Handling of simultaneous network communication transmission and D2D communication reception or simultaneous network communication reception and D2D communication transmission

A method for use in a first radio frequency communication device comprising a radio frequency communications interface and a controller, said method comprising:

• establishing a network communication link with a network node and said first radio frequency communication device, and to
• establish a device-to-device communication link with a second radio frequency communication device and said first radio frequency communication device via said radio frequency communication interface;
• determining a simultaneous communication in a subframe interval is to be performed comprising either a network transmission over said network communication link with said network node and said first radio frequency communication device and a D2D reception over said device-to-device communication link with said second radio frequency communication device and said first radio frequency communication device, or a network reception over said network communication link with said network node and said first radio frequency communication device and a D2D transmission over said device-to-device communication link with said second radio frequency communication device and said first radio frequency communication device;
• determining there is a transmission problem related to said simultaneous communication in said subframe interval;
• determining a mitigation technique for reducing adjacent channel interference;
• and
• performing said simultaneous communication of said network transmission and said D2D reception or said simultaneous communication of said network reception and said D2D transmission according to said mitigation technique to mitigate said transmission problem.

A network node comprising a radio frequency communications interface and a controller, said network node being configured to serve at least one first radio frequency communication device being configured for both a network communication link and for a device-to-device communication link with a second radio frequency communication device, wherein said controller is configured to:

• determine a mitigation technique for reducing adjacent channel interference to mitigate a problem related to transmission or reception of signals experienced by, or expected to be experienced by, the first radio frequency communication device for either simultaneous network transmission over said network communication link with said network node and said first radio frequency communication device and a D2D reception over said device-to-device communication link with said second radio frequency communication device and said first radio frequency communication device in a subframe interval, or for simultaneous network reception over said network communication link with said network node and said first radio frequency communication device and a D2D transmission over said device-to-device communication link with said second radio frequency communication device and said first radio frequency communication device in a subframe interval;
• and
• transmit said mitigation technique to said first radio frequency communication device to allow simultaneous communications in said subframe interval.
