Abstract

A method for controlling PDCCH monitoring is provided in the disclosure. The method may include: obtaining first signaling; and determining whether a secondary cell is in a dormant state or a non-dormant state according to the first signaling.

Claims (70)

1 . A method for controlling physical downlink control channel (PDCCH) monitoring, comprising:

determining whether to stop monitoring PDCCHs corresponding to a primary cell (PCell) or a primary secondary cell (PSCell) according to the third signaling;

determining to stop monitoring the PDCCHs corresponding to the PCell or the PSCell, if the third signaling is in a second preset pattern; and

determining a first duration according to the third signaling, if determining to stop monitoring the PDCCHs corresponding to the PCell or the PSCell.

2 . The method of claim 1 , further comprising:

acquiring second signaling; and

determining whether to stop monitoring the PDCCHs corresponding to the PCell or the PSCell according to the second signaling.

3 . The method of claim 2 , wherein the second signaling is a bit in the bitmap, and determining whether to stop monitoring the PDCCHs corresponding to the PCell or the PSCell according to the second signaling comprises:

determining to stop monitoring the PDCCHs corresponding to the PCell or the PSCell, if the bit in the bitmap is “0”; or

determining to monitor the PDCCHs corresponding to the PCell or the PSCell, if the bit in the bitmap is “1”.

4 . The method of claim 2 , further comprising:

determining to stop monitoring the PDCCHs corresponding to the PCell or the PSCell, if all bits in the bitmap are “0”; or

determining to monitor the PDCCHs corresponding to the PCell or the PSCell, if all bits in the bitmap are “1”.

5 . The method of claim 2 , wherein stopping monitoring the PDCCHs corresponding to the PCell or the PSCell comprises:

stopping at least one of a drx-onDurationTimer or a drx-InactivityTimer.

6 . The method of claim 2 , wherein stopping monitoring the PDCCHs corresponding to the PCell or the PSCell comprises at least one of:

stopping monitoring the PDCCHs corresponding to the PCell or the PSCell during DRX active time; or

stopping monitoring the PDCCHs corresponding to the PCell or the PSCell during DRX active time indicated by at least one of a drx-onDurationTimer or a drx-InactivityTimer.

7 . The method of claim 2 , wherein stopping monitoring the PDCCHs corresponding to the PCell or the PSCell comprises at least one of:

switching to a dormant BWP for the PCell or the PSCell during DRX active time;

using a dormant BWP as an active BWP for the PCell or the PSCell during DRX active time;

switching to a dormant BWP for the PCell or the PSCell during DRX active time indicated by at least one of a drx-onDurationTimer or a drx-InactivityTimer; or

using a dormant BWP as an active BWP for the PCell or the PSCell during DRX active time indicated by at least one of a drx-onDurationTimer a drx-InactivityTimer.

8 . The method of claim 1 , wherein the first duration is an intersection between a duration provided by a higher layer parameter and DRX active time, or an intersection between a duration provided by a higher layer parameter and DRX active time indicated by at least one of a drx-onDurationTimer or a drx-InactivityTimer.

9 . The method of claim 1 , wherein stopping monitoring the PDCCHs corresponding to the PCell or the PSCell comprises at least one of:

stopping monitoring the PDCCHs corresponding to the PCell or the PSCell during the first duration;

stopping monitoring the PDCCHs corresponding to the PCell or the PSCell during an intersection between the first duration and DRX active time;

stopping monitoring the PDCCHs corresponding to the PCell or the PSCell during an intersection between the first duration and DRX active time indicated by at least one of a drx-onDurationTimer or a drx-InactivityTimer;

determining to stop monitoring the PDCCHs corresponding to the PCell or the PSCell, if the fourth signaling is value “0”; or

determining to monitor the PDCCHs corresponding to the PCell or the PSCell, if the fourth signaling is value “1”.

13 . The method of claim 10 , wherein the second duration is an intersection between a duration provided by a higher layer parameter and DRX active time, or an intersection between a duration provided by a higher layer parameter and DRX active time indicated by at least one of a drx-onDurationTimer or a drx-InactivityTimer.

14 . The method of claim 10 , wherein stopping monitoring the PDCCHs corresponding to the PCell or the PSCell comprises at least one of:

stopping monitoring the PDCCHs corresponding to the PCell or the PSCell during the second duration;
