• absoluteFrequencySSB : It represent the center frequency of SSB Block

• absoluteFrequencyPointA : It represents the common reference point A

• offsetToPointA = It defines the frequency offset between point A and the lowest subcarrier of the RB overlapping with SSB. The unit for RB is expressed as 15KHz for FR1 and 60 KHz for FR2

• Kssb = it defines the frequency of RB#0 of SSB and The unit for RB is expressed as 15KHz for FR1 and 60 KHz for FR2

• dl_offstToCarrier : if dl_offstToCarrier is equal to 0, it means that the starting point of the communication at Point A aligns perfectly with the carrier frequency. There is no shift or difference in frequency; they match up directly. It's like saying they are on the same page in terms of where they are operating in the wireless spectrum.

• Reference

• initialDLBWPlocationAndBandwidth : CORRECTION Max RBs would be 272 hence end point of the exmaple given above would be 272
