Transport block: Higher layer data packets are multiplexed onto transport blocks which are delivered to LTE physical layer for transmission . Per LTE transmission time interval of 1 ms, one transport block (or up to two in the case of MIMO spatial multiplexing) can be transmitted.
Read moreWhat is a transport block in 5G?
Transport Block in 5G NR, is nothing but the payload which is passed between the MAC and Phy Layers, specifically for the shared data channel such as PDSCH and PUSCH . A Transport Block undergoes Phy layer processing at the transmitter before being mapped onto the PDSCH for transmission over the air interface.16 Ağu 2020

The output of a coding chain is a codeword. 5G supports transmission of up to 8 layers to a single user on the downlink. This means that there can be up to eight streams transmitted in parallel.
Read moreWhat is code block in LTE?
for code block segmentation used on LTE-Advanced channel coding physical layer (PHY) is presented in this paper. Code block segmentation is a generic procedure which is commonly applied before turbo encoding . Its main function is to fragment a large transport block into smaller code blocks.

Transport Block CRC Attachment A cyclic redundancy check (CRC) is used for error detection in transport blocks . The entire transport block is used to calculate the CRC parity bits. The transport block is divided by a cyclic generator polynomial, described as g C R C 24 A in section 5.1.

Abstract: In LTE (Long Term Evolution) systems, the PRB (Physical Resource Block ) usage ratio is considered importantly to manage the QoS (Quality of Service) of LTE traffic. As the PRB usage ratio increases, the resource may not be allocated in a timely and reliable manner to the users of the cell.
Read moreHow does LTE calculate PRB?
Physical Resource Block (PRB) = 2*Resource Block = 12 Subcarriers x 14 OFDM in 1ms . RE can deliver 2, 4, 6, 8 bits in QPSK, 16QAM, 64QAM, 256QAM respectively. If we calculate for 64QAM as 6bits since 256QAM not widely spread (check Samsung S7 in T-Mobile). 20MHz ==> 100 PRB ==> 100*168*1000 = 16,800,000 RE in 1 s.
