An Already Strong HSPA+ Evolution Path

Notes: R8 reaches 42 Mbps by combining 2x2 MIMO and HOM (64QAM) in 5 MHz, or by utilizing HOM (64QAM) and multicarrier in 10 MHz. R9 combines multicarrier and MIMO in 10 MHz to reach 84 Mbps peak rates. Uplink multicarrier doubles the uplink peak data rate to 23 Mbps in 10 MHz in R9. R10 expands multicarrier to 20 MHz to reach 168 Mbps. R11 expands multicarrier to 40MHz to reach 336 Mbps.

1900 MHz (Band II)

1800 MHz (band III)

1700 MHz (Band IV)

900 MHz (Band VIII)

850 MHz (Band V)

1Additional spectrum bands and band combinations continuously defined in 3GPP, e.g., support for band XI (1500MHz Japan) combinations has been added and band III (1800MHz) is being added, beyond 4X combinations expected to be added in R11 2With 4x multicarrier in R10 (and 8x in R11), carriers within the same band need to be adjacent and inter-band aggregation can span two different bands. 2For typical bursty applications and partial load.

Across bands R9 4x DL in R102

8x DL in R11

Wider Spectrum:

Higher Data Rates to All Users Provides More Capacity2

17

Smart Networks to Balance Uneven Load

1Different Data From Multiple Cells. Receive diversity with interference suppression (Type 3i receiver) required.

Heavy Load Medium Load Light Load

Typically uneven load that changes with time and location

Smart Network Technique:

Multipoint Transmission:1

F1: 5MHz F1: 5MHz

Today’s device can only be served by one cell—that could be heavily loaded

18

Improved Cell Edge

Network Load Balancing

By serving user from multiple cells

Utilizes unused capacity in neighboring cells Improves user experience in loaded cell

Multipoint Improves Overall Network Capacity EVOLVES MULTICARRIER—DATA FROM MULTIPLE CELLS/NODEBs

Note: Multipoint transmission is a 3GPP R11 candidate, a.k.a. SFDC. Receive diversity with interference suppression (type 3i receiver) required to reject other-cell interference.

F1: 5MHz F1: 5MHz F1: 5MHz F1: 5MHz

Improved Cell Edge

Network Load Balancing

19

The Next Leap In Performance—Small Cells

Adding small cells like Picocells, Femtocells, and Remote Radioheads

Note: Other improvements, such as higher order modulation will also help, but 64QAM is already commonly used. Other options are to use the available capacity better and reduce e.g. power or signaling overhead to get more usable capacity

How do we get more capacity?

Bring Network Closer to Users—Add Small Cells1

Optimizations Makes the Leap Even Bigger—Smart HetNets

Mitigate Interference E.g. Advanced Receivers

More Antennas e.g. 2x2 MIMO

Radio Link approaching theoretical limit

20

It’s not just about adding small cells — Optimization Further Improves Performance

Small cell range expansion—such as multipoint Femtocell interference management—UltraSON More interference coordination across nodes Leverage Multicarrier in HetNets Self-Organizing Networks (SON)1

Optimizations for Even Higher Capacity and Enhanced User Data Rates

Picocells Open Femtocells Remote Radio heads

Restricted access Femtocells

1Network SON techniques standardized already in R10, such as Minimization of Drive Tests (MDT) and Automatic Neighbor Relation (ANR) are part of 3GPP R10. Heterogeneous networks: macro network with added small cells like picocells and femtocells.

21

Example of HetNet Optimization: Multipoint Range Expansion

More overlapping coverage with small cell deployments —more use for multipoint

1Benefits HetNets (mix of macro networks with added small cells like picocells) due to more overlapping coverage with small cells.

Remote Radio heads Picocells Open Femtocells

More Users Benefit From Small Cell Enhanced Data Rates to All Users

Multipoint effectively expands the range of the small cell1
