A base station generates a notification with an instruction to perform a CG-SDT action and communicates the notification to a UE. The UE receives the instruction and performs the CG-SDT action to release CG-SDT resources allocated to the UE while the UE is in an inactive state. ## Claims ### Claim 1 A method performed by a user equipment (UE), the method comprising: receiving configuration information, the configuration information indicating a mapping of one or more actions pertaining to configured grant-small data transmission functionality of the UE to respective short message bit positions; receiving, while the UE is in an inactive state, a notification in a form of downlink control information with a short message field including one or more bits, the notification including an instruction indicating to perform an action of the one or more actions pertaining to the configured grant-small data transmission functionality of the UE; identifying, using the mapping of the one or more actions pertaining to the configured grant-small data transmission functionality of the UE to the respective short message bit positions, the action from at least one short message bit position of the one or more bits; and performing the action according to the instruction as pertaining to the configured grant-small data transmission functionality while the UE is in the inactive state. ### Claim 2 (depends on 1) The method of claim 1, wherein the downlink control information includes cyclical redundancy check information scrambled by a paging radio network temporary identifier. ### Claim 3 (depends on 1) The method of claim 1, wherein the downlink control information includes one or more of a device identifier for the UE or a group identifier for a group that includes the UE. ### Claim 4 (depends on 1) The method of claim 1, wherein the action comprises one or more of deactivating or deconfiguring a configured grant configuration of the UE. ### Claim 5 (depends on 1) The method of claim 1, wherein the action includes one or more of stopping a timing advance timer, expiring the timing advance timer, or invalidating the timing advance timer. ### Claim 6 (depends on 1) The method of claim 1, wherein the action comprises disabling the configured grant-small data transmission functionality of the UE. ### Claim 7 (depends on 1) The method of claim 1, wherein receiving the configuration information comprises: receiving control signaling activating the configured grant-small data transmission functionality of the UE, the control signaling comprising the configuration information. ### Claim 8 (depends on 1) The method of claim 1, further comprising: receiving, after performing the action, second configuration information, the second configuration information indicating a second mapping of the one or more actions pertaining to the configured grant-small data transmission functionality of the UE to second respective short message bit positions. ### Claim 9 A user equipment (UE) for wireless communication, comprising: at least one memory; and at least one processor coupled with the at least one memory and configured to cause the UE to: receive configuration information, the configuration information indicating a mapping of one or more actions pertaining to configured grant-small data transmission functionality of the UE to respective short message bit positions; receive, while the UE is in an inactive state, a notification in a form of downlink control information with a short message field including one or more bits, the notification including an instruction indicating to perform an action of the one or more actions pertaining to the configured grant-small data transmission functionality of the UE; identify, using the mapping of the one or more actions pertaining to the configured grant-small data transmission functionality of the UE to the respective short message bit positions, the action from at least one short message bit position of the one or more bits; and perform the action according to the instruction as pertaining to the configured grant-small data transmission functionality while the UE is in the inactive state. ### Claim 10 (depends on 9) The UE of claim 9, wherein the downlink control information includes cyclical redundancy check information scrambled by a paging radio network temporary identifier. ### Claim 11 (depends on 9) The UE of claim 9, wherein to perform the action, the at least one processor is configured to cause the UE to: determine that a small data transmission is to be transmitted by the UE; and implement a random access channel procedure for the small data transmission to determine that the configured grant-small data transmission functionality is at least temporarily unavailable. ### Claim 12 (depends on 9) The UE of claim 9, wherein to receive the configuration information, the at least one processor is configured to cause the UE to: receive control signaling activating the configured grant-small data transmission functionality of the UE, the control signaling comprising the configuration information. ### Claim 13 A base station for wireless communication, comprising: at least one memory; and at least one processor coupled with the at least one memory and configured to cause the base station to: generate configuration information, the configuration information indicating a mapping one or more actions pertaining to configured grant-small data transmission functionality of a user equipment (UE) to respective short message bit positions; transmit the configuration information for receipt by the UE; generate a notification in a form of downlink control information with a short message field including one or more bits, the notification including an instruction indicating to perform an action of the one or more actions pertaining to the configured grant-small data transmission functionality of the UE while the UE is in an inactive state; and transmit the notification for receipt by the UE while the UE is in the inactive state. ### Claim 14 (depends on 13) The base station of claim 13, wherein the downlink control information includes cyclical redundancy check information scrambled by a paging radio network temporary identifier. ### Claim 15 (depends on 13) The base station of claim 13, wherein the downlink control information includes one or more of a device identifier for the UE or a group identifier for a group that includes the UE. ### Claim 16 (depends on 13) The base station of claim 13, wherein the action comprises one or more of to deactivate or deconfigure a configured grant configuration of the UE. ### Claim 17 (depends on 13) The base station of claim 13, wherein the action includes one or more of to stop a timing advance timer, expire the timing advance timer, or invalidate the timing advance timer. ### Claim 18 (depends on 13) The base station of claim 13, wherein the action comprises to disable the configured grant-small data transmission functionality of the UE. ### Claim 19 (depends on 13) The base station of claim 13, wherein the base station includes a component of a radio access network, the at least one processor configured to cause the base station to generate the notification independent of an instruction from a core network. ### Claim 20 A processor for wireless communication, comprising: at least one controller coupled with at least one memory and configured to cause the processor to: receive configuration information, the configuration information indicating a mapping of one or more actions pertaining to configured grant-small data transmission functionality of the processor to respective short message bit positions; receive a notification in a form of downlink control information a short message field including one or more bits, the notification including an instruction indicating to perform an action of the one or more actions pertaining to the configured grant-small data transmission functionality of a device while the device is in an inactive state; identify, using the mapping of the one or more actions pertaining to the configured grant-small data transmission functionality of the processor to the respective short message bit positions, the action from at least one short message bit position of the one or more bits; and perform the action according to the instruction as pertaining to the configured grant-small data transmission functionality while the processor is in the inactive state.
