METHOD AND APPARATUS FOR BEAM FAILURE DETECTION AND RECOVERY - A simplified explanation of the abstract
This abstract first appeared for US patent application 17935027 titled 'METHOD AND APPARATUS FOR BEAM FAILURE DETECTION AND RECOVERY
Simplified Explanation
The patent application describes methods and apparatuses for detecting beam failure in a wireless communication system. It specifically focuses on a method for operating a user equipment (UE) in this system. Here are the key points:
- The UE receives downlink control information (DCI) which includes a first transmission configuration indication (TCI) state.
- The UE also receives information about the type of the first TCI state.
- Based on the first TCI state and its type, the UE determines a first set of beam failure detection (BFD) reference signal (RS) resource configuration indexes.
- The type of the first TCI state can be a joint TCI state, a separate downlink (DL) TCI state, or a separate uplink (UL) TCI state.
- The BFD RS resource configuration indexes correspond to periodic CSI-RS resource configuration indexes.
Potential applications of this technology:
- Wireless communication systems that require efficient beam failure detection.
- User equipment (UE) devices in wireless networks.
- Communication networks that utilize downlink control information (DCI) for transmission configuration indication (TCI).
Problems solved by this technology:
- Efficient detection of beam failure in a wireless communication system.
- Accurate determination of beam failure based on TCI states and their types.
- Optimization of resource allocation for beam failure detection.
Benefits of this technology:
- Improved reliability and performance of wireless communication systems.
- Enhanced user experience by minimizing beam failure and improving signal quality.
- Efficient utilization of network resources for beam failure detection.
Original Abstract Submitted
Methods and apparatuses for beam failure detection in a wireless communication system. A method for operating a user equipment (UE) includes receiving downlink control information (DCI) including a first TCI field indicating a first transmission configuration indication (TCI) state; receiving information about a type of the first TCI state; and determining, based on the first TCI state and the type of the first TCI state, a first set of beam failure detection (BFD) reference signal (RS) resource configuration indexes. The type of the first TCI state is a joint TCI state indicated by a DLorJointTCIState parameter, a separate downlink (DL) TCI state indicated by a DLorJointTCIState parameter, or a separate UL TCI state indicated by a UL-TCIState parameter. The BFD RS resource configuration indexes correspond to periodic CSI-RS resource configuration indexes.
