Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Wi-Fi technologies face challenges in effectively communicating and managing non-simultaneous transmitting and receiving (NSTR) link pairs in multi-frequency band scenarios, leading to interference and inefficient resource utilization.
Innovation Solution
A communication method and electronic device that utilize radio frames to indicate the support for multiple NSTR link pairs, using indication information in Beacon or Probe Response frames, and specific subfields within these frames to convey the number and configuration of NSTR link pairs, enabling efficient management and resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple frequency bands are aggregated and coordinated for high throughput transmission, then transmission rate and bandwidth are improved, but interference between links and resource management complexity increase
Solution Approach 1:
The patent segments the multi-frequency band system into multiple independent link pairs, each with its own NSTR capability indication. By dividing the complex multi-band management into manageable link-level units, the system can handle each link independently while maintaining overall coordination, thus reducing resource management complexity while preserving high throughput capabilities
Solution Approach 2:
The patent applies preliminary action by indicating NSTR link pair capabilities in advance through capability indication fields in management frames before actual data transmission occurs. This allows receiving devices to pre-configure their transmission strategies and avoid interference issues during active transmission, simplifying real-time resource management while maintaining high transmission rates
2Reliability
If NSTR link pair capability indication is implemented in multi-link scenarios, then interference management is improved, but communication protocol complexity increases
Solution Approach 1:
The patent extracts the NSTR capability indication as a separate, dedicated field within the existing capability information structure. By isolating this specific functionality into a distinct indication mechanism, the patent improves interference management through explicit capability signaling while minimizing the impact on overall protocol complexity, as the extraction is done within existing frame structures
Solution Approach 2:
The patent implements universality by designing the NSTR capability indication mechanism to work across multiple link pairs and frequency bands using a unified approach. The same indication field and interpretation rules apply regardless of the specific link configuration, reducing the need for multiple specialized protocols and thereby limiting complexity growth while providing comprehensive interference management
