UE Capability Reporting via Independent Message Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for reporting user terminal capability information are inflexible and impose high requirements on report delay and reliability due to the large size of the information, exceeding the capacity of current radio resource control messages.
Innovation Solution
The method involves sending multiple response messages from the user terminal to the access network device, each containing a subset of the user terminal capability information, allowing for separate encoding and decoding, and includes mechanisms for managing the transmission process to ensure efficient and reliable reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If capability information is divided into multiple segments for sending, then the information can be transmitted within message size limits, but the reporting process becomes inflexible and requires receiving all segments before decoding
Solution Approach 1:
The capability information is divided into multiple capability containers, each containing a subset of capability information. Each container can be independently encoded and decoded, allowing the network device to process received containers immediately without waiting for all segments to be received. This resolves the contradiction by enabling both large information transmission and operational flexibility.
2Loss of information
If all capability information is reported at once, then complete information is available, but the report delay increases and reliability requirements become higher
Solution Approach 1:
The capability information is pre-divided into multiple containers that can be transmitted in sequence. The network device can perform preliminary processing on each container as it arrives, rather than waiting for complete information. This reduces report delay while maintaining information completeness through progressive reception and processing.
3Quantity of substance
If capability information is segmented and requires receiving all segments before decoding, then message size constraints are satisfied, but reliability requirements increase
Solution Approach 1:
The capability information is segmented into independent containers, each with complete encoding information. This allows the network device to decode and process individual containers independently, reducing reliability requirements compared to receiving all segments before decoding. Each container can be processed with higher reliability independently.

AI summary
The present disclosure relates to methods and apparatuses for transmitting user equipment capability information. One example method includes after sending a first request message to a user terminal, receiving, by an access network device, a plurality of first response messages sent by the user terminal, where each of the first response messages includes a subset of a UE capability information set, and decoding, by the access network device, the first response message to obtain a UE capability.
