Wireless Communication Resource Allocation for Interference Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G NR communication systems face challenges in efficiently supporting simultaneous unicast and broadcast services due to increasing service requirements and inter-site interference, necessitating improved resource allocation and interference management.
Innovation Solution
The method involves receiving and transmitting UE assistance information to enable simultaneous unicast and broadcast services on a common physical channel, utilizing RAN-based single frequency network (SFN) and single cell-point to multipoint (SC-PTM) transmission, allowing for dynamic resource configuration and adaptive modulation to optimize service delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If unicast and broadcast services are transmitted simultaneously on a common physical channel, then resource efficiency is improved, but inter-site interference increases
Solution Approach 1:
The patent implements dynamic resource allocation where the network node receives UE assistance information and dynamically configures resources for unicast and broadcast services based on current channel conditions and service requirements. This allows the system to adapt transmission parameters in real-time to balance resource efficiency with interference management across different sites.
2Adaptability or versatility
If broadcast/multicast services are provided over a single cell with dynamically adjusted areas, then service adaptability is improved, but device complexity increases
Solution Approach 1:
The patent segments the broadcast/multicast service area into multiple cells, allowing independent configuration and dynamic adjustment of service areas on a per-cell basis. This segmentation enables flexible adaptation to different user distributions and service requirements while distributing the complexity management across multiple manageable cell units rather than a single complex system.

AI summary
A method of wireless communication is provided. The method includes receiving UE assistance information from user equipment (UEs); and transmitting, by the network node, unicast and a broadcast service simultaneously on a common physical channel based on the UE assistance information. With this method, better resource efficiency and flexible transmission are realized based on the UE assistance information.
