Abstract

In embodiments, apparatuses, methods, and storage media may be described for establishing a direct connection between two UEs. Each UE may be provisioned with a temporary identifier by a server of a wireless network of the UE. The UEs may then be configured to broadcast the temporary IDs in radio signals over radio resources that are separate from the radio resources of the network. The temporary IDs may not contain identifying information of the broadcasting UE that is interpretable without receiving further information from the network.

1. An apparatus to be employed in a user equipment (UE), the apparatus comprising:

transmit circuitry to transmit, to a server of a wireless network, a proximity request message to enable discovery of a remote UE; and

receive circuitry to;
