WebNov 2, 2024 · The PHY is broken into low-PHY and high-PHY; low-PHY stays in the RUs and high-PHY in the DUs. As a result, the bandwidth required on the front-haul interface is about 20 Gb for 100 MHz bandwidth with some MIMO capabilities. Moving from the DUs to the CU typically means an upper layer split or HLS—Option 2. WebApply High-PHY operations and then extract IQ data in 7.2x split, which is the data coming from the resource grid. Compress the data using one of the compression methods available.
