PDSCH channel

MCS index table for PDSCH (38.214 §5.1.3)


 number of symbols of the PDSCH allocation within the slot
 number of REs for DM-RS per PRB
 number of REs for overhead per PRB
 Transmission bandwidth configuration, expressed in units of resource blocks
 number of layers
 number of downlink slots per frame
 TB scaling field in the DCI 1_0 (P-RNTI, or RA-RNTI)
 Bler rate in %

Transport block size determination (38.214)

N'RE = NscRB x Nsymbsh - NDMRSPRB - NohPRB = 12 x 13 - 12 - 0 = 144
Total number of REs allocated for PDSCH NRE = min(156, N'RE) x nPRB = 39312
Ninfo = NRE x R x Qm x ν

CSI Resources for Interference

Channel State Information (CSI) processes
CSI-IM resources describe a set of Resource Elements (REs) over which the average power is measured by the UE. These measurements are used to estimate the interference for CSI calculations
