我自己画了一幅图,描述了N_SSB_CRB和k_SSB的含义。如果有不对的地方,还望大家多指教。
from 38.211 7.4.3.1:
N_SSB_CRB is obtained from the higher-layer parameter offset-ref-low-scs-ref-PRB
from 38.331 FrequencyInfoDL IE:
-- Absolute frequency positionof the reference resource block (Common RB 0). Its lowest subcarrier is alsoknown as Point A. -- Note that the lower edge of the actual carrier is notdefined by this field but rather in the scs-SpecificCarrierList. -- Corresponds to L1 parameter 'offset-ref-low-scs-ref-PRB'(see 38.211, section FFS_Section) absoluteFrequencyPointA ARFCN-ValueNR,
所以,我理解N_SSB_CRB就是CRB0. 6/9号更正:上面的描述是错误的。N_SSB_CRB并非FrequencyInfoDL中的absoluteFrequencyPointA。也即N_SSB_CRB并不一定是CRB0。 |
