Channel quality . Radio conditions impact user bit rates. The better radio conditions the higher throughput is available and vice versa. eNB (eNodeB, base station) selects Modulation and Coding Scheme (MCS) based on current radio conditions. The higher MCS the more bits can be transmitted per time unit.

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.
Read moreWhat is CRC attachment?
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.
Read moreHow is LTE throughput calculated?
If modulation used is 64 QAM (6 bits per symbol) then throughput will be 16.8×6=100.8Mbps for a single antenna port . If we consider a 2×2 MIMO system then this throughput will be double i.e. 100.8×2= 201.6 Mbps and with 4×4 MIMO system then throughput is about 100.8×4= 403.2 Mbps.
Read moreHow is resource block calculated in LTE?
According to LTE specifications, for 10 MHz bandwidth channels, the number of resource blocks= 50, each resource block is assigned 12 sub carriers for the duration of 0.5 seconds of 6-7 ofdm symbols. The number of bits in one resource block= 12x7x no.
Read moreHow can we calculate LTE DL UL throughput?
3 Modulation supported- as per Cat 3 TBS index 26 for DL (75376 for 100RBs) and 21 for UL (51024 for 100 RBs) So the throughput can be calculated by a simple formula: Throughput = Number of Chains x TB size So DL throughput = 2 x 75376 =150.752 Mbps UL throughput = 1 x51024 =51.024 Mbps As we have 2 receive chains and …
