Wireless Communication Capability Signaling for Multi-Network Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in scenarios where user equipment (UE) needs to communicate with multiple networks simultaneously, there is a challenge in coordinating between networks to minimize latency and mutual influence, especially when the UE has limited capabilities to support simultaneous communications with two networks, and there is a need to avoid private information leakage and ensure efficient resource utilization.
Innovation Solution
A method where a first message is transmitted to indicate the capability of being in communication with a first network or a network other than the first network, with the message's transmission timing determined by conditions such as the establishment of an RRC connection, capability information transmission, and the inclusion of communication with the second network, allowing for coordinated communication without suspending the current network connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the UE communicates with multiple networks simultaneously, then the communication versatility is improved, but the coordination complexity and mutual influence between networks increase
Solution Approach 1:
The patent introduces a coordination mechanism where the network side acts as an intermediary to manage the UE's communication with multiple networks. The network receives capability information from the UE, determines appropriate communication configurations, and coordinates resource allocation to avoid mutual influence between different networks, thereby reducing coordination complexity while maintaining versatility
Solution Approach 2:
The patent implements preliminary action by having the UE transmit capability information to the network before actual communication begins. This allows the network to pre-determine the communication configuration and resource allocation strategy, avoiding real-time coordination conflicts and reducing the complexity of managing simultaneous multi-network communications
2Device complexity
If the UE uses limited hardware capabilities for multi-network communication, then the device complexity is reduced, but the communication quality and throughput are compromised
Solution Approach 1:
The patent applies partial action by having the UE transmit only the necessary capability information to the network rather than providing complete hardware specifications. This partial information transmission reduces the data processing burden on the UE while still enabling the network to make appropriate communication quality and throughput optimizations based on the essential capabilities
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting communication parameters such as bandwidth, modulation schemes, and resource allocation based on the capability information received from the UE. This allows the system to optimize throughput and communication quality by adapting parameters to the actual hardware capabilities and network conditions rather than relying on fixed configurations
3Object-affected harmful factors
If the network coordinates communication with multiple networks, then the mutual influence is reduced, but the latency and coordination time increase
Solution Approach 1:
The patent implements preliminary action by having the UE transmit capability information to the network before communication begins, allowing the network to pre-determine coordination strategies and resource allocation. This eliminates the need for real-time coordination during actual communication, significantly reducing coordination latency while maintaining effective mutual influence management
Solution Approach 2:
The patent applies self-service by having the UE autonomously determine and transmit its own capability information to the network. This self-provided information enables the network to independently make coordination decisions without requiring active participation or real-time feedback from the UE during communication, thereby reducing coordination latency while maintaining effective mutual influence management
4Reliability
If the UE transmits capability information to the network, then the communication coordination is improved, but the information transmission overhead increases
Solution Approach 1:
The patent extracts only the essential capability information from the UE's full hardware specification and transmits only these critical parameters to the network. By extracting and transmitting only the necessary capability data rather than complete hardware details, the system reduces information transmission overhead while maintaining sufficient information for reliable communication coordination

AI summary
The present application discloses a method and a device for wireless communications, including transmitting a first message; the first message being used to indicate at least one of a capability of being in communication with a first network or a capability of being in communication with a network other than the first network; the first message being for the first network; and being in communication with a second network; where whether the first message is transmitted before the action of being in communication with the second network or is transmitted along with the action of being in communication with the second network is related to whether any condition in a first condition set is satisfied. By transmitting the first message, this application helps to optimize the network, improve the reliability of communication, and avoid communication interruption.
