Abstract

Controlling 202 a transmitter to map com­mon and dedicated control channels, e.g. for cellular (LTE-based) transmissions, on two frequency blocks and controlling 204 the transmitter to transmit the frequency blocks utilising pair-wise frequency hopping on a shared spec­trum, e.g. license-exempt or unlicensed frequency bands. The transmitter may be further controlled to transmit on shared data channels using Listen-Before-Talk or channel contention between the devices communicating on the shared spectrum. Synchronisation signals may be mapped to the two frequency blocks. The transmitter may be further controlled to utilize frequency bands located between identified Wireless Local Area Network (WLAN) channels in the transmission of the two frequency blocks.
