Abstract
Certain aspects of the present disclosure relate to methods and apparatus for signaling to and/or from a UE in an inactive state.
Claims25
A method for wireless communications by a user equipment (UE), comprising:
- receiving signaling of a configuration to establish a signaling radio bearer (SRB) with at least one of a first link to a first network entity and a second link to a second network entity;
- transitioning to an inactive state where context of the UE in the network is maintained at the UE and at least the first network entity;
- and
- communicating with the network using the SRB while in the inactive state
- wherein the UE applies the configuration to access the network via the SRB when moving to the second network entity;
- and
- wherein communicating with the network comprises performing a radio access network (RAN) notification area (RNA) update procedure using the split bearer.

A method for wireless communications by a network entity, comprising:
- signaling, to a user equipment (UE), a configuration to establish a split signaling radio bearer (SRB) with a first link to the network entity and a second link to another network entity;
- transitioning the UE to an inactive state where context of the UE in the network is maintained at the UE and at least the network entity;
- and
- communicating with the UE via the SRB while the UE is in the inactive state
- wherein:
- the UE supports dual-connectivity;
- the SRB comprises a split SRB with a first link to the network entity and a second link to the other network entity;
- the network entity comprises a master node (MN);
- the other network entity comprises a secondary node (SN);
- the MN configures the other network entity to act as an SN and releases another network entity previously acting as an SN to the UE, and
- the UE applies the configuration to access the network via the SRB when moving to the other network entity.
8 more elements
A method for wireless communications by a network entity, comprising:
- receiving a message from a user equipment (UE) in an inactive state via a split signaling radio bearer (SRB) with a first link to the network entity and a second link to another network entity;
- and
- forwarding the message to the second network entity wherein:
- the other network entity comprises an anchor base station that signaled the configuration to the UE;
- and
- the network entity comprises a base station the UE is using to access the network.
