Broadcast Multicast Transmission Mode Selection for Lower Uplink Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current broadcast multicast services require terminal devices to indicate all interested services, leading to unnecessary uplink overheads.
Innovation Solution
Implement a communication method where the access network device determines a transmission mode for broadcast multicast services in connected, inactive, or idle states, reducing the need for terminal devices to report interest indications for other services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If terminal devices indicate interest in all broadcast multicast services, then the network can maintain comprehensive service information, but uplink overheads increase unnecessarily
Solution Approach 1:
The patent applies local quality by differentiating the information reporting requirement based on transmission mode. For first transmission mode (broadcast), terminal devices do not need to report service interest information, while for second transmission mode (multicast), terminal devices do report service interest information. This selective approach reduces overall uplink overhead while maintaining necessary service information for multicast services.
2Loss of information
If terminal devices report interest in all broadcast multicast services, then the network has complete service interest data, but communication efficiency decreases due to unnecessary signaling
Solution Approach 1:
The patent implements local quality by applying different reporting rules to different transmission modes. Terminal devices report service interest information only for second transmission mode (multicast) services, not for first transmission mode (broadcast) services. This selective reporting maintains necessary service interest data while eliminating unnecessary signaling overhead, thereby improving communication efficiency.
3Loss of information
If the network requests service interest information for all broadcast multicast services, then complete service interest data can be collected, but signaling overhead increases
Solution Approach 1:
The patent applies local quality by differentiating the information collection requirement based on transmission mode. The network requests service interest information from terminal devices only for second transmission mode (multicast) services, not for first transmission mode (broadcast) services. This selective information collection reduces signaling overhead while maintaining necessary service interest data for multicast services.

AI summary
A coordinated transmission control method, apparatus, and system. A primary access point and a secondary access point determine whether to perform coordinated transmission through inter-cell configuration parameter sharing and based on a dual decision condition of an interference test. An anti-interference beamforming manner is determined based on a specific cell configuration parameter, and whether to perform coordinated transmission is determined with reference to the dual decision condition of the interference test, wherein the primary and secondary access points learn an interference status in advance to prevent unnecessary retransmission resulting from interference caused during actual coordinated transmission.
