Embodiment 1
[0052] In this example, if figure 1 As shown, a self-decoding identification method applied to redundancy version number 2 in 5G base station communication, including:
[0053] Step 1: Set codec parameters, and calculate the available information length N according to the set codec parameters info ;
[0054]Step 2: Calculate the information length N according to the preset conditions info The basegraph is used to judge, if the preset conditions are met, it is judged that the redundant version number cannot be solved by itself, otherwise the redundant version number can be solved by itself.
[0055] In this embodiment, step 1 specifically includes setting R as the target code rate, and Q m is the modulation order, and v is the number of layers. N info is the available message length, calculated as follows:
[0056] N info =N RE *R*Q m *v
[0057] N RE is the number of available Re (resource particles), the calculation formula is as follows:
[0058] N RE =min(156,...
Embodiment 2
[0083] In this embodiment, the simulation parameter simulation is performed on the basis of the method provided in the first embodiment. Among them, the scheduling physical layer parameters are shown in Table 2 below:
[0084] Table 2 Simulation parameters and results table
[0085]
[0086] The first column of the table is the order of the cases. The second column is the number of scheduled RBs (resource blocks). The third column is the table of the MSC used by the dispatch and the index in the table of the MSC. R is the code rate. BG is selected for LDPCbasegraph. TBS is the block length of the transmission. CRC is the final demodulation result, CRC=0 means demodulation is correct, CRC=1 means demodulation error.
[0087] N of Case 1 info >8424, Rinfo / R / C=24027>2.5*(8448+24)=21180, CRC=0, the demodulation is successful, which meets the conclusion of 3.2; similarly, case 2 also meets the conclusion of 3.2.
[0088] N of Case 3 info >8424, R>0.25, N info / R / C=120...
Embodiment 3
[0093] In this embodiment, the specific steps and procedures of the relevant parameter calculation methods involved in the above-mentioned embodiments 1 and 2 are given, specifically including:
[0094] 1. According to the 3GPP38.214 protocol, the calculation method of the number of code blocks C is as follows:
[0095] If N info ≤3824, then C=1;
[0096] If N info >3824 code rate is less than 1 / 4, then
[0097] If N info >3824, and the code rate R is greater than 1 / 4, but N info ′>8424, then
[0098] If N info >3824, and the code rate R is greater than 1 / 4, but N info '≤8424, then C=1.
[0099] where N' info is calculated as:
[0100] When N info ≤3824, there are:
[0101] in
[0102] When N info >3824, there are:
[0103] in
[0104] 2. The calculation method of the transport block size (TBS: Transportblocksize) in this embodiment is as follows:
[0105] If N info <=3824
[0106]
[0107]
[0108] TBS is equal to greater than N' in Table ...
