Patent ID: 8467408

Claim:
A method for use in a base station, the method comprising: establishing in-phase and quadrature sub-channels in a same timeslot on a first downlink channel, wherein a first wireless transmit/receive unit (WTRU) is assigned to a first sub-channel of the in-phase and quadrature sub-channels and a second WTRU is assigned to a second sub-channel of the in-phase and quadrature sub-channels in the same timeslot; controlling transmit power for active transmissions to the first WTRU and the second WTRU in each sub-channel independently; transmitting information for the first WTRU on the first sub-channel and information for the second WTRU on the second sub-channel; monitoring channel conditions on the first downlink channel; and assigning the second WTRU from the second sub-channel to a second downlink channel based on the monitored channel conditions.
