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 transmission, and the different types of...
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...
该参考仿真展示了如何去测量3GPP NR标准定义的5G新无线链路的物理下行链路共享信道吞吐量。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...
