The calculation of LTE code rate is done based on MCS, PRBs and OFDM symbols per slot . The LTE code rate calculator outputs code rate. It takes into account percent of REs used in control channel operation. The PRBs stands for Physical Resource Blocks allocated to the UE by eNB.
Read moreWhat are transport blocks?
Transport Block is a packet of data which is passed between the MAC and Physical layers . It is passed downwards at the transmitter and upwards at the receiver. A Transport Block undergoes Physical layer processing at the transmitter before being mapped onto the PDSCH for transfer across the air-interface.
Read moreHow is TB size calculated?
Step to Calculated TBS The total number of REs within the bandwidth of a single RB is 12 x 14 = 168 using normal cyclic prefix . The final value is multiplied by the number of allocated Resource Blocks to generate a value for .16 Ağu 2020
Read moreDoes LTE support 256 QAM?
One of the LTE features introduced in Rel-12 is the support for higher order modulation, that is 256QAM for DL data transmission to enhance the spectral efficiency and the system throughput.
Read moreWhich 3GPP release supports 256 QAM in the downlink?
From Rel 12 , 3GPP defines (support) 256 QAM in Downlink.
Read moreWhat QAM 256?
Just what is QAM-256? It refers to Quadrature Amplitude Modulation , which is the means by which a carrier signal, such as an LTE waveform, transmits data and information. Ideally, a waveform/symbol carries as much data as possible in order to achieve higher data rates and increase spectral efficiency.
Read moreHow do you calculate QAM?
The required bandwidth is related to bit rate and the modulation order M. It is so that the double sided bandwidth w = symbol rate= bit rate rb/ divided by the number of bit per symbol n . The number of bits per symbol is = log 2M with M is the M is the QAM modulation order.
