As such, downlink/uplink throughput may be suboptimal with the default configurations, but enhancements are actively being explored. -To achieve better E2E performance with the current implementation, we recommend the following adjustments: +For example, to achieve better E2E performance with the current implementation with Intel ACC 100 and 200 (vRAN Boost), +we recommend the following adjustments: 1. Increasing the number of LDPC decoding iterations of the L1, e.g., `max_ldpc_iterations` to 200. 2. Increasing the BLER targets of the MAC scheduler.
