Environments
IMT-Advanced: Required Test Environments
The critical decisions were made regarding the four “test environments”:
• Indoor
• Microcellular
• Base coverage urban
• High speed
A radio interface technology (RIT) is required to satisfy the minimum performance
requirements of a least one test environment, as specified by the proponent. A set of
RITs (SRIT) needs to meet the requirements in at least two test environments. Later
in the process, after evaluation of the proposals, only RITs or SRITs that meet the
requirements in at least three test environments may proceed to be included in
IMTAdvanced.
It’s possible, for example, for a candidate RIT that meets only one test environment to
proceed through the process and be evaluated. However, during the “consensus
building” process, it would need to join with other RIT partners to form a SRIT
covering at least three test environments in order to be included in the IMTAdvanced
recommendation.

Cell[1] spectral efficiency () is defined as the aggregate throughput of all users
(the number of correctly received bits, i.e. the number of bits contained in the SDUs
delivered to Layer 3, over a certain period of time) divided by the channel
bandwidth divided by the number of cells. The cell spectral efficiency is measured
in b/s/Hz/cell.

A cell is equivalent to a sector, e.g. a 3-sector site has 3 cells.

the SDU delivered to Layer 3, over a certain period of time, divided by the channel
bandwidth and is measured in b/s/Hz. The cell edge user spectral efficiency is
defined as 5% point of CDF of the normalized user throughput. Table 2 lists the cell
edge user spectral efficiency requirements for various test environments.

• IMT.TECH - 4.2
Peak spectral efficiency
• The peak spectral efficiency is the highest theoretical data rate
(normalised by bandwidth), which is the received data bits
assuming error-free conditions assignable to a single mobile
station, when all available radio resources for the corresponding
link direction are utilised (that is excluding radio resources that
are used for physical layer synchronisation, reference signals or
pilots, guard bands and guard times).

The handover interruption time is defined as the time duration during which a user terminal
cannot exchange user plane packets with any base station. The handover interruption time
includes the time required to execute any radio access network procedure, radio resource
control signalling protocol, or other message exchanges between the user equipment and the
radio access network, as applicable to the candidate RIT or SRIT. For the purposes of
determining handover interruption time, interactions with the core network (i.e, network entities
beyond the radio access network) are assumed to occur in zero time. It is also assumed that
all necessary attributes of the target channel (that is, downlink synchronisation is achieved and
uplink access procedures, if applicable, are successfully completed) are known at initiation of
the handover from the serving channel to the target channel.

VoIP capacity was derived assuming a 12.2 kbps codec with a 50% activity factor
such that the percentage of users in outage is less than 2% where a user is defined
to have experienced a voice outage if less than 98% of the VoIP packets have been
delivered successfully to the user within a one way radio access delay bound of 50
ms.

–
–
–
–
–
to provide common understanding of the process for IMT-Advanced
standardization including technical requirements and evaluation guidelines. In
particular, it will enable those not directly involved with the Circular Letter
works to understand procedures better.
to observe current and future development aspects of IMT-Advanced Radio
Interface technology by development parties
to exchange the views among possible proponents for consensus building of the
possible candidate IMT-Advanced RITS
to share IMT-Advanced market and regulatory aspects for the introduction of the
IMT-Advance
to promote more participation from developing countries into the WP5D
activities,
