1. A wireless transmit/receive unit (WTRU), comprising:
- a receiver and a processor configured to receive information from a network node indicating an assignment of periodic time intervals to transmit sounding signals; and
a transmitter and the processor configured to transmit sounding signals to the network node in the assigned periodic time intervals in response to the received information, wherein the WTRU does not transmit any data at a same time that the WTRU transmits the sounding signals, wherein the transmitted sounding signals from the WTRU are distinguishable from sounding signals from other WTRUs.

Abstract
A wireless transmit/receive unit (WTRU) includes circuitry configured to receive information from a base station indicating an assignment of periodic time slots to transmit sounding signals and circuitry configured to transmit sounding signals to the base station in the assigned periodic time slots in response to the received information, wherein a timing of transmission of the sounding signals in response to the received information differs between a time division duplex mode and a frequency division duplex mode, and wherein the transmitted sounding signals are distinguishable from sounding signals from other WTRUs.
