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
LED
Light Emitting Diode
LTE
Long Term Evolution
MAC
Medium Access Controller – responsible for several functions such Error
Correction, Packet (De)Multiplexing, etc…
MBSFN
Multicast-Broadcast Single Frequency Network is an LTE feature designed to
deliver services such as Mobile TV using the LTE infrastructure, and is expected
to be a competitor to DVB-H-based TV broadcast
MCS
Modulation and Coding Scheme
MME
Mobility Management Entity is the key control-node for the LTE access-network.
It is responsible, among other things for idle mode UE tracking and paging
procedure including retransmissions
MTBF
Mean Time Between Failures
OFDMA
Orthogonal Frequency-Division Multiple Access (OFDMA) is a multi-user
version of OFDM digital modulation scheme, used for eNodeB transmissions to
UEs
PDCP
Packet Data Convergence Protocol. A Sub-Layer in LTE responsible for IP
Header (De)Compression, etc…
PDU
Protocol Data Unit
PTP
Precision Time Protocol is used to synchronize clocks throughout a network. In
this document, PTP is referring to IEEE1588-2008 protocol
RB
Resource Block
RLC
Radio Link Control. A Sub-Layer in LTE responsible for Ack/Nack, error
correction, packet reordering, etc…
ROHS
Restriction Of Hazardous Substances
RRC
Radio Resource Control. A Sub-Layer in LTE responsible for Broadcast of
system information, paging, security functions, radio bearer control, etc…
RRM
Radio Resource Management is used to cover all functions that are related to
the assignment and sharing of radio resources among UEs
S-GW
Serving Gateway. A Core entity in the LTE EPC architecture responsible for
routing and forwarding user data packets, while also acting as the mobility
anchor for the user plane during inter-eNodeB handovers and as the anchor for
mobility between LTE and other 3GPP technologies
SBA
Switched Beam Antenna
SC-FDMA
Single-Carrier FDMA is a frequency-division multiple access scheme, dealing
with the assignment of multiple users to a shared communication resource.
Used in LTE for UE transmissions to the eNodeB
SCTP
Stream Control Transmission Protocol is a reliable transport layer protocol,
ensuring in-sequence transport of messages with congestion control like TCP
SDR
Software Defined Radio
