Techniques for sidelink based discovery

A discoveree user equipment (UE), comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the discoveree UE to:
• receive, from a network entity, a discovery message requesting information associated with establishing sidelink communication with a discoverer UE, the discovery message comprising one or more parameters that indicate a discovery model type, a geographic range relative to the discoverer UE, a cast type, or a combination thereof;
• and
• transmit, to the network entity, a response to the discovery message indicating whether the discoveree UE is available for discovery by the discoverer UE in accordance with the one or more parameters indicated in the discovery message.

A method for wireless communications, at a discoverer user equipment (UE), comprising:

• transmitting, to a network entity, a discovery message requesting information for discovery of discoveree UEs for sidelink communication, the discovery message comprising one or more parameters that indicate a discovery model type, a geographic range relative to the discoverer UE, a cast type, or a combination thereof;
• receiving, from the network entity, a response to the discovery message indicating a list of one or more of the discoveree UEs that satisfy criteria for the discovery for the sidelink communication according to the one or more parameters;
• and
• performing, with at least one UE from the list of one or more of the discoveree UEs, a wireless connection setup procedure in accordance with the one or more parameters.
