Deploying Converged Packet Fronthaul - LTE Resource Allocation | Frequency Domain | Time Domain

[@packetxhaul]

Hope you watched the first video of our "Deploying Packet Fronthaul Router" series. You will find this second episode useful too, it talks about the LTE Resource Allocation in Frequency and Time Domain. If you like our work, please drop a like a SUBSCRIBE to the channel, for future videos. Cheers.

For me every bit of this information is found useful. Kindly give references, related video links in description box to acquire this knowledge. kindly keep up this great work and waiting for next video

[@packetxhaul]

Thank you so much, Anjan. Thanks for that suggestion, will provide references in description below. Many more videos to come. Stay with us.

Thanks for the nice video , one question please , if you mind to answer. One Radio Frame =307200*Ts=10msec , what is 307200 here?

[@packetxhaul]

Thank you so much. So, in FDD, we can take samples of these radio frames. The number of samples in one frame = 307.2 K or 307200 (10 ms). Which means samples per second = 30.72 M --> This is our standard LTE Sampling Rate.

@@packetxhaul So if this is standard for a particular Channel BW right. Will you be able to relate with the fft size for a 20Mhz. So for 20 Mhz we know that fft size is 2048, as Subcarrier is 1333 or approx 1200. I mean my question is to understand the relation between fft size and the sampling rate for a particular Channel BW

@@pratiksarkar6361 Hi Pratik...there is a relationship, it is difficult to explain everything in this comments column, it's a simple maths. Please can you check it out here ->www.sharetechnote.com/html/Handbook_LTE_PhyParameter_DL_FDD.html

the indication of the entity must be put inside the two converging arrows: the slide with frame, subframes, and slot, read as it is show a subframe from slot 2 to slot 10 .. next slide you talk about sub-carriers without defining them in frequency ..

Do not understand why 1.25, 2.5 MHz are dicussed as possible LTE bandwidths. This was done in very early discussions of LTE (about 2007/8) and it has lead to 1.4, 3, 5,.... MHz as possible bandwidths for LTE (6, 15, 25,.... PRB) for commercial solutions.

[@packetxhaul]

You are absolutely correct, Karl. We have updated our current calculators, all are based on the 1.4, 3,5,10,15,20 MHz LTE.
