Abstract: In one embodiment, an authentication scheme (500) that combines chaotic antenna array geometries with pseudorandom pilot sequences and antenna array activation sequences is provided. A receiving device (110A) receives a pilot signal (130) from a transmitting device (110B) (501). The receiving device computes a unique signature (125) for the transmitting device that captures differences between the received signal and expected pilot signal (503). The differences may be due to a unique antenna array geometry of the transmitting device, a pseudorandom pilot sequence used by the transmitting device, and an antenna array activation sequence used by the transmitting device. Later, this computed unique signature may be used by other receiving devices to authenticate the transmitting device (505; 507).

Abstract: A wireless transmit/receive unit (WTRU) may combine an alignment component with an FDM based symbol to produce a signal such that it is aligned to a duration of a CP of the FDM based symbol at a receiver upon reception. A component may be added to one or more subcarriers of the alignment signal to reduce peak-to-average ratio (PAPR) of the signal.
