Multi-Antenna Channel Selection via Decoder Quality Values
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in selecting the optimal transmission channel for maintaining high connection quality, especially in hybrid networks with multiple antenna systems and diverse transmission technologies, leading to inefficiencies in resource usage and handover processes.
Innovation Solution
The method involves using a multi-antenna system where both the radio base station and mobile terminal have at least two antennas, forming multiple transmission paths and channels, with a decoder to determine channel-specific quality values for selecting the best transmission path based on physical properties and channel parameters, rather than just signal-specific values like power level or signal-to-noise ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If signal strength or signal-to-noise ratio is used for channel selection, then the handover process can be controlled, but the connection quality cannot be optimized in hybrid networks with multiple antenna systems and diverse transmission technologies
Solution Approach 1:
The patent changes the parameters used for channel quality assessment from traditional signal strength and signal-to-noise ratio to channel-specific quality values derived from physical properties and channel parameters of multiple transmission paths. This allows for more accurate and optimized connection quality assessment in hybrid networks with diverse transmission technologies and multi-antenna systems.
2Productivity
If traditional handover processes are used, then channel switching can be implemented, but resource usage efficiency and spectral efficiency are reduced
Solution Approach 1:
The patent implements a feedback mechanism where channel-specific quality values are continuously determined and compared for multiple transmission channels. Based on this feedback, the system selects the optimal transmission path and adjusts handover decisions, thereby improving resource usage efficiency and spectral efficiency while reducing power consumption through more informed channel selection.
3Adaptability or versatility
If multiple transmission channels with different technologies are available, then communication versatility is improved, but the complexity of selecting the optimal channel increases
Solution Approach 1:
The patent segments the channel selection process by evaluating each transmission channel independently through its specific quality values derived from physical properties and channel parameters. This segmentation allows the system to handle multiple transmission technologies and antenna configurations systematically, improving adaptability while managing complexity through structured evaluation of individual channels.

AI summary
The invention relates to a method for selecting transmission channels in a multi-antenna network radio connection in which data are transmitted by means of radio signals between a radio base station (2, 120a, 120b, 130a, 140a) and a mobile terminal (17, 170, 1700), wherein the radio base station (2, 120a, 120b, 130a, 140a) and the mobile terminal (17, 170, 1700) each have at least two antennas (4, 5, 6, 7), by means of which a plurality of transmission paths (8, 9, 10, 11) are formed for the radio connection and at least two transmission channels are formed for the data transmission, which transmission channels each use one or more of the transmission paths (8, 9, 10, 11) in accordance with a channel matrix. The mobile terminal (17, 170, 1700) has at least one decoder (16), by means of which radio signals received by at least one of the terminal antennas (6, 7) can be decoded in order to obtain the data. By means of the transmission channel section, it is decided which transmission path or transmission paths (8, 9, 10, 11) and/or which communication technology is used for the transmission of the data between the radio base station (2, 120a, 120b, 130a, 140a) and the mobile terminal (17, 170, 1700). The following steps are provided: mobile radio signals for first data are transmitted in at least one communication system technology from the mobile radio base station (2, 120a, 120b, 130a, 140a) to the mobile terminal (17, 170, 1700) via the transmission paths (8, 9, 10, 11), the mobile radio signals are fed to the decoder (16) separately for each transmission channel, the decoder (16) decodes the mobile radio signals and thus obtains the first data separately for each transmission channel, by means of the decoded first data, at least one quality value is calculated separately for each transmission channel, which quality value is representative of a quality of the data transmission via the respective transmission channel, and on the basis of a comparison of the quality values of the transmission channels, the transmission channel selection for the subsequent transmission of second data, which form payload data, is performed.
