(16)

BCH - Broadcast channels

Broadcast channels are point-to-multipoint unidirectional

(downlink) control channels from the fixed subsystem to

the mobile station:

Frequency Correction Channel (FCCH) allows an MS to

accurately tune to a Base Transceiver Station (BTS).

Synchronization Channel (SCH) provides TDMA

frame-oriented synchronization data to an MS.

Broadcast Control Channel (BCCH) intended to

broadcast a variety of information to MSs, including cues

necessary for the MS to register in the network.

(17)

CCCH - Common Control Channels

Common Control Channels (CCCHs) are

point-to-multipoint channels that are primarily intended to carry

signaling information for access handling functions. The

CCCHs include:

Paging Channel (PCH): downlink channel used to page

MSs.

Access Grant Channel (AGCH): downlink channel used to

assign an MS to a specific Dedicated Control Channel

(DCCH).

Cell Broadcast Channel (CBCH): downlink channel used

to broadcast miscellaneous short messages to the MSs.

Random Access Control Channel (RACH): uplink

(18)

DCCH - Dedicated Control Channels

Dedicated Control Channels are point-to-point, bi-directional control

channels. Two types of DCCHs are used:

Stand-alone Dedicated Control Channels (SDCCH) whose allocation

is not linked to the assignment of a traffic channel (TCH). They bear information about authentication, location updates, and assignment to traffic channels (TCHs).

Associated Control Channels are linked to the existence of a traffic channel (TCH).

– Fast Associated Control Channel (FACCH) or burst-stealing is a

control channel obtained by preemptive dynamic multiplexing on a TCH.

– Slow Associated Control Channel (SACCH), also known as a

(19)

TCH - Traffic Channels

TCH carries the voice data.

Two blocks of 57 bits contain voice data in the normal

burst.

One TCH is allocated for every active call.

Full rate traffic channel occupies one physical channel

(one TS on a carrier) and carries voice data at 13kbps

Two half rate (6.5kbps) TCHs can share one physical

(20)

GPRS

General packet radio service (GPRS) is a packet

oriented mobile data service available to users of the

2G cellular communication systems global system for

mobile communications (GSM), as well as in the 3G

systems. In the 2G systems, GPRS provides data rates

of 56-114 kbit/s.

EDGE: Enhanced Data rates for GSM

Evolution

In addition to GMSK, EDGE uses higher-order 8PSK (8 phase shift keying) for the upper five of its nine modulation and coding schemes. EDGE produces a 3-bit word for every change in carrier phase which effectively triples the gross data rate offered by GSM. EDGE, like GPRS, uses a rate adaptation algorithm that adapts the modulation and coding scheme (MCS) according to the quality of the radio channel, and thus the bit rate and robustness of data transmission.

EDGE can carry data speeds up to 236.8 kbit/s (with end-to-end latency of less than 150 ms) for 4 timeslots (theoretical maximum is 473.6 kbit/s for 8 timeslots) in packet mode. This means it can handle four times as much traffic as standard GPRS.

(29)

EDGE Modulation Schemes

EDGE is four times as efficient as GPRS. GPRS uses

four coding schemes (CS-1 to 4) while EDGE uses nine

Modulation and Coding Schemes (MCS-1 to 9).

(30)

Higher-order PSK

Any number of phases may

be used to construct a PSK

constellation but 8-PSK is

usually the highest order

PSK constellation deployed.

With more than 8 phases,

the error-rate becomes too

high and there are better,

though more complex,

modulations available such

as quadrature amplitude

modulation (QAM).

(31)

(32)

(33)

WCDMA-Spectrum Allocation

The frequency range 1920 – 1980 MHz and 2110 - 2170 MHz are available to operators as paired bands, these support UTRA

Frequency Division Duplex (FDD)

and are best suited to symmetric services such as telephony. A minimum frequency separation of 190 MHz has been specified

between transmit and receive frequencies.

In the lower band, 1900 - 1920 MHz and 2010 - 2025MHz are available as unpaired bands. These can support UTRA Time Division

Duplex (TDD), which is best suited

to asymmetrical services such as the internet.

HSPA+ or HSPA Evolved

Evolved High-Speed Packet Access (also known as: HSPA Evolution, HSPA+, I-HSPA or Internet HSPA) is a wireless broadband standard defined in 3GPP release 7.

HSPA+ enhances mobile broadband with data rates up to 42

Mbps in R8 while R7 enables up to 28 Mbps downlink data rates.

HSPA+ doubles the data capacity over HSPA and more than

doubles voice capacity over WCDMA, reducing the cost of

delivering voice or data services (more efficient voice over HSPA+ can also be used to free up data capacity).

HSPA+ multicarrier further enhances the broadband experience.

HSPA+ R8 doubles the data rates to all users and can significantly increase the bursty application capacity, e.g., Web browsing.

HSPA+ is the optimal solution for single and aggregated 5 MHz

(83)

(84)

Multiple Input Multiple Output (MIMO)

HSPA+ R7 supports 2x2 downlink MIMO that uses two

transmit antennas at the Node B to transmit orthogonal

(parallel) data streams to the two receive antennas at

the device. Using two antennas and additional signal

processing at the receiver and the transmitter, MIMO

can increase the system capacity and double user data

rates without using additional Node B power or

bandwidth.

MIMO M N MIMO propagation channel UE N o d e -B

(85)

High Order Modulation

HSPA supports 16QAM modulation on the downlink

and QPSK on the uplink. The data capacity

(bits/symbol) increases as we move from QPSK to

16QAM and 64QAM.

HSPA+ R7 introduces 64QAM on the downlink, which

increases the data rates by 50% for devices in good

signal conditions (high SNR). On the uplink, 16QAM

doubles data rates for devices that are not power

headroom limited.
