Abstract
The present specification provides a method for performing a radio link failure (RLF) recovery procedure in a wireless communication system. The method performed by a first user equipment (UE) includes, wherein the first UE is connected to a base station via a UE-to-UMTS (Uu) link and is connected to a second UE via a sidelink, determining a path for performing the RLF recovery procedure when a RLF is detected on the Uu link, and performing an RRC connection re-establishment procedure in order to recover the RLF through the determined path.
Claims12
A method for performing, by a first user equipment (UE), a radio link failure (RLF) recovery procedure in a wireless communication system, the method comprising:
- wherein the first UE is connected to a base station via a UE-to-UMTS (Uu) link and is connected to a second UE via a sidelink,
- determining a path for performing the RLF recovery procedure when a RLF is detected on the Uu link;
- and
- performing an RRC connection re-establishment procedure for recovering the RLF through the determined path,
- wherein the path for performing the RLF recovery procedure is determined based on a factor related to data characteristic of the first UE,
- wherein the determined path is the Uu link or the sidelink.
A method for reselecting, by a first node, a relaying path in a wireless communication system, the method comprising:
- wherein the first node is connected to a second node via a UE-to-UMTS (Uu) link,
- transmitting and receiving data with one or more nodes via the Uu link;
- reselecting the relaying path when a radio link failure (RLF) is detected on the Uu link or a specific condition is met;
- and
- transmitting and receiving data with at least one node through the reselected relaying path,
- wherein the specific condition is whether to support a 5G Qos indicator (5QI) level on a node, whether to support a specific service type on the node, a congestion level of a hop, or a beam state.
A first user equipment (UE) for performing a radio link failure (RLF) recovery procedure in a wireless communication system, the first UE comprising:
- a radio frequency (RF) module configured to transmit and receive a radio signal;
- and
- a processor functionally connected to the RF module,
- wherein the first UE is connected to a base station via a UE-to-UMTS (Uu) link and is connected to a second UE via a sidelink,
- wherein the processor is configured to:
- determine a path for performing the RLF recovery procedure when a RLF is detected on the Uu link;
- and
- perform an RRC connection re-establishment procedure in order to recover the RLF through the determined path,
- wherein the path for performing the RLF recovery procedure is determined based on a factor related to data characteristic of the first UE,
- wherein the determined path is the Uu link or the sidelink.
