A method and equipment for determining the transmission resource of channel quality indicator are disclosed. They are applied in Time Division Duplex TDD system and Half Duplex-Frequency Division Duplex HD-FDD system when Discontinuous Reception DRX operation is adopted. The method includes the following steps: determining the location of the downlink subframe where the start point of monitoring Physical Downlink Control Channel PDCCH in DRX cycle is located; determining whether the transmission resource used for transmitting the Channel Quality Indicator CQI is an uplink subframe previous to the determined location or one or more uplink subframes after the determined location. Availability of the CQI information when performing downlink schedule is guaranteed, and the transmission resource used for transmitting CQI can be effectively saved.
