Solution Overview
Problem
The 5G communication system faces challenges in efficiently allocating and transmitting time-frequency resources to support forward compatibility, particularly in coexisting with future services, and effectively managing uplink control information transmission.
Innovation Solution
A method and apparatus for efficiently transmitting and receiving uplink control information by determining specific slots for transmission based on scheduling information received from a base station, allowing for flexible allocation of frequency-time resources and spatial resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If uplink control information is transmitted in all uplink slots, then reliability of control information delivery is improved, but resource wastage increases
Solution Approach 1:
The patent segments uplink control information transmission across multiple slots by determining specific transmission slots based on scheduling information. Instead of transmitting in all slots, the terminal divides the control information transmission task across selected slots, reducing redundant transmissions while ensuring delivery reliability through strategic slot selection.
2Productivity
If flexible slot allocation is implemented for uplink control information, then resource utilization efficiency is improved, but system complexity increases
Solution Approach 1:
The patent applies preliminary action by determining transmission slots in advance based on received scheduling information from the base station. The terminal uses the scheduling information to pre-determine which slots will be used for uplink control information transmission, avoiding complex real-time decisions and simplifying the overall system operation while maintaining flexibility.
3Productivity
If uplink control information and data are transmitted in the same slot, then transmission efficiency is improved, but interference between control and data increases
Solution Approach 1:
The patent segments control information and data transmissions by determining specific slots for control information separately from data transmission slots. This segmentation reduces overlap and interference between control and data channels while maintaining high transmission efficiency through coordinated slot selection based on scheduling information.
