1. A method for wireless communication, comprising:

  • transmitting, from a first user equipment (UE) to a second UE, a pilot indicating that the first UE outside a coverage area of a base station desires to communicate with the base station that currently serves the second UE, the pilot being used for at least a pilot measurement between the first UE and the second UE, and the pilot being used to detect the first UE;

    determining, at the first UE, that the second UE will serve as a relay station between the base station and the first UE based at least in part on the pilot measurement, and the base station being unaware of the first UE prior to receiving the pilot measurement from the second UE; and

    transmitting data, from the first UE to the second UE, for subsequent transmission to the base station.
