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 having computer-executable instructions embodied thereon; 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 first Radio Network Temporary Identifier (RNTI);
stop monitoring a second PDCCH addressed to a second RNTI if the first PDCCH includes a paging stop indicator;
receive at least one configuration in system information from a cell; and
determine a plurality of PDCCH monitoring occasions for paging in a Paging Occasion (PO) within a Discontinuous Reception (DRX) cycle according to the at least one configuration,
wherein:
the second RNTI is the same as the first RNTI,
the plurality of PDCCH monitoring occasions for the paging includes a first PDCCH monitoring occasion for the first PDCCH and a second PDCCH monitoring occasion for the second PDCCH, and
the at least one configuration comprises:
a first parameter indicating a number of transmitted Synchronization Signal/Physical Broadcast Channel Blocks (SSBs) for each beam sweeping round in the PO, and
a second parameter indicating a total number of beam sweeping rounds in the PO.
2. The UE of claim 1 , wherein the at least one processor is further configured to execute the computer-executable instructions to:
determine a total number of PDCCH monitoring occasions in the plurality of PDCCH monitoring occasions for the paging in the PO based on a product of the first parameter and the second parameter.
3. The UE of claim 1 , wherein the at least one configuration further comprises a Paging Control Channel (PCCH) configuration.
4. The UE of claim 1 , wherein the second PDCCH monitoring occasion is subsequent to the first PDCCH monitoring occasion in a time domain.
5. 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.
6. The UE of claim 1 , wherein the paging stop indicator is contained in paging Downlink Control Information (DCI).
7. The UE of claim 1 , wherein the paging stop indicator is contained in a Radio Resource Control (RRC) message.
8. The UE of claim 1 , wherein the first PDCCH and the second PDCCH are associated with a same SSB.
9. 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);
stopping monitoring a second PDCCH addressed to a second RNTI if the first PDCCH includes a paging stop indicator;
receiving at least one configuration in system information from a cell; and
determining a plurality of PDCCH monitoring occasions for paging in a Paging Occasion (PO) within a Discontinuous Reception (DRX) cycle according to the at least one configuration,
wherein:
the second RNTI is the same as the first RNTI,
the plurality of PDCCH monitoring occasions for the paging includes a first PDCCH monitoring occasion for the first PDCCH and a second PDCCH monitoring occasion for the second PDCCH, and
the at least one configuration comprises:
a first parameter indicating a number of transmitted Synchronization Signal/Physical Broadcast Channel Blocks (SSBs) for each beam sweeping round in the PO, and
a second parameter indicating a total number of beam sweeping rounds in the PO.
10. The method of claim 9 , further comprising:
determining a total number of PDCCH monitoring occasions in the plurality of PDCCH monitoring occasions for the paging in the PO based on a product of the first parameter and the second parameter.
11. The method of claim 9 , wherein the at least one configuration further comprises a Paging Control Channel (PCCH) configuration.
12. The method of claim 9 , wherein the second PDCCH monitoring occasion is subsequent to the first PDCCH monitoring occasion in a time domain.
13. The method of claim 9 , further comprising:
stopping monitoring the second PDCCH if the UE does not successfully decode the first PDCCH.
14. The method of claim 9 , wherein the paging stop indicator is contained in paging Downlink Control Information (DCI).
15. The method of claim 9 , wherein the paging stop indicator is contained in a Radio Resource Control (RRC) message.
16. The method of claim 9 , wherein the first PDCCH and the second PDCCH are associated with a same SSB.
