Disclosed are a method and an apparatus for channel quality estimation in consideration of interference control and coordinated communication in a cellular system. A base station receives an SRS transmitted by a terminal to thus measure received power, and then configures, for the terminal, a CSI process which may measure SINRs for base stations having higher SRS received power. If the terminal feeds back, to the base station, channel quality information for the configured CSI process, the base station determines an SINR and an MCS to be applied to data transmission in consideration of a received CQI and a CoMP transmission scheme, and applies the determined SINR and MCS to thus transmit data. 公开了蜂窝系统中考虑干扰控制和协调通信的信道质量估计方法和装置。基站接收由终端发送的SRS，从而测量接收功率，然后为所述终端配置CSI过程，所述CSI过程可以为具有较高SRS接收功率的基站测量SINR。如果所述终端向所述基站反馈对于所述配置的CSI过程的信道质量信息，则所述基站考虑所接收的CQI和CoMP发送方案来确定将要应用于数据发送的SINR和MCS，并且应用所确定的SINR和MCS从而发送数据。
