When are the RRC Parameters for Beam Failure Detection sent in the RRC reconfiguration message?

5G NR

I mean beam failure recovery.

42

Ok, my chipset is different in DSS. Maybe that can be one reason?
X50 in mmwave logs vs X55 in DSS.

43

No idea…
I also have a X50 UE and beam failure recovery is configured in n78.

44

So in X50 UE do you have any of this 2 logs?

45

Yes, I do have boh of them.

46

Oh, ok. mmWave?

47

Nope.
n78 3.5 GHz TDD.
6 beams.

48

So maybe your beams >0 so BFR will be there?
But I can’t see in 8 beam mmWave. :frowning:

49

You need to check all messages.

50

RIght. I noticed it now in DSS so went back to mmWave and couldn’t find it.

51

The Ue need to be capable of SSB RLM :

  measAndMobParameters 
    measAndMobParametersCommon 
      ssb-RLM supported
52

Beam failure is only for R16 UEs.
Cause of RACH should be beam failure, not t310 expiry.

53

How one could recognise R15, R16 supported device in a box or OEM website?

54

But I see this UeCP message under RRc Rel 15 for SSB RLM.

55

But have you seen a RACH with cause beam failure in NR?

56

No, I haven’t seen any beam failures yet, neither in RACH nor in PDSCH.

57

I have seen this. In qc device, release 15.
Again, I talk about simulated environment only…

58

Hi, pls help to understand this?

What is the unit value of beamfailuredetection timer.? i mean what does this pbfd stands for and what are these pbfd1 , pbfd2 , pbfd8 means?

59

beamFailureDetectionTimer

beamFailureDetectionTimer whose value is given in unit “pbfd”.

How this unit will be converted in msec or second?
