Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face low carrier spectrum utilization due to fixed time periods for signal transmission and reception, leading to inefficient use of resources, especially in asymmetric service scenarios where uplink and downlink data volumes differ significantly.
Innovation Solution
Implementing a wireless communication method that utilizes at least three timeslots, including full-duplex, downlink, and uplink timeslots, allowing flexible signal sending and receiving, with adaptive allocation based on data volume thresholds to optimize spectrum usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed time periods are used for signal transmission and reception in TDD system, then interference between sending and reception is avoided, but carrier spectrum utilization is reduced
Solution Approach 1:
The patent introduces dynamic timeslot configuration where timeslots can be flexibly switched between full-duplex mode (simultaneous sending and receiving) and half-duplex mode (separated sending and receiving). This dynamic adjustment allows the system to adapt to varying traffic conditions, improving spectrum utilization while maintaining interference avoidance through appropriate mode selection.
Solution Approach 2:
The patent changes the parameter of timeslot functionality from fixed to variable. Each timeslot can be configured with different attributes (full-duplex or half-duplex) based on traffic requirements. This parameter change enables the system to optimize spectrum usage by allocating full-duplex timeslots for asymmetric traffic and half-duplex timeslots for symmetric traffic scenarios.
2Reliability
If spectrum-paired carriers with guard band are used in FDD system, then mutual interference between receiving device and neighboring sending device is prevented, but carrier spectrum utilization is reduced especially for asymmetric services
Solution Approach 1:
The patent makes the timeslot structure universal by designing it to support multiple functions: full-duplex timeslots for simultaneous bidirectional communication, half-duplex timeslots for separated communication, and flexible switching between modes. This multi-functionality allows the same timeslot framework to serve both symmetric and asymmetric traffic requirements, improving overall carrier spectrum utilization.
Solution Approach 2:
The patent introduces dynamic configuration of timeslot types based on real-time traffic conditions. When asymmetric traffic is detected, the system can allocate more full-duplex timeslots to maximize spectrum usage. When symmetric traffic predominates, half-duplex timeslots are used to prevent interference. This dynamic adaptation resolves the contradiction between interference prevention and spectrum utilization.
