When smart antennas are deployed in Frequency Division Duplex (FDD) applications, it is of great interest to know the correlation between the spatial uplink and downlink radio channels. This document describes the FDD radio channel measurement campaign conducted in the UMTS frequency band in an urban area in the city of Bristol. In the campaign, a wideband vector channel sounder was used to estimate the channels (almost) simultaneously. The channels had a bandwidth of 20 MHz and were centred as in the UTRA FDD bands. The transmitter was equipped with an omni-directional antenna and the receiver with an 8 element wideband dual polarised array. In future work, analysis of these measurement data will increase our knowledge of the correlation between the uplink and downlink channel in UMTS systems, guide us in the creation of a spatio-temporal FDD channel models, and give us a better understanding of the possibilities of robust downlink beamforming algorithms for FDD wireless networks
