name: EARFCN
full_form: E-UTRA Absolute Radio Frequency Channel Number
context: Based on the self evaluation results presented through Section 5 to 8, NR RIT fulfils all technical performance requirements in the five test environments: Indoor Hotspot â eMBB, Dense Urban â eMBB, Rural â eMBB, Urban Macro â URLLC and Urban Macro â mMTC. LTE RIT fulfils the technical performance requirements in at least four test environments: Indoor Hotspot â eMBB, Dense Urban â eMBB, Rural â emBB, Urban Macro â mMTC. Both NR RIT and LTE RIT fulfils the spectrum requirement. NR RIT can support the frequency bands identified for IMT in the ITU Radio Regulations, as well as the higher frequency range/band(s) above 24.25 GHz. LTE RIT can support the frequency bands identified for IMT in the ITU Radio Regulations. Both NR RIT and LTE RIT fulfils service requirements. It is therefore concluded that - 3GPPâs 5G SRIT can meet IMT-2020 requirements. - 3GPPâs 5G NR RIT can meet IMT-2020 requirements
description: The E-UTRA Absolute Radio Frequency Channel Number (EARFCN) is a unique identifier used in LTE networks to identify a specific radio frequency channel. It plays a crucial role in configuring and aligning LTE channels within the NR carrier, ensuring co-existence with different channel rasters such as 100kHz, 15kHz, or 30kHz. The EARFCN coincides with the center of the DC subcarrier in LTE, allowing for subcarrier-level alignment between LTE and NR, but not at the PRB level due to the presence of the DC subcarrier.
explanation: The text describes EARFCN as a unique identifier used to specify radio frequency channels in LTE networks. It's used for configuring and aligning channels, indicating its function as a code or label for specific frequencies. This clearly classifies it as an 'Identifier'.
