Dear Mo-Han,
I think we
can achieve what you are trying to do with less changes to
current MOB-SLP-RSP.
MOB-SLP-RSP_Message Format(){
Management message type = 51 8
bits
Sleep-approved 1
bit 0: sleep mode request denied
1:enter sleep mode
If(Sleep-approved==0){
After-REQ-action 1
bit
REQ-duration 4
bits
reserved
2 bits
}
else{
Start
frame
6 bits
initial-sleep
window
6 bits
final-sleep
window
10 bits
listening
interval
4 bits
final-sleep window
exponent 3
bits
sleep-duration 8
bits in units of MAC frame that MSS has to remain in sleep
mode.
it shall not awake to any events before the duration is
over.
"sleep
duration==0 indicates there is no requirement for sleep
duration."
SLPID
10 bits
}
}
Regards,
Kang

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 message
and shall await the MOB-SLP-RSP message from the BS
0b10 - Enter sleep mode
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) {
Start frame
Initial-sleep window
Final-sleep window base
Listening interval
Final-sleep window exponent
SLPID
If(action code == 11) {
sleep duration
}
}
-----------------------------------------------------------------------------------------------------------------
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".
