Abstract: A data transmission system may comprise a first transmission chain comprising a first transmission power controller, the first transmission power controller being configured to operate in an open loop power control mode or in a closed loop power control mode; a second transmission chain; and a power control mode selector configured to select the first transmission power controller to operate in the open loop power control mode or in the closed loop power control mode based on at least one quantity indicative of interference induced by the second transmission chain in the first transmission power controller when operating in the closed loop power control mode.

Abstract: An apparatus for wireless communication is provided. The apparatus includes a processing circuit configured to receive data to be wirelessly transmitted within a predefined frequency range. Further, the processing circuit is configured to generate a first radio frequency transmit signal of a first frequency range based on the data, and to generate a second radio frequency transmit signal of a second frequency range based on the data. The first frequency range and the second frequency range are subranges of the predefined frequency range. The apparatus further includes a front-end circuit configured to supply the first radio frequency transmit signal to a first antenna, and to supply the second radio frequency transmit signal to a second antenna.
