Abstract

A communication device is described including a receiver, a determiner configured to determine, for a first data transmission via a first communication channel and a second data transmission via a second data communication channel, wherein the first data transmission and the second data transmission overlap in time, a first time period during which the receiver is to receive data transmitted in the first data transmission and a second time period during which the receiver is to receive data transmitted in the second data transmission based on information about the quality of data transmission via the first communication channel and based on information about the quality of data transmission via the second communication channel and a controller configured to control the receiver to receive data transmitted in the first data transmission during the first time period and to receive data transmitted in the second data transmission during the second time period.
