A method for adjusting a channel quality indicator feedback cycle, comprising: receiving a channel quality indicator, CQI, adjustment parameter reported by a base station, and determining, according to the CQI adjustment parameter, whether a CQI feedback cycle of a user equipment needs to be adjusted; and when it is determined that the CQI feedback cycle needs to be adjusted, adjusting the CQI feedback cycle of the user equipment, and sending an adjusted CQI feedback cycle to the user equipment, characterized in that the CQI adjustment parameter is a value of transmit power used by the user equipment reported by the base station; and the determining, according to the CQI adjustment parameter, whether the CQI feedback cycle of the user equipment needs to be adjusted is: determining whether the value of transmit power used by the user equipment reported by the base station is greater than a first power threshold value, or is smaller than a second power threshold value; and the adjusting the CQI feedback cycle of the user equipment is increasing the CQI feedback cycle of the user equipment when the value of transmit power used by the user equipment is greater than the first power threshold value; or the adjusting the CQI feedback cycle of the user equipment is decreasing the CQI feedback cycle of the user equipment when the value of transmit power used by the user equipment is smaller than the second power threshold value; wherein the first power threshold value is greater than the second power threshold value. receiving a channel quality indicator, CQI, adjustment parameter reported by a base station, and determining, according to the CQI adjustment parameter, whether a CQI feedback cycle of a user equipment needs to be adjusted; and when it is determined that the CQI feedback cycle needs to be adjusted, adjusting the CQI feedback cycle of the user equipment, and sending an adjusted CQI feedback cycle to the user equipment, characterized in that the CQI adjustment parameter is a value of transmit power used by the user equipment reported by the base station; and the determining, according to the CQI adjustment parameter, whether the CQI feedback cycle of the user equipment needs to be adjusted is: determining whether the value of transmit power used by the user equipment reported by the base station is greater than a first power threshold value, or is smaller than a second power threshold value; and the adjusting the CQI feedback cycle of the user equipment is increasing the CQI feedback cycle of the user equipment when the value of transmit power used by the user equipment is greater than the first power threshold value; or the adjusting the CQI feedback cycle of the user equipment is decreasing the CQI feedback cycle of the user equipment when the value of transmit power used by the user equipment is smaller than the second power threshold value; wherein the first power threshold value is greater than the second power threshold value. determining whether the value of transmit power used by the user equipment reported by the base station is greater than a first power threshold value, or is smaller than a second power threshold value; and the adjusting the CQI feedback cycle of the user equipment is increasing the CQI feedback cycle of the user equipment when the value of transmit power used by the user equipment is greater than the first power threshold value; or the adjusting the CQI feedback cycle of the user equipment is decreasing the CQI feedback cycle of the user equipment when the value of transmit power used by the user equipment is smaller than the second power threshold value; wherein the first power threshold value is greater than the second power threshold value.
