So, CID is not indicate SS? Even for time when SS is connected to BS? When CID is going to free pool - when SS disconnects? Or when downloading of some data is finished?..
Dear Ahmad
Do you know , How can i manage the physical profile in opnet , for frequency reuse 3?
Thank you.
CAN YOU SHARE A9116 COMMISIONING MANUAL?
NEED IT VERY MUCH
hi, your first statement is correct. i am not able to interpret the second statement.
For UGS, every UL frame BS assigns the bandwidth(depends upon your provison) to the CPE (5 ms one frame)
For ex:
you are provisioned 1Mbps UL in UGS .
if you are…
Hi,
can i join with your research... I am also intersted doing this.
Advanced thanks.

Hi,
I guess it will not use all methods in single frame.
For ex:
SS can use the Piggy bagging BWR (one message to request the complete Bandwidth)
Contention based random access:
SS sends the BWR CDMA Code, to get 6 bytes of Bandwidth for requesting…
Hi Suresh,
Your procedure is correct in the sense that you are testing the receiver sensitivity of your MS.
In your wired setup you are using an attenuator and testing the CINR against the noise floor of your receiver (MS receiver in this case). S…

How are you doing,
Can you help me in a concept- Reauthentication ( Session resumption)
i wanted the message flow and the situation when the session resumption or full authentication will be triggered.

- Thanks Suresh, for the reply.
i have read that, if there are 3 cells that are using same frequency(i.e cell reuse= 1) then the cell centre will be using the FUSC permutation and the cell edge will use the PUSC permutation.
now the question is:
1. Is there any algorithm for allocation of FUSC and PUSC in a cell.
2.what will be the diameter of the cell centre?
3. If there is the PUSC used at the cell edges then there will be interference, how will it be avoided.
4. how is this different from the frequency reuse 3?
can any one clear my doubts?
Thanks in advance

- Hi Suresh,
how are you doing????
i hav got a question for you, can you tell me what is the significance of Freq. reuse in Wimax.

- Hi Suresh, I have many papers about scheduling and cac mechanisms. I don't know what kind of papers are you looking for, so I have attached a report which presents a general idea of the QoS support in WiMAX networks.

Hassan Naqvi said… - Hello Suresh, I read your query on the forum, and thought to share my little knowledge that i have. Well the significance of Preamble index arises in the initial network entry stage. During the DL synchronization, the MS listens for the DL frame preambles. When one is detected, the MS can synchronize (initial synchronization includes both timing and frequency synchronization) itself with respect to the DL transmission of the BS. When the synchronization is complete, MS then listens to other control messages like FCH, DCD, UCD,UL-MAP and DL-MAP to obtain the various PHY and MAC related
parameters corresponding to the DL and UL transmissions. Preamble index points to the index of DL Frame's preamble, and from my practical experience i must tell you it varies from sector to sector for obvious reasons. I hope it addresses your concerns a little.
