Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in power offset settings due to the limited number of reference E-TFCI values, leading to inaccurate gain factors and reduced system performance, particularly in varying radio conditions.
Innovation Solution
A method and arrangement in a first node that receives a signal from a second node, acquires statistics on frequently used parameter values for the requested service, and selects the most frequently used parameter value to provide a more accurate power offset, optimizing radio resource utilization and improving system capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a limited set of reference E-TFCI values is used, then the system complexity is reduced, but the measurement precision of power offset settings deteriorates
Solution Approach 1:
The patent applies dynamics by making the reference E-TFCI selection adaptive rather than static. The system dynamically selects reference E-TFCI values based on service type and buffer size conditions, allowing the reference set to change according to operational context. This resolves the contradiction by enabling accurate power offset settings across different scenarios without requiring a universally comprehensive reference set for all possible conditions.
Solution Approach 2:
The patent implements local quality by providing different reference E-TFCI sets for different service types (e.g., voice vs. data services) and different buffer size ranges. Each local condition receives optimized reference values tailored to its specific requirements, improving measurement precision for power offset settings in each local context while keeping the overall system complexity manageable through localized optimization rather than global comprehensiveness.
2Manufacturing precision
If service-specific reference E-TFCI values are implemented, then the manufacturing precision of power offset settings is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the reference E-TFCI configuration into separate service-specific sets. Instead of managing one large comprehensive set, the system segments references into distinct groups for different service types (voice, data, video conferencing, etc.) and buffer size ranges. This segmentation improves manufacturing precision for each service category while reducing the complexity burden on any single reference set, making the overall management more tractable.
Solution Approach 2:
The patent implements preliminary action by pre-configuring service-specific reference E-TFCI sets during system setup or initialization. The appropriate reference set for a given service type is determined and prepared in advance, before actual data transmission begins. This preliminary configuration ensures high precision power offset settings are immediately available when needed, while the complexity of managing multiple sets is handled during the setup phase rather than during real-time operation.
3Adaptability or versatility
If interpolation methods are used for power offset calculation, then the adaptability to different E-TFCI values is improved, but the computation time increases
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing power offset values for reference E-TFCI configurations. Instead of performing complex interpolation calculations in real-time for every E-TFCI value, the system prepares reference power offset data in advance based on the service-specific reference E-TFCI sets. When a specific E-TFCI is needed, the system can directly use or make minor adjustments to pre-computed values, significantly reducing computation time while maintaining adaptability through the service-specific reference framework.
4Reliability
If more reference E-TFCI values are signaled, then the reliability of power offset settings is improved, but the information transmission overhead increases
Solution Approach 1:
The patent implements local quality by signaling different numbers and types of reference E-TFCI values for different service types. For services requiring high reliability (e.g., voice communications), the system signals more reference values or more frequently updated references. For services with lower reliability requirements, fewer references are signaled, reducing overhead. This localized approach to reference signaling optimizes the balance between reliability and overhead for each specific service context rather than applying a uniform approach to all services.

AI summary
Method and arrangement in a first node, for providing a parameter value. The parameter value is associated with the transmission power of a radio signal. The radio signal is sent from a second node, to be received by the first node. The radio signal is sent over a first channel and a second channel. The method comprises the step of receiving a signal from the second node. The signal comprises a transfer service request for a first type of service. Further, the method comprises the step of obtaining the parameter value, based on the requested transfer service of the second node. The parameter value is associated with the transmission power level of the first channel and the transmission power level of the second channel.
