Spectrum emission mask (SEM) measurement
This measurement provides a ratio of the transmitted power
in a 3.84 MHz RRC bandwidth to offset frequencies, which
are between 2.5 MHz and 12.5 MHz away from the UE carrier
frequency.

Adjacent channel leakage ratio (ACLR)
measurement
This measurement provides a ratio of the filtered mean trans-
mitted power to the filtered mean power in an adjacent channel.
Both the transmitted and the adjacent channel powers are
measured with a filter that has an RRC response with roll-off a =
0.22 and a bandwidth equal to the chip rate.
