full_form: Guaranteed Flow Bit Rate
context: UE-AMBR, the IAB-donor can ensure that the MFBR is not exceeded by controlling the transmission rate of the downlink GBR bearer on the Uu interface between Donor DU and MT of 1st IAB-node. Therefore, intermediate IAB-nodes may not need to enforce the MFBR for DL GBR bearers. A similar mechanism can be applied for the uplink. The access IAB-node serving the UE ensures the UE-AMBR and MFBR are not exceeded on the Uu interface between the UE and its serving IAB-node. Thus, the UE-AMBR and MFBR also cannot be exceeded on upstream backhaul links. Consequently, intermediate IAB-nodes may not need to enforce uplink UE-AMBR nor MFBR for uplink GBR UE bearers. For GFBR, the UE's access IAB-node guarantees the GFBR by appropriately scheduling of the UE. In order to guarantee the GFBR on backhaul links, the intermediate IAB-nodes should also be informed of the GFBR of a UE's bearer. However, for the case where many UE-bearers are mapped to the same BH RLC channel, GFBR per UE bearer may not need
description: Guaranteed Flow Bit Rate (GFBR) is a parameter that ensures a minimum bit rate for a specific flow or bearer in the network. It guarantees a certain level of service quality for applications requiring consistent and predictable data transfer rates.
explanation: The text describes GFBR as a parameter used to ensure a minimum bit rate for specific flows, directly relating it to Quality of Service (QoS) principles and its function in maintaining service quality.
