Abstract:
The present invention provides a method in a base station for determining channel interference in a radio network comprising a device-to-device, D2D, capable UE and the base station serving at least one cellular UE, said method comprising: configuring the at least one cellular UE with a cellular uplink Reference Symbol, RS, related parameter; transmitting the cellular uplink RS related parameter associated with the at least one cellular UE to the D2D capable UE; and obtaining information of interference to the D2D capable UE measured by the D2D capable UE using the cellular uplink RS related parameter. The present invention also provides a corresponding method in D2D capable UE and the devices thereof. This achieves a more accurate the interference channel measurement in multi-cell and multi-antenna scenario.
