Re: stds-802-16-mobile: Sleep window parameters in Table 275a



 
Dear Itzik and Phillip
 
Thanks for your reply...
I think that the listening interval would affect the data receiving time. if the lietening interval is short, it may be happened that the BS shall buffer the data and the data transmission will be delayed...Becuase the short listening interval may deminish the receiving(at MSS) and transmitting(at BS) attempt.Therefore, if the battery of the MSS is enough (e.g the MSS with fixed power in car, train, or something like that...), the MSS would be waiting with relatively longer listening interval. Therefore in your mail the mentioning the MSS wants short listening interal any time may not be correct..As results, it should be allowed that the MSS suggest the listening interval based on its power status.... from my understanding
 
From BS scheduling point of view..
To adjust the exact and effect scheduling point at the BS side, the listening interval should be allocated dynamically to be reflected the traffic pattern..
Even in allocating the fixed listening interval, the real listening interval will be decided based on the traffic pattern (take sleep interval increasing...) And also, because sleep-interval as well as listening interval will be dependent of the traffic pattern and decided when the MSS goes to sleep mode, not exchanging REG-REQ/RSP message(like as current docuement)..Therefore, the allocation of listening interval during REG-REQ/RSP exchanging may not be correct and reflect the traffic status...
 
So my understanding is ...
The MSS suggests the listening interval(based on its power status) and the BS allocate it (based on scheduling policy)..during MOB_SLP-REQ/RSP exchanging same as the original approach
