There has been significant progress in the redcap trial that benefits smaller IoT devices thanks to Mediatek's relationship with Nokia RAN portfolio and BT group site allocation.
1. I have a fundamental question that relates to Dual Connectivity i.e. N-DC refers to the dual connection of 4G wireless access network and 5G NR. 2. Let’s say that we are using Band-X in 4G and another similar band in 5G and are attempting to communicate with both RATs to take advantage of EN-DC. 3. The question is what will happen if there is overlap in terms of the “spectrum occupied”. 4. Let’s say that the 4G component has been assigned spectrum in Band 3 from 1830 MHz through to 1850 MHz (i.e. a chunk of 20 MHz Bandwidth). 5. Let’s say that the 5G component has been assigned spectrum in Band n3 from 1820.45 MHz through to 1830.45 MHz (i.e. a chunk of 10 MHz Bandwidth). 6. In such a scenario, there is an overlap of 450 KHz between these two components i.e. the assigned 5G-NR band component eats into the 4g spectrum component by 450 KHz. 7. Will such a deployment work in light of the designated configuration based on existing product implementations? There are bound to be issues in decoding such transmissions at the UE because of the overlap in the spectrum. The reason, I am asking this question was because an argument (however erroneous) can be made that the 5G transmissions would potentially be orthogonal to the 4G transmissions (even if they have an SCS of 15 kHz or 30 kHz) and hence the decoding at the mobile will work because orthogonality will prevent any decoding issues. I do not agree with this argument i.e. that the orthogonality provided by the OFDM structure of the waveforms would protect them against each other (i.e. from the UE perspective in the sense that the UE can successfully decode the two transmissions). I would be very grateful if you could enlighten me with your perspective with references (if applicable). 8. If the answer is in the negative, from an R&D implementation, perspective - what changes would one need to implement to make such a configuration (i.e. characterized by overlapping assigned spectrums) workable in realistic network implementations? 9. It would also be immensely helpful if you could further substantiate your arguments with references from the relevant 3GPP specifications (or other relevant specifications) or draw my attention to any specific specifications or publications which can further clarify my doubt?

Great, but please, for the next training courses add English subtitles integrated with the videos because this is very important for whose English language is not the first language; for example in this case, I can't join any course, because the coach or trainer speak English very fast ;
@@AwardSolutionsInc Thank you for your support and understanding, untill now I'm do my best to finish some academic work related to my study; so, I'm so interseted in your next courses of 5G and its topics in the near future, I suggest "if possible" in future courses to "add" English subtitles integrated on the videos, this will be a powerfull and very intersting training; I know maybe it's demand some efforts, but for my opinion as I'm not English native speaker it will be very excellent and attractive especially you deliver amazing animations within the training explanations :)
The number of beams supported are vendor specific and largely dependent on FR1 vs. FR2. Massive MIMO 64 or 32 represents that many unique RF paths and that'd help support multiple layers of transmission both for SU and MU-MIMO. Hope that helps.
I have a Question will dual connectivity work with other neighboring cell sites in the same area as long as one of the cell sites is the master cell because right now our cell phones can see the neighboring cell sites but cannot talk to them
