COMMUNICATION APPARATUS, MASTER NODE, AND COMMUNICATION CONTROL METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18392436 titled 'COMMUNICATION APPARATUS, MASTER NODE, AND COMMUNICATION CONTROL METHOD
Simplified Explanation
The patent application describes a system where a user equipment (UE) is connected to a master node and a secondary node using a dual connectivity scheme. The UE includes a communicator to receive instructions to deactivate the secondary cell group and a controller to carry out the deactivation. Additionally, the controller can determine if a cell with beam failure is part of the deactivated secondary cell group and notify the master node accordingly.
- Explanation of the patent/innovation:
- User equipment connected to master and secondary nodes - Dual connectivity scheme utilized - Deactivation of secondary cell group instructed and carried out - Detection of beam failure in cells - Notification to master node of failure in secondary cell group
Potential applications of this technology: - Mobile communication networks - Internet of Things (IoT) devices - Smart city infrastructure
Problems solved by this technology: - Efficient management of cell groups - Improved network reliability - Enhanced user experience
Benefits of this technology: - Seamless connectivity for users - Better network performance - Reduced downtime for maintenance
Potential commercial applications of this technology: - Telecommunications companies - Network equipment manufacturers - IoT service providers
Possible prior art: - Similar dual connectivity schemes in mobile networks - Beam failure detection systems in communication networks
Unanswered questions: 1. How does the system handle handovers between primary and secondary cells? 2. What measures are in place to prevent unauthorized deactivation of cell groups?
Original Abstract Submitted
A user equipment is connected to a master node associated with a master cell group and connected to a secondary node associated with a secondary cell group by utilizing a dual connectivity scheme. The UE comprises: a communicator () configured to receive an RRC (radio resource control) message including information instructing deactivation of the secondary cell group; and a controller configured to deactivate the secondary cell group according to the information. The controller is configured to determine whether or not a cell in which beam failure is detected is a primary cell belonging to the deactivated secondary cell group, and the communicator () is configured to transmit an SCGFailureInformation message related to failure of the secondary cell group to the master node when the controller determines that the cell is the primary cell.
