section, in order to remove all sub-section headers of more than 6 levels deep.
Purpose
To be discussed and adopted by TGm for the 802.16m Advanced Air Interface (Draft 1)

Proposed ToC clean-up of DL MIMO section 15.3.7

Introduction
The DL MIMO section 15.3.7 in [1] has section headers of levels 7 to 10 (such as 15.3.7.2.6.6.2.1.2 MU-MIMO
base codebook), whereas the style guidelines only allow headers up to level 6. As a result, a lot of cross
references are broken in the document. This contribution proposes a logical re-organization of the DL MIMO
sections, without affecting the contents. This organization is consistent with the UL MIMO section.
