AI Technical Summary

Technical Problem

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.

Method used

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.

Benefits of technology

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.

Abstract

In a system, apparatus, method, and non-transitory computer-readable medium, a UE device obtains a radiation reporting configuration from at least one radio access network (RAN) node, the radiation reporting configuration including at least one measurement parameter and at least one reporting trigger condition, determines whether at least one reporting trigger condition is satisfied, performs an uplink (UL) transmission to at least one RAN node based on at least one UL transmission parameter, measures the UL radiation of the corresponding UL transmission based on at least one measurement parameter, and transmits a radiation report to at least one RAN node based on the measured UL radiation and at least one UL transmission parameter.
