The initial transmission rate PinitialThe initial value for referring to carrying out testing throughput, when testing every time mobile terminal 105,
Base station simulator 101 always since one most relatively low transmission rate, gradually increase transmission rate, until accidentally
Block rate is exceeded.
S5: the correct frame number that measurement LTE-TDD mobile terminal 105 receives is M, and calculates this according to expression formula (1)
When block error rate BLER:
S6: if LTE-TDD mobile terminal Block Error Rate does not have exceeded (it is not exceeded for defining BLER less than 1%), test
101 transmission rate of system control base station simulator increases a predetermined value.
S7: if Block Error Rate do not have it is exceeded, repeat step S5 to S7 until bit error rate BLER it is exceeded.Record base station mould at this time
The transmission rate R of quasi- device 101testAnd block error rate BLER.
S8: the goodput T of LTE-TDD mobile terminal is calculated according to expression formula (2)test。
Ttest=Rtest×(1-BLER) (2)
Wherein, test indicates the MIMO OTA testing throughput actually carried out, RtestWhen indicating closest critical Block Error Rate
The transmission rate of base station simulator 101, BLER indicate corresponding Block Error Rate, TtestIndicate the reality of the multiple antennas mobile terminal measured
Border handling capacity, unit are megabits per second (Mbps).
In the test process of above-mentioned typical LTE-TDD mobile terminal handling capacity, due to the duration of step S5 needs
Be it is fixed, the number that step S5 is repeated is more, and total testing time will be longer.The algorithm of existing typical case's test process
