Inter-frequency handover for multiple antenna wireless transmit/receive units

摘要

A method and an apparatus for a Wireless Transmit/receive Unit (WTRU) to perform inter-frequency measurements and inter-frequency soft handover from an originating Base Station (BS) operating at a first frequency to a destination BS operating at a second frequency. The WTRU has at least two antennas, where each antenna initially receiving at the first frequency. The method of the invention performs inter-frequency measurements of the channel on the second frequency using at least one of the antennas that were used for performing data reception on the first frequency. The invention includes a method and an apparatus for performing inter-frequency handover. The inter-frequency handover includes soft handover and hard handover.
