Broadcast Channel Control for Wireless Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in maintaining older network systems to fully exploit new device capabilities, as they are not easily updated to accommodate expanding mobile device features, leading to inefficiencies in resource allocation and interference management.
Innovation Solution
The implementation of techniques for assigning, identifying, and controlling broadcast transmissions by generating a broadcast channel control message and allocating broadcast flows to physical resources, using error correction codes and modulation hierarchies to optimize resource usage and reduce interference across multiple access wireless communication systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If older wireless network systems are maintained to support new device capabilities, then device capability utilization is improved, but system complexity and difficulty of updating increase
Solution Approach 1:
The patent segments broadcast services into multiple broadcast flows that can be independently scheduled and controlled. Each flow can be assigned to different physical resources (subcarriers, time slots, codes) allowing selective activation based on device capabilities, thus utilizing new device features without requiring complete system redesign.
Solution Approach 2:
The system implements dynamic scheduling where broadcast flows can be allocated to different physical resources based on current network conditions and device capabilities. The scheduler can adaptively assign resources in real-time, allowing the system to exploit new device capabilities while maintaining backward compatibility with older devices.
2Productivity
If broadcast transmissions are assigned to physical resources, then resource allocation efficiency is improved, but interference between broadcasts increases
Solution Approach 1:
The patent divides the broadcast transmission system into multiple independent broadcast flows, each of which can be assigned to different physical resources. This segmentation allows efficient resource utilization while enabling interference management through selective resource allocation and scheduling.
Solution Approach 2:
Different broadcast flows are assigned different physical resources (subcarriers, time slots, or codes) based on their specific requirements and the current network state. This local differentiation of resource allocation optimizes efficiency for each flow while minimizing interference between different broadcasts.

AI summary
Methods and apparatus for assigning, identifying and controlling broadcast transmissions are disclosed. A broadcast flow is assigned to a broadcast logical channel of the physical resources of a wireless communication channel. A broadcast channel control message indicative of parameters of the broadcast logical channel is generated. Upon receipt, the broadcast channel control message is processed and used to accordingly process the received broadcast transmission.
