Embodiment
The embodiment of the present invention provides a kind of terminal traffic channel test method and comprehensive test instrument, in comprehensive test instrument according to receiving
The corresponding data of the pilot frequency locations of two time slots in subframe, two row in each subframe that may be sent with transmitting terminal respectively are with reference to symbol
Number related, the subframe numbers for the subframe for determining to receive according to correlated results are carried out, and then terminal traffic is carried out according to the subframe numbers
Channel test, due to reporting subframe numbers without terminal, so improving test flexibility, improves testing efficiency.
As shown in Figure 1, terminal traffic channel test method provided in an embodiment of the present invention, including：
Step S101, in the subframe received, the corresponding data of pilot frequency locations of each time slot are intercepted；
Step S102, each son that may send the data that the pilot frequency locations of time slot 0, time slot 1 receive with transmitting terminal respectively
The time slot 0 of frame, the reference symbol of time slot 1 carry out correlation, determine peak position, and according to peak position, determine the son received
The subframe numbers of frame；
Step S103, terminal traffic channel test is carried out according to the subframe numbers of the subframe received.
Since in step s 102, the data received according to the pilot frequency locations of time slot 0, time slot 1 respectively may with transmitting terminal
The correlated results of the time slot 0 of each subframe sent, the reference symbol of time slot 1, it is determined that the subframe numbers of the subframe received, without
Subframe numbers are sent by terminal, reduces the interaction between comprehensive test instrument and terminal, improves testing efficiency.
To the definite process of subframe numbers, realized when main using the difference between two time-multiplexed pilots in different subframes
's.Specifically, can utilize receive subframe in two pilot frequency locations data, with two pilot tones in each subframe respectively into
Row is related, obtains the corresponding position of peak value respectively, if identical with the peak position of certain two pilot tone of subframe respectively, illustrates to receive number
According to two pilot tones to the pilot tone of the subframe numbers be at utmost similar, you can it is that terminal sends out data to determine the subframe numbers
Position.
By taking terminal sends subframe 3 as an example, correlation curve is as shown in Fig. 2, time slot 0, the pilot frequency locations number of time slot 1 of the subframe
