（3）CRB, Point A, BWP
（refer to 38.211/38.213/38.104/38.331)
**Per carrier configurations:
FrequencyInfoDL and FrequencyInfoUL (FreqInfoUL only for FDD/SUL)
l
absoluteFrequencySSB
defines the center frequency of SSB (
sc#0 of #prb10 of SSB
, SSB occupies 20prbs in frequency domain)
l
absoluteFrequencyPointA
in freqInfoDL defines Point-A in DL, which is sc#0 of CRB#0
l
absoluteFrequencyPointA
in freqInfoUL defines Point-A in UL(for FDD/SUL only), which is sc#0 of CRB#0
However, the actual NR carrier is defined in scs-SpecificCarrier:
l
offsetToCarrier
defines the actual usable BW w.r.t. the carrier’s Point-A, which is the CRB
as defined in 38.211 4.4.2.
l
subcarrierSpacing
defines scs of the carrier, which is parameter–nrScs in Section 1.3.1
l
carrierBandwidth
defines N_RB of the carrier, which is parameter—nrBw in Section 1.3.1, which is also the
as defined in 38.211 4.4.2.
offsetToCarrier shall have no impact to Resource Grid implementation.
Let offsetToCarrier = 0
?
Rational as below:
k_SSB is the sc offset from
