Claim:
1. A method of managing power headroom reports associated with a wireless transmit/receive unit (WTRU), the method comprising: determining, for a transmission time interval (TTI), whether the WTRU includes at least one real uplink transmission on a serving cell and whether a Power Management Power Reduction (P-MPR) for the serving cell has changed by more than a threshold after a last power headroom report was transmitted by the WTRU when the WTRU included at least one other real uplink transmission on the serving cell; and on condition that the WTRU, for the TTI, includes the at least one real uplink transmission on the serving cell and that the P-MPR for the serving cell has changed by more than the threshold after the last power headroom report was transmitted by the WTRU when the WTRU included the at least one other real uplink transmission on the serving cell, triggering a new power headroom report.
