Feedback mechanism is bit different then legacy for PMI beam… as per 3gpp also.
Hmm… to me it sounds like multiple distributed SS/PBCH blocks can occupy any raster position…
Not that are multiple SSB blocks in frequency domain.
Anyway, just asking: has anyone seen multiple SSB blocks in frequency domain?
Just wonder how would be configured relatively to point A.
Doesn’t it mean multiple SSBs in frequency domain at one point of time?
I think it means that SSB blocks, multiple SSB blocks in time, can ocupy any position in frequency.
Not seen. Just theoretically I am saying that it is possible.
The question arises from the discussion of same cell sharing SA and NSA.
Think about it: would you have multiple PBCH since you have multiple SSBs?
How can freq domain location of SSB change dynamically? It’s fixed.
It is fixed after you fix it.
But in theory it can be anywhere.
This is what it says.
20 PRBs can be located anywhere inside the band.
Not necessarily, PBCH content can be same.
SSB location is conveyed to UE in RRC recon or through broadcat messgae, its not changeable.
But no provision in specs given to make its position change over the time.
Multiple SSB is more relevant for higher bandwidth.
I am not saying it changes over time. I am saying that that phrase sounds more like this “multiple SSB/PBCH block can be anywhere in frequency domain”.
For me that phrase still doesn’t sound that we can have multiple SSB in frequency domain.
It sounds that the multiple SSB blocks ( spread in time) can be located anywhere in frequency domain.
Please dont forget word “Distibuted”.
Multiple SSBs can be distributed across the channel BW.
Ok. Anyone to post an example from logs?
I have seen only single SSB configured up to now.
Exactly. otherwise UE need m-gap to measure SSB
Even I have not seen @RFSpecialist. We’re discussing theory.
If you have seen 400 MHz network, and BWP specific for services - urllc , embb - there you will see these.
A UE can be configured with up to 4 downlink Bandwidth Parts per carrier and up to 4 uplink Bandwidth Parts per carrier.
Only a single Bandwidth Part per carrier can be active in each direction.
A UE receives the PDCCH and PDSCH only within an active Bandwidth Part.
A UE transmits the PUCCCH and PUSCH only within an active uplink Bandwidth Part.
A UE can complete measurements outside the active Bandwidth Part but this can require the use of Measurement Gaps.
This (in bold) is the case when UE do not support full channel BW, and SSB falls outside its current active BWP.
Yes, correct.
I cannot find mention of SSB or SS/PBCH in text.
It simple say measurement. Not that it cannot be CSI-RS right?
CSI-RS is present in active BWP also.
So assume its SSB 
This is valid for case where ssb is outside active bwp (and active bwp has no ssb) - then it is more like an inter freq - need gaps to measure ssb.
