    Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify a relay pairing between a user equipment (UE) and a relay UE. The base station may additionally identify a configuration of the relay UE based on a handover decision associated with the relay pairing. The base station may indicate, to the UE, the configuration of the relay UE, an identifier of the relay UE, and that the UE is to switch to a sidelink communications link with the relay UE. The UE may then establish the sidelink communications link with the relay UE and may indicate, to the relay UE, that the sidelink communication link is for a handover associated with the relay pairing. Based on receiving the indication that the sidelink communication link is for the handover associated with the relay pairing, the relay UE may perform a connection setup procedure with the base station.

    Abstract: The user equipment (UE) may evaluate link qualities between the UE and target primary secondary cell group (SCG) cells (PSCells) respectively associated with target secondary nodes, select a target PSCell from the target PSCells based on the link qualities and execution conditions respectively associated with the target PSCells of the target secondary nodes, initiate a conditional execution procedure to connect to a target secondary node corresponding to the selected target PSCell, and responsive to a source SCG state corresponding to a source PSCell of a source secondary node being a deactivated state, perform either: changing an SCG state at the UE to an activated state and performing a random access channel (RACH) procedure on the selected target PSCell to perform the conditional execution procedure to connect to the selected target PSCell, or maintaining the SCG state at the UE as the deactivated state without performing a RACH procedure.

    Abstract: The present disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for robust compatibility mode communication. A user equipment may determine whether a robust compatibility mode (RCM) is supported between the UE and the base station. The UE also may establish a RCM connection with the base station when the RCM is supported between the UE and the base station. The UE also may receive, from the base station, through the RCM connection, a configuration associated with the RCM. The UE also may update a behavior of the UE for a current situation of the UE based on the configuration. The UE also may transmit, to the base station, a request to access a wireless network with the updated behavior of the UE.
