Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment with low data processing capability in MTC/NB-IoT scenarios faces challenges in efficiently processing transmission blocks due to insufficient processing time, leading to incomplete demodulation and increased power consumption from continuous blind detection.
Innovation Solution
Introducing a preset time interval between adjacent transmission blocks to allow sufficient processing time for user equipment, ensuring complete demodulation by spacing the blocks, which can be determined based on communication protocol, data processing capability, or signaled by the base station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If transmission blocks are continuously scheduled through one signaling, then the number of blind detections is reduced, but the user equipment lacks sufficient processing time for each transmission block
Solution Approach 1:
The patent segments the continuous transmission block scheduling into discrete time intervals. By introducing preset time intervals between adjacent transmission blocks, the system allows user equipment to process each block completely while still maintaining efficient scheduling. This segmentation resolves the contradiction by providing both sufficient processing time and reduced blind detection through structured timing.
Solution Approach 2:
The patent implements periodic action by establishing regular time intervals between transmission blocks. This periodic structure ensures that user equipment has adequate processing time between blocks while the base station can efficiently schedule multiple blocks in sequence. The periodic timing mechanism balances processing requirements with transmission efficiency.
2Reliability
If transmission blocks are spaced by preset time intervals, then user equipment has sufficient processing time, but the transmission efficiency may be reduced
Solution Approach 1:
The patent applies parameter changes by adjusting the time interval parameter between transmission blocks based on user equipment capabilities and channel conditions. By optimizing this parameter, the system achieves reliable demodulation while minimizing idle time, thus balancing reliability with transmission efficiency through parameter optimization.
3Reliability
If user equipment performs blind detection for each transmission block, then communication reliability is maintained, but power consumption increases
Solution Approach 1:
The patent implements preliminary action by having the base station provide advance information about transmission block scheduling through signaling. This allows user equipment to prepare for reception and processing in advance, reducing the need for continuous blind detection and lowering power consumption while maintaining communication reliability through pre-configured parameters.

AI summary
Embodiments of the present invention provide methods of processing transmission blocks, which are applied to user equipment. The method includes: receiving a scheduling signaling from a base station, where the scheduling signaling is configured to schedule a plurality of transmission blocks; and transmitting the plurality of transmission blocks to the base station and/or receiving the plurality of transmission blocks from the base station, where two adjacent transmission blocks of the plurality of transmission blocks are spaced by a preset time interval. According to the embodiments of the present invention, two adjacent transmission blocks of the transmission blocks are spaced by a preset time interval. Therefore, compared with the case that the transmission blocks are continuously scheduled in a related art, user equipment can take more time to process a resource corresponding to each of the transmission blocks, so as to ensure that the transmission blocks are transmitted and received well.
