Definition
3GPP
3rd Generation Partnership Project, responsible for LTE
ABS
Almost Blank Subframe
ACS
Adjacent Channel Selectivity is a measurement of a receiver's
ability to process a desired signal while rejecting a strong signal
in an adjacent frequency channel. ACS is defined as the ratio of
the receiver filter attenuation on the assigned channel frequency
to the receiver filter attenuation on the adjacent channel
frequency.
AWGN
Additive White Gaussian Noise is a channel model in which the
only impairment to communication is a linear addition of white
noise with a constant spectral density and a Gaussian distribution
of amplitude.
BER
Bit Error Rate
CN
Core Network
CP
Cyclic Prefix
CTC
Convolution Turbo Code is a high-performance forward error
correction (FEC) code
dB
Decibel. A logarithmic unit used to describe a ratio (such as
power ratio in radio telecommunications)
dBm
An abbreviation for the power ratio in decibels (dB) of the
measured power referenced to one milliwatt (mW). It is used as a
convenient measure of absolute power because of its capability
to express both very large and very small values in a short form
eNodeB
Evolved Node B, is the element in E-UTRAN of LTE
ESP
Encapsulating Security Payloads (ESP) provide confidentiality,
data-origin authentication, connectionless integrity, an anti-replay
service (a form of partial sequence integrity), and limited traffic-
flow confidentiality
E-UTRAN
Evolved UMTS Terrestrial Radio Access Network, is the air
interface of 3GPP's Long Term Evolution
EVM/RCE
The Error Vector Magnitude or EVM (sometimes also called
Receive Constellation Error or RCE) is a measure used to
quantify the performance of a digital radio transmitter or receiver.
It is measured in dB or percentage (%) – the lower the better
FDD
Frequency-Division Duplexing. A transceiver mode where the
transmitter and receiver operate at different carrier frequencies
GNSS
Global Navigation Satellite System is a term used to describe a
satellite navigation system with global coverage. There are
currently two fully operational GNSSs – the US GPS and the
Russian GLONASS.
GTP-U
GPRS Tunneling Protocol for User data is a relatively simple IP
based tunneling protocol which permits many tunnels between
each set of end points
HPBW
Half Power BandWidth is the angular separation in an antenna, in
which the magnitude of the radiation pattern decreases by 50%
(or -3 dB) from the peak of the main beam
ICS
In-channel selectivity is a measure of the receiver’s ability to
receive a wanted signal at its assigned Resource Block locations
in the presence of an interfering signal
IPSec
Internet Protocol Security is a protocol suite for securing Internet
Protocol (IP) communications by authenticating and encrypting
each IP packet of a communication session
