Abstract

A system and method provide single frequency, dual cell high-speed downlink packet access to a UMTS telecommunications system. A first downlink channel is provided from a first sector, and a second downlink channel is provided from a second sector, wherein the first downlink channel and the second downlink channel are in substantially the same carrier frequency. Feedback information such as a CQI and/or a PCI is provided on an uplink channel to facilitate adaptation of the respective downlink channels. Here, the uplink carrier may be in the same or a different carrier frequency than that of the downlink channels.
