Always welcome🙏

or the receive operation which has written on pdcp 3gpp spec

Hi, i am not very expert at this part. I will see what i can do.

@@mohamedeladawiashour ok sir

@ can u suggest best resource for pdcp

Thank you

Thank you

Thank you! Yes, that’s correct as per my understanding. For more detailed information, you can also refer to page 555 in the 5G NR in Bullets book.

@@mohamedeladawiashour ! Great! Thank you very much!!

@robsonbentes8920 you’re very welcome

You are welcome!

Thank you 🙏

Many thanks, i appreciate your kind feedback

Thanks, A) not sure, B) qci5 uses rlc am mode. Thank you

Numerology should remain consistent, especially for TDD. Otherwise, you risk encountering a situation with significant interference due to potential overlap between downlink (DL) and uplink (UL) transmissions.

Thank you. I truly appreciate your feedback.

Thanks, gerogi A) yes, you are right b) not sure c) yes as far as i know

You’re very welcome, thanks for leaving a comment

Thanks a lot for your kind words! The link is already included in the video description. Please take a look and let me know if it’s what you're looking for.

Thank you

Hi not 100% sure but here is my thoughts The Semi-Persistent SRS (SPS SRS) and Aperiodic SRS serve different purposes in 5G: • SPS SRS is pre-scheduled and ensures periodic uplink channel state reporting, reducing control signaling overhead for predictable scenarios like stable users. • Aperiodic SRS is triggered on demand and provides flexibility for dynamic scenarios, such as users in rapidly changing environments, where precise and immediate channel information is required. Having both allows efficient resource usage and adaptability for diverse network conditions.

You're welcome!

You’re welcome, i will do in session 4(last one)

@@mohamedeladawiashour actually i have very much doubt in phy layer how transport block splited in PHY layer and how we executing each step in PHY layer and after how we send this data over the air with modulation technique...i have the overview but still the picture is not clear...pls cover this session it will be very helpful.

Hi Rahul, sure i will consider it

Hi Raghavendra, thank you for your comment! Honestly, I didn’t plan to share the material for this series, but I might consider doing so once I’ve completed the remaining sessions. I’ll let you know either way. Thanks again!

You’re very welcome. Thank you

Thank you 🙏

Thank you, i believe either PUCCH or PUSCH can be used and it depend on the scenario "The RLC Status PDU in the case of DL data transmission is carried on: - PUCCH for small feedback without simultaneous uplink data. - PUSCH for larger feedback or when combined with other uplink data transmissions. As a side note: The above information is based on my logical understanding and has not been directly referenced from any standard documents.

Thank you so much 🙏

Thank you, i wish you like it. I am network design and optimization solution architect but i see this material is very useful as well for RAN engineers not protocol engineers only

Thank you

Okay

Thanks, sure i will do.

@@mohamedeladawiashour will you elaborate MAC and PHY in your next session ?

@praveenRajput_b i will go through TCP/PDCP in next session then i will cover the MAC separately, regarding the physical layer this need a separate series of videos

حببيبي يا محمد من بعض ما عندكم ربنا يزيدك من فضله

Glad it was helpful! Thank you

Thank you

Thank you

Thank you 🙏

Hi Georgi, yes you are correct but one more point to highlight in case 5G NSA for sure PUCCH is there for both PCell(MeNB) and PSCElL(SNB) but it is not available for any scell

Thank you, materials already shared in the video description
