103rd, access device is according to the terminal ability information and access device corresponding with the terminal ability information
Attribute, the channel quality instruction to terminal measurement are adjusted correspondingly.
After access device obtains terminal ability information, with reference to access device category corresponding with the terminal ability information
Property, the reason for CQI of the terminal measurement is relatively low is determined, so as to select suitable CQI adjustment algorithms pair according to the reason for determination
The CQI of the terminal measurement carries out corresponding CQI adjustment, such as, if need to carry out quick CQI convergence algorithms to terminal.
Wherein, access device attribute corresponding with the terminal ability information does not send out CRS's for example including access device
Sub-frame formats, either whether the MBSFN sub-frame form of access device configuration or access device use new wave-carring type (New
Carrier Type, NCT), or whether access device configure almost blank subframe（Almost Blank Subframe, ABS）
The characteristic about access device itself such as sub-frame formats.
Above-mentioned access device is only with reference to terminal ability information access device attribute corresponding with the terminal ability information
Afterwards, the reason for CQI of measurement is relatively low could be judged, for example, terminal is that special measurement is not done in the case of MBSFN sub-frame

The reception machine information at end so that the double fluid of access device or the inaccuracy of multithread CQI adjustment algorithms.In the present embodiment, work as access
Equipment is obtained after terminal ability information, it may be determined that the reception machine information of the terminal, with reference to the access device attribute, selection
Suitable double fluid or multithread CQI adjustment algorithms carry out corresponding CQI adjustment.
It should be noted that quick CQI convergence algorithms and MU-BF double fluids or multithread CQI evaluation methods can be existing skills
Algorithm in art：
For example, realize the quick compensation to relatively low CQI using the CQI adjustment amounts become soon.First, access device is according to terminal
Ability information（Such as the measurement attribute of terminal）, it is assumed that it is determined that using the CQI methods of adjustment of Fast Convergent, terminal is to access device
After reporting CQI, access device is adjusted according to the UE ACK messages fed back or NACK message to CQI.For example, when terminal is fed back
During continuous N number of ACK, CQI adjustment amounts increase, corresponding CQI adjustment formula can be expressed as：Adjustment amount=0.1* (desired value-survey
Value) * N/ (1- desired values）.Wherein, N represents the statistics continuous numbers of ACK, and desired value and measured value refer to initial bLock error rate
IBLER desired value and measured value, it is assumed that desired value can be 10%, when terminal feeding back ACK message, measured value 0, when anti-
When presenting NACK message, measured value 1.
It should be noted that the CQI provided in the present embodiment quickly adjusts formula, it is not that unique adjustment amount calculates
Formula, the fast adjustment method that any ACK message quantity with continuous feedback increases and causes CQI adjustment amounts to increase are included in
It is interior.
In another example the quick compensation to relatively low CQI is realized by the method for forward direction compensation.First, access device is according to end
Hold ability information（Such as the measurement attribute of terminal）, it is assumed that it is determined that using the CQI methods of adjustment of Fast Convergent, terminal is set to access
After CQI is reported, the CQI that access device reports terminal carries out positive compensation, then utilizes traditional CQI methods of adjustment to carry out
CQI is adjusted.Wherein, traditional CQI methods of adjustment are that CQI is adjusted according to the ACK message or NACK message of terminal feedback,
Corresponding CQI adjustment formula can be expressed as：Adjustment amount=0.1* (desired value-measured value)/(1- desired values）.Wherein, desired value
Refer to initial bLock error rate IBLER desired value and measured value with measured value, it is assumed that desired value can be 10%, when terminal is fed back
During ACK message, measured value 0, when feeding back NACK message, measured value 1.
The embodiment of the present invention, when access device receives the channel quality indication (CQI) information of terminal transmission, the channel matter
Amount instruction information includes the mark of the terminal and the channel quality instruction of terminal measurement；Access device is according to the end
The mark at end, inquire about terminal ability information list, obtain corresponding with the mark of terminal terminal ability information, and with institute
Access device attribute corresponding to terminal ability information is stated, it is right according to the terminal ability information and the access device attribute
The channel quality instruction of the terminal measurement is adjusted correspondingly；Access device is not needed to iterate through a period of time self study
Terminal ability information is obtained, saves the time that access device obtains terminal ability information, access device selection CQI is accelerated and adjusts
The time of adjusting method, it is thus possible to improve CQI regulated efficiencies.
