Status information cannot report base station；This will also increase the burden of base station maintenance cell index, because base station
Need the channel condition for estimating which cell in advance good, so that channel condition information can be preferential in conflict
Report these cells.
Meanwhile, in acyclic information feedback, because of the Physical Uplink Shared Channel for distributing
The resource constraint of (Physical Uplink Shared Channel, PUSCH) so that user equipment can not
The channel condition information of all component carriers or part component carrier is fed back on the PUSCH for being distributed, is entered
And be likely to cause base station to do the scheduling of resource decision-making for making mistake, reduce spectral frequencies.
To solve the above-mentioned problems in the prior art, the technical scheme that the embodiment of the present invention is used passes through
The channel condition information of carrier aggregation subdistrict of the user equipment to being configured is measured, and therefrom chooses letter
The information feedback of top-quality at least one carrier aggregation subdistrict in road is to base station so that base station
Can be according to the channel status of at least one best carrier aggregation subdistrict of the channel quality of user equipment to report
