Device-to-device communication scenario

摘要

A method, apparatus, and computer program for supporting simultaneous multi-use of resources of a backhaul link between a relay base station and another base station of a cellular radio network. The relay base station is configured to forward transmission resources of the backhaul link to at least one communication device located in a cell of the relay base station. The communication device(s) is/are then configured to utilize the resources of the backhaul link for device-to-device connections.

1. A method, comprising:
receiving, at a relay base station of a cellular radio network, parameters defining transmission resources for a backhaul link between the relay base station and another base station of the cellular radio network; transmitting, by the relay base station, at least some of the received parameters of the backhaul link to at least one communication device operating in a cell covered by the relay base station so as to enable simultaneous multi-utilization of-the transmission resources of the backhaul link; communicating, by the relay base station, relay data in the transmission resources defined by the received parameters; and transmitting, by the relay base station, interference control information to the at least one communication device, wherein the interference control information includes interference information for at least one device-to-device link that utilizes the transmission resources of the backhaul link, and wherein the interference information includes a threshold parameter that limits, when the at least one communication device is utilizing the transmission resources of the backhaul link for the at least one device-to-device link, transmission power of the at least one communication device.
