<p>A method and a device for feeding back a signal to interference plus noise ratio are provided, which can use a CQI to effectively feed back an SINR. An embodiment of the present invention provides a method for feeding back a signal to interference plus noise ratio, including: obtaining a data transmission mode, a resource utilization mode, or a user equipment type for performing data transmission; determining a CQI table or CQI section corresponding to the data transmission mode, the resource utilization mode, or the user equipment type; obtaining, by measurement, an SINR value of a downlink channel for performing the data transmission; determining, according to the determined CQI table or CQI table section corresponding to the data transmission mode, the resource utilization mode, or the user equipment type, and the obtained SINR value, a CQI corresponding to the SINR value; and feeding back the determined CQI to a network side entity.</p> |
