Method for monitoring paging and apparatus using the same
A method for monitoring paging is provided. The method is performed by a user equipment (UE) and includes actions of receiving a first Physical Downlink Control Channel (PDCCH) addressed to a first Radio Network Temporary Identifier (RNTI), and stopping monitoring a second PDCCH addressed to a second RNTI if the first PDCCH includes a paging stop indicator, where the second RNTI is the same as the first RNTI.
1. A user equipment (UE), comprising:
one or more non-transitory computer-readable media storing computer-executable instructions; and
at least one processor coupled to the one or more non-transitory computer-readable media, and configured to execute the computer-executable instructions to:
receive a first Physical Downlink Control Channel (PDCCH) addressed to a Radio Network Temporary Identifier (RNTI); and
stop monitoring a second PDCCH addressed to the same RNTI if the first PDCCH includes a paging stop indicator.
2. The UE of claim 1 , wherein:
the UE is configured with a plurality of PDCCH monitoring occasions for paging in a Paging Occasion (PO) within a Discontinuous Reception (DRX) cycle, and
the plurality of PDCCH monitoring occasions for paging includes a first PDCCH monitoring occasion for the first PDCCH and a second PDCCH monitoring occasion for the second PDCCH.
3. The UE of claim 2 , wherein the at least one processor is further configured to execute the computer-executable instructions to:
receive, from a cell, at least one configuration in system information; and
determine the plurality of PDCCH monitoring occasions for paging according to the at least one configuration.
4. The UE of claim 3 , wherein the at least one processor is further configured to execute the computer-executable instructions to:
determine a number of the plurality of PDCCH monitoring occasions for paging in the PO based on the at least one configuration.
5. The UE of claim 3 , wherein the at least one configuration includes a Paging Control Channel (PCCH) configuration.
6. The UE of claim 2 , wherein the second PDCCH monitoring occasion is subsequent to the first PDCCH monitoring occasion in time domain.
7. The UE of claim 1 , wherein the at least one processor is further configured to execute the computer-executable instructions to:
stop monitoring the second PDCCH if the UE does not successfully decode the first PDCCH.
8. The UE of claim 1 , wherein the paging stop indicator is contained in paging Downlink Control Information (DCI).
9. The UE of claim 1 , wherein the paging stop indicator is contained in a Radio Resource Control (RRC) message.
10. The UE of claim 1 , wherein the first PDCCH and the second PDCCH are associated with a same Synchronization Signal/Physical Broadcast Channel Block (SSB).
11. A method performed by a user equipment (UE), the method comprising:
receiving a first Physical Downlink Control Channel (PDCCH) addressed to a first Radio Network Temporary Identifier (RNTI); and
stopping monitoring a second PDCCH addressed to the same RNTI if the first PDCCH includes a paging stop indicator.
12. The method of claim 11 , wherein:
the UE is configured with a plurality of PDCCH monitoring occasions for paging in a Paging Occasion (PO) within a Discontinuous Reception (DRX) cycle, and
the plurality of PDCCH monitoring occasions for paging includes a first PDCCH monitoring occasion for the first PDCCH and a second PDCCH monitoring occasion for the second PDCCH.
13. The method of claim 12 , further comprising:
receiving, from a cell, at least one configuration in system information; and
determining the plurality of PDCCH monitoring occasions for paging according to the at least one configuration.
14. The method of claim 13 , further comprising:
determining a number of the plurality of PDCCH monitoring occasions for paging in the PO based on the at least one configuration.
15. The method of claim 13 , wherein the at least one configuration includes a Paging Control Channel (PCCH) configuration.
16. The method of claim 12 , wherein the second PDCCH monitoring occasion is subsequent to the first PDCCH monitoring occasion in time domain.
17. The method of claim 11 , further comprising:
stopping monitoring the second PDCCH if the UE does not successfully decode the first PDCCH.
18. The method of claim 11 , wherein the paging stop indicator is contained in paging Downlink Control Information (DCI).
19. The method of claim 11 , wherein the paging stop indicator is contained in a Radio Resource Control (RRC) message.
20. The method of claim 11 , wherein the first PDCCH and the second PDCCH are associated with a same Synchronization Signal/Physical Broadcast Channel Block (SSB).
