    摘要: A method and arrangement for transmitting and receiving RF signals, associated with different radio interfaces of communication systems, employ a direct conversion based transceiver which substantially comprises one receive signal branch and one transmit signal branch. Mixing frequencies of the different systems are generated by a single common by use of an output frequency divider in combination with the synthesizer, and by use of filtering corresponding to a system channel bandwidth by means of a controllable low-pass filter operating at baseband frequency.

    摘要: A method for processing interference in wireless communication at a base station, wherein at least some of a plurality of (Radio Frequency) RF channels in the base station operates at a current operating frequency point assigned to the base station includes detecting interference of one or more candidate frequency points by using at least one RF channel, wherein the one or more candidate frequency points are different from the current operating frequency point; reporting result of detecting interference of the one or more candidate frequency points to a resource manager; and in response to the resource manager assigning one of the one or more candidate frequency points to the base station, notifying a user to switch from the current operating frequency point to the assigned candidate frequency point.

    摘要: Embodiments provide a transmitter and a method for transmitting data via a combination of a first signal modulated at a first carrier frequency, and a second signal modulated at a second carrier frequency, different to the first carrier frequency. In one embodiment the transmitter includes a local oscillator and is configured to adaptively configure the local oscillator to operate at a first local oscillator frequency and an alternative local oscillator frequency, different to the first frequency, in dependence on a required signal strength of the first signal relative to a required signal strength of the second signal.
