Claim:
1. A method in a base station for determining channel interference in a radio network comprising a device-to-device (D2D) capable user equipment (UE) and the base station serving at least one cellular UE, said method comprising: configuring the at least one cellular UE with a Demodulation RS (DMRS) related parameter; transmitting the DMRS related parameter associated with the at least one cellular UE to the D2D capable UE; transmitting a DMRS related configuration parameter, including a Cyclic Shift (CS) to both the D2D capable UE and the at least one cellular UE; and obtaining information of interference to the D2D capable UE measured by the D2D capable UE using the DMRS related parameter.
