TB Size(transport block size) defines how many bits MAC layer transfers to Physical layer per TTI (Transmission Time Interval, defined as 1ms). Note: TM1/TM2 can carry 1 TB Size per TTI, TM3/TM4 can carry 2 TB Size per TTI (two code word).

LTE Quick Reference Go Back To Index Home : www.sharetechnote.com. Code Rate. Simply put, the code rate can be defined as the ratio of the data rate that is allocated for a subframe and the maximum data rate that ideally can be allocated in the subframe .

After the device’s radio context has been restablished, the cellular tower notifies the MME, which in turn notifies the S-GW, which is now able to route the message to the correct radio tower. Finally, the tower sends the data to the device through the device’s LTE modem interface .
Read moreWhat is rate matching in 5G?
The rate-matching is to extract the exact set of bits to be transmitted within a given TTI . The rate-matching for Turbo coded transport channels is defined for each code block: there are three basic steps composing a rate-matching. Namely, sub-block interleaver, bit collection, and bit selection.
Read moreWhat is transport block LTE?
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
Read moreWhat is code word in 5G?
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.
