Master eNB Configures IDC Indication Messages for Dual Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Configuring user equipment (UE) initiated messages for dual connectivity in wireless communication systems is challenging, particularly in scenarios where in-device coexistence (IDC) indication messages need to be efficiently managed across different network points with non-ideal backhaul connections.
Innovation Solution
A method and apparatus where a master evolved NodeB (MeNB) configures a user equipment (UE) with an IDC indication message upon receiving a request from a secondary eNB (SeNB) in dual connectivity, utilizing a processor, memory, and transceiver to manage the configuration through dedicated signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dual connectivity is configured with separate eNBs (MeNB and SeNB), then system capacity and service availability are improved, but the complexity of configuring UE initiated messages increases
Solution Approach 1:
The patent merges the configuration function of UE initiated messages into a unified process handled by the MeNB. When the SeNB determines that an IDC indication message should be configured, it sends a request to the MeNB, which then configures the UE with the message. This combining of configuration operations at the MeNB reduces the complexity that would arise from each eNB independently configuring messages.
2Adaptability or versatility
If the SeNB independently configures the IDC indication message, then configuration flexibility is improved, but coordination overhead and signaling complexity increase
Solution Approach 1:
The MeNB acts as an intermediary between the SeNB and the UE for configuring IDC indication messages. The SeNB determines when configuration is needed and sends a request to the MeNB, which then performs the actual UE configuration. This intermediary approach maintains the flexibility for the SeNB to make configuration decisions while avoiding the complexity of direct SeNB-UE signaling for this specific message type.
3Manufacturing precision
If dedicated signaling is used to configure UE initiated messages, then configuration precision is improved, but message transmission time increases
Solution Approach 1:
The system performs preliminary configuration of the IDC indication message through dedicated signaling before actual IDC issues arise. By pre-configuring the UE with the capability to send IDC indication messages, the system ensures precise configuration is in place beforehand, reducing the need for time-consuming reconfiguration when IDC problems occur during operation.

AI summary
A method and apparatus for configuring a user equipment (UE) with an in-device coexistence (IDC) indication message in a wireless communication system is provided. A master evolved NodeB (MeNB) in dual connectivity receives a request to configure the IDC indication message from a secondary eNB (SeNB) in dual connectivity, and upon receiving the request, configures the UE with the IDC indication message.
