Engineering Contradiction Analysis
1Device complexity
If a single signal format is used to code control signals for both single-codeword and multiple-codeword MIMO transmissions, then the system structure is simplified, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent segments the control signal coding into distinct formats: a first signal format for single-codeword MIMO transmissions and a second signal format for multiple-codeword MIMO transmissions. This segmentation allows each format to be optimized for its specific transmission type, improving resource utilization efficiency while maintaining manageable system complexity through structured differentiation.
2Productivity
If distinct signal formats are used to code control signals for single and multiple codeword transmissions, then resource utilization efficiency is improved, but system complexity increases
Solution Approach 1:
The patent applies local quality by assigning different signal format characteristics to different transmission scenarios: the first signal format is optimized for single-codeword transmissions while the second signal format is optimized for multiple-codeword transmissions. This localized optimization improves resource utilization efficiency for each specific case without requiring complete system redesign.
3Ease of manufacture
If control signals are inefficiently coded, then system implementation is simpler, but data transmission efficiency deteriorates
Solution Approach 1:
The patent changes key parameters of the control signal coding by introducing distinct signal formats with different structures and characteristics optimized for single-codeword versus multiple-codeword transmissions. This parameter differentiation improves data transmission efficiency while maintaining implementation feasibility through systematic design.

AI summary
The present invention relates to a method for data transmission in a communication system. The method includes determining, at the transmitter, whether to transmit data signal using a single codeword or two codewords. When it is determined that the single codeword transmission is used, coding, by the transmitter, a control signal by using a first signal format, with the control signal coded by the first signal format carrying information regarding the single codeword. When it is determined that the two codewords transmission is used, coding, by the transmitter, the control signal by using a second signal format, with the control signal coded by the second signal format carrying information regarding both of the two codewords. The method also includes transmitting the data signal and the control signal according to the determined transmission format from the transmitter to the receiver.
