TDM Transmission for Inter-RAT Dual Connectivity UE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18488644 titled 'TDM Transmission for Inter-RAT Dual Connectivity UE

Simplified Explanation

The patent application describes apparatuses, systems, and methods for a wireless device to simultaneously communicate with both a next generation network node and a legacy network node. The wireless device can establish a wireless link with a first cell operating in a first system bandwidth and another wireless link with a second cell operating in a second system bandwidth. The device can perform uplink activity for both the first and second radio access technologies (RATs) by time-division multiplexing (TDM) the uplink data for each RAT.

• The wireless device can establish two wireless links with different cells operating in different system bandwidths.
• The device can perform uplink activity for both the first and second RATs by TDM the uplink data for each RAT.
• The technology allows for substantially concurrent communications with both a next generation network node and a legacy network node.

Potential applications of this technology:

• Improved network connectivity: The ability to communicate with both next generation and legacy network nodes simultaneously can enhance network connectivity and provide a seamless transition between different network technologies.
• Enhanced data transfer: By utilizing multiple wireless links and TDM, the wireless device can achieve higher data transfer rates and improved overall performance.
• Compatibility with legacy systems: The technology allows wireless devices to continue communication with legacy network nodes while also taking advantage of the capabilities offered by next generation network nodes.

Problems solved by this technology:

• Seamless transition between networks: The ability to communicate with both next generation and legacy network nodes ensures uninterrupted connectivity and smooth handover between different network technologies.
• Efficient spectrum utilization: By utilizing TDM for uplink activity, the wireless device can efficiently utilize the available spectrum resources for both the first and second RATs.

Benefits of this technology:

• Improved user experience: The technology enables faster and more reliable network connections, resulting in a better user experience for wireless device users.
• Enhanced network capacity: By utilizing multiple wireless links and efficiently utilizing spectrum resources, the technology can increase network capacity and accommodate more simultaneous connections.
• Compatibility with existing infrastructure: The ability to communicate with both next generation and legacy network nodes ensures compatibility with existing network infrastructure, allowing for a smooth transition to new network technologies.

Original Abstract Submitted

Apparatuses, systems, and methods for a wireless device to perform substantially concurrent communications with a next generation network node and a legacy network node. The wireless device may be configured to stablish a first wireless link with a first cell according to a RAT, where the first cell operates in a first system bandwidth and establish a second wireless link with a second cell according to a RAT, where the second cell operates in a second system bandwidth. Further, the wireless device may be configured to perform uplink activity for both the first RAT and the second RAT by TDM uplink data for the first RAT and uplink data for the second RAT if uplink activity is scheduled according to both the first RAT and the second RAT.
