101, obtain the channel quality parameter value;
Particularly, obtain uplink signal-channel quality parameter value or down channel quality parameter value.
Wherein, above-mentioned channel quality parameter value can indicate (Channel Quality Indicator is called for short CQI) value, signal noise ratio (Signal to Noise Ratio is called for short SNR) value etc. can reflect the parameter value of channel quality for channel quality.
With the channel quality parameter value is that descending CQI value is given an example, and how detailed description can obtain descending CQI value.For example: UE can measure the downlink wireless channel quality, and the descending CQI value that will measure feeds back to the base station.
102, according to channel quality parameter value and the one-to-one relationship of adjusting parameter, determine the adjustment parameter corresponding with above-mentioned channel quality parameter value;
Wherein, the adjustment parameter corresponding with the channel quality parameter value is uncorrelated mutually in the described one-to-one relationship.That is to say do not have necessary relation between the adjustment parameter corresponding, adjust between the parameter independent separately with each channel quality parameter value.
Wherein, be that CQI is an example with the channel quality parameter value, above-mentioned channel quality parameter value can be as shown in table 1 with the one-to-one relationship of adjusting parameter.
Table 1 channel quality parameter value and the one-to-one relationship of adjusting parameter

| CQI＝1 | Delta?1 |
| CQI＝2 | Delta?2 |
| CQI＝3 | Delta?3 |
| CQI＝4 | Delta?4 |
| CQI＝5 | Delta?5 |
| …… | …… |
Wherein, the corresponding initial adjustment parameter of CQI value can be set to a constant, is 0 for example, is understandable that, the corresponding initial adjustment parameter of different CQI values can be identical, also can be different.

| CQI value (dB of unit) | Adjust parameter (dB of unit) |
| CQI＝1 | Delta?1 |
| CQI＝2 | Delta?2 |
| CQI＝3 | Delta?3+Deltaup2 |
| CQI＝4 | Delta?4 |
| CQI＝5 | Delta?5+Deltaup1 |
| …… | …… |
Subsequently, suppose and obtain CQI=5, can determine the adjustment parameter Delta 5+Deltaup1 corresponding according to the one-to-one relationship in the table 3 so with CQI=5.If the BLER that obtains, then will adjust parameter Delta 5+Deltaup1 less than the BLER desired value that sets in advance and adjust upward a rise parameter D eltaup3, adjustment parameter=(Delta the 5+Deltaup1)+Deltaup3 after promptly adjusting.So, utilize adjustment parameter (Delta the 5+Deltaup1)+Deltaup3 after adjusting, upgrade the adjustment parameter of CQI=5 correspondence in the described one-to-one relationship, as shown in table 4.

| CQI＝2 | Delta?2 |
| CQI＝3 | Delta?3+Deltaup2 |
| CQI＝4 | Delta?4 |
| CQI＝5 | Delta?5+Deltaup1+Deltaup3 |
| …… | …… |
