It is appreciated that in actual applications, user equipment is a fixed response time be present to reporting for CQI, for example CQI is from survey
Measure report when extend to the time delay for reporting the time to scheduling instance, then the CQI of user equipment to report and actual channel situation be also
Certain error be present.Base station just needs to be adjusted the CQI of user equipment to report, specifically can be by outer loop link certainly
Adapt to（Outer Loop Link Adaptation, OLLA）Method the CQI reported is compensated, mainly utilize user
Equipment instructs downlink transfer correctness CQI adjustment, and user equipment can be to base when being properly received downlink transfer
Feedback of standing affirmative acknowledgement（Acknowledgement, ACK）Information, can be to base station feedback when not being properly received downlink transfer
Negative response（Negative Acknowledgement, NACK）Information.Then specifically：
Base station can set CQI compensation rate ΔOL, when base station receives the ACK of user equipment feedback, illustrate actual
Channel quality is preferable, then CQI reports value too cautious, it is necessary to lift CQI, then in the compensation rate ΔOLOn the basis of add one
Raise step deltaup；When base station receives the NACK of user equipment feedback, illustrate actual channel quality decline, then CQI is reported
Value can be higher, it is necessary to reduce CQI, then in the compensation rate ΔOLOn the basis of subtract one downward step deltadown, so dynamically
CQI compensation rate is adjusted, can finally make the bLock error rate of downlink transfer（Block Error Ratio, BLER）Converge to target
It is worth, in the present embodiment, when ability signal interference state changes, accordingly by lifting up-regulation step-length or step-length can be lowered,
BLER is restrained rapidly, compensate for the influence to caused by channel quality during signal interference state change.In general, raise
Step deltaup, lower step deltadownRelation between BLER desired value is：Wherein,
BLERtargIt is BLER desired value.
If the CQI of the user equipment to report is CQIrep, then the effective CQI finally given is：After the CQI reported and adjustment
Compensation rate sum, i.e. CQIeff=CQIrep+ΔOL。
It can be seen that in the embodiment of the present invention, base station can be according to the shared resource in the first communication system and the second communication system

The CQI reported can reflect the information of actual signal quality, then base station is only in the first communication system signal by other system signals
During interference, the CQI of user equipment to report is compensated.Again because the CQI of user equipment to report is the SINR according to each subband
Measured value merges obtained average SINR mappings, will exclusively enjoy the SINR of each subband in resource and shared resource
Averagely obtained, if wherein in shared resource, if a communication system signal is believed another communication system
Number disturbed, then the SINR obtained can be relatively low, such that the SINR integrally obtained average value（That is CQI）It is relatively low, then
Need to compensate the CQI of user equipment to report, the quality information of actual channel could be reflected；And due to exclusively enjoying resource and being total to
The channel quality difference in resource is enjoyed, it is necessary to be compensated with different compensation rates to CQI.
It should be noted that illustrate to hold when state change information is the first change information in above-mentioned steps 202 and 203
Capable step, when state change information is the first change information（It is undisturbed state i.e. from state transition is disturbed）, base station
The CQI of user equipment to report can need not be compensated, the tune in down frequency spectrum resources is directly instructed according to the CQI reported
