name: EARFCN
full_form: E-UTRA Absolute Radio Frequency Channel Number
context: The carrier frequency in the uplink and downlink is designated by the E-UTRA Absolute Radio Frequency Channel Number (EARFCN) in the range 0 â 262143. The relation between EARFCN and the carrier frequency in MHz for the downlink is given by the following equation, where FDL_low and NOffs-DL are given in Table 5.7.3-1 and NDL is the downlink EARFCN. FDL = FDL_low + 0.1(NDL â NOffs-DL) The relation between EARFCN and the carrier frequency in MHz for the uplink is given by the following equation where FUL_low and NOffs-UL are given in Table 5.7.3-1 and NUL is the uplink EARFCN. FUL = FUL_low + 0.1(NUL â NOffs-UL) Table 5.7.3-1: E-UTRA channel numbers
description: The E-UTRA Absolute Radio Frequency Channel Number (EARFCN) is a parameter used to designate the carrier frequency in both uplink and downlink within the Evolved Universal Terrestrial Radio Access Network (E-UTRAN). It is a unique number assigned to each radio channel, ranging from 0 to 262143. The EARFCN value determines the exact frequency of the carrier wave for both transmission directions, utilizing specific equations that incorporate offset values and low-frequency references as outlined in Table 5.7.3-1.
explanation: EARFCN is classified as a Parameter because it serves as a numerical value used to configure and identify radio channels within the E-UTRAN, directly influencing the carrier frequencies for both uplink and downlink communications.
