6-force method method T-C A physical channel format

7 force this method another way of the process.

The preferred way of this

The following break mode is combined with this step.

The T SC A test-like generating device, the rest mode, 1 includes BB (ga Base-B d ) generation and BB is generated in the generated BB test, and the same information included in each interaction with the terminal is The test will be similar to the test.

In the way, BB generates the available software method, which fully expands the software to generate the proportion of the system. The ability to use the software is like the physical function of the gods, and the households meet the T-C A BB. The hardware can be compared with the general-purpose front-end RF hardware that is generated by the BB, and the T-C A terminal is tested.

In the mode, the BB generates the generated T-C A-compliant BB, which can be regarded as a software-like T-C A physical system, and the downstream functions of each downlink and terminal. It can be 3 PP (d-Ge e o e s p Oec third-generation partner) R8 version of the total and each, PA A and each household function. For the CCTC (CodedCompos eT spo Cha e), the routine and the responsibility, complete the forward,

Columns for combination, rate matching, , , and physical mapping. Can Similar information in the interaction with the terminal, including information, TFC (Ta sm Foma Comb ed dcao format combination indication), (Sy cho za o Sg a synchronization) and TPC (Ta smsso owe Co o, power control) . In addition to the updated PA and A, the implementation of the track and physical functions, near perfect AC (dap ve od oa dCod g), Q (yb o Repea Req es hybrid) and 16QA4 (6 Q ada e Amp de Od o 16 amplitude) high, household and interactive controls, roads and directions to Taoism. In addition to generating ideals, there may be more than (or more) dry resistance, more (or more) dry resistance, and a typical non-ideal shadow of the gods.

In the way, including A B (A aogBase-B d

(adofeq e cy RF) sheep, connected to BB generation and A B/R sheep in the same sheep (teaching) and FPGA control sheep, 2 shown. The FPGA controls the A B/R sheep, including the sum and power of the specified A B . BB generation in a fixed format

, do each, under the control of the FPGA control sheep A B

Fixed magnification. Receive BB generated BB test, special A B test, RF-like test at specified and power. T-C AA like test

Similarly, you can directly test and connect each connection.

In another way of this device, 3, the BB generation includes multiple ideal BB-generated sheep, which generate ideal BB to multi-small wells, phase and phase power, to seem like fading and then to.

In the above mode, all the physical reasons before the test filter are completed. BB generation software is completed, hardware

Supports all regular, S PA SA and MS of 3GPPR8 and generates and tests each of the controls, tracks and indications It seems that the interaction with the terminal, the same household and control information support small, multi-and the configuration of each friend's typical ideals are generated by BB, no additional hardware is required.

This T SC A test-like generation method, in the manner shown in 4, includes

Step 402 generates a BB test, and the BB test includes the same information in each interaction with the terminal. Step 404 BB tests the special B test.

The idea of this law is firstly configured according to the order of "small and different", and then according to the generation process of the same order.

The way this method works, is shown in build 5.

The method of this method, and the different principles and configuration methods

In the 3GPP, T-C A is in the same order and uses physical features. The existing T-C A-supported test scores are larger and each, N PA and A. Daxie can be divided into 11 small CCTC (oded Compos e Ta spo Chae) C (ag g dcao Cha e indication) FPAC (as hysca Access Cha e quick instruction), C dcao Cha e multi-media Indication) C ( ghSpeed hysca ow ShaedCha e high physical downlink sharing), CC (Sh ed Co o Cha e CC shared control), C (Sh eao Cha e CC shared information) EP C (C hysca p Cha e enhanced physical uplink ER CC (C Ra domAccess p Co o Cha e C connected to the uplink control) EAGC (C Abso eGa Cha e, EC yb dA QAck owedgeme dcao Cha e, EC mixed counter indication).

And most of the BBs are; before 3GPP R6, the CCTCs are combined in the form of a combination of them, they are mapped and common Physical (including PC CCPC SCCPC C and PC) and each physical includes TC (spo Cha e ), TF (T spo Fo a format) and PC (hysca Cha e physics). The TC (original information, size, 5 CRC bit length, mode, rate matching) is not in its TT (smsso Tme e Va, ms 2 ms 4 ms or 8 ms)

. The physical ( , , and factor) used may be TF. Partial and specific, to CCTC TT (the largest TT in CCTC TC) basic sheep configuration, including the physical allocation of each 0 TC, TF set, and maximum combination. On the other hand, there may be additional information on the physical path of the CCTC mapping, including TFC (s Fo Comb ed do format combination indication) indicating TF, TPC (smsso owe Co o power control) and synchronization (Sy co za) o S a sync). The information is the same as this mode 5 is configured in the sub (5 ms) period, in the meson,

Other physical configurations caused.

In addition, some of them are not the same as CCTC, including PC and FPAC, because they are the routines of 3 PPR6 and they are necessary, and in each mode, they are configured and used.

PA and A are T-C AA wood at 3 PP R6.

And each includes and each TC and instruction C. The TC is also in CCTC, and its configuration method and the above-mentioned conventional and phase C configuration are similar to those of the PCs in the respective settings.

The PA includes the reverse C of the stationer's high-speed downlink and each C, control CC and terminal. In the mode, the configuration method of Dange complies with the interaction defined by T-C AA. C uses the physical path and configuration of the CC and the content configuration of the CC. Then C reverses the information, combined with the AC and Q wood requirements for the household.

In the mode, the A configuration method is similar to that of the PA, and it is also the Dange-like interaction of the EP C AGC for the high-speed uplink physical configuration phase and the EC and the accompanying control CC, and the C receiving the reverse terminal R The CC is only configured in the initial connection.

In the way, T-C A physics, as shown in 6, includes the system, the sub, and /, where the 5ms long sub is the smallest sheep of each 矣 and each configured. In this way, the letter generation process is different in the same order, and each generation is generated in the TT, and each is extracted according to each other, and the complete sub-integration is integrated.

In the manner, 7 shows that the test household life includes step 702, according to the previous method, all existing and physical configurations of each line

Step 704 configuration, and each of the same and the length of the sheep (ie TT), forming a sheet and configuring each

Step 706, the same configuration table condition of each meson (5 ms)

If the step 708 is new and each is, then the special step 710, otherwise the special step 706, step 710, whether it is a special step 722, otherwise the special step 712 step 712 is in the middle of the meson or the new one, the amount Points, and the generation of each BB. ,

Step 714 each phase (including typical original information, CRC, framing, rate matching, and the like), and generate physical mappings within each TT

Step 716, in the same as above, all of them, and each of the former sub-extracts, and mdambe distribution. Special (wPT or upstream pPT) is also in the sub-position

Step 718 is completed by each and each special

Step 720 is up and filtered to form a final test special step 710, forward and down meson and each configuration, until the generated sub-satisfaction is satisfied

Step 722.

The generation of the base is similar to the usual hardware approach, the configuration of the event table, and the update. Each time the sub-scores are generated, they are all configured with the necessary updates. For the CCTC, the format of each TC may be the same as the format combination indication (FC).

Updating the TFC in the TC's TT can be like a force. Similarly, the same TPC command and synchronization command can also be configured differently at the start of the meson. In PA and A, each configuration is controlled by the interaction of each other, control channel and anti-existence. The above method can also be like the interaction of the power of the gods, and the configuration of the solution is reversed, and then the configuration control is performed. The most control content determines the next configuration.

There are receiving and resolving in the interaction, you can use existing software or hardware.

In the way, there are many small and multiple situations in the communication, which can be generated separately for each small and small, respectively, the small ideal BB of each household, the smallest power difference between the smallest phase, and the different small sums, forming the final Letter. And each small existence and each, you can always put them together

However, the generation of the phase power is occupied.

In the way, the generated ones can contain non-ideal shadows. In small generation, can it

The letter of the Tao. It has a built-in sheep of the typical yuan specified on 3 PP To, multi-pass and power calibration models, including sheep's high, CA CA 2 CA 3 A3 B3 VA30 VA 20, etc., cover T-CA typical test of each god. The ideal BB is in the model, which can receive the letter.

The radio frequency of the specified power will be specified (or not), and the test will be performed. Some of them can be used commercially.

With good RF performance, you can add sheep, but most of them are very expensive and have limited functions. In this method, because the non-ideal factor test can be software, the hardware part is relatively low.

The above is a detailed description of the steps taken in conjunction with Hugh, and the rest can not be limited to the description. Ordinary Mudong in the field of this wood said that under the premise of this, some sheep can be made or replaced, and all of them are based on this guarantee.

Usability

Compared with the existing wood, it is possible to test the working condition of the terminal in a non-ideal state, improve the coverage of the test, and greatly test and reduce the cost.
