Embodiments of the present invention relate to a method, a base station and user equipment for transmitting channel quality information. The method includes: when channel quality information of Y downlink carriers is needed to be fed back by a user equipment to a base station through X uplink carriers, allocating, by the base station, resource blocks to the user equipment according to the number of bits of the channel quality information and a set of resource block numbers that corresponds to a configuration X/Y, in which X and Y are positive integers greater than or equal to 1; and configuring, by the base station, the number of the allocated resource blocks in a control signaling for uplink scheduling UL-grant, and sending, by base station, the signaling to the user equipment. It can be seen that, the base station can allocate the resource blocks to the user equipment according to the number of the bits of the channel quality information and the set of resource block numbers. As a result, uplink scheduling bandwidth can be adaptively allocated for the transmission of the channel quality information. In addition, the drawback that the transmission performance cannot be guaranteed due to the fixed bandwidth resources through which the user equipment transmits the channel quality information can be resolved. |
