5G expansion into new use cases & verticals
Reliability from spatial diversity
Spatial diversity can overcome radio shadowing
in challenging radio environments
Key technology to provide ultra reliability for
challenging industrial IoT applications
Capacity from spatial multiplexing
Allows multiple transmissions at the same time to
multiple location without interfering
Can also be used to by multiple operators to share
spectrum more efficiently
8
Theoretical tradeoff between multiplexing and diversity
Multiple transmit and receive antennas with uncorrelated signal paths create spatial dimensions
1. L. Zheng and D. N. C. Tse, “Diversity and multiplexing: A fundamental tradeoff in multiple antenna channels,” IEEE Trans. Inform. Theory, vol. 49, May 2003.

Using spatial dimensions
to multiplex multiple data
streams increases capacity
Using spatial dimensions
for diversity reduces the
error rate
There is a tradeoff between
spatial multiplexing gain
and spatial diversity gain1

Exploiting spatial domain—from LTE MIMO to 5G CoMP
1) Multiple-input multiple-output (MIMO); 2) Coordinated Multi-Point (CoMP)
2 Gbps peak-rates with 4x4
MIMO1, carrier aggregation and
higher order modulation
Example: 2 or 4 antennas for
transmit and receive
Multi-user MIMO and 3D
beamforming for better capacity
and cell edge performance,
Example: 128 or 256 antenna
elements for macro deployments
Leveraging CoMP2 diversity and
multiplexing to extend 5G to
new use cases and verticals
Example: Multiple small-cells
with 4 antennas
LTE MIMO 5G Massive MIMO 5G CoMP
10
CoMP is an extension of MIMO
Massive MIMO
Utilizes a large number of antennas to create
multiple spatial dimension from multi-path propagation
to increase capacity and coverage and cell edge.
Example: Macro deployment
Utilizes a large number of distributed antennas
to create multiple spatial dimensions for increased
capacity and/or spatial diversity for reliability
Example: Small-cell deployment
CoMP aka Distributed MIMO
CoMP server

5G CoMP—different flavors
1) For example maximize the minimum signal to noise plus interference ratio; 2) This is referring to downlink. For uplink Joint Reception (JR) can be used.
Coord. Sched./Beamforming
• Data via one base station
• Coordinated beamforming between
base stations to improve overall
signal quality1
• Coordinated scheduling to
maximize resource utilization

• Data via multiple base stations2
• Multiple base stations transmit
same data with beamforming
• Coherent JT enables nulling;
