Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of mobile wireless communication devices transmitting AFC requests to identify allowed transmit powers in the 6 GHz wireless band is saturating cellular networks and AFC servers, necessitating a reduction in the number of such requests and responses to optimize resource usage.
Innovation Solution
Implementing a system where wireless devices transmit AFC requests for nearest neighboring entities and set transmit powers based on received AFC power level indications, limiting requests to specific events, and using cellular network components to manage AFC responses, thereby reducing the overall number of requests sent to AFC servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If mobile wireless devices transmit AFC requests to identify allowed transmit powers in the 6 GHz band, then accurate transmit power settings are achieved, but the number of requests saturates cellular networks and AFC servers
Solution Approach 1:
The system performs preliminary actions by having wireless devices store AFC power level indications and neighboring entity information in local memory during initial AFC requests. This cached information is then reused for subsequent transmit power determinations, eliminating the need to repeatedly query the AFC server for the same location data, thus reducing network saturation while maintaining accurate power settings.
Solution Approach 2:
The patent implements local quality by enabling wireless devices to autonomously determine transmit power using locally stored AFC power level indications and neighboring entity information. Instead of centralizing all decision-making at the AFC server, the system distributes intelligence to individual devices, allowing them to make local transmit power decisions based on their specific geographic context, reducing the burden on network infrastructure.
2Productivity
If the number of AFC requests is reduced to optimize resource usage, then network saturation is alleviated, but the ability to maintain accurate transmit power settings may be compromised
Solution Approach 1:
The system implements feedback mechanisms where wireless devices monitor changes in their operational environment (such as movement to new locations or changes in neighboring entities) and only initiate new AFC requests when such changes occur. This event-driven approach ensures that transmit power settings remain accurate by updating only when necessary, while minimizing unnecessary requests that would consume network resources.
Solution Approach 2:
Wireless devices perform preliminary actions by caching AFC power level indications and neighboring entity information in local memory. This pre-stored data enables devices to maintain accurate transmit power settings for extended periods without contacting the AFC server, ensuring measurement precision is preserved while significantly reducing the frequency of network requests.
3Reliability
If wireless devices continuously transmit AFC requests to maintain accurate power levels, then transmit power settings remain up-to-date, but bandwidth and server processing resources are consumed
Solution Approach 1:
The system transitions from continuous AFC request transmission to periodic action by triggering requests only at specific events such as device movement to new geographic locations, changes in neighboring entity detection, or handover between cellular networks. This event-driven periodic approach maintains reliable transmit power settings by updating only when environmental conditions change, while dramatically reducing overall request frequency and resource consumption.
Solution Approach 2:
Wireless devices perform self-service by autonomously determining when AFC requests are necessary based on their own operational context and stored historical data. Devices independently assess whether their current location and environment require updated power settings, eliminating the need for continuous server-pushed updates or device-initiated periodic queries, thus reducing bandwidth and processing resource consumption while maintaining reliability.

AI summary
This disclosure provides systems and methods for use of automated frequency coordination (AFC) to manage transmission power and frequencies. In some implementations, a device transmits, to a network entity, an AFC request. The device receives, from the network entity, an AFC response, the AFC response including an AFC power level indication of one or more nearest neighboring entities. The device sets a transmit power of the device based at least in part on the AFC power level indication of at least one of the one or more nearest neighboring entities, and the device transmits at the transmit power. In some instances, the device transmits a first number of AFC requests during a first instance of travelling along a path and transmits a second number of AFC requests less than the first number of AFC requests during one or more successive instances after the first instance of travelling along the path.
