Base Station Channel Switching for Wireless Anomaly Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio communication systems experience anomalies due to increased channel occupancy time by mobile stations with lower data rates, leading to reduced throughput and resource shortages, preventing simultaneous data transmission from stations with higher data rates.
Innovation Solution
Implement a method where base stations and mobile stations use Channel Quality Indication (CQI) information to detect anomalies, and switch from primary cellular channels to shared or open channels, such as UHF TV or ISM channels, to manage channel occupancy and prevent anomalies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile station with lower data rate occupies channels for longer time to transmit equivalent data, then the lower data rate mobile station can complete its transmission, but the overall cell capacity and throughput of higher data rate mobile stations are significantly reduced
Solution Approach 1:
The patent segments the channel allocation by identifying specific mobile stations experiencing anomalies and separating them from the general scheduling pool. The base station divides the cell into normal mobile stations and anomaly-prone mobile stations, applying different scheduling strategies to each segment. This allows higher data rate stations to be served efficiently while providing extended resources to lower data rate stations that need it.
Solution Approach 2:
The patent implements dynamic scheduling where the base station continuously monitors channel quality indicators (CQI) and adjusts channel occupancy time and resource allocation in real-time. Mobile stations are dynamically reclassified between normal and anomaly-prone categories based on current channel conditions, allowing the system to adapt resource distribution to current needs rather than using static allocation.
2Quantity of substance
If channel occupancy time is increased for mobile stations with lower data rates, then they can transmit larger amounts of data, but radio communication anomalies occur that prevent simultaneous transmission by other mobile stations
Solution Approach 1:
The patent segments mobile stations into different groups based on their transmission characteristics and channel conditions. Anomaly-prone mobile stations are separated from normal stations, allowing the system to manage their channel occupancy independently. This segmentation prevents the channel occupancy of one group from negatively impacting the simultaneous transmission capability of the other group.
Solution Approach 2:
The patent changes the parameter of channel occupancy time dynamically based on mobile station classification. Normal mobile stations receive standard channel occupancy time, while anomaly-prone mobile stations receive extended channel occupancy time. This parameter change is applied selectively to maintain overall system reliability while enabling higher data transmission volumes for stations that need it.
3Ease of operation
If resources are allocated to mobile stations with lower data rates, then they can transmit data, but resource shortage occurs that prevents other mobile stations from transmitting data simultaneously
Solution Approach 1:
The patent applies local quality by providing different resource allocation quality to different mobile station groups. Anomaly-prone mobile stations receive enhanced resource allocation including extended channel occupancy time and priority scheduling, while normal mobile stations receive standard resource allocation. This localized enhancement ensures that stations needing assistance get the support they require without depriving other stations of adequate resources.
Solution Approach 2:
The patent changes resource allocation parameters selectively based on mobile station classification. For anomaly-prone stations, parameters such as channel occupancy time, scheduling priority, and resource block allocation are increased. For normal stations, standard parameters are maintained. This selective parameter adjustment resolves the contradiction by providing enhanced resources only where needed while preserving overall resource availability.

AI summary
A base station and a mobile station for processing wireless communication with each other, and a method for controlling the same are provided. The method for controlling a base station which performs radio communication with a mobile station includes starting radio communication via at least one arbitrary mobile station and a predetermined cellular channel; receiving Channel Quality Indication (CQI) information from the mobile station; determining whether a radio communication anomaly occurs between a specific mobile station from among the at least one arbitrary mobile station and the base station by using the received CQI information; and when determining that the radio communication anomaly occurs with the specific mobile station, controlling to interrupt the radio communication via the predetermined cellular channel and perform radio communication via the specific mobile station and either a shared channel or an open channel.
