The UE receives an SPS command to activate or deactivate each of multiple SPS resource configurations among the N SPS resource configurations. The UE performs downlink reception or uplink transmission in an SPS resource corresponding to an SPS resource configuration among activated SPS resource configurations. The SPS command includes information indicating each of the multiple SPS resource configurations and information indicating whether a corresponding SPS resource configuration is activated or deactivated. ## Claims ### Claim 1 A method for receiving, by a user equipment (UE), downlink signals, the method comprising: receiving, by the UE, semi-persistent scheduling (SPS) configuration information on N SPS resource configurations, where N is an integer larger than 1; receiving, by the UE, an SPS command to activate or deactivate each of multiple SPS resource configurations among the N SPS resource configurations; transmitting, by the UE, SPS status information on the N SPS resource configurations in response to the SPS command; and performing, by the UE, downlink reception or uplink transmission in an SPS resource corresponding to an SPS resource configuration among activated SPS resource configurations, wherein the SPS command includes information indicating each of the multiple SPS resource configurations and information indicating whether a corresponding SPS resource configuration is activated or deactivated, wherein the SPS status information includes information on whether the N SPS resource configurations are active or not in the UE, respectively, and wherein the SPS status information is transmitted on a first SPS resource of a union of the activated SPS resource configurations. ### Claim 2 (depends on 1) The method according to claim 1, wherein the SPS command includes a bitmap including N bits respectively corresponding to the N SPS resource configurations, wherein each bit of the N bits is corresponding to an index of each of the N SPS resource configurations and indicates whether an SPS resource configuration corresponding to a bit of the N bits is activated or deactivated. ### Claim 3 (depends on 1) The method according to claim 1, wherein the SPS command includes an index of each of the multiple SPS resource configuration and an indicator indicating whether an SPS resource configuration corresponding to the index is activated or deactivated. ### Claim 4 (depends on 1) The method according to claim 1, wherein the SPS command is received via a medium access control (MAC) signaling. ### Claim 5 (depends on 2) The method according to claim 2, further comprising: activating an SPS resource configuration corresponding to a bit set to a first value among the N bits; and deactivating an SPS resource configuration corresponding to a bit set to a second value among the N bits. ### Claim 6 (depends on 3) The method according to claim 3, further comprising: maintaining an activated or deactivated state of an SPS resource configuration not indicated by the SPS command. ### Claim 7 A user equipment (UE) for receiving downlink signals, the UE comprising: a radio frequency (RF) unit; and a processor configured to control the RF unit, the processor configured to: control the RF unit to receive semi-persistent scheduling (SPS) configuration information on N SPS resource configurations, where N is an integer larger than 1; control the RF unit to receive an SPS command to activate or deactivate each of multiple SPS resource configurations among the N SPS resource configurations; control the RF unit to transmit SPS status information on the N SPS resource configurations in response to the SPS command; and control the RF unit to perform downlink reception or uplink transmission in an SPS resource corresponding to an SPS resource configuration among activated SPS resource configurations, wherein the SPS command includes information indicating each of the multiple SPS resource configurations and information indicating whether a corresponding SPS resource configuration is activated or deactivated, wherein the SPS status information includes information on whether the N SPS resource configurations are active or not in the UE, respectively, and wherein the SPS status information is transmitted on a first SPS resource of a union of the activated SPS resource configurations. ### Claim 8 (depends on 7) The UE according to claim 7, wherein the SPS command includes a bitmap including N bits respectively corresponding to the N SPS resource configurations, wherein each bit of the N bits is corresponding to an index of each of the N SPS resource configurations and indicates whether an SPS resource configuration corresponding to a bit of the N bits is activated or deactivated. ### Claim 9 (depends on 7) The UE according to claim 7, wherein the SPS command includes an index of each of the multiple SPS resource configuration and an indicator indicating whether an SPS resource configuration corresponding to the index is activated or deactivated. ### Claim 10 (depends on 7) The UE according to claim 7, wherein the SPS command is received via a medium access control (MAC) signaling. ### Claim 11 (depends on 8) The UE according to claim 8, wherein the processor is configured to: activate an SPS resource configuration corresponding to a bit set to a first value among the N bits; and deactivate an SPS resource configuration corresponding to a bit set to a second value among the N bits. ### Claim 12 (depends on 9) The UE according to claim 9, wherein the processor is configured to: maintain an activated or deactivated state of an SPS resource configuration not indicated by the SPS command.
