Sidelink Discovery Resource Pool Allocation in 5G Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a method and apparatus to effectively allocate a transmission resource pool for transmitting a discovery message in a wireless communication system, particularly for sidelink communication in 5G networks, to support the expansion of service coverage, increase data transmission reliability, and reduce power consumption of user equipment.
Innovation Solution
The proposed solution involves a method where user equipment transmits transmission model type information and HARQ feedback information to the base station, which then determines whether to allocate a shared or dedicated resource pool for sidelink discovery messages. The base station configures and allocates the appropriate resource pool to the user equipment, enabling efficient transmission of sidelink discovery messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated resource pool is allocated for sidelink discovery messages, then data transmission reliability is improved, but device complexity and resource utilization efficiency deteriorate
Solution Approach 1:
The patent makes the sidelink discovery message transmission resource pool shareable with general sidelink communication resource pools. The base station configures a resource pool that can serve both discovery messages and general sidelink communications, eliminating the need for separate dedicated resources while maintaining reliable transmission through unified resource management and configuration.
2Device complexity
If a shared resource pool is used for sidelink discovery messages, then device complexity is reduced, but data transmission reliability deteriorates
Solution Approach 1:
The patent implements dynamic resource pool configuration where the base station can flexibly allocate and share resources between discovery messages and general sidelink communications based on actual network conditions and requirements. This dynamic sharing mechanism ensures that sufficient resources are available for reliable discovery message transmission while maintaining low complexity through unified resource pool management.
3Use of energy by moving object
If resource pool allocation is optimized for sidelink discovery messages, then power consumption is reduced, but service coverage expansion capability deteriorates
Solution Approach 1:
The patent optimizes power consumption by dynamically adjusting resource pool parameters such as time-frequency resource allocation, transmission power levels, and resource pool configuration based on actual sidelink discovery requirements. This parameter optimization reduces unnecessary power consumption while maintaining the system's ability to expand service coverage through efficient resource utilization and adaptive configuration.
