Hi Mo-Han,
I have some editorial comment on the "Enhancement to Normal Mode to Sleep Mode Transition (rev 2).pdf
".
In the Table 92b (actuallly, Table
106b),
Management Message Type = 46 --> 51 From
Action code
2bit
0b00 - Enter sleep mode
0b01
- Enter sleep mode for 'sleep duration'.
The MSS shall not initiate to enter normal mode during the sleep
duration.
0b10 - remain in normal mode. The MSS may retransmit the
MOB_SLP_REG message
after
the time duration (REQ-duration) given by the BS in this message.
0b11 - remain in normal mode. The MSS shall not retransmit
the MOB-SLP-REQ message
and
shall await the MOB-SLP-RSP message from the BS
If(action code == 00 || 01) {
Start frame
Initial-sleep
window
Final-sleep
window
Listening
interval
Final-sleep window
exponent
SLPID
If(action code == 01)
{
sleep
duration
}
}
else if (code == 10 {
REQ-duration
}
To
Action code
2bit 0b00 - remain in normal mode. The MSS may retransmit the
MOB_SLP_REG message
after
the time duration (REQ-duration) given by the BS in this
message.
0b01 - remain in normal mode. The MSS shall not retransmit the MOB-SLP-REQ

0b10

0b11
- Enter sleep mode for 'sleep duration'.
The MSS shall not initiate to enter normal mode during the sleep
duration. If(action code ==
00) {
REQ-duration }
else if(action code
== 10 || 11) {

If(action code == 11) {

}
-----------------------------------------------------------------------------------------------------------------
In the above scheme, we can show that the action code (2bits)
is consist of Sleep-approved (1bit) and After-REQ-action (1bit) in
P802.16e/D4.
As you may know,
Sleep-approved, "1" means "Sleep-mode request
approved".
After-REQ-action, "1" means "The MSS shall
not retransmit the MOB-SLP-REQ message and shall await
the MOB-SLP-RSP message from the BS".
Therefore, action coe, "11" means "Sleep-mode request approved
and the MSS shall not retransmit the MOB-SLP-REQ message, so the MSS can
sleep".
