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

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for utilizing multiple carriers in high speed packet access communications.SOLUTION: A WTRU capable of receiving on a single downlink carrier at a time may tune a receiver to one downlink carrier and switch the downlink carrier in accordance with a configured pattern. The WTRU may switch the downlink carrier from an anchor carrier to a non-anchor carrier at an HS-SCCH sub-frame boundary, and switch back at an end of a subsequent HS-PDSCH subframe. The WTRU may switch the downlink 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 from the supplementary carrier to another carrier on the basis of carrier switching order.
