US 11,750,268 B2 · Systems, methods, and apparatus for inactive state beam failure recovery

Abstract

A method for beam failure recovery in a communication network may include detecting a beam failure based on a downlink transmission at a user equipment (UE) in an inactive state, and performing a beam failure recovery (BFR) procedure at the UE in the inactive state based on detecting the beam failure. The downlink transmission may include a reference signal. The reference signal may include a synchronization signal block, The reference signal may include a channel state information reference signal. Detecting the beam failure may include detecting the beam failure based on a beam failure measurement configuration. The method may further include receiving the beam failure measurement configuration at the UE. The UE may receive the beam failure measurement configuration based on a preconfigured uplink resources (PUR) response. The UE may receive the beam failure measurement configuration based on a system information block (SIB) transmission.
