LTE TDD Channel Number Ranges
The carrier frequency in the uplink and downlink is designated by the E-UTRA Absolute Radio
Frequency Channel Number (EARFCN) in the range 0 – 65535. The relation between EARFCN and the
carrier frequency in MHz for the downlink is given by the following equation, where F
DL_low
and
N
Offs-DL
are given in table 5.4.4–1 and N
DL
is the downlink EARFCN.
F
DL
= F
DL_low
+ 0.1(N
DL
– N
Offs-DL
)
The relation between EARFCN and the carrier frequency in MHz for the uplink is given by the following
equation where F
UL_low
and N
Offs-UL
are given in table 5.4.4–1 and N
UL
is the uplink EARFCN.

Note: The channel numbers that designate carrier frequencies so close to the operating band edges that the carrier
extends beyond the operating band edge shall not be used. This implies that the first 7, 15, 25, 50, 75 and 100
channel numbers at the lower operating band edge and the last 6, 14, 24, 49, 74 and 99 channel numbers at the
upper operating band edge shall not be used for channel bandwidths of 1.4, 3, 5, 10, 15 and 20 MHz respectively.
