- * As per FAPI spec, 
- * Frequency domain resources is a bitmap defining non-overlapping groups of 6 PRBs in ascending order.
- * [TS38.213 10.1]. Bitmap of uint8 array. 45 bits.
- *
- * As per IAPI,
- * CORESET-freqdom.frequencyDomainResources : The bits of the bitmap have a one-to-one mapping with
- * non-overlapping groups of 6 RBs. The most significant bit of the first word corresponds to
- * the most significant bit defined in 38.331.
- *
- * FAPI and IAPI both are 45 bits. Mapped from bit 0 LS Byte for the FAPI and
- * bit 0 LS U32 entry for IAPI.
- * FAPI is to be filled in following format such that Intel L1 is able to decode it :
- *
- *            FAPI                                 IAPI 
- * FreqDomainResource[0] bits 7-0     ->    nFreqDomain[0] bits 7-0
- * FreqDomainResource[1] bits 7-0     ->    nFreqDomain[0] bits 15-8
- * FreqDomainResource[2] bits 7-0     ->    nFreqDomain[0] bits 23-16
- * FreqDomainResource[3] bits 7-0     ->    nFreqDomain[0] bits 31-24
- * FreqDomainResource[4] bits 7-0     ->    nFreqDomain[1] bits 7-0
- * FreqDomainResource[5] bits 7-0     ->    nFreqDomain[1] bits 15-8
- *
- * where for the last entry bits 7,6 and 5 are don't care in the FAPI and bits
- * 31-13 are don't care in the IAPI.
