WebDec 17, 2024 · An Adaptive Rank Selection Method in 3GPP 5G NR Systems Abstract: A user equipment (UE) estimates channel state information (CSI) which includes the rank indicator (RI), the precoding matrix indicator (PMI), and the channel quality indicator (CQI), and feedbacks the CSI to the base station (BS). WebPrecoding matrix indicator (PMI) Channel quality indicator (CQI) The gNodeB uses the reported CSI to configure the target code rate, modulation, number of layers, and MIMO precoding matrix in subsequent PDSCH transmissions after a configurable delay. Generally, the gNodeB can select different transmission parameters from those a UE reports.
