Abstract
A method and apparatus for power control for wireless transmissions are disclosed. A wireless transmit/receive unit (WTRU) may determine a first transmit power for a first physical channel for a first serving cell in a first timing advanced group (TAG) and a second transmit power for a second physical channel for a second serving cell in a second TAG. The first TAG may be associated with a first timing advance value and the second TAG may be associated with a second timing advance value. The WTRU may determine a WTRU configured maximum output power (PC MAX) for an overlapping portion, which may be a portion of a transmission of the first channel in a first slot that overlaps in time with a portion of a transmission of the second channel in a next slot. The WTRU may adjust at least one of the first physical channel and the second physical channel.
