Techniques for indicating full configuration to a secondary node in dual connectivity

Abstract:

Methods, systems, and devices for wireless communications are described. In some systems, a master node (MN) may determine to reconfigure a user equipment (UE) from an existing configuration to a full configuration for a dual connectivity (DC) mode. To perform the reconfiguration, the MN may transmit a signal (e.g., a modification request message) indicating the full configuration to a secondary node (SN). The SN may identify the full configuration reconfiguration triggered at the MN based on the signal. The SN may transmit an acknowledgment message to the MN including a secondary cell group (SCG) configuration for the SN complying with the full configuration. The MN may indicate this SCG configuration as part of the full configuration to the UE (e.g., in a radio resource control (RRC) connection reconfiguration message). The UE may perform a reconfiguration process and communicate with the MN and the SN according to the full configuration.
