Change "{N_Groups}" by "N_Groups". Also in page 32, line 6 and page 35,
line 9.

[Reason for Edit]
To correct notation. As it is in the text, this term indicates a number,

not a series.

[Detailed Description of Proposed Insertion, Deletion, Change]
Insertion at the end this line of  "The number of basic groups,
N_Groups, is equal to the number of data carriers per subchannel (48 in
DS and 53 in US). Each basic group is made up of adjunct carriers. The
number of the carriers in a basic group is equal to the number of
possible subchannels. As a result of the carrier allocation procedure,
each subchannel is built taking one carrier from each basic group."

[Reason for Edit]
To clarify the basic group concept and the procedure for allocation of
carriers into subchannels.

Insert at the end of the sentence "N_elements is equal to the number of
possible subchannels."

[Reason for Edit]

[Detailed Description of Proposed Insertion, Deletion, Change]
Change this sentence by "Different permutations ({PermutatedSeries_s})
are achieved by cyclically rotating s times the {PermutatedBase_0} to
the left. {PermutatedSeries_s} will be used to obtain allocation of the
carriers of subchannel s".
This change involves changing "{PermutatedSeries}" by
"{PermutatedSeries_s}" in points 4 and 5 of the procedure definition in
page 31 and in Section 8.

[Reason for Edit]
To clarify the carrier allocation procedure. It is not clear which is
the relation between permutated series and subchannels. In the proposed
correction, an association between subchannel and permutated series is
presented.

[Detailed Description of Proposed Insertion, Deletion, Change]
Start sentence with "To get a N_Sub-Channel length series (being
N_Sub-Channel the number of data carriers per subchannel) we
concatenate..." instead of  "To get a {N_Sub-Channel} length series we
concatenate..."

[Reason for Edit]
To clarify the meaning of N_Sub-Channel.

[Detailed Description of Proposed Insertion, Deletion, Change]
Change lines 20 and 23 by
"Let p_s[j] the j-th element of {PermutatedSeries_s} (j starting from
0). The k-th element of the resulting concatenated series, c_s[k], is
obtained by the next formula:

c_s[k] = {p_s[k mod(N_elements)] +
ceil[(k+1)/N_elements]·CellId}mod(N_elements)

where ceil(x) rounds x to its closest upper integer; k = 0,1,...,
(N_concatenation-1); and CellId is a MAC defined parameter, defining the

current cell identification numbers, to support different cells. Then,
we take the first N_Sub-Channel elements."

The series {PermutatedSeries_s} was defined in a previous comment.

[Reason for Edit]
To simplify and clarify the formula with a closer expression.

Change lines 26 and 27 by "The last step achieves the carrier numbers
allocated for the specific Sub-Channel with the current CellId. Using
the next formula we achieve the N_Sub-Channel carriers (48 in DS, 53 in
US) of the current permutation in the cell:

carrier(n, s) = N_elements*n + c_s[n].

Here carrier(n, s) is the n-th carrier of subchannel number s; n =
0,1..., (N_Sub-Channel - 1).".
c_s[n] and p_s[n] were defined in previous comments.

[Reason for Edit]
To clarify the meaning of the formula.

it was proposed to associate subchannel number s with
{PermutatedSeries_s}.

[Reason for Edit]
