Power control in orthogonal sub-channels in wireless communications

摘要

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.

1. A method for use in a first wireless transmit/receive unit (WTRU), for detecting transmissions for one of a plurality of users on a same physical resource, the method comprising:
receiving, by the first WTRU, on a physical resource in a same time slot, a first data for the first WTRU via a first one of in-phase and quadrature phase sub-channels on the physical resource and a second data for a second WTRU via a second one of in-phase and quadrature phase sub-channels on the same physical resource, wherein a transmit power of the in-phase sub-channel and a transmit power of the quadrature phase sub-channel are independent of each other; processing, by the first WTRU, the first data; and not processing, by the first WTRU, the second data.
