CONTROL SIGNALING FOR SPECIAL CELL MOBILITY - A simplified explanation of the abstract

This abstract first appeared for US patent application 17876964 titled 'CONTROL SIGNALING FOR SPECIAL CELL MOBILITY

Simplified Explanation

Methods, systems, and devices for wireless communications are described in this patent application. The focus is on configuring a user equipment (UE) with a set of cells that support Layer 1 (L1) mobility, Layer 2 (L2) mobility, or both for special cells (SpCells). The network entity is responsible for transmitting a control signal to the UE to update an SpCell. The control signal includes a cell identifier (ID) indicating which cell to set as the SpCell and a transmission/reception point (TRP) ID indicating which TRP to set as the primary TRP (pTRP) for the SpCell. The UE then switches from its current SpCell to the cell indicated by the control signal and communicates with the network via the pTRP of the new SpCell.

  • The patent application describes a method for configuring a UE with a set of cells supporting L1 and/or L2 mobility for special cells.
  • The network entity transmits a control signal to the UE to update an SpCell.
  • The control signal includes a cell ID and a TRP ID to indicate the SpCell and its primary TRP.
  • The UE switches to the new SpCell indicated by the control signal and communicates with the network via the pTRP of the new SpCell.

Potential Applications:

  • This technology can be applied in wireless communication systems to enhance mobility management and improve network efficiency.
  • It can be used in cellular networks to optimize the selection and configuration of cells for specific user equipment.

Problems Solved:

  • The patent application addresses the need for efficient configuration and management of special cells in wireless communication systems.
  • It solves the problem of seamlessly switching between SpCells and ensuring proper communication with the network.

Benefits:

  • The technology allows for better control and optimization of cell selection and configuration for UEs.
  • It improves network efficiency by enabling smooth transitions between SpCells.
  • The method described in the patent application enhances the overall performance and reliability of wireless communication systems.


Original Abstract Submitted

Methods, systems, and devices for wireless communications are described. In some systems, a network entity may configure a user equipment (UE) with a set of cells supporting Layer 1 (L1) mobility, Layer 2 (L2) mobility, or both for special cells (SpCells). The network entity may transmit a control signal, such as a medium access control (MAC) control element (CE) or a downlink control information (DCI) message, to the UE to update an SpCell. The control signal may include a cell identifier (ID) indicating which cell to set as the SpCell. Additionally, the control signal may include a transmission/reception point (TRP) ID indicating which TRP to set as the primary TRP (pTRP) for the SpCell. In response to the control signal, the UE may switch from a current SpCell to the cell indicated by the control signal and may communicate with the network via the pTRP of the new SpCell.
