Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks face interference issues due to noise generated in adjacent frequency bands by power transmission from wireless access nodes, making it difficult to balance and dynamically modify transmit power based on the requirements of connected devices.
Innovation Solution
A method for a wireless access node to dynamically modify transmit power based on Reference Signal Receive Power (RSRP) values by identifying distances and normalizing RSRP values for connected devices, determining a target RSRP, and adjusting transmit power to deliver the target RSRP, thereby minimizing noise and interference in adjacent frequency bands.

Engineering Contradiction Analysis
1Object-affected harmful factors
If transmit power is limited in the first frequency band, then noise and interference in adjacent frequency bands is minimized, but service quality for wireless communication devices connected to the first frequency band deteriorates
Solution Approach 1:
The patent implements dynamic transmit power adjustment by continuously monitoring RSRP values and device distances, allowing the system to adapt power levels in real-time based on current network conditions rather than using static power limits. This enables the system to optimize the balance between minimizing interference and maintaining service quality dynamically.
Solution Approach 2:
The patent applies different transmit power levels to different wireless communication devices based on their individual RSRP values and distances from the access node. Instead of uniformly limiting power across all devices, the system tailors power allocation to each device's specific requirements, ensuring adequate service quality for devices that need it while minimizing interference from devices that can operate at lower power.
2Reliability
If transmit power is increased to improve service quality for wireless communication devices, then noise and interference in adjacent frequency bands increases
Solution Approach 1:
The patent employs a feedback mechanism where the wireless access node continuously monitors RSRP values reported by wireless communication devices and uses this information to adjust transmit power levels. This closed-loop control enables the system to increase power only when and where it is needed to maintain service quality, rather than uniformly increasing power across all transmissions.
Solution Approach 2:
The patent changes the transmit power parameter dynamically based on RSRP measurements and device distance calculations. By adjusting this key parameter in response to changing network conditions, the system can optimize service quality while minimizing unnecessary power increases that would generate interference in adjacent bands.
3Device complexity
If uniform transmit power is used for all wireless communication devices, then system complexity is reduced, but network performance deteriorates due to inability to balance power requirements of devices at different distances
Solution Approach 1:
The patent modifies the transmit power parameter based on RSRP values and device distances, creating a adaptive power management system. This approach improves network performance by accounting for variations in device locations and signal conditions, while the use of standardized RSRP measurements and systematic adjustment procedures keeps the added complexity manageable.

AI summary
The technology disclosed herein enhances the operation of a wireless access node to dynamically provide transmit power based on Reference Signal Receive Power (RSRP). In one implementation, a method of operating a wireless access node includes transmitting first signals with wireless communication devices using a first transmit power, and identifying RSRP values for the wireless communication devices. The method further includes identifying distances between the wireless access node and each wireless communication device, normalizing the RSRP values based on the distances, identifying a target RSRP based on the normalized RSRP values, and determining a second transmit power based on the target RSRP. The method further provides transmitting second signals to the wireless communication devices using the second transmit power.
