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 affects LTE throughput?
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.
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 …
Read moreWhat is TB in LTE?
Transport Block & Code Block The TB is nothing but a group of bits of length as per the LTE standard . The range of TB is 16 to 36696 bits for a 10MHz LTE system. The TB is divided into code blocks or CB, if the size of the TB is greater than or equal to 6144 bits.
Read moreWhy are different modulation and coding schemes used?
The different EDGE modulation coding schemes are used as required to provide the optimum balance between high data rate and low error rate . As signal levels fall and noise levels rise, the higher levels of error correction are needed to maintain the integrity of the link.
