METHODS AND DEVICES FOR BEAM FAILURE RECOVERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18195171 titled 'METHODS AND DEVICES FOR BEAM FAILURE RECOVERY

Simplified Explanation

This patent application describes a method for configuring Beam Failure Recovery (BFR) in a network device. BFR is a technique used in wireless communication systems to recover from beam failures, which occur when the connection between a terminal device and a secondary cell is lost.

  • The method involves receiving a beam failure report from a terminal device associated with a secondary cell.
  • The terminal device is then configured with various BFR options, including:
 - BFR with Physical Uplink Control Channel (PUCCH): This option uses a dedicated channel for transmitting control information to recover from beam failures.
 - BFR with Contention Free Random Access (CFRA): This option allows the terminal device to access the network without contention, reducing the chances of beam failures.
 - BFR with Contention Based Random Access (CBRA): This option allows the terminal device to access the network with contention, but still provides a mechanism for recovering from beam failures.
 - BFR without Physical Random Access Channel (PRACH) and PUCCH: This option eliminates the use of specific physical channels for random access and control information transmission, simplifying the BFR process.

Overall, this patent application presents a method for configuring BFR options in a network device to improve the recovery from beam failures in wireless communication systems.


Original Abstract Submitted

A method () in a network device for configuration of Beam Failure Recovery, BFR. The method () includes: receiving () from a terminal device a beam failure report associated with a Secondary Cell, SCell. The method () further includes: configuring () the terminal device with at least one of the following BFR options: BFR with Physical Uplink Control Channel, PUCCH, BFR with Contention Free Random Access, CFRA, BFR with Contention Based Random Access, CBRA, and BFR without Physical Random Access Channel, PRACH, and PUCCH.
