Abstract
A network entity can trigger a remote user equipment (UE) to switch between an indirect communication link with a network to another indirect communication link or direct communication link with the network. In some aspects, the network entity can trigger the remote UE to perform an inter-gNB switching or sidelink switching using a radio resource control (RRC) connection release procedure or an RRC reconfiguration procedure.
Claims30
A method of wireless communication at a user equipment (UE), comprising:
- receiving redirection information in a radio resource control (RRC) message using a first connection with a wireless network via a first relay UE, wherein the redirection information comprises a priority order for selecting a relay UE;
- releasing, in response to the RRC message, the first connection with the wireless network;
- and
- establishing a second connection with the wireless network according to the redirection information.
A method of wireless communication at a wireless network, comprising:
- communicating with a remote user equipment (UE) using a first wireless connection via a relay UE;
- transmitting, to the remote UE, redirection information in a radio resource control (RRC) message to trigger the remote UE to disconnect the first wireless connection and establish a second wireless connection with the wireless network, wherein the redirection information comprises a priority order for selecting a relay UE;
- and
- communicating with the remote UE using the second wireless connection according to the redirection information.
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors connected with the memory,
- the one or more processors being configured to:
- receive redirection information in a radio resource control (RRC) message using a first connection with a wireless network via a first relay UE, wherein the redirection information comprises a priority order for selecting a relay UE;
- release, in response to the RRC message, the first connection with the wireless network;
- and
- establish a second connection with the wireless network according to the redirection information.
A network entity of a wireless network, comprising:
- a memory;
- and
- one or more processors connected with the memory, the one or more processors being configured to:
- communicate with a remote user equipment (UE) using a first wireless connection via a relay UE;
- transmit, to the remote UE, redirection information in a radio resource control (RRC) message to trigger the remote UE to disconnect the first wireless connection and establish a second wireless connection with the wireless network, wherein the redirection information comprises a priority order for selecting a relay UE;
- and
- communicate with the remote UE using the second wireless connection according to the redirection information.
