Term
Expansion
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
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
TDD
Time-Division Duplexing. A transceiver mode where the transmitter and receiver
operate on the same carrier frequency
UE
User Equipment. The end user in LTE
WEEE
Waste Electrical and Electronic Equipment
