Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If separate encoding is used for first information and second information in downlink control information, then the information can be independently processed and decoded, but the number of bits required increases and downlink control information overhead increases
Solution Approach 1:
The patent merges the encoding of first information (HARQ process number) and second information (new data indicator) into a single joint encoded bit field. Instead of allocating separate bits for each parameter, the invention uses a unified encoding scheme where the joint encoded value simultaneously represents both the HARQ process number and the new data indicator state, thereby reducing overall bit consumption while maintaining independent decodability through defined mapping relationships.
Solution Approach 2:
The joint encoded bit field serves multiple functions simultaneously: it encodes the HARQ process number, indicates whether it is new data or retransmission, and provides a unified representation that can be flexibly interpreted. This multi-functional encoding approach allows the same bit field to convey multiple pieces of information that would traditionally require separate encoding resources.
2Adaptability or versatility
If more bits are allocated for downlink control information, then more information can be transmitted, but the scheduling flexibility decreases and the overhead increases
Solution Approach 1:
By combining the encoding of HARQ process number and new data indicator into a single joint encoded field, the patent reduces the total number of bits required in downlink control information. This consolidation maintains full scheduling flexibility because both parameters can still be independently determined from the joint encoding, allowing the system to adapt to different scheduling scenarios without being constrained by increased bit allocation.
3Quantity of substance
If joint encoding is used for first information and second information, then the number of bits is reduced and overhead decreases, but the encoding and decoding complexity increases
Solution Approach 1:
The patent applies joint encoding that merges multiple information elements into a compact representation. The encoding complexity is managed through systematic mapping rules that define relationships between the joint encoded value and the original parameters (HARQ process number and new data indicator). This approach reduces bit consumption while keeping the complexity manageable through well-defined encoding/decoding algorithms.
4Productivity
If traditional separate encoding is used, then the encoding process is simpler and more straightforward, but the downlink control information overhead increases and system performance deteriorates in high traffic scenarios
Solution Approach 1:
The joint encoding mechanism merges multiple control information parameters into a compact form, directly reducing downlink control information overhead. This reduction in overhead increases the efficiency of resource utilization, allowing more resources to be allocated for actual data transmission rather than control signaling, thereby improving overall system productivity and performance in high traffic scenarios.
