摘要： Various methods for managing device-to-device interference are provided. One example method includes receiving an expected interference level for a resource block, where the expected interference level is represented by data indicative of interference associated with the resource block due to device-to-device communications using the resource block. The example method further includes selecting the resource block for a device-to-device communications session based at least in part on the expected interference level for the resource block. Similar and related example methods and example apparatuses are also provided.

摘要： In accordance with an example embodiment of the present invention, a method is disclosed that comprises collecting a set of neighbor cellular user equipment (UE) interferences from at least one neighbor cellular UE at a device-to-device (D2D) UE at least in part based on a decoded first uplink radio resource management (RRM) message and computing a first set of average neighbor UE interferences based on the set of collected neighbor cellular UE interferences. The method also comprises predicting at least one interference scenario at least in part based on the first set of average neighbor cellular UE interferences and a decoded second uplink RRM message. The method also comprises selecting a resource for data transmission to a pairing D2D UE at least in part based on the first set of average neighbor cellular UE interferences, and transmitting data over the selected resource to the pairing D2D UE.

摘要： Methods and apparatus, including computer program products, are provided for allocating resources among user elements. In one aspect there is provided a method. The method may include receiving, at a base station, information from a user element. The information may include at least one bit representing whether direct transmissions between pairs of user elements cause interference to the user element. The base station may schedule, based on the received information, the user element into at least one of a first subframe, when the received information indicates a risk of interference from the direct transmissions between the pairs of user elements, and into a second subframe, when the received information indicates no risk of interference from the direct transmissions between the pairs of user elements. Related apparatus, systems, methods, and articles are also described.
