Counters for the distribution of the serving Beam ID (BI) for PDSCH?

RAN

Hello Experts.

How many counters do we have for the distribution of the serving Beam ID (BI) for PDSCH?
In Huawei and/or Ericsson.

Are there 64 separate counters or some other concept is used?

There is no such concept in Huawei, but Nokia has it.

What Huawei has, which is very good, is the footprint pattern of the cell: so called coverage scenario that can have 16 different values.

I’ve seen we have counter to judge beam change from 0 to 1,1 to 0 while using 2 ssb beam for f < 6 GHz.

Thanks you, but for higher number of beams how is the implementation?

Good question. :slight_smile:

I think for FR2 case where we have 32 SSB beams where user can use at a time 1 SSB i.e. 2 layer i.e. 2x2 .

For single cell can we have 32 SSB beams in FR2 then beam switching is valid otherwise if it single beam per cell then it’s like beam mobility.

For fr2 1 cell or cc can have 32 SSB now user can latch on best SSB as per RSRP threshold parameter so beam switching can be possible on basis of L1 RSRP.

For counter part not sure in FR2.
