The main reason is to obtain higher throughput. Since the BCCH TRX carries most of the signaling channels in the cell, BCCH frequency planning is normally performed with a higher target C/I (in other words, more frequencies). As a result, data channels on the BCCH TRXs will normally have a higher C/I compared to those on non-BCCH TRXs, and by extension, higher data throughput.
