Hi,

Other than the struc DrxConfig_s in ff_mac_common.h, I guess there is no support for DRX mechanism of LTE in ns3. Has anyone implemented DRX in LTE? If not, can anyone suggest the complexity of the implementation? I have attached the file ff_mac_common.h as well as 3GPP spec for DRX mechanism.

Thanks,
Syama

Hi Syama,

I've been working on PHY and MAC of the LTE module but I'm not an
expert of DRX. However, going rapidly through the document it seems to
me that it should not be too much complex. The work should concentrate
on eNB MAC for implementing the state machine that controls the DRX
cycles (with the correspondent messages of Sec. 5.7) and triggers (or
not) the scheduler based on the current state.

My two cents,
marco.

Hi,

I do not know why I had not received this message notification or reply earlier. I just saw this message. I have started working on it. It seems to be quite invlved but not difficult.

Thanks a lot and sorry for the late reply, I just did not see this mail.

Hi Syama,

Have you implemented the DRX?
Is it connected or idle mode? or both?
Do you plan to upload your source code to the official ns-3 releases?
Do you mind sharing the outline of your change? e.g., which files you changes?

Thanks,
Fei

Hi,

Sorry for the late reply. I implemented DRX in the downlink in ns-3.

Hi,

I implemented DRX for connected mode. I will need to check the files to know which all I changed. I will let you know by evening today. I have no plans to upload my code to ns-3 releases. I have not followed strict coding guidelines and I do not think it's in a shape for release.

Regards,
Syama

Syama,

Thanks. It's very nice of you.
Could you please also let me know about how many hours it took you to finish it? 

Thanks,
Fei

Hi syama,

How is your progress in implementing DRX in ns3.. I'm beginner in using ns3..I'm just wondering if it difficult to implement DRX in ns3.

tq..

I am not doing anything in DRX or ns-3 now. I had implemented it for downlink traffic in ns-3 when I was doing my thesis. I can help if you have some questions. It is not difficult, but time consuming.

hi Syama

am a beginner in ns3 and my thesis is on DRX power saving in idle mode.
If you have already implemented it ( even if it is in connected mode) please send me your file as it will give me a starting point.

Thanks in advance
Robert.

Hi Syama,

I've also recently started working on DRX in ns3. If it's possible, can you share with me how you implemented the mechanism so I can have a rough idea on how to start with mine? I would really appreciate your response.

Thanks,

Hello Multazamah,

i'm trying to implement lte drx in c. Did you have any progress implementing it in ns3?  Would it be easy to share it with me?

Thank you  in advance,

Hi,

Again the same set of questions, I am new in ns3 and wanted to implement DRX, and eDRX so anyone can help me to provide their implementation for me to have quick boost in starting?

Thanks,
Ashish

Dear Syama,
I'm going to implement an alternative version of the DRX mechanism for a mmWave video streaming scenario in ns-3, however I would like to start from the basic DRX procedure for LTE, can you please share the code that you used for your thesis? (if you still have it)

Thank you very much,

Alberto
