TECHNIQUES FOR PERFORMING LAYER 1/LAYER 2 MOBILITY BASED ON MULTIPLE SECONDARY CELL GROUP CONFIGURATIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17948734 titled 'TECHNIQUES FOR PERFORMING LAYER 1/LAYER 2 MOBILITY BASED ON MULTIPLE SECONDARY CELL GROUP CONFIGURATIONS
Simplified Explanation
The patent application abstract describes a method for improving layer 1 (L1)/layer 2 (L2) mobility in certain scenarios by receiving an indication of mobility from a first cell to a second cell and transmitting parameters related to mobility failure, mobility history, or radio link failure (RLF) to assist the network node in subsequent L1/L2 mobility for the UE.
- Simplified Explanation:
- Method to enhance mobility between cells in a network by transmitting mobility indications and related parameters to assist in smooth transitions.
- Potential Applications:
- Mobile telecommunications networks - Internet of Things (IoT) devices - Autonomous vehicles
- Problems Solved:
- Improving handover performance between cells - Reducing mobility failures and radio link failures
- Benefits:
- Enhanced user experience with seamless mobility - Increased network efficiency and reliability
- Potential Commercial Applications:
- Telecommunications companies - IoT device manufacturers - Automotive industry for connected vehicles
- Possible Prior Art:
- Previous methods for handover optimization in cellular networks - Techniques for reducing radio link failures during mobility transitions
- Unanswered Questions:
- How does this method handle handovers between cells with different technologies (e.g., 4G to 5G)?
The abstract does not specify how the method handles handovers between cells with different technologies, which could be crucial for seamless mobility in heterogeneous networks.
- What impact does this method have on network latency during mobility transitions?
The abstract does not address the potential impact of this method on network latency during mobility transitions, which could be a critical factor for real-time applications such as voice calls or video streaming.
Original Abstract Submitted
Aspects described herein relate to improving layer 1 (L1)/layer 2 (L2) mobility in certain scenarios. In some aspects, an indication of mobility from a first cell in a candidate cell set configured for L1/L2 mobility to a second cell can be received, and one or more parameters related to mobility failure or mobility history or radio link failure (RLF) associated with the mobility to assist the network node in at least one of performing a subsequent L1/L2 mobility for the UE or avoiding RLF or mobility failure during the subsequent L1/L2 mobility can be transmitted. In other aspects, the indication of mobility can be transmitted and the one or more parameters can be received. In some aspects, a list of conditional primary secondary cell (PSCell) change (CPC) configurations can be communicated following a PCell switch.
