能量; 减少CSI-RS传输可能会减少CSI-RS占用的资源，从而提高系统的频谱效率。 此外，减少不必要的CSI-RS传输允许基站的其他小区的干扰减少; 最后，CSI测量资源只有在需要反馈的情况下才被保留，CSI测量资源占用的成本就会降低。
