Modulation & Measurement Example
LTE UE Categories ■ ■
■
All categories support 20 MHz 64QAM mandatory in downlink, but not in uplink (except Class 5 & 8) 2x2 MIMO mandatory in other classes except Class 1
OFDM ■
■
■
Data is sent in parallel across the set of subcarriers , each subcarrier only transports a part of the whole transmission The throughput is the sum of the data rates of each individual (or used) subcarriers while the power is distributed to all used subcarriers FFT (Fast Fourier Transform) is used to create the orthogonal subcarriers. The number of subcarriers is determined by the FFT size (by the bandwidth)
OFDM (cont) OFDM stands for Orthogonal Frequency Division Multicarrier OFDM: Plain or Normal OFDM has no built-in multiple access
mechanism This suitable for broadcast systems like DVB-T/H which
transmit only broadcast and multicast signals and do not realy need an uplink feedback channel (although such systems exist too) Now we have to analyze how to handle access of multiple
users simultaneously to the system, each one using OFDM
OFDMA OFDMA stands for Orthogonal Frequency Divion Multiple Access Registered trademark by Runcom Ltd. The basic idea is to assign subcarrier to users based on their bit rate
services. With this approach it is quite easy to handle high and low bit rate users simultaneously in a single system. But still it is difficult to run highly variable traffic efficiently. The solution to this problem is to assign to a single users so called
resource blocks or scheduling blocks. Such block is simply a set of some subcarriers over some time. A single user can then use 1 or more Resource Blocks.

1 Resource Element = 1 sym x 1sc 1 Resource Block = 1TSL x 12 sc 1 RB Pair = 1 TTL x 12 sc
OFDM Key Parameters for FDD and TDD Modes
Data Rate Calculations 1. Maximum Channel Data Rate Max Data Rate= Number of Resource Blocks x 12 subscarriers x (14 symbols/1ms) = Number of Resource Blocks x 168 symbols/1ms 2. Impact of Channel Bandwidth: 5,10, 20 Mhz BW 5 MHZ -> 25 Resource Blocks = 25 x 168 symbols/1ms = 4,2 Msysmbols/s BW 10 MHZ -> 50 Resource Blocks = 50 x 168 symbols/1ms = 8,4 Msysmbols/s BW 20 MHZ -> 100 Resource Blocks = 100 x 168 symbols/1ms = 16,8 Msysmbols/s
3. Impact of Modulation: QPSK, 16QAM, 64QAM QPSK = 2 bits/symbol; 16QAM = 4 bits/symbol; 64QAM = 6 bits/symbol
QPSK = 16,8 x 2 bits/symbol =33,6 Mbps (20Mhz) 16QAM = 16,8 x 4 bits/symbol =67,2 Mbps 64QAM = 16,8 x 6 bits/symbol =100.8 Mbps *These bit rates are applicable to the bottom of the physical layer (coding rate & overheads have not been taken into account)

Overview HARQ Hybrid ARQ is a combination of • Forward error correction (channel coding) and • Automatic Repeat Request (retransmissions). HARQ performs retransmissions of MAC-hs PDUs from Node B to UE. HARQ processes • Typically 6 per UE (depends). • Stop-and-wait ARQ per process. • Processes operate in parallel.
Receiver performs combining of different transmission of same MAC-hs PDU. • Chase Combining: where exactly same bits are transmitted during each transmission for the packet • Incremental Redundancy: Channel encoder output is used so that 1st transmission has systematic bits and less or not parity bits and in case retransmission needed then parity bits (or more of them) form the second transmission.

Radio Resource Control (RRC) Packet Data Convergence Protocol (PDCP) Radio Link Control (RLC) Medium Access Control (MAC)
LTE Channels Architecture
•
•
•
Logical Channel - A Logical Channel transports control or data traffic between the RLC Sublayer and the MAC Sublayer. Logical Channels describe transmission reliability (RLC Acknowledged Mode, etc.). Transport Channel - A Transport Channel forwards control or data traffic between the MAC Sublayer and the Physical Layer. Transport Channels describe how the information will be formatted before being transmitted (coding, transport block size, etc.). Physical Channel - A Physical Channel provides the transmission media (resource elements) through which the information is actually transmitted

a) SameasLTErequirement b) Should be optimized or deployment in local area/microcell environments. Up to 20-100 MHz 3 times higher than that in LTE
Carrier Aggregation-Introduction The need for CA in LTE-Advanced arises from the requirement to support bandwidths larger than those currently supported in LTE (LTE Rel-8 Component Carriers / Band Numerology) while at the same time ensuring backward compatibility with LTE.
•
Higher bandwidth - higher data rates.
•
Potential to aggregate five 20MHz blocks for 100MHz.
•
In LTE Rel-10, both symmetric as well as asymmetric CA are supported.
•
Symmetric CA - number of DL and UL Component Carriers are the same.
•
Asymmetric CA - number and bandwidth of DL and UL Component Carriers are different.
Enhanced Multi-Antenna Transmission Techniques In LTE-A, the MIMO scheme has to be further improved in the area of spectrum
efficiency, average cell through put and cell edge performances. In LTE-A the antenna configurations of 8x8 in DL and 4x4 in UL are planned.
Downlink Direction
Uplink Uplink Direction
MIMO Tx & Rx Schemes LTE-A(8X4 MIMO)
Coordinated Multi-Point Transmission / Reception (CoMP) •
•
CoMP is considered by 3GPP as a tool to improve coverage, cell-edge throughput, and enable flexible resource provisioning. Applies to Intra eNodeB (across sectors), Inter eNode B (requires data exchange via X2), and Heterogeneous Network
Coordinated Multi-Point Transmission / Reception (CoMP) cont.. Joint Transmission/Joint Processing ■
When two, or more, TX-points, transmit on the same frequency in the same subframe it is called Joint Transmission. Radio frame, with 10 subframes
Both the green and the blue TXpoint transmits in each subframe
Data is transmitted at the same frequency at the same time from multiple TX point, here two TX-points transmit to one UE in the same radio resource,
Relaying
3GPP classification of Relay stations Type 1 Relay Station •
•
• •
A Type 1 relay effectively creates its own cell, i.e. transmits its own identity number (Cell ID) and own synchronization and reference signals. The UE receives scheduling information and HARQ feedback directly from and sends its own control channels to the relay station. From an UE perspective this Type1 relay station looks like a eNodeB. It is also required that LTE Release 8 terminals are supported by this Type 1 relay station. It has already been agreed to include Type 1relay stations into LTE-Advanced specifications.
3GPP classification of Relay stations cont.. Type 2 Relay Station •
•
•
Type 2 relay station will not have its own Cell ID and thus would not create any new cell(s). Consequently the UE will not be able to distinguish between transmitted signals form the eNodeB and the relay station In such a scenario it would be possible to transmit control information from the eNodeB and data via the relay station.
Heterogeneous Networks (HetNets) •
•
•
Small cells are primarily added to increase capacity in hot spots with high user demand and to fill in areas not covered by the macro network– both outdoors and indoors. They also improve network performance and service quality by offloading from the large macro-cells. The result is a heterogeneous network with large macro-cells in combination with small cells providing increased bitrates per unit area.
HeNB (Home eNB): It was introduced in LTE Release 9 . It is a low power eNB which is mainly used to provide indoor coverage, femtocells, for Closed Subscriber Groups (CSG), for example, in office premises. • •
