Method of monitoring paging occasions and related device

1. A method of monitoring paging occasions for a user equipment (UE), the method comprising:

determining whether a paging configuration indicating at least two physical downlink control channel (PDCCH) monitoring occasions associated with a synchronization signal block (SSB) in a paging occasion (PO) is received from a base station (BS);

determining whether the UE is operated in an unlicensed spectrum;

receiving an indication in a short message in a first PDCCH monitoring occasion of the at least two PDCCH monitoring occasions when it is determined that the UE is operated in the unlicensed spectrum and the paging configuration indicating the at least two PDCCH monitoring occasions is received from the BS, the short message included in downlink control information (DCI) scrambled with a paging radio network temporary identifier (P-RNTI); and

stopping monitoring a second PDCCH monitoring occasion in the PO in response to receiving the indication.

2. The method of claim 1 , wherein the indication is set to a first value to indicate to the UE to stop monitoring the second PDCCH monitoring occasion in the PO.

3. The method of claim 1 , wherein the paging configuration is received by the UE via system information block type 1 (SIB1).

4. The method of claim 1 , further comprising:

determining whether the UE is operated in a licensed spectrum; and

ignoring the indication after determining that the UE is operated in the licensed spectrum or after determining that the UE is not operated in the unlicensed spectrum.

5. The method of claim 1 , further comprising ignoring the indication after determining that a second paging configuration received from the BS indicates one PDCCH monitoring occasion associated with the SSB or when no paging configuration is received from the BS.

6. The method of claim 1 , wherein the short message is received in a DCI format 1_0, and the indication is included in a third bit of the short message.

7. A user equipment (UE) for monitoring paging occasions, the UE comprising:

a processor configured to execute computer-executable instructions; and

a non-transitory computer-readable medium coupled to the processor and configured to store the computer-executable instructions, which when executed by the processor, cause the UE to:

determine whether a paging configuration indicating at least two physical downlink control channel (PDCCH) monitoring occasions associated with a synchronization signal block (SSB) in a paging occasion (PO) is received from a base station (BS);

determine whether the UE is operated in an unlicensed spectrum;

receive an indication in a short message in a first PDCCH monitoring occasion of the at least two PDCCH monitoring occasions when it is determined that the UE is operated in the unlicensed spectrum and the paging configuration indicating the at least two PDCCH monitoring occasions is received from the BS, the short message included in downlink control information (DCI) scrambled with a paging radio network temporary identifier (P-RNTI); and

stop monitoring a second PDCCH monitoring occasion in the PO in response to receiving the indication.

8. The UE of claim 7 , wherein the indication is set to a first value to indicate to the UE to stop monitoring the second PDCCH monitoring occasion in the PO.

9. The UE of claim 7 , wherein the paging configuration is received by the UE via system information block type 1 (SIB1).

10. The UE of claim 7 , wherein the computer-executable instructions when executed by the processor further cause the UE to:

determine whether the UE is operated in a licensed spectrum; and

ignore the indication after determining that the UE is operated in the licensed spectrum or after determining that the UE is not operated in the unlicensed spectrum.

11. The UE of claim 7 , wherein the computer-executable instructions when executed by the processor further cause the UE to:

ignore the indication after determining that a second paging configuration received from the BS indicates one PDCCH monitoring occasion associated with the SSB or when no paging configuration is received from the BS.

12. The UE of claim 7 , wherein the short message is received in a DCI format 1_0, and the indication is included in a third bit of the short message.

13. A method of configuring paging occasions for a base station (BS), the method comprising:

transmitting, to a user equipment (UE), a paging configuration indicating at least two physical downlink control channel (PDCCH) monitoring occasions associated with a synchronization signal block (SSB) in a paging occasion (PO); and

transmitting, to the UE, an indication in a short message included in downlink control information (DCI) scrambled with a paging radio network temporary identifier (P-RNTI) in a first PDCCH monitoring occasion of the at least two PDCCH monitoring occasions.

14. The method of claim 13 , wherein the indication is set to a first value to indicate to the UE to stop monitoring a second PDCCH monitoring occasion in the PO.

15. The method of claim 13 , wherein the paging configuration is transmitted by the BS via system information block type 1 (SIB1).

16. The method of claim 13 , wherein the short message is transmitted in a DCI format 1_0, and the indication is included in a third bit of the short message.

17. A base station (BS) for configuring paging occasions, the BS comprising:

a processor configured to execute computer-executable instructions; and

a non-transitory computer-readable medium coupled to the processor and configured to store the computer-executable instructions, which when executed by the processor, cause the UE to perform the method according to claim 13 .

18. The BS of claim 17 , wherein the indication is set to a first value to indicate to the UE to stop monitoring a second PDCCH monitoring occasion in the PO.

19. The BS of claim 17 , wherein the paging configuration is transmitted by the BS via system information block type 1 (SIB1).

20. The BS of claim 17 , wherein the short message is transmitted in a DCI format 1_0, and the indication is included in a third bit of the short message.
