Definition of
Marianna and Joanne have
provided some good suggestions which I have incorporated in the following revised
definition:
Coverage Enhancing
Technologies: In the context
of wireless communications - technologies that augment the
radio signal, in areas within the boundary of a cell, where the
BS/MS transmit-signal is obstructed and significantly attenuated by
terrain or man-made structures. Such technologies employ
devices such as repeaters, relays, leaky coax etc. that rely on
the BS they extend from for backhaul communications as well
as Micro/Pico cells that do provide their own backhaul connectivity. The
term Repeater typically refers to an analog device that amplifies and
retransmits the original transmission (without frequency translation). A
Relay (analog or digital) typically retransmits the received signal in
another frequency. A digital relay (or regenerator) decodes the information
from the received signal, regenerates and retransmits it. In the case
of packet communications, relays may also perform Layer-3 functions as
well as delayed transmission.

Definition of
I find your definition of
a "Coverage Enhancing Technology" as being essentially a
repeater. My understanding of the email discussion is that people were
looking for more flexibility in how proposals address coverage holes.
Instead, I
propose an alternative, more flexible definition which includes repeaters
and other approaches:
Coverage
Enhancing Technologies (CETs), are technologies that can provide radio coverage to places that
are hard to reach from macrocellular base stations. Examples of CETs include,
but are not limited to, repeaters, store and forward relays, microcells and
pico-cells, and leaky cable systems (which are typically used in tunnels), etc.
I also don't think we
need to define repeaters, relays, etc. as they are standard within the industry.

As requested in the last System
Requirements CG call, a definition of the term "Coverage Enhancing
Technologies" is proposed below.
Coverage Enhancing
Technologies: In the context of wireless
communications - technologies that augment the radio signal, in
areas within the boundary of a cell, where the
BS/MS transmit signal is obstructed and significantly attenuated by
terrain or man-made structures. Such technologies employ devices
such as repeaters and relays that rely on the BS for backhaul communications.
The term Repeater
typically refers to an analog device that amplifies and retransmits the
original transmission (without frequency translation). A Relay (analog
or digital) typically retransmits the received signal in another frequency. A
digital relay (or regenerator) decodes the information from the received
signal, regenerates and retransmits it. In the case of packet
communications, relays may also perform Layer-3 functions.
