Broadcast Service Reporting for 5G Unicast Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G systems, the lack of a defined Receive Only Mode (ROM) service identification for terminals receiving both unicast and broadcast services leads to potential exceeding of processing capabilities, as current reporting methods do not allow network devices to accurately schedule services, risking incomplete service reception.
Innovation Solution
Terminals determine and report specific broadcast service information, including service identification, index, and physical resource location to network-side devices, enabling the network to schedule unicast and broadcast services efficiently through time or frequency division multiplexing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the terminal reports broadcast service information using the current 4G reporting mode, then the terminal can send service reports to the network device, but the network device cannot determine whether the terminal is receiving broadcast service while receiving unicast service, leading to inaccurate service scheduling
Solution Approach 1:
The patent introduces an intermediary indicator (first indication information) that the network device sends to the terminal. This indicator enables the terminal to selectively report broadcast service information only when receiving both unicast and broadcast services simultaneously. The intermediary mechanism resolves the ambiguity in service type identification without requiring complex terminal processing capability reports.
2Adaptability or versatility
If the terminal receives both unicast and broadcast services simultaneously, then the terminal can access multiple services, but the processing capability (reception, demodulation and other corresponding processing of a signal) may exceed the capability range supported by the terminal
Solution Approach 1:
The patent implements a feedback mechanism where the terminal reports broadcast service information to the network device when receiving both unicast and broadcast services. The network device uses this feedback to adjust service scheduling, ensuring that the terminal's processing capabilities are not exceeded. This feedback loop maintains service processing reliability while enabling multi-service reception.
3Productivity
If the network device schedules unicast and broadcast services without accurate terminal capability information, then the network can perform service scheduling, but the terminal processing capability may be exceeded, causing incomplete service reception
Solution Approach 1:
The patent applies preliminary action by having the terminal proactively report broadcast service information before the network device performs scheduling. The network device receives this advance information and uses it to make informed scheduling decisions, preventing terminal capability overload while maintaining scheduling efficiency. This preliminary reporting mechanism ensures reliable service delivery.
Data Source
AI summary
An information transmission method, a scheduling method, a terminal and a network-side device are provided. The information transmission method includes: determining, by a terminal, related information of a first broadcast service; and sending, by the terminal, the related information of the first broadcast service to a network-side device; where the related information of the first broadcast service includes at least one of: a service identification of the first broadcast service; a service index of the first broadcast service; and physical resource location information of the first broadcast service.
