* Several cases have to be handled differently as IQ symbols are situated in different parts of rxdataF:
* 1. Number of RBs in the system bandwidth is even
* 1.1 The RB is < than the N_RB_DL/2 -> IQ symbols are in the second half of the rxdataF (from first_carrier_offset)
* 1.2 The RB is >= than the N_RB_DL/2 -> IQ symbols are in the first half of the rxdataF (from element 1)
* 1.2 The RB is >= than the N_RB_DL/2 -> IQ symbols are in the first half of the rxdataF (from element 0)
* 2. Number of RBs in the system bandwidth is odd
* (particular case when the RB with DC as it is treated differently: it is situated in symbol borders of rxdataF)
* 2.1 The RB is <= than the N_RB_DL/2 -> IQ symbols are in the second half of the rxdataF (from first_carrier_offset)
* 2.2 The RB is > than the N_RB_DL/2+1 -> IQ symbols are in the first half of the rxdataF (from element 1 + 2nd half RB containing DC)
* 2.2 The RB is > than the N_RB_DL/2+1 -> IQ symbols are in the first half of the rxdataF (from element 0 + 2nd half RB containing DC)
* 2.3 The RB is == N_RB_DL/2+1 -> IQ symbols are in the lower border of the rxdataF for first 6 IQ element and the upper border of the rxdataF for the last 6 IQ elements
* If the first RB containing PDCCH within the UE BWP and within the CORESET is higher than half of the system bandwidth (N_RB_DL),
* then the IQ symbol is going to be found at the position 1+c_rb-N_RB_DL/2 in rxdataF and
* then the IQ symbol is going to be found at the position 0+c_rb-N_RB_DL/2 in rxdataF and
* we have to point the pointer at (1+c_rb-N_RB_DL/2) in rxdataF
