A system and method for mobility tracking of user equipment in a network includes a user equipment. The user equipment includes an antenna for receiving and sending signals to a plurality of network nodes in a network and a processor coupled to the antenna. The processor is configured to broadcast, using the antenna, a pilot signal to advertise the user equipment, receive, using the antenna, a pilot response from a first network node acting as a serving node for the user equipment, and communicate with the network through the serving node. The pilot signal includes a reference sequence for the network nodes to track followed by a payload including information about an identity of the user equipment. In some embodiments, the reference sequence varies based on a state of the user equipment. In some embodiments, the reference sequence is randomly selected.
