Abstract

Provided are a monitoring method/device for monitoring a downlink control channel of a terminal in a wireless communication system, and a downlink control channel transmission method/device corresponding to the monitoring method/device. A PS-PDCCH including power saving information is monitored in a DRX-on period, and when the PS-PDCCH is detected, a PDCCH is monitored on the basis of same. The PS-PDCCH may provide notification about a specific search space set among a plurality of search space sets, and exceptionally skip PDCCH monitoring for the specific search space set.

Claims (28)

1 . A method comprising:

receiving, by a user equipment (UE), a radio resource control (RRC) parameter for a set of durations;

receiving, by the UE, downlink control information (DCI); and

performing, by the UE, an operation based on the RRC parameter and the DCI,

wherein the DCI includes a field for a physical downlink control channel (PDCCH) monitoring adaptation,

wherein based on the field informing the UE of skipping PDCCH monitoring for a specific duration, the UE skips PDCCH monitoring for the specific duration, and

wherein the specific duration is informed based on a value of the field among the set of durations.

2 . The method of claim 1 , wherein the UE skips PDCCH monitoring in a specific search space sets.

3 . The method of claim 1 , wherein the DCI is received through a PDCCH.

4 . The method of claim 1 , wherein the specific duration is provided by a network.

5 . The method of claim 1 , wherein, based on that the field informs the UE of no skipping in PDCCH monitoring, the UE performs PDCCH monitoring.

6 . The method of claim 5 , wherein the UE monitors a set of PDCCH candidates in one or more control resource sets (CORESETs).

7 . A user equipment (UE) comprising:

at least one transceiver;

at least one memory; and

at least one processor operably connectable to the at least one transceiver and the at least one memory,

wherein the at least one memory stores instructions that, based on being executed by the at least one processor, cause the at least one processor to perform operations comprising:

receiving a radio resource control (RRC) parameter for a set of durations;

receiving downlink control information (DCI); and

performing an operation based on the RRC parameter and the DCI,

wherein the DCI includes a field for a physical downlink control channel (PDCCH) monitoring adaptation,

wherein based on the field informing the UE of skipping PDCCH monitoring for a specific duration, the UE skips PDCCH monitoring for the specific duration, and

wherein the specific duration is informed based on a value of the field among the set of durations.

8 . The UE of claim 7 , wherein the UE skips PDCCH monitoring in a specific search space sets.

9 . The UE of claim 7 , wherein the DCI is received through a PDCCH.

10 . The UE of claim 7 , wherein the specific duration is provided by a network.

11 . The UE of claim 7 , wherein, based on that the field informs the UE of no skipping in PDCCH monitoring, the UE performs PDCCH monitoring.

12 . The UE of claim 11 , wherein the UE monitors a set of PDCCH candidates in one or more control resource sets (CORESETs).
