Wireless Resource Power Control for Blocking Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio resource management systems face issues with blocking interference due to insufficient power suppression in spectrum spreading, leading to reduced signal-to-interference-plus-noise ratio and diminished spectrum spreading gain, as they rely on theoretical constraints that do not account for actual spatial isolation degrees.
Innovation Solution
A method and apparatus that dynamically adjust transmit power based on spatial isolation degree and received power detection, ensuring the sum of powers received at the receive end does not exceed a blocking threshold, thereby eliminating blocking interference and maximizing spectrum spreading gain.

Engineering Contradiction Analysis
1Object-affected harmful factors
If power is reduced at the transmit end based on theoretical constraints, then blocking interference at the receive end is suppressed, but transmit power in the spread area greatly decreases and signal to interference plus noise ratio decreases
Solution Approach 1:
The patent implements dynamic power adjustment by continuously monitoring received power at the receive end and adapting transmit power accordingly. The system transitions from static theoretical power constraints to dynamic real-time power control, allowing the transmit end to adjust power levels based on actual channel conditions and spatial isolation degrees, thereby maintaining signal quality while suppressing blocking interference.
Solution Approach 2:
The patent establishes a feedback mechanism where the receive end measures received power and sends measurements back to the transmit end, which then adjusts transmit power based on this feedback. This closed-loop control system enables the transmit end to respond to actual interference conditions rather than relying on worst-case theoretical constraints, optimizing the balance between interference suppression and signal quality.
2Object-affected harmful factors
If power is reduced at the transmit end based on theoretical constraints, then blocking interference at the receive end is suppressed, but experience gain brought by the spread area greatly declines
Solution Approach 1:
The system dynamically adjusts power levels based on actual spatial isolation measurements rather than applying fixed theoretical constraints. This allows the spectrum spreading gain to be fully utilized in scenarios with good spatial isolation while only applying necessary power reduction when actual interference thresholds are approached, thereby maintaining reliability and experience gain.
Solution Approach 2:
The patent changes the control parameter from fixed theoretical power constraints to dynamic received power measurements. By monitoring actual received power levels and adjusting transmit power based on these measurements, the system optimizes the balance between blocking interference suppression and spectrum spreading gain, avoiding unnecessary power reduction that would diminish spreading benefits.
3Object-affected harmful factors
If strictest condition is used for power reduction, then blocking interference is eliminated, but transmit power is excessively reduced
Solution Approach 1:
The system replaces static strictest condition constraints with dynamic real-time power adjustment based on actual received power measurements. This allows transmit power to be reduced only to the extent necessary to eliminate blocking interference in each specific scenario, rather than applying excessive uniform power reduction, thereby maintaining transmit efficiency and productivity.
Solution Approach 2:
The patent changes the power control parameter from fixed strictest condition thresholds to dynamic received power measurements. This enables the system to adapt power levels to actual channel conditions, reducing power only when and by the amount necessary to eliminate blocking interference, thus avoiding excessive power reduction and maintaining high transmit efficiency.

AI summary
This application discloses a radio resource management method and apparatus, a storage medium, and a computer program. Received power detection is performed, by using a first bandwidth unit, in a downlink frequency range corresponding to a receive end, to obtain a received power corresponding to each of at least one first bandwidth unit. A spatial isolation degree between a transmit end and the receive end is obtained based on a system transmit power at the receive end and the received power corresponding to each of the at least one first bandwidth unit. A transmit power corresponding to at least one resource unit is obtained based on the spatial isolation degree and a power suppression degree that corresponds to the at least one resource unit, such that a sum of powers received by the receive end on all resource units is less than or equal to a blocking threshold. Therefore, a power at the transmit end can be dynamically adjusted, thereby eliminating blocking interference at the receive end, and maximizing a gain of spectrum spreading.
