1. A device comprising circuitry including a wireless transmitter, a wireless receiver, and a processor, the circuitry being configured to:
transmit spread spectrum signals in a band and to receive responses thereto in the band from a wireless transmit/receive unit (WTRU), the responses including signals reflected from the WTRU;
determine a first signal-to-noise ratio (SNR) of a first response from the WTRU;
on a condition that the first SNR is below a threshold, transmit spread spectrum signals in a first sub-band and a second sub-band of the band;
determine a second SNR of a second response from the WTRU in the first sub-band or the second sub-band; and
on a condition that the second SNR is above the threshold:
determine a parameter associated with the WTRU based on the second response,
determine a first channel in the first sub-band or a second channel in the second sub-band based on the parameter, and
cause a link to be established with the WTRU using at least one of the first channel or the second channel.
