In a European first, BT and Ericsson have successfully demonstrated the transmission of 5G services in a wideband FDD (frequency division duplex) radio carrier (over 20MHz) within a sub-3 GHz spectrum band.
The breakthrough trial demonstrated the benefits of configuring a wide carrier bandwidth of 50MHz (50MHz downlink + 50MHz uplink) in EE’s 2.6GHz band and performing downlink aggregation with two TDD (time division duplex) carriers in EE’s 3.5GHz band. The trial also evaluated an intermediate carrier bandwidth of 30MHz.
