Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, information in a groupcast message indicating a set of configurations to be deactivated. The UE may deactivate the set of configurations in accordance with the information. Numerous other aspects are described.

Claims (60)

1 . A user equipment (UE) for wireless communication, comprising one or more memories coupled to one or more processors, wherein the one or more processors are configured to cause the UE to:

receive, from a network entity, information in a groupcast message, the information indicating a set of configurations to be deactivated; and

deactivate the set of configurations in accordance with the information,

wherein the set of configurations are associated with a configuration state, and

wherein:

the configuration state is an active configuration state according to which the set of configurations are configured to be stored by the UE until signaling indicating to erase the set of configurations is received; or

the configuration state is an inactive configuration state according to which the set of configurations are configured to be stored by the UE until expiry of a timer, wherein the information indicates that the set of configurations are associated with the inactive configuration state; or

the configuration state is a first configuration state and wherein the one or more processors are further configured to cause the UE to erase a configuration of the set of configurations, in accordance with an idle configuration state, upon expiry of a timer associated with the first configuration state; or

the set of configurations are associated with the configuration state based at least in part on the UE having a capability for green networks or a device type associated with energy harvesting; or

the one or more processors are further configured to cause the UE to receive capability information indicating that the network entity supports the configuration state.

2 . The UE of claim 1 , wherein the groupcast message comprises at least one of a system information transmission or a group common physical downlink shared channel transmission.

3 . The UE of claim 1 , wherein the configuration state is the active configuration state according to which the set of configurations are configured to be stored by the UE until signaling indicating to erase the set of configurations is received.

4 . The UE of claim 1 , wherein the configuration state is the inactive configuration state according to which the set of configurations are configured to be stored by the UE until expiry of the timer, wherein the information indicates that the set of configurations are associated with the inactive configuration state.

5 . The UE of claim 1 , wherein the configuration state is the first configuration state and wherein the one or more processors are further configured to cause the UE to erase the configuration of the set of configurations, in accordance with the idle configuration state, upon expiry of the timer associated with the first configuration state.

6 . The UE of claim 1 , wherein the set of configurations are associated with the configuration state based at least in part on the UE having the capability for green networks or the device type associated with energy harvesting.

7 . The UE of claim 1 , wherein the one or more processors are further configured to cause the UE to receive capability information indicating that the network entity supports the configuration state.

8 . A network entity for wireless communication, comprising one or more memories coupled to one or more processors, wherein the one or more processors are configured to cause the network entity to:

transmit, associated with a user equipment (UE), information in a groupcast message, the information indicating a set of configurations to be deactivated; and

deactivate the set of configurations in accordance with the information,

wherein the set of configurations are associated with a configuration state, and

wherein:

the configuration state is an active configuration state according to which the set of configurations are configured to be stored by the UE until signaling indicating to erase the set of configurations is received; or

the configuration state is an inactive configuration state according to which the set of configurations are configured to be stored by the UE until expiry of a timer, wherein the information indicates that the set of configurations are associated with the inactive configuration state; or

the set of configurations are associated with the configuration state based at least in part on the UE having a capability for green networks or a device type associated with energy harvesting; or

wherein the one or more processors are further configured to cause the network entity to transmit capability information indicating that the network entity supports the configuration state.

9 . A method of wireless communication performed by a user equipment (UE), comprising:

receiving, from a network entity, information in a groupcast message, the information indicating a set of configurations to be deactivated; and

deactivating the set of configurations in accordance with the information,

wherein the set of configurations are associated with a configuration state, and

wherein:

the configuration state is an active configuration state according to which the set of configurations are configured to be stored by the UE until signaling indicating to erase the set of configurations is received; or

the configuration state is an inactive configuration state according to which the set of configurations are configured to be stored by the UE until expiry of a timer, wherein the information indicates that the set of configurations are associated with the inactive configuration state; or

the configuration state is a first configuration state and wherein the method further comprises erasing a configuration of the set of configurations, in accordance with an idle configuration state, upon expiry of a timer associated with the first configuration state; or

the set of configurations are associated with the configuration state based at least in part on the UE having a capability for green networks or a device type associated with energy harvesting; or

the method further comprises receiving capability information indicating that the network entity supports the configuration state.

10 . The method of claim 9 , wherein the groupcast message comprises at least one of a system information transmission or a group common physical downlink shared channel transmission.

11 . The method of claim 9 , wherein the configuration state is the active configuration state according to which the set of configurations are configured to be stored by the UE until signaling indicating to erase the set of configurations is received.

12 . The method of claim 9 , wherein the configuration state is the inactive configuration state according to which the set of configurations are configured to be stored by the UE until expiry of the timer, wherein the information indicates that the set of configurations are associated with the inactive configuration state.

13 . The method of claim 9 , wherein the configuration state is the first configuration state and wherein the method further comprises erasing the configuration of the set of configurations, in accordance with the idle configuration state, upon expiry of the timer associated with the first configuration state.
