BEAM FAILURE RECOVERY WITH UPLINK ANTENNA PANEL SELECTION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17904310 titled 'BEAM FAILURE RECOVERY WITH UPLINK ANTENNA PANEL SELECTION

Simplified Explanation

The patent application describes a user equipment (UE) that can recover from beam failures by selecting the appropriate uplink antenna panel. The UE detects a candidate beam, reports a beam failure recovery request to a gNB, switches to the corresponding antenna panel, and adjusts the configuration for uplink transmission.

• The UE determines the antenna panel for a candidate beam detection reference signal.
• Reports a beam failure recovery request to the gNB with antenna panel information.
• Switches from a second antenna panel to the first one after receiving a response from the gNB.
• Adjusts the configuration for uplink transmission accordingly.

After switching, the UE adjusts the configuration for uplink transmission to optimize performance.

Original Abstract Submitted

Disclosed is a user equipment (UE) configured to perform beam failure recovery with uplink antenna panel selection. In some embodiments, the UE determines a first UE antenna panel corresponding to a candidate beam detection (CBD) reference signal (RS); reports to a gNB a beam failure recovery request (BFRQ), the BFRQ including UE antenna panel information for the first UE antenna panel; and after receiving from the gNB a response to the BFRQ, changes from a second UE antenna panel to the first UE antenna panel and corresponding configuration for uplink transmission.
