Want that the terminal device for receiving SIB#M1 can be in the continuous 20ms that slot T1 starts, the blind examination since the symbol 2 of each slot
The PDCCH of SIB#M1.
Situation 5 can determine that T1 is to be used for transmission type3-PDCCH's if the SS of PDCCH is type3-PDCCH SS
The initial position of time window determines that T2 is the occupancy duration for being used for transmission the time window of the type3-PDCCH, wherein type3-
PDCCH can be INT-RNTI or SFI-RNTI or TPC-PUSCH-RNTI or TPC-PUCCH-RNTI or TPC-SRS-

Example 6, it is assumed that the corresponding X RO of a references object (SSB or CSI-RS), a total of N number of references object.Reference pair
As the primary sign S of the corresponding RACH SS of the corresponding RO of #n is a function relevant with n, it is assumed that S=n*CORESET time domain
The symbolic number occupied, S is no more than (symbolic number+1 that 13-CORESET time domain occupies).Or, it may also assume that, continuous N
The corresponding RACH SS of the corresponding all RO of references object is identical, such as continuous N references object: references object #n, reference pair
As #n+1, references object #n+2 ... ..., references object #n+M-1 have corresponding RO, then this M references object is RO pairs corresponding
The RACH SS primary sign answered is the symbolic number that S=(n mod M) * CORESET time domain occupies, and actually continuous N is joined at this time
