Relaying in a device-to-device communication system

A method of wireless communication at a remote user equipment (UE), comprising:

• receiving, on a downlink channel from a network entity, an indication to establish a connection with a relay UE on a sidelink channel, the relay UE being in a connected state with the network entity;
• establishing the connection with the relay UE on the sidelink channel;
• and
• receiving, from the relay UE on the sidelink channel, a sidelink grant associated with a radio network temporary identifier (RNTI) of the remote UE.

A relay user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• a processor in communication with the memory, wherein the processor is configured to:
• receive, on a downlink channel from a network entity, at least one message including a radio network temporary identifier (RNTI) of a remote UE associated with the relay UE;
• and
• transmit, on a sidelink channel, a sidelink grant associated with the RNTI to the remote UE.

A remote user equipment (UE) for wireless communication, comprising:

A remote user equipment (UE) wireless communication, comprising:

• means for receiving, on a downlink channel from a network entity, an indication to establish a connection with a relay UE on a sidelink channel, the relay UE being in a connected state with the network entity;
• means for establishing the connection with the relay UE on the sidelink channel;
• and
• means for receiving, from the relay UE on the sidelink channel, a sidelink grant associated with a radio network temporary identifier (RNTI) of the remote UE.

A computer-readable medium storing computer executable code for wireless communications at a remote user equipment (UE), comprising code for:

• receiving, on a downlink channel from a network entity, an indication to establish a connection with a relay UE on a sidelink channel, the relay UE being in a connected state with the network entity;
• establishing the connection with the relay UE on the sidelink channel;
• and
• receiving, from the relay UE on the sidelink channel, a sidelink grant associated with a radio network temporary identifier (RNTI) of the remote UE.
