Base Station Uplink Data Decoding for Resource Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the LTE system, asynchronous validation of periodic resources by user equipment and base stations leads to erroneous data retransmissions and increased interruption time delays due to mismatched subframe transmissions of CQI and SRS information.
Innovation Solution
A method and system where the base station decodes uplink data or acknowledgement information according to the format of periodic indication information, determining the presence of such information before validating corresponding resources, thereby preventing erroneous retransmissions and reducing time delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base station performs CRC validation on periodic resources without first decoding the uplink data to determine periodic indication information, then the validation process can be executed, but asynchronous validation between base station and user equipment causes erroneous retransmissions and increased time delays
Solution Approach 1:
The base station first decodes the uplink data to obtain periodic indication information before performing CRC validation on the periodic resources. This preliminary action ensures that the base station knows whether periodic validation is needed, allowing it to synchronize its validation timing with the user equipment and avoid erroneous retransmissions while minimizing time delays.
2Productivity
If the base station asynchronously validates periodic resources without checking for periodic indication information in uplink data, then validation can be performed continuously, but data retransmission errors increase due to mismatched subframe transmissions
Solution Approach 1:
The base station uses the periodic indication information obtained from decoding uplink data as feedback to control its validation behavior. This feedback mechanism allows the base station to adjust its validation timing and scope based on actual system conditions, ensuring reliable data transmission while maintaining continuous validation capability.

AI summary
A method, a base station and a system for managing resources belong to the field of communication technologies. In an embodiment of the present invention, the base station decodes the uplink data or the acknowledgement information sent by the user equipment according to the format of the periodic indication information comprised in the uplink data or the acknowledgement information, determines that the uplink data or the acknowledgement information sent by the user equipment comprises the periodic indication information when the decoding is successful, and then validates the periodic resources corresponding to the periodic indication information comprised in the uplink data or the acknowledgement information. The technical solution of the present invention overcomes the problem in the prior art that data is erroneously retransmitted since the base station and the user equipment asynchronously validate the periodic resources corresponding to the periodic indication information, thereby reducing interruption time delay.
