INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract The present disclosure proposes monitoring of a power saving signal and a physical downlink control channel. ## Claims ### Claim 1 A method for performing physical downlink control channel (PDCCH) monitoring in a wireless communication system, the method performed by a user equipment (UE) and comprising: receiving a power saving signal configuration from a network; monitoring the power saving signal at more than one monitoring occasion before a next on-duration based on the power saving signal configuration, wherein the power saving signal is downlink control information (DCI) on a physical downlink control channel (PDCCH), and wherein the DCI is related to a power saving radio network temporary identity (PS-RNTI); and based on the power saving signal being detected, performing the PDCCH monitoring at the next on-duration, wherein the power saving signal includes configuration information related to the PDCCH monitoring, wherein the configuration information includes a search space set configuration including a monitoring period related to a search space set in which the PDCCH monitoring is performed, a monitoring pattern related to the PDCCH monitoring, a duration, an aggregation level (AL), monitored DCI and a number of candidates, and wherein the PDCCH monitoring is performed in the search space set based on the search space set configuration. ### Claim 2 (depends on 1) The method of claim 1, wherein the configuration information further includes at least one of a bandwidth part (BWP) in which the PDCCH monitoring is performed, or an application timing of the configuration information. ### Claim 3 (depends on 2) The method of claim 2, wherein the BWP is larger than a BWP in which the power saving signal is monitored. ### Claim 4 (depends on 2) The method of claim 2, wherein the application timing of the configuration information is determined based on a capability of the UE. ### Claim 5 (depends on 2) The method of claim 2, wherein the application timing of the configuration information is a timing at which a feedback signal for the power saving signal is transmitted to a network. ### Claim 6 (depends on 5) The method of claim 5, wherein the feedback signal is hybrid automatic repeat request acknowledgement/negative-acknowledgement (HARQ ACK/NACK). ### Claim 7 (depends on 2) The method of claim 2, wherein the application timing of the configuration information is determined based on a numerology. ### Claim 8 (depends on 1) The method of claim 1, wherein the search space set is all or part of a plurality of search space sets configured for the UE. ### Claim 9 (depends on 1) The method of claim 1, wherein the power saving signal configuration includes at least one of a period or a BWP in which the power saving signal is monitored. ### Claim 10 (depends on 1) The method of claim 1, wherein a period in which the power saving signal is monitored is configured independently per BWP. ### Claim 11 A user equipment (UE) comprising: at least one memory to store instructions; at least one transceiver; and at least one processor to connect the at least one memory and the at least one transceiver, wherein the at least one processor executes the instructions to: receive a power saving signal configuration from a network; monitor the power saving signal at more than one monitoring occasion before a next on-duration based on the power saving signal configuration, wherein the power saving signal is downlink control information (DCI) on a physical downlink control channel (PDCCH), and wherein the DCI is related to a power saving radio network temporary identity (PS-RNTI); and based on the power saving signal being detected, perform a physical downlink control channel (PDCCH) monitoring at the next on-duration, wherein the power saving signal includes configuration information related to the PDCCH monitoring, wherein the configuration information includes a search space set configuration including a monitoring period related to a search space set in which the PDCCH monitoring is performed, a monitoring pattern related to the PDCCH monitoring, a duration, an aggregation level (AL), monitored DCI and a number of candidates, and wherein the PDCCH monitoring is performed in the search space set based on the search space set configuration. ### Claim 12 (depends on 11) The UE of claim 11, wherein the configuration information further includes at least one of a bandwidth part (BWP) in which the PDCCH monitoring is performed, or an application timing of the configuration information. ### Claim 13 (depends on 12) The UE of claim 12, wherein the BWP is larger than a BWP in which the power saving signal is monitored. ### Claim 14 (depends on 12) The UE of claim 12, wherein the application timing of the configuration information is determined based on a capability of the UE. ### Claim 15 (depends on 12) The UE of claim 12, wherein the application timing of the configuration information is a timing at which a feedback signal for the power saving signal is transmitted to a network. ### Claim 16 (depends on 15) The UE of claim 15, wherein the feedback signal is hybrid automatic repeat request acknowledgement/negative-acknowledgement (HARQ ACK/NACK). ### Claim 17 (depends on 12) The UE of claim 12, wherein the application timing of the configuration information is determined based on a numerology. ### Claim 18 (depends on 11) The UE of claim 11, wherein the search space set is all or part of a plurality of search space sets configured for the UE. ### Claim 19 (depends on 11) The UE of claim 11, wherein the power saving signal configuration includes at least one of a period or a BWP in which the power saving signal is monitored. ### Claim 20 (depends on 11) The UE of claim 11, wherein a period in which the power saving signal is monitored is configured independently per BWP.
