Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently scheduling and managing the transmission of multiple transport blocks in uplink communications, particularly in 5G and NR networks, which can lead to inefficiencies and interference.
Innovation Solution
Implementing techniques for scheduling uplink transmissions of multiple transport blocks based on downlink control information (DCI) that indicates which blocks to transmit, using processors and communication managers in user equipment (UE) and network nodes to manage these transmissions effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple transport blocks are transmitted in uplink communications, then the data transmission capacity is improved, but the scheduling complexity and interference management difficulty increase
Solution Approach 1:
The patent segments the uplink transmission by dividing data into multiple transport blocks (TBs), each independently scheduled and transmitted. This allows the system to maintain high data transmission capacity while managing complexity through modular, independent handling of each TB rather than treating all data as a single unit.
Solution Approach 2:
The patent introduces a new dimension to scheduling by enabling multi-TB transmission within a single uplink slot, moving beyond traditional single-TB per slot scheduling. This dimensional expansion allows parallel transmission of multiple TBs with independent modulation and coding schemes, thereby increasing productivity without proportionally increasing scheduling complexity.
2Adaptability or versatility
If multiple transport blocks are scheduled with independent parameters, then the transmission flexibility is improved, but the control information overhead increases
Solution Approach 1:
The patent creates a universal uplink grant structure that can simultaneously schedule multiple transport blocks with different parameters. The DCI format is designed to be multi-functional, supporting independent modulation and coding schemes, different resource allocations, and varied transmission configurations for multiple TBs within a single grant, thereby maintaining flexibility without proportionally increasing overhead.
Solution Approach 2:
The patent merges the scheduling of multiple transport blocks into a single uplink grant and DCI message. Instead of transmitting separate control information for each TB, the system combines multiple TB scheduling parameters into one unified control structure, reducing the total control information overhead while preserving the ability to independently configure each transport block.
3Productivity
If efficient scheduling of multiple transport blocks is implemented, then the network performance is improved, but the processing requirements at UE and network node increase
Solution Approach 1:
The patent implements preliminary action by pre-configuring transport block parameters and scheduling decisions through downlink control information before actual transmission. The network node prepares and sends uplink grants with all necessary parameters for multiple TBs in advance, allowing the UE to process and prepare transmissions efficiently without requiring complex real-time decision-making during the transmission moment.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) that includes an uplink grant indicating information relating to multiple transport blocks for an uplink transmission, the information indicating which of the multiple transport blocks is to be transmitted. The UE may transmit one or more of the multiple transport blocks in accordance with the DCI. Numerous other aspects are described.
