METHOD AND APPARATUS FOR UTILIZING MULTIPLE CARRIERS IN HIGH SPEED PACKET ACCESS COMMUNICATIONS TECHNICAL FIELD

摘要

A method and an apparatus for utilizing multiple carriers are disclosed. A wireless transmit/receive unit (WTRU) capable of receiving on a single downlink carrier at a time may tune the receiver to one downlink carrier and switch the downlink carrier in accordance with a configured pattern. The WTRU may switch the carrier from an anchor carrier to a non-anchor carrier at a high speed shared control channel (HS-SCCH) sub-frame boundary, and switches back at an end of a subsequent high speed physical downlink shared channel (HS-PDSCH) subframe. The WTRU may switch the carrier at an HS-PDSCH sub-frame boundary. A WTRU capable of receiving on multiple downlink carriers simultaneously may tune the receiver to an anchor carrier and a supplementary carrier, and switch the supplementary carrier to another carrier based on a carrier switching order. The carrier switching order may be received via an HS-SCCH or via layer 2 signaling.

1. A method, implemented in a network element, for utilizing multiple carriers, the method comprising:
sending an indication to a wireless transmit/receive unit (WTRU) via a control channel on a first downlink carrier, wherein the indication indicates that the WTRU is to receive data on a second downlink carrier, and wherein the first downlink carrier and the second downlink carrier are characterized by different subframe configurations for CQI reporting; and sending the data on the second downlink carrier in accordance with the indication.
