Intro.
Current Design
• Broadcast assignment A-MAP for broadcast burst allocation
• All broadcast MAC control messages to be transmitted in a AAI subframe shall be included in a broadcast burst.
Need to Decide
• (1) IE contents for Broadcast assignment A-MAP
• (2) Location of Broadcast assignment A-MAP
• (3) Transmission format for Broadcast assignment A-MAP
IE Contents (1/2)
Information Element
• [A-MAP IE Type: 4 bits]
• May not be required if TBCC code rate of Broadcast assignment A-MAP IE is different from that of assignment A-MAP IE.
• Resource index: 11 bits
• MCS (ISizeOffset)
• Recommend implicit signaling
IE Contents (2/2)
MCS
(1) Need to consider both reuse 1 and reuse 3
(2) The lowest code rate of CTC (≈1/12) is enough to meet 5% outage requirement in reuse-1?
Cannot meet requirement in EMD baseline test scenario (Appendix)
(Proposal) use additional code rate of ≈1/24
(3) Explicit or Implicit indication?
(Proposal) implicit method: mapping to S-SFH code rate (not defined in D3)
Location of Broadcast A-A-MAP
(Proposal) Assignment A-MAP
• In primary frequency partition, only one Broadcast A-A-MAP IE is present at the beginning of either group 1 or group 3 in A-A-MAPs, if exist.

Text Proposal
[Remedy 1: Add the following text after line 48, page 369, 16.3.6.2.2.4]
----------------------------------------------------- Text Start ----------------------------------------------------
In primary frequency partition, a Broadcast assignment A-MAP IE is present at the beginning of either group 1 or group 3 in assignment A-MAPs, if exist.
----------------------------------------------------- Text End -----------------------------------------------------
Text Proposal
[Remedy 2: Modify the following text in line 16, page 443.]
----------------------------------------------------- Text Start ----------------------------------------------------
16.3.6.5.2.4.13 Broadcast Assignment A-MAP IE…
Table 829—Broadcast Assignment A-MAP IE*
Text Proposal
*A 16 bit CRC is generated based on the contents of the Broadcast Assignment A-MAP IE
The broadcast message signaled by the Broadcast A-MAP IE is always transmitted using SFBC as the MIMO encode format.
Resource Index field is interpreted as in the DL Basic assignment A-MAP IE, except for allocation of size 1 and 2 LRUs. Allocation of size 1 and 2 LRUs is not allowed for broadcast data bursts.
When calculating the burst size of broadcast data burst, ISizeOffset is implicitly indicated based on code rate of S-SFH and frequency partition index as shown in Table yyy.
