Innovation Solution
A method for processing UE capability information involves reporting and configuring capabilities related to the SCG deactivated state, including support for various operations and transitions, such as CSI-RS measurement, RRM, RLM, beam management, SRS transmission, and uplink timing advance, to enable efficient SCG suspension and activation based on UE capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If SCG deactivated state is introduced to save power consumption, then energy efficiency is improved, but UE capability clarity and network configuration accuracy deteriorate
Solution Approach 1:
The patent applies preliminary action by having the UE report capability information about SCG deactivated state support before the network configures SCG deactivation. The network side device obtains this capability information in advance through capability negotiation procedures, ensuring it has accurate knowledge of UE capabilities before implementing SCG deactivation to save power. This prevents configuration errors and ensures proper functionality while maintaining energy efficiency.
2Speed
If network side device configures SCG deactivated state without accurate UE capability information, then configuration speed is improved, but configuration accuracy and reliability deteriorate
Solution Approach 1:
The patent implements feedback by establishing a capability negotiation mechanism where the UE reports its SCG deactivated state capability information to the network side device. The network side device uses this feedback information to accurately determine whether to configure SCG deactivation and how to configure it, ensuring both speed and accuracy of configuration. The feedback loop ensures the network has up-to-date capability information for reliable configuration decisions.
3Reliability
If UE reports detailed capability information to network side device, then configuration accuracy is improved, but information processing complexity increases
Solution Approach 1:
The patent applies the extraction principle by identifying and reporting only the specific capability information related to SCG deactivated state support. Rather than requiring the UE to report all possible capability details, the patent extracts and transmits only the relevant capability parameters needed for SCG deactivation configuration. This reduces information processing complexity while maintaining configuration accuracy for SCG deactivated state functionality.
Data Source
AI summary
Provided are a UE capability information processing method and apparatus, a device, and a storage medium. The method comprising: reporting first capability information to a network side device; the first capability information being UE capability information associated with a SCG deactivate state (101); receiving, from the network-side device, first configuration information for instructing a UE to perform a configuration associated with the SCG deactivate state (102); and performing the configuration associated with the SCG deactivate state (103). By defining the UE capability associated to the SCG deactivate state in multiple connection scenarios, when the network side is performing an operation or configuration corresponding to the SCG deactivate state, on the basis of the corresponding UE capability, the network side may decide whether to perform or how to implement the corresponding operation or configuration, to ensure that when no data transmission exists on the SCG side, the SCG is suspended to conserve energy, and when needed, the SCG can be quickly activated to perform normal data transmission.
