Abstract:
A method of facilitating a remote station hand-off between single carrier base stations and multi-carrier base stations, comprising the steps of:determining that a remote station is receiving signals in a first frequency band in accordance with a single carrier protocol; determining that said remote station is transmitting signals in a second frequency band in accordance with said single carrier protocol, wherein said second frequency band is substantially the same width as said first frequency band; receiving signal strength measurements of various base stations in a first message from said remote station; determining that at least one of said various base stations is single carrier compliant and that at least one of said various base stations is multi-carrier compliant; and transmitting a second message to said remote station that indicates that said remote station should begin receiving signals in accordance with a multi-carrier protocol in a third frequency band that is larger than said first frequency band.
