AI Technical Summary
The 5G NR standard faces challenges in managing cross-link interference and inefficient duplex communication due to the inability of user equipment (UE) to accurately report adjacent channel leakage ratio (ACLR) and in-band emissions (IBE), which affects network resource utilization and reliability, especially in dynamic time division duplex (TDD) and full duplex (FDU) modes.
User equipment (UE) devices are equipped to measure and report advanced ACLR and IBE levels, providing detailed interference information to the radio access network (RAN) node, allowing for dynamic adjustment of duplex scheduling parameters to mitigate interference and improve network performance.
Enhanced UE scheduling and network resource utilization efficiency are achieved by accurately measuring and reporting ACLR and IBE, leading to improved network reliability and duplex performance.
