METHOD FOR A TRANSMISSION/RECEPTION POINT (TRP) SPECIFIC BEAM FAILURE RECOVERY (BFR) FOR A SINGLE DOWNLINK CONTROL INFORMATION (DCI) MODE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17442059 titled 'METHOD FOR A TRANSMISSION/RECEPTION POINT (TRP) SPECIFIC BEAM FAILURE RECOVERY (BFR) FOR A SINGLE DOWNLINK CONTROL INFORMATION (DCI) MODE

Simplified Explanation

The abstract describes a patent application for a user equipment (UE) with a transceiver for wireless communication with multiple transmission/reception points (TRPs) and a processor for beam failure detection and recovery procedures.

• The UE is in a multi-TRP mode, enabling communication with multiple TRPs.
• The processor performs beam failure detection (BFD) procedures for each TRP and beam failure recovery (BFR) procedures based on the results of the BFD.
• Upon receiving a configuration message, the UE switches to a single-TRP mode.
• The processor updates the BFD and BFR procedures based on configuration settings.
• The updated procedures are then performed for the TRP based on the results of the updated BFD procedure.

Potential applications of this technology:

• Mobile devices with improved reliability in wireless communication.
• IoT devices with enhanced connectivity in multi-TRP environments.

Problems solved by this technology:

• Ensures seamless communication by detecting and recovering from beam failures.
• Optimizes communication performance in multi-TRP scenarios.

Benefits of this technology:

• Enhanced reliability and stability in wireless communication.
• Improved user experience with uninterrupted connectivity.
• Efficient utilization of multiple TRPs for better signal quality.

Original Abstract Submitted

Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a first transmission/reception point (TRP) and a second TRP and a processor communicatively coupled to the transceiver. The UE is in a multi-TRP mode. The processor is configured to perform a first beam failure detection (BFD) procedure for the first TRP and a second BFD procedure for the second TRP. The processor is further configured to perform a first beam failure recovery (BFR) procedure for the first TRP responsive to a result of the first BFD procedure and a second BFR for the second TRP responsive to a result of the second BFD procedure. The processor is further configured to receive a configuration message, a BFD configuration, and a BFR configuration. The UE switches to a single-TRP mode upon receiving the configuration message. The processor is further configured to update the first BFD procedure based on the BFD configuration and update the first BFR procedure based on the BFR configuration. Finally, the processor is configured to perform the updated first BFD procedure and the updated first BFR procedure for the first TRP responsive to a result of the updated first BFD procedure.
