1

Step 1 of Generic procedure for bringing the UE in RRC_CONNECTED state with connectivity NR as specified in Table 4.5.4.2-3 is performed.

2

Check: Does the UE transmit an RRCSetupRequest message on the cell specified in the test case?

3-8

Steps 3-8 of Generic procedure for bringing the UE in RRC_CONNECTED state with connectivity NR as specified in Table 4.5.4.2-3 are performed.

EXCEPTION: Step 9a1 describes a step sequence depending on procedure parameters; the "lower case letter" identifies a step sequence that take place if a procedure parameter has a particular value

9a1

IF ‘connected without release‘ is not present THEN the SS transmits an RRCRelease message to release RRC connection and move the UE to RRC_IDLE.
