Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If static resource allocation is used for uplink and downlink communications, then resource allocation is simple and stable, but resource waste occurs and data transmission is delayed
Solution Approach 1:
The patent implements dynamic resource allocation by allowing the base station to flexibly adjust the ratio of uplink-dedicated regions to downlink-dedicated regions based on real-time use rates. The base station determines the ratio of UL-dedicated region to DL-dedicated region dynamically, changing it according to current traffic conditions rather than using a fixed static allocation, thereby improving resource utilization and reducing waste.
Solution Approach 2:
The patent changes the parameter of resource allocation ratio based on use rate conditions. When the uplink use rate is high and downlink use rate is low, the base station increases the UL-dedicated region ratio; conversely, when downlink use rate is high, it increases the DL-dedicated region ratio. This parameter adjustment resolves the contradiction by adapting resource allocation to actual demand, improving productivity without requiring fundamentally new allocation mechanisms.
2Productivity
If more resources are allocated to uplink communication, then uplink transmission capacity increases, but downlink resource availability decreases
Solution Approach 1:
The patent applies dynamic adjustment to the ratio of UL-dedicated region to DL-dedicated region based on real-time use rates. The base station monitors uplink and downlink resource use rates and dynamically changes the allocation ratio accordingly, allowing the system to optimize the balance between uplink transmission capacity and downlink resource availability according to actual traffic conditions rather than maintaining a fixed allocation.
Solution Approach 2:
The patent changes the allocation ratio parameter between uplink and downlink resources based on measured use rates. When uplink demand is high (high use rate), the base station increases the UL-dedicated region ratio; when downlink demand is high, it increases the DL-dedicated region ratio. This parameter change mechanism allows flexible trade-off adjustment between uplink capacity and downlink availability.
3Productivity
If more resources are allocated to downlink communication, then downlink transmission capacity increases, but uplink resource availability decreases
Solution Approach 1:
The patent implements dynamic resource allocation where the base station adjusts the ratio of UL-dedicated region to DL-dedicated region based on real-time use rates. When the downlink use rate is high and uplink use rate is low, the base station increases the DL-dedicated region ratio, thereby improving downlink transmission capacity while maintaining adequate uplink resources through the dynamic adjustment mechanism.
Solution Approach 2:
The patent changes the resource allocation ratio parameter based on use rate measurements. When downlink demand is high (high use rate), the base station increases the DL-dedicated region ratio to improve downlink transmission capacity; when uplink demand increases, it adjusts the ratio to maintain uplink availability. This parameter adjustment resolves the contradiction by adapting to actual traffic patterns.
4Productivity
If dynamic resource allocation is implemented, then resource utilization efficiency improves, but system complexity and overhead increase
Solution Approach 1:
The patent implements a dynamic resource allocation system where the base station determines the ratio of UL-dedicated region to DL-dedicated region based on use rates. The system dynamically adjusts allocations in response to changing traffic conditions, improving resource utilization efficiency. The complexity is managed by using a relatively simple decision rule based on use rate comparison rather than complex optimization algorithms.
Solution Approach 2:
The patent changes resource allocation parameters (the ratio of UL to DL dedicated regions) based on measured use rates. This parameter-based dynamic allocation improves resource utilization efficiency by adapting to actual demand. The approach maintains manageable system complexity by using direct parameter adjustment based on simple metrics (use rates) rather than complex control mechanisms.
