Wireless Capability Negotiation Timing Rules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the lack of clear agreement between terminal devices and network devices on the effective or expiry time of negotiated capabilities can lead to communication efficiency degradation, including increased bit error rates and unnecessary data retransmissions.
Innovation Solution
A method where terminal devices send a message to network devices for capability negotiation, with the negotiation rules determining the effect or expiry time of the capability, ensuring both devices have a consistent understanding of when the capability takes effect or expires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If capability negotiation is performed between terminal device and network device, then the network device can know the dynamic changes of terminal capability, but the communication efficiency degrades due to disagreement on effect time or expiry time of the capability
Solution Approach 1:
The patent applies preliminary action by pre-defining capability effect time and expiry time rules in the capability negotiation message. The terminal device and network device agree in advance on when the negotiated capability takes effect and when it expires, eliminating subsequent misunderstandings. This preliminary agreement on timing parameters prevents communication efficiency degradation while maintaining reliable capability understanding.
2Adaptability or versatility
If the terminal device dynamically changes capability based on hardware resource sharing, then the capability adapts to different communication card usage scenarios, but the bit error rate increases due to unclear capability effect time
Solution Approach 1:
The patent applies preliminary action by pre-defining capability effect time and expiry time rules in the capability negotiation message. The terminal device and network device agree in advance on when the negotiated capability takes effect and when it expires, eliminating subsequent misunderstandings. This preliminary agreement on timing parameters prevents communication efficiency degradation while maintaining reliable capability understanding.
Solution Approach 2:
The patent implements feedback by having the network device send back capability confirmation messages that include the agreed effect time and expiry time. This feedback loop ensures both terminal and network devices have consistent understanding of the capability validity period, preventing bit error rates from increasing due to timing mismatches while allowing dynamic capability changes.
3Device complexity
If no capability effect time agreement is made, then the negotiation process is simpler, but unnecessary data retransmission occurs due to capability understanding mismatch
Solution Approach 1:
The patent applies preliminary action by pre-defining capability effect time and expiry time rules in the capability negotiation message. The terminal device and network device agree in advance on when the negotiated capability takes effect and when it expires, eliminating subsequent misunderstandings. This preliminary agreement on timing parameters prevents communication efficiency degradation while maintaining reliable capability understanding.

AI summary
A method for wireless communication, a terminal device, and a network device are provided. The method includes the following. A terminal device sends a first message to a network device, where the first message is used for negotiation of a first capability of the terminal device, and the first capability is associated with a first rule. The terminal device determines an effect time or an expiry time of the first capability based on the first rule.
