Hi, everyone,
Below are my two-cents on the issue of the
repeaters.
- The use of repeaters is a
performance enhancement issue. In some situations, repeaters make sense. While
in others, there are alternative ways as well. A mandatory requirement seems
too strong.
- The impact on the AI is subject
to investigation. It may be a little too early to conclude that the system
has to support huge delay or delay spread.
Best,
Junyi Li

Joanne et al.,
Support for the use of
repeaters needs to be a mandatory requirement because operators need to have
this tool in their tool box to economically provide in-building coverage and in
lightly populated areas. If you recall from the presentation in Singapore
that KTF uses allot more repeaters than base stations in their network. The
same trend is also occurring in the US.
The impact on the AI is
that the system has to support larger delay's and delay spreads.

It's not
clear to me the AI design implications of the changes you have made.
However,."should support" implies that
support
for repeaters is optional. Changing to "must not preclude"
makes it a mandatory requirement. This change,
at least
to me, doesn't clarify the rationale so much as changes requirement
itself. I support maintaining the previous wording of the requirement
until we have a better understanding of the implications of the change and the
rationale for such.
