Patent ID: 8588803

Claim:
A method, comprising obtaining at a network node a scheduling reference point with a fluctuation range based at least in part on at least one metric for a plurality of cellular user equipments and at least one pair of device-to-device user equipments, the scheduling reference point being at least one of a bit error rate, a data-block error rate, a packet loss rate, a delay, a throughput, and a transmission power, and the fluctuation range centers on the scheduling reference point and includes an upper bound and a lower bound; signaling the scheduling reference point and the fluctuation range to the at least one pair of device-to-device user equipments; allocating radio resources to the at least one pair of device-to-device user equipments according to one or more allocation criteria; receiving metrics updates from the at least one pair of device-to-device user equipments and the plurality of cellular user equipments; receiving a request for a change of radio resources from the at least one pair of device-to-deice user equipments that is determined based on the metrics updates; and adjusting the scheduling reference point and the fluctuation range according to the received metric updates.
