Next calculate number of information bits N_info, here R is coding rate, Qm is modulation order and v is Jul 1, 2023 · The basic scheduling unit is the physical resource block (PRB), which is defined as 12 consecutive subcarriers of the same spacing in the frequency domain, i. Following the reconfiguration command, there is an acknowledgment step labeled "RRC Connection Reconfiguration Complete" in LTE and "RRC Reconfiguration Complete" in 5G, indicating that the reconfiguration process has been acknowledged by the UE. 213 communication standards and allows you to calculate 4G LTE RS Power (RSRP power) from Total RRU/RRH Power and back Total RRU/RRH Power from RS Power (PSRP power). Corresponds to L1 parameter 'PRB_bundling' The term PRB (Physical Resource Block) exists in both 4G LTE (Long Term Evolution) and 5G NR (New Radio) air interfaces. You can use SLIV value as a key value to find out a unique pair of (S, L) in a look-up table. , physical resource blocks (PRBs), transmit power) for remote radio heads (RRHs) in the fifth generation (5G) cloud radio access network (C-RAN) is crucial for the mobile network operators (MNOs) to support different use cases with diverse quality of service (QoS) requirements. Step 1: Bits per PRB Calculation: Number of subcarriers per PRB: 12; Symbols per sub-frame: 7 (assuming normal CP) Bits per RE (Resource Element) for 16QAM modulation: 4; Bits per PRB: 12 subcarriers × 7 symbols × 4 bits/RE = 336 bits (per 0.
