ENHANCED DYNAMIC SPECTRUM SHARING (DSS) IN CELL GROUPS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17765478 titled 'ENHANCED DYNAMIC SPECTRUM SHARING (DSS) IN CELL GROUPS

Simplified Explanation

The abstract describes techniques for dynamic spectrum sharing using a special scheduling cell (sSCell) in a cellular network.

  • The sSCell can schedule primary cells of master cell groups (MCG) or secondary cell groups (SCG).
  • The sSCell can be activated/deactivated, enter/exit dormancy, and perform radio link monitoring, beam failure recovery, and cell grouping.
  • Configuring UE-specific search spaces for DSS enhancement is included in the techniques.

---

      1. Potential Applications
  • Enhanced spectrum utilization in cellular networks.
  • Improved network efficiency and capacity through dynamic spectrum sharing.
      1. Problems Solved
  • Inefficient spectrum allocation in cellular networks.
  • Limited spectrum availability for increasing data demands.
      1. Benefits
  • Increased network capacity and efficiency.
  • Enhanced user experience with better spectrum utilization.
  • Improved overall network performance.


Original Abstract Submitted

Techniques described herein may include a special scheduling cell (sSCell) provided for dynamic spectrum sharing (DSS). The sSCell may schedule a primary cell of a master cell group (MCG) or a primary cell of a secondary cell group (SCG). The primary cell may be referred to as a special cell or SpCell. The sSCell may be activated and/or deactivated, enter in or exit from a state of dormancy, and radio link monitoring (RLM), beam failure recovery (BFR), and cell grouping parameters may be provided. Techniques described herein include configuring a UE-specific search space (USS) with non-fallback downlink control information (DCI), USS with fallback DCI, and overall search space for DSS enhancement.
