Candidate Waveforms

Some contenders:

– Cyclic Prefix based OFDM (CP-OFDM) – used in LTE

• Filter per full-band, uses cyclic prefix to separate symbols

• Not efficient for small packets

– Filter Bank Multicarrier (FBMC)

• Filter per subcarrier, reduced side lobes, no cyclic prefix

• Offset-QAM (OQAM) used to achieve orthogonality

– Universal Filtered Multicarrier (UFMC)

• Also known as universal filtered OFDM (UF-OFDM)

• Filter per sub-band, reduced side lobes, no cyclic prefix

• Claim to be efficient for both large and small packets

• QAM may be used for modulation

Increasing Frequencies: Challenge and Opportunity

– In words. For a given distance, as the frequency increases, the received

power will drop unless offset by an increase in some combination of transmit

power, transmit antenna gain, and receive antenna gain.

– The decrease in power as a function of frequency is caused by the decrease

in the antenna aperture.

IBM 94 GHz ArrayCan Tile for Larger Arrays

IBM Press Release, June 2013

The Good News:

• Higher frequency antennas elements are smaller

• Easier to assemble into electronically steered arrays

• Reduced interference. Energy goes where it’s needed

• Improve performance in dense crowds (5G goal)

• Higher frequencies wider bandwidths: faster (5G goal)

Challenges:

• Increased complexity with more elements

• Multiple antenna arrays required for spherical coverage

• Discovery and Tracking (mobile devices)

5G Applications at mmWave

– Signals in mmWave attenuates quickly. This

means smaller cell size i.e. Small cells

– Abundant mmWave contiguous spectrum =

very high overall system capacity

– “Great Service In a Crowd” is one of the

visions of 5G.

• mmWave small cells will enable ultra-dense

deployment in large cities and very crowded

locations, ex. stadiums, with high guaranteed

throughput

– mmWave enables very efficient frequency

reuse, allowing small cells to be placed

close enough to enable high capacity

– mmWave is also used for small cell

backhaul, line-of-sight (LOS)

Channel Models are Critical for 5G

Very little experience with radio-access technologies in the mmWave bands.

• Directional antennas required. New concept for mobile devices

• Propagation through materials. Signals will pass through walls, even at 60 GHz.

• Channel dynamics affects signal design and beam forming (algorithms and MAC design)

• Interference (sidelobe performance requirements, null steering)

For Massive MIMO the channel model affects:

• Choice of frequencies for the technology. 3, 6, 15, 28, 39, 60, 70GHz?

• Antenna design, number of antennas required

• Amplifier design (dynamic range, power, ACPR and other nonlinear behaviors such as AM/PM)

• Signal design (coherence time)

• Reciprocity calibration accuracy

• Total power requirements (especially for the BS)

Massive MIMO

– Description: Massive MIMO is Multiuser MIMO (MU-MIMO) where the

number of base station antennas is >> the number of users to improve

the SINR
