Instructions
This contribution provides clarification on the E-MBS MAP in IEEE 802.16m Amendment Draft Standard [1]. The E-MBS MAP is pointed by the AAI_E-MBS-CFG MAC Control Message. The E-MBS MAP can help AMS skip to decode AAI_E-MBS-CFG MAC Control Message according to the AAI_E-MBS-CFG Change indication.
Note:
The text in BLACK color: the existing text in the 802.16m Amendment Draft Standard

The text in BLUE color: the new text added to the 802.16m Amendment Draft Standard Text
--------------Start of Proposed Text---------------------------------------------------------------------
[Modify the 16.3.6.2.3 of 802.16m/D3 as follows.]
16.3.6.2.3 Enhanced Multicast Broadcast Service MAP (E-MBS MAP)
The E-MBS MAP carries some configuration information for enhanced multicast broadcast service for one EMBS Zone. The E-MBS MAP is pointed by the AAI_E-MBS-CFG MAC Control Message described in 15.9.3.1and is transmitted in the first several resources units of the E-MBS region in the beginning of the MSI. The parameters of the E-MBS region and the burst size of the E-MBS MAP is transmitted in the AAI_E-MBS-CFG MAC control message described in 16.9.3.1. AAI_E-MBS-CFG Change Indication indicates any change in the parameters of AAI_E-MBS-CFG MAC Control Message at its next transmission instance.

AAI_E-MBS-CFG Change Indication
|
1
|
AAI_E-MBS-CFG Change Indication indicates any change in the parameters of AAI_E-MBS-CFG MAC Control Message at its next transmission instance.
If it is set (AAI_E-MBS-CFG Change Indication = 1), parameters in the AAI_E-MBS-CFG message will change and AMS should shall decode the next AAI_E-MBS-CFG message.
Otherwise, the AAI_E-MBS-CFG message does not change and the AMS can resets the allocation Allocation lifetime Lifetime value as defined in the previous AAI_E-MBS-CFG message and may not decode the next transmission.
|
S-SFH SP2 update indicator
|
1
|
Indicates whether the changed S-SFH SP2 will be transmitted in this MSI.
If this field is set to 1, the time offset which the changed S-SFH SP2 is transmitted will be included in this E-MBS MAP.
|
If (S-SFH SP2 update indicator ==1) {
|
|
AMS shall wake up every S-SFH SP2 transmission period until the AMS receives the changed S-SFH SP2.
|
S-SFH SP2 transmission time offset
|
Variable
|
Indicates the superframe offset which the changed S-SFH SP2 is changed.
The size of this field depends on MSI

MSI == 0b10: 3 bits
MSI == 0b11: 4 bits
