Engineering Contradiction Analysis
1Productivity
If traditional reference signal transmission methods are used, then beam refinement can be performed, but network resource consumption and overhead increase
Solution Approach 1:
The patent combines multiple reference signal transmissions into a single burst that is received by multiple beams simultaneously using frequency division multiplexing. This merging approach allows the network to transmit reference signals for multiple beams in one time window, reducing the total number of transmission occasions and thereby decreasing network resource consumption and overhead while maintaining beam refinement functionality.
Solution Approach 2:
The patent introduces frequency division multiplexing as an additional dimension to the traditional time-sequential reference signal transmission. By multiplexing multiple reference signals across different frequency resources within a single time window, the system achieves parallel processing of beam refinement operations, reducing the time required and network resources consumed while improving spectral efficiency.
2Productivity
If traditional reference signal transmission methods are used, then beam refinement can be performed, but transmission duration increases
Solution Approach 1:
The patent merges multiple reference signal transmissions into a single burst that can be received by multiple beams simultaneously. This consolidation reduces the total transmission duration required for beam refinement procedures, enabling more frequent beam management operations without increasing the overall time consumption.
Solution Approach 2:
The patent enables continuous and efficient beam refinement by transmitting multiple reference signals in a single burst using frequency division multiplexing. This approach eliminates gaps between reference signal transmissions and maintains continuous useful action, allowing the system to perform beam management more frequently and efficiently.
3Productivity
If multiple reference signals are transmitted via multiple beams using frequency division multiplexing during a single burst, then spectral efficiency increases, but device complexity increases
Solution Approach 1:
The patent applies frequency division multiplexing as an additional dimension to reference signal transmission, allowing multiple beams to be multiplexed in the frequency domain rather than requiring complex spatial processing. This approach improves spectral efficiency by utilizing frequency resources more effectively while the beam management complexity remains controlled through standardized multiplexing procedures.
