Number obtain in 50 data transmission procedures and just to pass the successful number of data and again for example, Preset Transfer number is 50 times
The successful number of data is passed, later, the successful number of data and the re-transmission successful number of data is passed according to first, determines NPUSCH's
The bit error rate.
Wherein it is possible to according to scheduling information DCI0 (Downlink Control Information, the downlink control of NPUSCH
Information processed) in NDI (New Data Indication, new data instruction) determine data whether transmission success, if NDI is overturn,
Then indicate that current NPUSCH is just to pass, i.e., last data transmission success, if NDI is not overturn, then it represents that current NPUSCH attaches most importance to
It passes, i.e., last data transmission fails.For example, NDI when can be transmitted by second of data determines that first time data are transmitted
Whether succeed, if NDI is overturn, then it represents that first time data transmission success, if NDI is not overturn, then it represents that the transmission of first time data
Failure；Further, if second of data is transmitted as retransmitting, NDI when can be transmitted by third time data determines second
The data of secondary re-transmission whether transmission success, if NDI is overturn, then it represents that the second data transmission success retransmitted, if NDI is not turned over
Turn, then it represents that second of data transmission fails retransmitted.Thus, it is possible to obtain in data transmission procedure, just biography data are successfully secondary
Number and the re-transmission successful number of data.
Illustratively, the bit error rate can be obtained by following formula (1):
BLER=M/ (N+M) (1)
Wherein, BLER (Block Error Ratio, the bit error rate) is the bit error rate, and M is to retransmit the successful number of data, and N is

Wherein it is possible to which default adjustment amplitude is arranged in the requirement according to UE to performance, for example, default adjustment amplitude can be set
For 1dBm.
In this step, when the bit error rate is outside default bit error rate range, if the bit error rate is more than or equal to default error code
The upper limit of rate, then it represents that NPUSCH channel it is second-rate, can according to default adjustment amplitude improve NPUSCH transmission power,
So as to improve the quality of NPUSCH channel, improve the performance of UE；If the bit error rate is less than or equal under the default bit error rate
Limit, then it represents that the quality of NPUSCH channel is preferable, and the transmission power of NPUSCH can be reduced according to default adjustment width, so as to
