Embodiment one:

See also Fig. 1, the flow chart of a kind of uplink quality acquisition methods of providing in the embodiment of the invention is provided Fig. 1.As shown in Figure 1, this method can may further comprise the steps:

101, measure the uplink quality of user terminal, obtain the uplink quality measured value to the base station;

Wherein, measure Signal to Interference plus Noise Ratio (the Signal to Interference plus Noise Ratio that uplink quality can adopt up link, SINR) represent, that is to say, can measure uplink quality by the SINR that measures up link.Certainly, can also be by measuring the parameter that other can reflect uplink quality, for example the receiving velocity of the transmitting power of up link, up link waits and measures uplink quality.

102, judge whether above-mentioned uplink quality measured value is unusual, if then above-mentioned uplink quality measured value is corrected, to eliminate anomalous effects;

103, the uplink quality measured value after correcting is carried out smothing filtering and/or average.

Wherein, if eNB judges that the uplink quality measured value that obtains is normal in the above-mentioned step 102, then eNB can carry out normal uplink quality measured value smothing filtering and/or average in the embodiment of the invention, obtains the uplink quality of the truth of up link.

Owing to can measure up link SINR according to the uplink data sending of UE when UE sends data, if the indication that UE does not correctly receive eNB, then can not send data, this moment, eNB can not determine the indication whether UE correctly receives eNB, the up link SINR to UE measures under data or other the unusual situations thereby may not send at UE, and such measured value is inaccurate.In the embodiment of the invention one, earlier the uplink quality measured value that obtains is adjudicated, eliminate the anomalous effects of uplink quality, and then carry out smothing filtering and/or average, can obtain accurate more uplink quality, make the uplink quality that obtains more press close to the truth of up link, eliminate uplink quality unusually to the influence of the constringency performance of uplink scheduling and uplink power control.
