HANDOVER IN DUAL CONNECTIVITY TO A PRIMARY BASE STATION AND A SECONDARY BASE STATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17441248 titled 'HANDOVER IN DUAL CONNECTIVITY TO A PRIMARY BASE STATION AND A SECONDARY BASE STATION

Simplified Explanation

The patent application is about apparatuses and methods for implementing techniques for a user equipment (UE) that has dual connectivity. The UE can communicate with a first primary base station in a first primary cell (PCell) and a second primary base station in a second PCell. The UE has dual connectivity in the second PCell using a first wireless carrier to communicate with the second primary base station and a second wireless carrier to communicate with a secondary base station in a primary secondary cell (PSCell). The UE receives a message from the first primary base station to perform a handover procedure. The UE performs the handover procedure according to the received message and also performs an addition procedure for the secondary base station in parallel with the handover procedure. The start time of the addition procedure can be before the end time of the handover procedure.

• The patent application describes apparatuses and methods for implementing dual connectivity in a user equipment (UE).
• The UE can communicate with two primary base stations in different primary cells.
• The UE uses different wireless carriers to communicate with the primary and secondary base stations.
• The UE receives a message from the first primary base station to perform a handover procedure.
• The UE performs the handover procedure according to the received message.
• The UE also performs an addition procedure for the secondary base station in parallel with the handover procedure.
• The start time of the addition procedure can be before the end time of the handover procedure.

Potential applications of this technology:

• Improved connectivity and seamless handover for user equipment in wireless communication networks.
• Enhanced performance and reliability of dual connectivity in user equipment.
• Efficient utilization of multiple base stations for improved network coverage and capacity.

Problems solved by this technology:

• Handover procedures can be complex and time-consuming, leading to interruptions in communication.
• Dual connectivity in user equipment can be challenging to implement and manage.
• Coordinating handover and addition procedures in parallel can improve the efficiency and effectiveness of the network.

Benefits of this technology:

• Seamless handover and improved connectivity for user equipment.
• Enhanced network performance and reliability.
• Efficient utilization of multiple base stations for better coverage and capacity.

Original Abstract Submitted

Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for a user equipment (UE) having dual connectivity. The UE can communicate with a first primary base station in a first primary cell (PCell) and a second primary base station in a second PCell. The UE has dual connectivity in the second PCell using a first wireless carrier to communicate with the second primary base station and a second wireless carrier to communicate with a secondary base station in a primary secondary cell (PSCell). The UE receives a message from the first primary base station to perform a handover procedure. The UE performs the handover procedure according to the received message, and further perform an addition procedure for the secondary base station in parallel with the handover procedure. A start time of the addition procedure can be before an end time of the handover procedure.
