UMTS R5 Network Architecture

UMTS Elements Definition The Mobile Equipment (ME) is the radio terminal used

for radio communication over the Uu interface The UMTS Subscriber Identity Module (USIM) is a

smartcard that holds the subscriber identity performs authentication algorithms and stores authentication and encryption keys and some subscription information that is needed at the terminal

The Node B converts the data flow between the Iub and Uu interfaces It also participates in radio resource management

The Radio Network Controller (RNC) owns and controls the radio resources in its domain (the Node Bs connected to it)

Home Location Register (HLR) is a database located in the userrsquos home system that stores the master copy of the userrsquos service profile

DIT

DIT

Network Elements Definitions (2) Mobile Services Switching CentreVisitor Location

Register (MSCVLR) is the switch (MSC) and database (VLR) that serves the UE in its current location for Circuit-Switched (CS) services

Gateway MSC (GMSC) is the switch at the point where UMTS PLMN is connected to external CS networks All incoming and outgoing CS connections go through GMSC

Serving General Packet Radio Service (GPRS) Support Node (SGSN) functionality is similar to that of MSCVLR but is typically used for Packet-Switched (PS) services

Gateway GPRS Support Node (GGSN) functionality is close to that of GMSC but is in relation to PS services

DIT

WCDMA Network Architecture

DIT

WCDMA Network Architecture (2) WCDMA including the RAN (Radio Access Network) and the CN

(Core Network) The RAN is used to process all the radio-related functions The CN is used to process all voice calls and data connections within the

UMTS system and implements the function of external network switching and routing

Logically the CN is divided into the CS (Circuit Switched) Domain and the PS (Packet Switched) Domain

UTRAN CN and UE (User Equipment) together constitute the whole UMTS system

A RNS (Radio Network Sub-system) is composed of one RNC and one or several Node Bs

The Iu interface is used between RNC and CN while the Iub interface is adopted between RNC and Node B

DIT

WCDMA Network Architecture (3) Within UTRAN RNCs connect with one another

through the Iur interface The Iur interface can connect RNCs via the direct

physical connections among them or connect them through the transport network

RNC is used to allocate and control the radio resources of the connected or related Node B

Node B serves to convert the data flows between the Iub interface and the Uu interface and at the same time it also participates in part of radio resource management

HSPA+ Features in Release 7

DIT

MIMO and Higher Order Modulation Multiple Input Multiple Output (MIMO)

Release 7 HSPA+ introduced support for 2x2 MIMO on Downlink

Especially useful in low geometry (beam-forming) and high geometry (spatial multiplexing) regions in presence of multi-path

With MIMO peak data rate supported on Downlink is 28 Mbps Higher Order Modulation (HOM)

HOM schemes provide higher data rates especially for users in good cell geometry and users with Uplink power headroom

HOM complements MIMO by providing line of sight improvements

64 QAM in Downlink allows peak data rates of 21 Mbps 16 QAM in Uplink allows peak data rates of 11 Mbps

DIT

Higher Order Modulations in Release 7

DIT

Higher Order Modulation in Release 7 One of the features introduced in Release 7 is the use

of Higher Order Modulations (HOM) for both HSDPA and HSUPA to sustain higher peak data rate in areas with high SNR

In particular For the Downlink 64-QAM modulation is introduced

allowing 6 bitssymbol to be carried on the Physical Layer and increasing the theoretical peak data rate from 144 Mbps to 216 Mbps

For the Uplink 16-QAM modulation is introduced allowing 4 bitssymbol to be carried on the Physical Layer and increasing the theoretical peak data rate from 57 Mbps to 114 Mbps

DIT

HSPA+ Advantages Cost effective upgrade

HSPA is being widely deployed HSPA+ can leverage existing assets Cell Sites UTRAN and Core Network

Can be selectively deployed in areas with high demand for data and for voice Deployment of HSPA+ will provide an edge in terms of time

to deploy Selective deployment based upon needs can be easily

achieved Backward Compatibility

Backward compatible with existing UTRA No dedicated spectrum needed

R99 R5R6 HSPA and HSPA+ devices operate on the same network

UMTS Elements Definition The Mobile Equipment (ME) is the radio terminal used

for radio communication over the Uu interface The UMTS Subscriber Identity Module (USIM) is a

smartcard that holds the subscriber identity performs authentication algorithms and stores authentication and encryption keys and some subscription information that is needed at the terminal

The Node B converts the data flow between the Iub and Uu interfaces It also participates in radio resource management

The Radio Network Controller (RNC) owns and controls the radio resources in its domain (the Node Bs connected to it)

Home Location Register (HLR) is a database located in the userrsquos home system that stores the master copy of the userrsquos service profile

WCDMA Network Architecture

DIT

WCDMA Network Architecture (2) WCDMA including the RAN (Radio Access Network) and the CN

(Core Network) The RAN is used to process all the radio-related functions The CN is used to process all voice calls and data connections within the

UMTS system and implements the function of external network switching and routing

Logically the CN is divided into the CS (Circuit Switched) Domain and the PS (Packet Switched) Domain

UTRAN CN and UE (User Equipment) together constitute the whole UMTS system

A RNS (Radio Network Sub-system) is composed of one RNC and one or several Node Bs

The Iu interface is used between RNC and CN while the Iub interface is adopted between RNC and Node B

DIT

WCDMA Network Architecture (3) Within UTRAN RNCs connect with one another

through the Iur interface The Iur interface can connect RNCs via the direct

physical connections among them or connect them through the transport network

RNC is used to allocate and control the radio resources of the connected or related Node B

Node B serves to convert the data flows between the Iub interface and the Uu interface and at the same time it also participates in part of radio resource management

HSPA+ Features in Release 7

DIT

MIMO and Higher Order Modulation Multiple Input Multiple Output (MIMO)

Release 7 HSPA+ introduced support for 2x2 MIMO on Downlink

Especially useful in low geometry (beam-forming) and high geometry (spatial multiplexing) regions in presence of multi-path

With MIMO peak data rate supported on Downlink is 28 Mbps Higher Order Modulation (HOM)

HOM schemes provide higher data rates especially for users in good cell geometry and users with Uplink power headroom

HOM complements MIMO by providing line of sight improvements

64 QAM in Downlink allows peak data rates of 21 Mbps 16 QAM in Uplink allows peak data rates of 11 Mbps

DIT

Higher Order Modulations in Release 7

DIT

Higher Order Modulation in Release 7 One of the features introduced in Release 7 is the use

of Higher Order Modulations (HOM) for both HSDPA and HSUPA to sustain higher peak data rate in areas with high SNR

In particular For the Downlink 64-QAM modulation is introduced

allowing 6 bitssymbol to be carried on the Physical Layer and increasing the theoretical peak data rate from 144 Mbps to 216 Mbps

For the Uplink 16-QAM modulation is introduced allowing 4 bitssymbol to be carried on the Physical Layer and increasing the theoretical peak data rate from 57 Mbps to 114 Mbps

DIT

HSPA+ Advantages Cost effective upgrade

HSPA is being widely deployed HSPA+ can leverage existing assets Cell Sites UTRAN and Core Network

Can be selectively deployed in areas with high demand for data and for voice Deployment of HSPA+ will provide an edge in terms of time

to deploy Selective deployment based upon needs can be easily

achieved Backward Compatibility

Backward compatible with existing UTRA No dedicated spectrum needed

HSPA+ Features in Release 7

DIT

MIMO and Higher Order Modulation Multiple Input Multiple Output (MIMO)

Release 7 HSPA+ introduced support for 2x2 MIMO on Downlink

Especially useful in low geometry (beam-forming) and high geometry (spatial multiplexing) regions in presence of multi-path

With MIMO peak data rate supported on Downlink is 28 Mbps Higher Order Modulation (HOM)

HOM schemes provide higher data rates especially for users in good cell geometry and users with Uplink power headroom

HOM complements MIMO by providing line of sight improvements

64 QAM in Downlink allows peak data rates of 21 Mbps 16 QAM in Uplink allows peak data rates of 11 Mbps

DIT

Higher Order Modulations in Release 7

DIT

Higher Order Modulation in Release 7 One of the features introduced in Release 7 is the use

of Higher Order Modulations (HOM) for both HSDPA and HSUPA to sustain higher peak data rate in areas with high SNR

In particular For the Downlink 64-QAM modulation is introduced

allowing 6 bitssymbol to be carried on the Physical Layer and increasing the theoretical peak data rate from 144 Mbps to 216 Mbps

For the Uplink 16-QAM modulation is introduced allowing 4 bitssymbol to be carried on the Physical Layer and increasing the theoretical peak data rate from 57 Mbps to 114 Mbps

DIT

HSPA+ Advantages Cost effective upgrade

HSPA is being widely deployed HSPA+ can leverage existing assets Cell Sites UTRAN and Core Network

Can be selectively deployed in areas with high demand for data and for voice Deployment of HSPA+ will provide an edge in terms of time

to deploy Selective deployment based upon needs can be easily

achieved Backward Compatibility

UMTS Elements Definition The Mobile Equipment (ME) is the radio terminal used

for radio communication over the Uu interface The UMTS Subscriber Identity Module (USIM) is a

smartcard that holds the subscriber identity performs authentication algorithms and stores authentication and encryption keys and some subscription information that is needed at the terminal

The Node B converts the data flow between the Iub and Uu interfaces It also participates in radio resource management

The Radio Network Controller (RNC) owns and controls the radio resources in its domain (the Node Bs connected to it)

WCDMA Network Architecture (2) WCDMA including the RAN (Radio Access Network) and the CN

(Core Network) The RAN is used to process all the radio-related functions The CN is used to process all voice calls and data connections within the

UMTS system and implements the function of external network switching and routing

Logically the CN is divided into the CS (Circuit Switched) Domain and the PS (Packet Switched) Domain

UTRAN CN and UE (User Equipment) together constitute the whole UMTS system

A RNS (Radio Network Sub-system) is composed of one RNC and one or several Node Bs

The Iu interface is used between RNC and CN while the Iub interface is adopted between RNC and Node B

DIT

WCDMA Network Architecture (3) Within UTRAN RNCs connect with one another

through the Iur interface The Iur interface can connect RNCs via the direct

physical connections among them or connect them through the transport network

RNC is used to allocate and control the radio resources of the connected or related Node B

Node B serves to convert the data flows between the Iub interface and the Uu interface and at the same time it also participates in part of radio resource management

HSPA+ Features in Release 7

DIT

MIMO and Higher Order Modulation Multiple Input Multiple Output (MIMO)

Release 7 HSPA+ introduced support for 2x2 MIMO on Downlink

Especially useful in low geometry (beam-forming) and high geometry (spatial multiplexing) regions in presence of multi-path

With MIMO peak data rate supported on Downlink is 28 Mbps Higher Order Modulation (HOM)

HOM schemes provide higher data rates especially for users in good cell geometry and users with Uplink power headroom

HOM complements MIMO by providing line of sight improvements

64 QAM in Downlink allows peak data rates of 21 Mbps 16 QAM in Uplink allows peak data rates of 11 Mbps

DIT

Higher Order Modulations in Release 7

DIT

Higher Order Modulation in Release 7 One of the features introduced in Release 7 is the use

of Higher Order Modulations (HOM) for both HSDPA and HSUPA to sustain higher peak data rate in areas with high SNR

In particular For the Downlink 64-QAM modulation is introduced

allowing 6 bitssymbol to be carried on the Physical Layer and increasing the theoretical peak data rate from 144 Mbps to 216 Mbps

For the Uplink 16-QAM modulation is introduced allowing 4 bitssymbol to be carried on the Physical Layer and increasing the theoretical peak data rate from 57 Mbps to 114 Mbps

DIT

HSPA+ Advantages Cost effective upgrade

HSPA+ Features in Release 7

DIT

MIMO and Higher Order Modulation Multiple Input Multiple Output (MIMO)

Release 7 HSPA+ introduced support for 2x2 MIMO on Downlink

Especially useful in low geometry (beam-forming) and high geometry (spatial multiplexing) regions in presence of multi-path

With MIMO peak data rate supported on Downlink is 28 Mbps Higher Order Modulation (HOM)

HOM schemes provide higher data rates especially for users in good cell geometry and users with Uplink power headroom

HOM complements MIMO by providing line of sight improvements

64 QAM in Downlink allows peak data rates of 21 Mbps 16 QAM in Uplink allows peak data rates of 11 Mbps

DIT

Higher Order Modulations in Release 7

DIT

Higher Order Modulation in Release 7 One of the features introduced in Release 7 is the use

of Higher Order Modulations (HOM) for both HSDPA and HSUPA to sustain higher peak data rate in areas with high SNR

In particular For the Downlink 64-QAM modulation is introduced

allowing 6 bitssymbol to be carried on the Physical Layer and increasing the theoretical peak data rate from 144 Mbps to 216 Mbps

For the Uplink 16-QAM modulation is introduced allowing 4 bitssymbol to be carried on the Physical Layer and increasing the theoretical peak data rate from 57 Mbps to 114 Mbps

DIT

HSPA+ Advantages Cost effective upgrade

HSPA is being widely deployed HSPA+ can leverage existing assets Cell Sites UTRAN and Core Network

Can be selectively deployed in areas with high demand for data and for voice Deployment of HSPA+ will provide an edge in terms of time

WCDMA Network Architecture

DIT

WCDMA Network Architecture (2) WCDMA including the RAN (Radio Access Network) and the CN

(Core Network) The RAN is used to process all the radio-related functions The CN is used to process all voice calls and data connections within the

UMTS system and implements the function of external network switching and routing

Logically the CN is divided into the CS (Circuit Switched) Domain and the PS (Packet Switched) Domain

UTRAN CN and UE (User Equipment) together constitute the whole UMTS system

A RNS (Radio Network Sub-system) is composed of one RNC and one or several Node Bs

The Iu interface is used between RNC and CN while the Iub interface is adopted between RNC and Node B

DIT

WCDMA Network Architecture (3) Within UTRAN RNCs connect with one another

through the Iur interface The Iur interface can connect RNCs via the direct

physical connections among them or connect them through the transport network

RNC is used to allocate and control the radio resources of the connected or related Node B

Node B serves to convert the data flows between the Iub interface and the Uu interface and at the same time it also participates in part of radio resource management

HSPA+ Features in Release 7

DIT

MIMO and Higher Order Modulation Multiple Input Multiple Output (MIMO)

Release 7 HSPA+ introduced support for 2x2 MIMO on Downlink

Especially useful in low geometry (beam-forming) and high geometry (spatial multiplexing) regions in presence of multi-path

With MIMO peak data rate supported on Downlink is 28 Mbps Higher Order Modulation (HOM)

HOM schemes provide higher data rates especially for users in good cell geometry and users with Uplink power headroom

HOM complements MIMO by providing line of sight improvements

64 QAM in Downlink allows peak data rates of 21 Mbps 16 QAM in Uplink allows peak data rates of 11 Mbps

DIT

Higher Order Modulations in Release 7

DIT

Higher Order Modulation in Release 7 One of the features introduced in Release 7 is the use

of Higher Order Modulations (HOM) for both HSDPA and HSUPA to sustain higher peak data rate in areas with high SNR

In particular For the Downlink 64-QAM modulation is introduced

allowing 6 bitssymbol to be carried on the Physical Layer and increasing the theoretical peak data rate from 144 Mbps to 216 Mbps

For the Uplink 16-QAM modulation is introduced allowing 4 bitssymbol to be carried on the Physical Layer and increasing the theoretical peak data rate from 57 Mbps to 114 Mbps

DIT

HSPA+ Advantages Cost effective upgrade

HSPA is being widely deployed HSPA+ can leverage existing assets Cell Sites UTRAN and Core Network

Can be selectively deployed in areas with high demand for data and for voice Deployment of HSPA+ will provide an edge in terms of time

to deploy Selective deployment based upon needs can be easily

achieved Backward Compatibility

HSPA+ Features in Release 7

DIT

MIMO and Higher Order Modulation Multiple Input Multiple Output (MIMO)

Release 7 HSPA+ introduced support for 2x2 MIMO on Downlink

Especially useful in low geometry (beam-forming) and high geometry (spatial multiplexing) regions in presence of multi-path

With MIMO peak data rate supported on Downlink is 28 Mbps Higher Order Modulation (HOM)

HOM schemes provide higher data rates especially for users in good cell geometry and users with Uplink power headroom

HOM complements MIMO by providing line of sight improvements

64 QAM in Downlink allows peak data rates of 21 Mbps 16 QAM in Uplink allows peak data rates of 11 Mbps

DIT

Higher Order Modulations in Release 7

DIT

Higher Order Modulation in Release 7 One of the features introduced in Release 7 is the use

of Higher Order Modulations (HOM) for both HSDPA and HSUPA to sustain higher peak data rate in areas with high SNR

In particular For the Downlink 64-QAM modulation is introduced

allowing 6 bitssymbol to be carried on the Physical Layer and increasing the theoretical peak data rate from 144 Mbps to 216 Mbps

For the Uplink 16-QAM modulation is introduced allowing 4 bitssymbol to be carried on the Physical Layer and increasing the theoretical peak data rate from 57 Mbps to 114 Mbps

DIT

HSPA+ Advantages Cost effective upgrade

HSPA is being widely deployed HSPA+ can leverage existing assets Cell Sites UTRAN and Core Network

Can be selectively deployed in areas with high demand for data and for voice Deployment of HSPA+ will provide an edge in terms of time

to deploy Selective deployment based upon needs can be easily

achieved Backward Compatibility

Backward compatible with existing UTRA No dedicated spectrum needed

R99 R5R6 HSPA and HSPA+ devices operate on the same network

and power on a fast scheduling Maximum data rate of 576 Mbps

DIT

HSUPA Operation1 The UE sends a Transmission

Request to the Node B for getting resources

2 The Node B responds to the UE with a Grant Assignment thus allocating uplink band to the UE

3 The UE uses the grant to select appropriate transport format for the Data Transmission to the Node B

4 The Node B attempts to decode the received data and send ACKNAK to the UE In case of NAK data may be retransmitted

HSPA+ Features in Release 7

DIT

MIMO and Higher Order Modulation Multiple Input Multiple Output (MIMO)

Release 7 HSPA+ introduced support for 2x2 MIMO on Downlink

Especially useful in low geometry (beam-forming) and high geometry (spatial multiplexing) regions in presence of multi-path

With MIMO peak data rate supported on Downlink is 28 Mbps Higher Order Modulation (HOM)

HOM schemes provide higher data rates especially for users in good cell geometry and users with Uplink power headroom

HOM complements MIMO by providing line of sight improvements

64 QAM in Downlink allows peak data rates of 21 Mbps 16 QAM in Uplink allows peak data rates of 11 Mbps

DIT

Higher Order Modulations in Release 7

DIT

Higher Order Modulation in Release 7 One of the features introduced in Release 7 is the use

of Higher Order Modulations (HOM) for both HSDPA and HSUPA to sustain higher peak data rate in areas with high SNR

In particular For the Downlink 64-QAM modulation is introduced

allowing 6 bitssymbol to be carried on the Physical Layer and increasing the theoretical peak data rate from 144 Mbps to 216 Mbps

For the Uplink 16-QAM modulation is introduced allowing 4 bitssymbol to be carried on the Physical Layer and increasing the theoretical peak data rate from 57 Mbps to 114 Mbps

DIT

HSPA+ Advantages Cost effective upgrade

HSPA is being widely deployed HSPA+ can leverage existing assets Cell Sites UTRAN and Core Network

Can be selectively deployed in areas with high demand for data and for voice Deployment of HSPA+ will provide an edge in terms of time

to deploy Selective deployment based upon needs can be easily

achieved Backward Compatibility

Backward compatible with existing UTRA No dedicated spectrum needed

Goals For HSPA+ In Release 7 Enhancements in Release 7 will enable

Reduced latency Higher user throughput Higher system capacity Extended talk time Faster call setup

It is important to achieve these goals with minimal changes to software hardware and

network architecture ensuring backward compatibility

DIT

HSPA+ Features in Release 7

DIT

MIMO and Higher Order Modulation Multiple Input Multiple Output (MIMO)

Release 7 HSPA+ introduced support for 2x2 MIMO on Downlink

Especially useful in low geometry (beam-forming) and high geometry (spatial multiplexing) regions in presence of multi-path

With MIMO peak data rate supported on Downlink is 28 Mbps Higher Order Modulation (HOM)

HOM schemes provide higher data rates especially for users in good cell geometry and users with Uplink power headroom

HOM complements MIMO by providing line of sight improvements

64 QAM in Downlink allows peak data rates of 21 Mbps 16 QAM in Uplink allows peak data rates of 11 Mbps

DIT

Higher Order Modulations in Release 7

DIT

Higher Order Modulation in Release 7 One of the features introduced in Release 7 is the use

of Higher Order Modulations (HOM) for both HSDPA and HSUPA to sustain higher peak data rate in areas with high SNR

In particular For the Downlink 64-QAM modulation is introduced

allowing 6 bitssymbol to be carried on the Physical Layer and increasing the theoretical peak data rate from 144 Mbps to 216 Mbps

For the Uplink 16-QAM modulation is introduced allowing 4 bitssymbol to be carried on the Physical Layer and increasing the theoretical peak data rate from 57 Mbps to 114 Mbps

DIT

HSPA+ Advantages Cost effective upgrade

HSPA is being widely deployed HSPA+ can leverage existing assets Cell Sites UTRAN and Core Network

Can be selectively deployed in areas with high demand for data and for voice Deployment of HSPA+ will provide an edge in terms of time

to deploy Selective deployment based upon needs can be easily

achieved Backward Compatibility

Backward compatible with existing UTRA No dedicated spectrum needed

R99 R5R6 HSPA and HSPA+ devices operate on the same network
