[STDS-802-16] Delta between C802.16d-04_73r3 & C802.16d-04_73r1
Hi All,
In my previous email, I addressed the differences between r3 and r2. Roger
pointed out that I should compare r3 and r1, since the comment under
consideration in the ballot is r1. Here are the main differences...
Method #1:
---------
1) In section 3.1.1, AAS-DLFP is 12 bytes long as opposed to 16 bytes. AAS
DLFP has an initial ranging IE and compressed DL IE and these two IEs replace
the two AAS_COMP_IE in r1. BSID, frame number and UCD/DCD change counts are
all eliminated from the AAS-DLFP. A preamble presence bit is introduced in the
AAS-DLFP.
2) In sections 8.4.4.7.1 & 8.4.4.7.2, the construction of the AAS preambles in
the uplink/downlink are explained.
3) In sections 8.4.5.3.8 & 8.4.5.3.9, new PHY modifiers are defined to use
shifted versions of the preambles for SDMA purpose both in the uplink and
downlink.
4) In section 8.4.5.4, removed references to "alert slots" in D4.
5) In section, 6.3.2.3.41, removed references to "direction" in D4.
Method #2:
---------
7) In section 3.2, right under the text '[Add this text as sec 8.4.4.8]' a new
subsection heading '8.4.4.8 Optional AAS Direct Signaling Method' is added.
8) In section 3.2.9.4, FLI initiation codewords are added.
