5G New Radio introduces a new type of wireless backhaul known as
integrated access and backhaul that is of particular interest for dense
deployment of street-level radio nodes.
HENRIK RONKAINEN,
JONAS EDSTAM,
ANDERS ERICSSON,
CHRISTER ÖSTBERG
The combination of millimeter wave (mmWave)
spectrum – which is becoming available
globally for 5G – with other spectrum assets
below 6GHz results in high speeds and
capacities. The mmWave radio resources can
only provide limited coverage, though, which
makes it reasonable to expect a fairly low level
ofutilization.Asaresult,thereisanopportunity
to use an innovative type of wireless backhaul
in 5G – integrated access and backhaul (IAB)
– to densify networks with multi-band radio
sites at street level.
■ Transport networks play a vital role in RANs
by connecting all the pieces. The use of dark fiber
for 5G transport is of growing importance [1],
and wireless backhaul is an essential complement
for sites where fiber is either not available or too
costly. In fact, microwave backhaul has been
the dominant global backhaul media for over
two decades and will remain a highly attractive
complement to fiber for 5G transport [2].

IAB is defined to reuse existing 5G NR functions
and interfaces, as well as to minimize impact
on the core network. The architecture is scalable,
so that the number of backhaul hops is only
limited by network performance. From a transport
perspective, IAB provides generic IP connectivity
to enable an easy upgrade to fiber transport
when needed.

Physicallayeraspects
The IAB feature is intended to support out-of-
band and in-band backhauling, where the latter
means usage of the same carrier frequencies for
both the NR backhaul links and the access links.
In-band operation comes with a half-duplex
constraint, implying that the IAB-MT part of an
IAB node cannot receive while its collocated DU
is transmitting and vice versa to avoid intra-site
interference. A strict time-domain separation
is therefore required between transmission
and reception phases within each IAB node.

restrict the size of the IAB network topology,
where in-band operation (sharing spectrum for
both backhaul and access) is an essential reason
for these limitations. Larger IAB topologies might
also require complex control functions. But since
IAB is a complement to fiber, the size of most
IAB networks is expected to be small.

In order to properly assess IAB-specific

an IAB proof of concept (PoC) testbed in an
authentic environment. At the Ericsson site in
Stockholm we have set up a two-hop IAB
deployment using two-sector IAB nodes with
either 28GHz or 39GHz AAS radios with
100MHz bandwidth, as shown in Figure 4.

electrical engineering from
LinköpingUniversity,Sweden.
Christer Östberg
◆ is an expert in the physical
layer of radio access at
Business Area Networks,
where he is currently
focusing on analysis and
solutions related to the
architecture, deployment
and functionality required by
5G RAN. After first joining
Ericsson in 1997 to work
with algorithm development,
he later became a system
architect responsible for the
modem parts of 3G and 4G
UE platforms. Östberg holds
an M.Sc. in electrical
engineering from Lund
University.
