摘要： In radio transmission between a mobile communication network and a user equipment, signals are received in a subframe comprising a first group of one or more resource elements and a second group of one or more resource elements. The first group is subject to a first level of interference from at least one further radio channel while the second group is subject to a second level of interference from the at least one further radio channel. A first measurement and a second measurement are performed. Based on the first and second measurements the interference from the at least one further radio channel is estimated and interference mitigation is performed.

摘要： A first communication device is configured for device-to-device (D2D) communications with a second communication device. A method by the first communication device includes obtaining information on duplex configuration of a radio network node that may affect resource allocation by the first communication device for D2D communication with the second communication device. The method further includes deriving a set of resource patterns (RPTs) based on the information, selecting one RPT among the set of RPTs based on scheduler information, and signaling an index that is used to identify the selected RPT to the second communication device. Related methods by a communication device to derive resources to be used for D2D reception from another communication device based on a selected RPT are disclosed.
