1. A method for use by a wireless transmit/receive unit (WTRU), the method comprising:
receiving sounding reference signal (SRS) configuration information, wherein the SRS configuration information indicates a plurality of SRS configurations;
determining a power headroom value associated with a first SRS transmission, wherein the power headroom value indicates whether the first SRS transmission would exceed a maximum power before a power adjustment is performed;
transmitting the power headroom value to a network in a medium access control (MAC) control element (CE);
receiving power control information from the network regarding a second SRS transmission subsequent to transmitting the power headroom value;
adjusting power for transmitting the second SRS transmission based on the received power control information; and
transmitting the second SRS transmission using the adjusted power.
