Abstract
A method performed by a UE. The method includes receiving from a MN a first RRC reconfiguration message (RRCReconfiguration). The RRCReconfiguration message comprises: i) a second RRC reconfiguration message, RRCReconfiguration***, generated by an S-SN, wherein the RRCReconfiguration*** message comprises a measurement configuration; and ii) a conditional reconfiguration IE (e.g., ConditionalReconfiguration IE) generated by the MN, wherein the conditional reconfiguration IE contains at least a first measurement ID that the MN obtained from S-SN, and the first measurement ID is associated with the measurement configuration.

A method performed a master node (MN), the method comprising:
- receiving from a source secondary node (S-SN) a first radio resource control (RRC) configuration message, wherein the first RRC reconfiguration message comprises a measurement configuration;
- providing to a user equipment (UE) a second RRC reconfiguration message, wherein the second RRC reconfiguration message comprises:
- i) the first RRC reconfiguration message;
- and
- ii) a conditional reconfiguration information element (IE), wherein the conditional reconfiguration IE contains at least a first measurement identifier (ID) received from the S-SN, and the first measurement ID is associated with the measurement configuration;
- providing to the UE a third RRC reconfiguration message that was generated by a target secondary node (T-SN), wherein the third RRC reconfiguration message includes random access procedure information to be used by the UE in performing a random access procedure for establishing a connection with the T-SN;
- and
- receiving from the UE a second RRC reconfiguration complete message responsive to the first RRC reconfiguration message.
A method performed by a user equipment (UE), the method comprising:
- receiving from a master node (MN) a first radio resource control (RRC) reconfiguration message, wherein the first RRC reconfiguration message comprises:
- i) a second RRC reconfiguration message generated by a source secondary node, wherein the second RRC reconfiguration message comprises a measurement configuration;
- and
- ii) a conditional reconfiguration information element (IE), wherein the conditional reconfiguration IE contains at least a first measurement identifier (ID) from the source secondary node (S-SN), and the first measurement ID is associated with the measurement configuration;
- obtaining a third RRC reconfiguration message that was generated by a target secondary node (T-SN);
- transmitting to the MN a second RRC reconfiguration complete message responsive to the second RRC reconfiguration message;
- detecting that a condition indicated in the conditional reconfiguration IE is satisfied;
- and
- as a result of detecting that the condition is satisfied, using information included in the third RRC reconfiguration message to perform a random access procedure to establish a connection with the T-SN.
A user equipment (UE), the UE comprising:
- memory;
- and
- processing circuitry, wherein the UE is operable to perform a method comprising:
- receiving from a master node (MN) a first radio resource control (RRC) reconfiguration message, wherein the first RRC reconfiguration message comprises:
- i) a second RRC reconfiguration message generated by a source secondary node, wherein the second RRC reconfiguration message comprises a measurement configuration;
- and
- ii) a conditional reconfiguration information element (IE), wherein the conditional reconfiguration IE contains at least a first measurement identifier (ID) from the source secondary node (S-SN), and the first measurement ID is associated with the measurement configuration;
- obtaining a third RRC reconfiguration message that was generated by a target secondary node (T-SN);
- transmitting to the MN a second RRC reconfiguration complete message responsive to the second RRC reconfiguration message;
- detecting that a condition indicated in the conditional reconfiguration IE is satisfied;
- and
- as a result of detecting that the condition is satisfied, using information included in the third RRC reconfiguration message to perform a random access procedure to establish a connection with the T-SN.
