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.

摘要： A method, apparatus, computer readable medium is provided to perform resource coordination among multiple cells to cancel near-far interference for device-to-device transmission, including cross-cell device-to-device transmission. In this context, a dedicated resource exchanging channel can be defined between cellular user equipment and device-to-device user equipment for interference control and resource coordination. A cellular user equipment can forward its uplink resource grant information over the dedicated resource exchanging channel when it determines potential interference. A device-to-device user equipment can monitor the dedicated resource exchanging channel in order to identify one or more resources that can potentially interfere with device-to-device transmission.

摘要： The present invention discloses a method, an apparatus and a computer program for resource contention in device-to-device communication links. The method partitions the time-frequency radio resource grid with a resource block set forming the resource unit in the grid, for all available, used and unusable frequency bands around a given virtual central frequency. Each resource block set is partitioned into a common control channel and a data channel. With a given procedure of control data transmission between transmitting and receiving user terminals, the resources are competed and shared. Frequency shifting with short distance frequency change or frequency transference with a larger frequency hopping into a free radio resource is available. The competition procedure is done in order to fairly share the frequency bands as a function of time between different device-to-device communication links in a localized manner.
