Engineering Contradiction Analysis
1Ease of operation
If electronic apparatuses are randomly selected for grouping in MU-MIMO scheme, then the grouping process is simple and quick, but the data rate significantly decreases due to inefficient configuration
Solution Approach 1:
The system performs preliminary actions by having each electronic apparatus transmit channel information and communication performance metrics before the grouping decision is made. The transceiver receives and stores this information in advance, enabling optimal grouping without requiring real-time complex calculations during the actual data transmission, thus resolving the contradiction between simple quick grouping and high data rate.
Solution Approach 2:
The system implements feedback mechanisms where electronic apparatuses provide channel information and communication performance metrics to the transceiver. Based on this feedback, the transceiver makes informed grouping decisions that optimize data rates while maintaining manageable complexity through iterative refinement of group configurations.
2Productivity
If optimal grouping is performed by evaluating communication performance metrics from all electronic apparatuses, then data transmission efficiency is improved, but the overhead for channel information acquisition increases
Solution Approach 1:
The system applies partial action by having electronic apparatuses transmit channel information and communication performance metrics only when needed for grouping decisions, rather than continuously acquiring all possible information. This selective information acquisition balances the need for optimal grouping with the desire to minimize overhead and energy consumption.
Solution Approach 2:
The system changes parameters by using communication performance metrics as evaluation criteria for grouping decisions. Instead of relying solely on channel information, the system incorporates performance-based parameters that guide the grouping process, enabling efficient data transmission while reducing the amount of channel information that needs to be acquired and processed.
3Measurement precision
If channel information is received from multiple electronic apparatuses for optimal grouping, then grouping accuracy is improved, but the time required for information acquisition and processing increases
Solution Approach 1:
The system performs preliminary information acquisition by having electronic apparatuses transmit channel information and communication performance metrics before the grouping decision is made. This advance preparation allows the transceiver to process information in batches rather than in real-time, improving grouping accuracy while reducing the time required for information acquisition and processing during critical transmission periods.

AI summary
A transceiver includes a communicator connected to a plurality of electronic apparatuses which receives channel information on a channel between a first electronic apparatus and the transceiver from the first electronic apparatus selected among the plurality of electronic apparatuses, and a controller configured to select a second electronic apparatus among the plurality of electronic apparatuses based on information received from each of the plurality of electronic apparatuses when information indicating communication performance in the case in which each of the one or more electronic apparatuses is in the same group as the first electronic apparatus, is received from each of the plurality of electronic apparatuses through the communicator, group the first and second electronic apparatuses into the same group when the channel information on a channel between the second electronic apparatus and the transceiver is received from the second electronic apparatus, and control the communicator to transmit data.
