Base Station PDCCH Feedback for Faster 5G Resource Rescheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 5G network faces challenges with low speed and time delay in resource rescheduling due to the need for the network side to wait for the terminal to decode control information, receive and decode data information, and send a feedback signal before rescheduling resources.
Innovation Solution
A method involving sending control information over a PDCCH, starting to receive a feedback signal after decoding, and sending information in response to the feedback signal, with mechanisms for error detection and retransmission based on feedback signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network side waits for the terminal to decode control information, receive and decode data information, and send a feedback signal before rescheduling resources, then the terminal can ensure accurate decoding and reliable feedback, but the communication establishment procedure experiences large time delay and low efficiency
Solution Approach 1:
The terminal performs preliminary decoding of control information and sends feedback signals before the network side completes resource rescheduling. This allows the network side to prepare subsequent resources in advance based on received feedback, rather than waiting for the complete decode-feedback cycle to finish before acting.
Solution Approach 2:
The system transitions from a static waiting mode (network side idle until feedback received) to a dynamic mode where the network side can continuously monitor for feedback signals and immediately initiate resource rescheduling upon receipt, optimizing the timing of each communication phase.
2Reliability
If the network side waits for complete decoding and feedback before rescheduling, then communication reliability is maintained, but the resource utilization and communication speed are reduced
Solution Approach 1:
The terminal sends feedback signals in advance before resource rescheduling is complete, enabling the network side to prepare and allocate subsequent resources proactively. This preliminary feedback mechanism allows resource utilization to improve while maintaining reliability through early error detection.
Solution Approach 2:
The network side continuously monitors for feedback signals and maintains an ongoing rescheduling process rather than pausing for complete decode cycles. This continuous operation improves resource utilization by eliminating idle waiting periods while feedback signals ensure reliable communication through timely error detection.
3Adaptability or versatility
If the terminal sends feedback signals after decoding control information, then the network side can adjust resources based on actual decoding status, but the overall communication establishment speed is reduced
Solution Approach 1:
The terminal sends feedback signals in advance of the traditional wait-time, allowing the network side to begin resource adjustment preparations earlier. This preliminary feedback enables faster resource reallocation while still being based on actual decoding status, thus maintaining adaptability while improving speed.
Solution Approach 2:
The system skips the traditional sequential waiting period by having the terminal send feedback as soon as decoding is complete, allowing the network side to immediately proceed with resource rescheduling without unnecessary delays. This rushes through the communication establishment process while maintaining adaptability through status-based adjustments.

AI summary
The embodiments of the present disclosure provide a method for transmitting data, a base station, a terminal, a system, and a computer-readable storage medium. In the method for transmitting data, a base station sends control information to a terminal over a PDCCH, starts to receive a feedback signal which is sent by the terminal after decoding the control information, and sends information to the terminal after receiving the feedback signal.
