Embodiment 3
The present embodiment is that according to an alternative embodiment of the invention, the application is carried out specifically for combining concrete scene
It is bright：
The present embodiment is 3.75k subcarrier automated wireless indication test methods under NB_IOT standards.This method utilizes filling
Enter the upward signal of signal source NB-IOT standards, received by base station to complete wireless index test.Due to general signal source
Can only support with network side 10ms clock alignments, can not directly carry out the 3.75k of up NB-PUSCH channels under NB_IOT standards
The single RU of subcarrier is the index test of 32ms periodic signals, and same directly can not also repeat to NB-PRACH signals, single
For the index test of 5.6ms periodic signals.The present invention, which proposes a kind of method, can complete up NB- under NB_IOT standards
The automated wireless index test of PUSCH channels and NB-PRACH channels.
The present embodiment includes：
The first step by the method in replica signal source, it is necessary to produce the signal of 10ms cycle integral multiples, for 3.75k's
NB-PUSCH channels, each RU are 32ms signal, then need to produce (RU* number of repetition * 5*32) ms signals, such as：For 1
The 32ms signals of individual 1 repetition of RU are, it is necessary to signals by replicating 5 generation 160ms, for 10 RU, 128 repetitions
40960ms signals are, it is necessary to by replicating 5 signals for producing 204800ms.For RRACH channels, constructed according to number of repetition
After completing data source, by mending 0 method polishing below to 10ms integral multiple, as shown in table 1：
Table 1
Second step, 10ms detector will be added caused by the first step before source signal, this 10ms detector contains spy
The ZC sequence signals of different scrambler, by constantly detecting in 10ms, whether the ZC sequence signals containing special scrambler are found network side
Signal source sends the original position of data, and then the original position alignment sent with signal source.
3rd step, base station side are found after the original position of signal source transmission, it is possible to according to the transmission cycle of source data
Normal Channel Processing is done with number of repetition, completes wireless index test.
Whole wireless index test process need not be participated in manually, and the signal source of generation ensures 10ms length integers times and added
Upper 10ms head, network side send original position with signal source and alignd using searching algorithm and be automatically performed.
The wireless index that the method for the present embodiment can be carried out under NB_IOT standards using signal source is tested, and whole nothing
Line index test process need not be participated in manually, and search and signal source send signal alignment to network side automatically.
The present embodiment focuses on：It is whole by the method generation 10ms cycles in replica signal source for NB-PUSCH channels
The signal of several times, the signal that each RU for 3.75k is 32ms, RU*5*32ms signals are produced, such as：For 1 RU 1 time
The 32ms signals repeated, 5 generation 160ms data source signal is replicated, for 10 RU, the 40960ms of 128 repetitions believes
Number, replicate 5 data source signals for producing 204800ms.
For NB-PRACH channels, after number of repetition construction complete data source, arrived by the method polishing for mending 0 below
10ms integral multiple.
10ms detector will be added before data source signal, this 10ms detector contains the ZC sequences letter of special scrambler
Number.
Network side constantly detects in 10ms whether the ZC sequence signals containing special scrambler send data to find signal source
Original position, and then with signal source send original position alignment.
The present embodiment also includes two instantiations：
