Sequence indicates the type of basic waveform included in user's waveform, carries out various permutation and combination on the basis of being based on type
Various user's waveforms can be then formed afterwards.
In this embodiment, user's waveform is a complete waveform.Such as single user may include two fields, each
Field is with 28, then equivalent storage 2*28Above user's waveform situation；If two fields of user can use a waveform table
Show, then can actually indicate 216Kind situation.
Step 103, processing is carried out to multi-user's waveform based on the channel parameter and generates simulation by real channel
Multiple user's waveforms；
In order to form simple two-way interactive and bit error rate conceptual design, user's simulator in the embodiment of the present application is also

The above-mentioned processing to user's waveform corresponds to multi-user's wave required for the embodiment of the present application for single user
The single user waveform of above-mentioned formation can then be carried out directly addition and obtained by shape.
Step 104, base station equipment is sent by the multiple user's waveform carry out multi-user test.
Process can unify to generate transmitting with postponing, based on hair as shown in figure 4, scheme provided by the embodiment of the present application
It penetrates configuration and determines the corresponding number of users of multi-user test, be then based on number of users and determine the single user waveform needed to form,
Then simultaneously for carry out inversely processing is applied alone, to obtain the multi-user's waveform formed by single user stack combinations.
The there is provided scheme of the embodiment of the present application is provided relative to traditional fixed waveform signal generator, the embodiment of the present application
Scheme original fixed waveform is carried out by Channel Processing according to testing requirement, and the multiple waveforms completed to processing are appointed
Meaning combination, forms the user information of magnanimity.To which cost of implementation is low, test method is simple, the big connection of 5G low-power consumption can satisfy
Test specification requirement.
Optionally, in order to realize the diversity of user's waveform and make the obtained user's waveform of simulation closer to by true
The waveform of real field scape, the embodiment of the present application can complete the implementation of waveform combination as follows:
In the embodiment of the present application, user's waveform can be disassembled is 4 kinds of basic waveforms constituted substantially: 1, user information
Waveform (user's waveform basis constitutes as shown in Figure 5)；2, user time stabs waveform；3, user content waveform；4, for verification
Then waveform maximizes multiplexing and combination between each waveform.
When above-mentioned 4 kinds of basic waveforms carry out random combine, the effect of multiple shot array can be formed, i.e., total number of combinations quantitative change
It is 232×232×…28Effect.
Because user information waveform can store 28Kind waveform, then user time stamp waveform also can store 28Kind waveform,
Based on 4 kinds of basic waveform situations pointed in the embodiment of the present application, then user's wave shape content can store 2~4*28Kind, school
Testing waveform is then 24, this makes it possible to the connecting methods based on user's waveform to approximately reach 232Secondary combination does not have to primary storage 210,
To reduce resource consumption.
For example, needing 2 to indicate million users20A user's Wave data, needs 20bit to indicate in practice, corresponding wave
Shape files will need 220A, this needs biggish amount of storage.
But by the way that waveform is disassembled after, it can be found that: user's packet timestamp and User ID can share waveform, therefore
It can only storage 28Kind basic user ID waveform, timestamp equally store 28Kind；And using user's packet timestamp and User ID stab into
Row combination multiplexing, such maximum can achieve 216Kind combination.If in conjunction with other multiplex modes, it is easy to reach maximum 220Kind
Combination.
In addition the method for expanding waveform combination sample is to carry out dynamic to update waveform combination, such as passing through splicing every time
After forming new user's waveform, the mode which combines is saved as a combined sample, to reach
(basic waveform is carried out according to the contoured configuration to be spliced to form the multi-purpose of multiple waveforms combination to the purpose for expanding combined sample
Family waveform).Specific implementation is as follows:
(1) by the basic waveform, sequence endless form is combined to form user's waveform respectively；
Sequence cycles through mode and chooses waveform；Such as User ID takes serial number mode, timestamp also takes sequence
Numbering.User ID waveform and timestamp waveform are selected according to number order, then selection waveform is combined and is used
Family waveform.
(2) user's waveform of new waveform combination is loaded offline；
When user's waveform is sending current 28When group user's waveform, new user's waveform can be loaded offline, and sending
After, it completes waveform and updates, to ultimately form complete random million users load.
Wherein, the specific implementation that offline waveform updates may is that
After the starting of multiuser transmission process, whether judgment frame Timing Synchronization is reached, if do not reached, continues waiting for；
If reached, judge whether all user's waveform traversals are completed, if completed, update wave file group, generates new multi-purpose
Family waveform is simultaneously sent；If traversal is not completed, generates multi-user's waveform and send.
Optionally, it is contemplated that the scene of non-orthogonal multiple, i.e., the identical running time-frequency resource scene of multiple user occupancies can will
Such case is treated according to single user, then is carried out basic waveform according to the contoured configuration being spliced to form multiple waveforms combination
Multi-user's waveform, may is that
If the identical running time-frequency resource of multiple user occupancies, generates use corresponding to each user in multiple users offline
Family waveform, and by the corresponding user's addition of waveforms of the multiple user, form non-orthogonal multi-user's waveform.It then proceedes to
Pass through the nonopiate waveform transfer of combined waveform.
Furthermore, it is possible to which the waveform of storage is revised as sets of waveforms waveform, i.e. a waveform includes multiple user's combined arrangements,
Then this user group content according to unified mode carry out frequency deviation, when partially, path loss, channel；But since the support of this equipment includes
Multiple user groups, thus practical final waveform send contain a variety of frequency deviations, when partially, multi-user's waveform of path loss, channel；From
And form larger interactive multi-user waveform.
For method provided by the embodiment of the present application according to channel conditions (transmission conditions and testing requirement) is received, selection is each
User needs the waveform combination that sends, and when adding partially, frequency deviation, path loss and channel situation, be further based on power and reception
Synchronous situation sets user's contoured configuration, the random combine of user's waveform is realized, to simulate interaction effect；To maximum
The analog signal of limit is formed by waveform by really scene, so that the obtained result of multi-user test more meets reality
Scene needs, more accurate.
Waveform is organized for the nonopiate waveform of single Waveform storage and multi-user, and participates in waveform as unified user group and closes
And more massive user's test sample is formed, so that test can satisfy more scene demands.
