RE: stds-80220-requirements: Frequency Re-use, 4.1.3
Neka,
I agree with you that the current text, "allow for system deployment with
frequency reuse factors of less than or greater than 1" is confusing. The
intention was to require that the air interface
support configurations where all frequencies could be used in all sectors
(e.g. N=1). My understanding was that the air interface should be allowed
to support configurations where
frequencies could be used more than once in each sector, i.e. to provide for
but not require support for spatial diversity. This is often referred to as
N<1. For example, N=.5 means that each frequency is used twice in a sector.
Note: Cell sectorization is not a means by which one can reduce N. It is
probably clearest for this requirement to be stated on a "per sector" basis
and to recognize that
an omni-directional cell is considered to be a "single sector" cell.
So, the following is my "friendly amendment" to your proposal.
Proposed Deleted text
“universal frequency reuse but also allow for system deployment with
frequency reuse factors of less than or greater than 1”
Proposed New text
The AI shall support any frequency reuse scenario, on a per sector basis,
with N <= 1.
Frequency reuse (N) is defined as the reciprocal of the number of times a
frequency
can be used in a single sector, recognizing that an omni-directional cell is
referred to as a
"single sector" cell.
Rationale
This change is recommended in an effort to provide a little more clarity.
Best regards,
Joanne Wilson
