full_form: Beam Failure Detection
context: be able to perform CSI-RS measurement without restrictions. - If the UE does not support simultaneousRxDataSSB-DiffNumerology, UE is required to measure one of but not both CSI-RS for BFD measurement and SSB. Longer measurement period for CSI-RS based BFD measurement is expected, and no requirements are defined. For FR1, when the CSI-RS for BFD measurement is in the same OFDM symbol as another CSI-RS for RLM, BFD, CBD or L1-RSRP measurement, UE shall be able to measure the CSI-RS for BFD measurement without any restriction. For FR2, when the CSI-RS for BFD measurement on one CC is in the same OFDM symbol as SSB for RLM, BFD or L1-RSRP measurement on the same CC or different CCs in the same band, or in the same symbol as SSB for CBD measurement on the same CC or different CCs in the same band when beam failure is detected, UE is required to measure one of but not both CSI-RS for BFD measurement and SSB. Longer measurement period for CSI-RS based BFD measurement is expected, and no
description: Beam Failure Detection (BFD) is a procedure in the 5G New Radio (NR) system that enables the detection of beam failure, which occurs when the User Equipment (UE) loses synchronization with the network due to beam misalignment or other reasons. The BFD procedure involves the measurement of Channel State Information-Reference Signals (CSI-RS) to detect beam failure.
explanation: The text describes a specific set of actions and measurements taken within the 5G NR system to identify and address beam failures. This clearly defines BFD as a defined procedure.
