ENTV Capability Signaling for 5G Broadcast-Unicast Coexistence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication networks face interference and co-existence issues between broadcast and unicast transmissions for ENTV services, particularly in scenarios where both modes operate in the same frequency band.
Innovation Solution
The method involves generating an ENTV capability message by a user equipment (UE) indicating its ENTV parameters, such as supported bands, access spectrum location, subcarrier spacing, and buffer capability, and sending it to a Next Generation NodeB (gNB) in a 5G-NR RAN. This message enables the gNB to determine appropriate radio resource configurations for the UE to reduce interference and mitigate co-existence issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both broadcast and unicast transmissions operate in the same frequency band for ENTV services, then service coverage and accessibility are improved, but interference between the two modes increases
Solution Approach 1:
The patent segments the frequency band into distinct resource pools for broadcast and unicast transmissions. By dividing the available spectrum resources and assigning separate time-frequency resources to each transmission mode, the system enables both modes to coexist in the same frequency band while minimizing mutual interference.
Solution Approach 2:
The patent implements dynamic resource allocation where the gNB can flexibly assign time-frequency resources to broadcast or unicast modes based on current network conditions, UE capabilities, and service requirements. This dynamic scheduling allows the system to adapt resource distribution in real-time to optimize both coverage and reduce interference.
2Adaptability or versatility
If UEs support both broadcast and unicast reception modes, then service flexibility is improved, but co-existence issues on UEs increase
Solution Approach 1:
The patent implements preliminary action by having UEs report their ENTV capabilities (broadcast reception, unicast reception, or both) to the gNB before service delivery. The gNB uses this advance information to pre-configure appropriate resource allocations and transmission modes, preventing co-existence conflicts before they occur.
Solution Approach 2:
The patent establishes a feedback mechanism where UEs provide capability information to the gNB, and the gNB responds with configured resource allocations. This closed-loop feedback enables the network to adapt resource assignment based on actual UE capabilities, reducing co-existence issues while maintaining service flexibility.
3Measurement precision
If ENTV capability messages include detailed parameters, then resource configuration precision is improved, but message overhead increases
Solution Approach 1:
The patent implements a universal ENTV capability message structure that can convey multiple types of information (broadcast capability, unicast capability, supported bands, subcarrier spacing preferences) in a single standardized message format. This multi-functional message design provides precise resource configuration information while avoiding the need for multiple separate signaling messages.
