determine that the configuration of search space zero indicates a Physical Downlink Control Channel (PDCCH) repetition;

receive Downlink Control Information (DCI) corresponding to a System Information Block 1 (SIB1) from the network equipment based on the configuration of search space zero, wherein the DCI includes scheduling information of Physical Downlink Shared Channel (PDSCH) corresponding to the SIB1; and

receive downlink data via PDSCH according to the scheduling information of PDSCH.

2. The UE of claim 1 , wherein the at least one processor is further operable to:

detect the DCI in a first PDCCH monitoring occasion and a second PDCCH monitoring occasion following the first PDCCH monitoring occasion, wherein the first PDCCH monitoring occasion and the second PDCCH monitoring occasion are within a first slot.

3. The UE of claim 2 , wherein the at least one processor is further operable to:

detect the DCI in a third PDCCH monitoring occasion and a fourth PDCCH monitoring occasion following the third PDCCH monitoring occasion, wherein the third PDCCH monitoring occasion and the fourth PDCCH monitoring occasion are within a second slot immediately following the first slot.

4. The UE of claim 1 , wherein the scheduling information indicates that an index of a starting Orthogonal Frequency Division Multiplexing (OFDM) symbol is not less than 4.

5. The UE of claim 1 , wherein the scheduling information complies with PDSCH time domain resource allocation corresponding to type B of PDSCH mapping type in a default PDSCH time domain resource allocation table.

6. The UE of claim 5 , wherein type B of PDSCH mapping type in the default PDSCH time domain resource allocation table supports PDSCH duration of n number of Orthogonal Frequency Division Multiplexing (OFDM) symbols, where n is a natural number within 2 to 10, and wherein one or more types of PDSCH mapping type of the default PDSCH time domain resource allocation table comprise type B of PDSCH mapping type.

7. The UE of claim 1 , wherein the at least one processor is further operable to:

detect the SIB1 within a first slot; and

detect at least one second SIB1 within a second slot, wherein a time difference of N*20 milliseconds is between a starting Orthogonal Frequency Division Multiplexing (OFDM) symbol of the first slot and a starting OFDM symbol of the second slot, where N is a natural number.

8. The UE of claim 1 , wherein the at least one processor is further operable to:

detect the SIB1 within a first slot; and

detect at least one second SIB1 within a second slot, wherein a time offset is between the first slot and the second slot.

9. The UE of claim 1 , wherein a PDCCH candidate is associated with an aggregation level and a repetition number of the PDCCH repetition.

10. A network equipment for wireless communication, comprising:

at least one memory; and

at least one processor coupled with the at least one memory and operable to:

transmit a Master Information Block (MIB) corresponding to a Synchronization Signal Block (SSB) to a user equipment (UE), wherein the MIB includes a configuration of search space zero for the UE to determine that the configuration of search space zero indicates a Physical Downlink Control Channel (PDCCH) repetition;

transmit Downlink Control Information (DCI) corresponding to a System Information Block 1 (SIB1) to the UE based on the configuration of search space zero, wherein the DCI includes scheduling information of Physical Downlink Shared Channel (PDSCH) corresponding to the SIB1; and

transmit downlink data via PDSCH according to the scheduling information of PDSCH.

11. The network equipment of claim 10 , wherein the at least one processor is further operable to:

transmit the DCI in a first PDCCH monitoring occasion and a second PDCCH monitoring occasion following the first PDCCH monitoring occasion, wherein the first PDCCH monitoring occasion and the second PDCCH monitoring occasion are within a first slot.

12. The network equipment of claim 11 , wherein the at least one processor is further operable to:

transmit the DCI in a third PDCCH monitoring occasion and a fourth PDCCH monitoring occasion following the third PDCCH monitoring occasion, wherein the third PDCCH monitoring occasion and the fourth PDCCH monitoring occasion are within a second slot immediately following the first slot.

13. The network equipment of claim 10 , wherein the scheduling information indicates an index of a starting Orthogonal Frequency Division Multiplexing (OFDM) symbol is not less than 4.
