5G NR Physical Downlink Shared Channel (PDSCH) From the series: 5G Tutorial Learn about downlink data transmission in 5G New Radio (NR). Explore the Physical Downlink Shared Channel (PDSCH) processing chain which includes LDPC coding, layer mapping, how resource elements are allocated for PDSCH...
TB的计算方法(matlab代码) 下面的代码完全按照上图的公式编写,其中返回参数tbs为实际tb的大小,coded_tbs为速率匹配后tb的大小。 % Determines transport block size (TBS) based on precedure given by% 3GPP 38.214 sec. 5.1.3.2.%% Arguments:% N_sh_symb - number of symbols allocated within the slot% N...
不一定,看 matlab 代码,是K'= \lceil B'/C \rceil,这里不向上取整,也应该是可以的。 在表格 38.212 Table 5.3.2-1 的第二列,即最右边那一列中,找最小的 Z,使得K_b * Z \ge K', 这个最小的 Z ,就记为Z_c; 同时,根据Z_c所在的行,我们得到i_{LS}这个值,i_{LS}是为了在 Base Grap...
如果使用[4, TS 38.212]中的DCI格式1_1,nSCID∈{0,1}nSCID∈{0,1}在与PDSCH传输相关联的DCI中由DM-RS序列初始化字段给出;否则,nSClD=0nSClD=0。 DM-RS序列生成matlab代码实现 %M为每个l对应所需的参考信号序列r_l的长度ifstrcmp(obj.dmrsType,'type1') obj.M=6;elseifstrcmp(obj.dmrsType,'type...
该样例实现了PDSCH和下行链路共享信道(downlink shared channel, DL-SCH)。发射机模型包括PDSCH解调参考信号(demodulation reference signals, DM-RS)和PDSCH相位跟踪参考信号(phase tracking reference signals, PT-RS)。该样例同样支持集群延迟线(clustered delay line, CDL)和抽头延迟线(tapped delay line, TDL)传播...
