Scheduling Restriction Enhancements for LTE and 5G NR Dynamic Spectrum Sharing - A simplified explanation of the abstract

This abstract first appeared for US patent application 18492158 titled 'Scheduling Restriction Enhancements for LTE and 5G NR Dynamic Spectrum Sharing

Simplified Explanation

Methods and devices are disclosed for a base station that acts as a primary cell and performs dual spectrum sharing (DSS) with two user equipment devices (UEs) over different connections. The first UE establishes a 5G NR connection with the primary cell and one or more secondary cells. One of the secondary cells is configured in the 5G NR connection to provide downlink control information to the UE for the primary cell, ensuring that there are no collisions between the primary cell and LTE control transmissions.

• The base station acts as a primary cell and performs dual spectrum sharing (DSS) with two UEs over different connections.
• The first UE establishes a 5G NR connection with the primary cell and one or more secondary cells.
• One of the secondary cells is configured to provide downlink control information to the first UE for the primary cell.
• This configuration avoids collisions between the primary cell and LTE control transmissions.

Potential applications of this technology:

• Improved spectrum utilization: By allowing a base station to simultaneously serve UEs over different connections, spectrum resources can be efficiently utilized.
• Seamless transition: The ability to establish a 5G NR connection with the primary cell and one or more secondary cells enables seamless handover and uninterrupted service for UEs.
• Enhanced network capacity: Dual spectrum sharing allows for increased network capacity by accommodating UEs on both 5G NR and LTE connections.

Problems solved by this technology:

• Collision avoidance: By configuring a secondary cell in the 5G NR connection to provide downlink control information, collisions between the primary cell and LTE control transmissions are avoided.
• Efficient resource allocation: Dual spectrum sharing enables efficient allocation of spectrum resources by allowing a base station to serve UEs over different connections simultaneously.

Benefits of this technology:

• Improved user experience: Seamless handover and uninterrupted service enhance the user experience for UEs.
• Enhanced network performance: Dual spectrum sharing increases network capacity and improves resource allocation, leading to better overall network performance.
• Efficient spectrum utilization: By utilizing spectrum resources more efficiently, this technology helps optimize the use of available spectrum.

Methods and devices for a base station acting as a primary cell to perform dual spectrum sharing (DSS) with a first user equipment device (UE) over a 5G NR connection and a second UE over an LTE connection. The first UE establishes the 5G NR connection with the primary cell and one or more secondary cells. One of the secondary cells is configured in the 5G NR connection to provide downlink control information to the UE for the primary cell, to avoid collisions by the primary cell with LTE control transmissions.
