In a configuration of FIG. 16(7), each CORESET occupies 2 symbols, where a CORESET of the first SSB occupies the first and second symbols in a former slot; a CORESET of the second SSB occupies the third and fourth symbols in the former slot; a CORESET of the third SSB occupies the first and second symbols in a latter slot; a CORESET of the fourth SSB occupies the first and second symbols in a slot outside a 5 ms SSB time window; and ‘time domain spacing between the CORESET of the first SSB and the CORESET of the fourth SSB’ is equal to 5 ms.
In a configuration of FIG. 16(8), each CORESET occupies 2 symbols, where a CORESET of the first SSB occupies the first and second symbols in a former slot; a CORESET of the second SSB occupies the third and fourth symbols in the former slot; a CORESET of the third SSB occupies the first and second symbols in a former slot; a CORESET of the fourth SSB occupies the first and second symbols in a slot outside a 5 ms SSB time window; and ‘time domain spacing between the CORESET of the second SSB and the CORESET of the fourth SSB’ is equal to 5 ms, or ‘time domain spacing between the CORESET of the third SSB and the CORESET of the fourth SSB’ is equal to 5 ms.
In a configuration of FIG. 16(9), each CORESET occupies 1 or 2 or 3 or 4 symbols, a multiplexing manner of FDM is used for CORESETs and corresponding SSBs, that is:
