Abstract
Embodiments herein achieve a method for handling a RLF in a wireless communication system by a UE. The method includes detecting the RLF at the UE associated with a first cell that is associated with a first RAT. Further, the method includes selecting a second cell, associated with a second RAT, by performing a cell selection procedure. Further, the method includes detecting that a 5GC is connected. Further, the method includes determining whether a timer is running in the UE. Further, the method includes performing an IRAT RRC re-establishment procedure on the second cell when the RLF is occurred on the first cell associated with the first RAT in response to determining that the timer is running in the UE.
Claims15
A method for operating a user equipment (UE) for handling a radio link failure (RLF) in a wireless communication system, comprising:
- detecting the RLF at the UE associated with a first cell in the wireless communication system, wherein the first cell is associated with a first Radio Access Technology (RAT);
- selecting a second cell in the wireless communication system by performing a cell selection procedure in response to detecting the RLF at the UE associated with the first cell in the wireless communication system, wherein the second cell is associated with a second RAT;
- detecting that a fifth generation core (5GC) is connected;
- determining that a timer is running, in the UE, on the second RAT;
- and
- in response to determining that the timer is running in the UE on the second RAT, performing an Inter Radio Access Technology (IRAT) Radio Resource Control (RRC) re-establishment procedure on the second cell when the RLF is occurred on the first cell associated with the first RAT.
A User Equipment (UE) for handling a radio link failure (RLF) in a wireless communication system, comprising:
- a transceiver;
- and
- at least one processor, coupled with the transceiver, configured to:
- detect the RLF at the UE associated with a first cell in the wireless communication system, wherein the first cell is associated with a first RAT;
- select a second cell in the wireless communication system by performing a cell selection procedure in response to detecting the RLF at the UE associated with the first cell in the wireless communication system, wherein the second cell is associated with a second RAT;
- detect that a fifth generation core (5GC) is connected;
- determine that a timer is running in the UE on the second RAT;
- and
- in response to determine that the timer is running in the UE on the second RAT, perform an Inter Radio Access Technology (IRAT) Radio Resource Control (RRC) re-establishment procedure on the second cell when the RLF is occurred on the first cell associated with the first RAT.
