Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in efficiently signaling control information to support higher data rates beyond 4th-Generation (4G) networks, such as long term evolution (LTE), particularly in pre-5th-Generation (5G) or 5G/NR systems, to meet the demands of advanced wireless communication requirements.
Innovation Solution
The implementation of efficient signaling mechanisms for control information in advanced communication systems, including techniques like beamforming, massive multiple-input multiple-output (MIMO), and advanced access technologies, to enhance data transmission and reception in 5G/NR networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If existing 4G communication systems are used, then system complexity is lower, but data rates cannot support higher requirements beyond 4G
Solution Approach 1:
The patent applies parameter changes by introducing new modulation and coding schemes, changing resource allocation parameters, and modifying transmission parameters to enable higher data rates in 5G/NR systems while managing the increased system complexity through standardized protocols
Solution Approach 2:
The patent implements dynamic resource allocation, adaptive modulation and coding, and flexible frame structures that allow the system to adjust parameters in real-time based on channel conditions, enabling high data rates while managing complexity through automation
2Productivity
If control information signaling is optimized for 5G/NR, then data transmission efficiency improves, but signaling complexity increases
Solution Approach 1:
The patent segments control information into different types (downlink control information, uplink control information) and uses separate channels (PDCCH for downlink, PUCCH for uplink) to transmit them, which organizes the signaling complexity and improves transmission efficiency by allowing parallel processing
Solution Approach 2:
The patent designs control information structures that can be universally applied across different 5G/NR scenarios, with flexible field configurations that can indicate different types of information (scheduling, resource allocation, power control) using the same basic signaling framework
3Power
If beamforming and massive MIMO are implemented, then capacity and data rates increase, but device and system complexity increases
Solution Approach 1:
The patent implements nested structures where beamforming operations are integrated within the MIMO framework, and control information for beam management is embedded within the existing physical downlink control channel structure, allowing complex functions to be organized in nested layers that manage complexity

AI summary
Method and apparatus are provided for decoding a downlink control information (DCI) format that schedules a physical uplink shared channel (PUSCH) transmission and includes a field indicating whether or not data information is multiplexed in the PUSCH and for transmitting the PUSCH with or without data information depending on the indication by the field.
