Sidelink capability signaling and configuration

An apparatus for wireless communication, comprising:

• a transceiver;
• a memory configured to store instructions;
• and
• one or more processors communicatively coupled with the transceiver and the memory, wherein the one or more processors are configured to execute the instructions to:
• transmit a capability indication message to a network entity, the capability indication message comprising a sidelink capability for direct communication between a user equipment (UE) and one or more secondary UEs;
• receive, at the UE, a configuration message from the network entity in response to the capability indication message, wherein the configuration message includes one or more configuration parameters based on the sidelink capability;
• and
• establish a communication link based on the one or more configuration parameters.

A method of wireless communication, comprising:

• receiving, by a network entity, a capability indication message from a user equipment (UE), the capability indication message comprising a sidelink capability for direct communication between the UE and one or more secondary UEs;
• transmitting, by the network entity, a configuration message to the UE in response to the capability indication message, wherein the configuration message includes one or more configuration parameters based on the sidelink capability;
• and
• establishing a communication link based on the one or more configuration parameters.
