Innovation Solution
A method and apparatus for high-capacity transmission networks are developed by configuring a terminal-centric cluster using multiple radio access points, employing techniques like intra-frequency multi-connectivity, cooperative communication, frequency aggregation, dual-connectivity, and single frequency network functions to form a cluster based on measurement information and signal strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If ultra-high frequency bands are utilized for data transmission, then bandwidth and transmission capacity are improved, but propagation loss increases severely
Solution Approach 1:
The patent combines multiple radio access points into a cooperative cluster to transmit data to a terminal. By merging the transmission resources of multiple access points, the system achieves high-capacity transmission using ultra-high frequency bands while compensating for severe propagation loss through coordinated multi-point transmission.
2Quantity of substance
If a terminal-centric cluster is configured using multiple radio access points, then transmission capacity is improved, but system complexity increases
Solution Approach 1:
The patent segments the PDCP function into two parts: the first partial PDCP function is performed by the central unit, and the second partial PDCP function is performed by the radio access points. This segmentation reduces the processing burden on individual access points while maintaining high transmission capacity through coordinated operation.
3Reliability
If cluster configuration is based on measurement information and signal strength, then communication reliability is improved, but measurement and configuration time increases
Solution Approach 1:
The patent performs preliminary measurements of signal strength from multiple radio access points before configuring the terminal-centric cluster. By conducting these measurements in advance and using the results to pre-determine the optimal cluster configuration, the system ensures reliable communication while minimizing configuration delays during actual data transmission.
