Abstract
A method and apparatus for power control in a wireless communication involves establishing at least two orthogonal sub-channels within a channel for communication and controlling transmitted power in each sub-channel independently.
Claims16
A method for multiplexing transmissions for a plurality of users on a same physical resource, the method comprising:
- processing data to be transmitted to a first wireless transmit/receive unit (WTRU) and a second WTRU;
- and
- transmitting the data to the first WTRU and the second WTRU using a same physical resource in a same time slot, wherein the first WTRU is assigned to a first one of in-phase and quadrature sub-channels and the second WTRU is assigned to a second one of the in-phase and quadrature sub-channels on the same physical resource, and a transmit power on the in-phase and quadrature sub-channels is controlled independently.
An apparatus for multiplexing transmissions for a plurality of users on a same physical resource, comprising:
- a processor configured to process data to be transmitted to a first wireless transmit/receive unit (WTRU) and a second WTRU, and transmit the data to the first WTRU and the second WTRU using a same physical resource in a same time slot, wherein the first WTRU is assigned to a first one of in-phase and quadrature sub-channels and the second WTRU is assigned to a second one of the in-phase and quadrature sub-channels on the same physical resource, and the processor is further configured to control a transmit power on the in-phase and quadrature sub-channels independently.
