METHOD AND APPARATUS FOR CONTROLLING UPLINK MULTIPLE-INPUT MULTIPLE-OUTPUT (MIMO) TRANSMISSIONS

摘要

A method and apparatus for controlling uplink (UL) multiple-input multiple-output (MIMO) transmission parameters and transmissions are disclosed. A wireless transmit/receive unit (WTRU) may determine parameters, such as block sizes or transport format combinations, for transmission of a plurality of streams. The WTRU may adjust the transmission power to ensure that dedicated physical data channels are transmitted at the same level on both streams while using a WTRU calculated virtual grant on a secondary stream.
