Abstract: This document discloses a solution for inter-cell interference control in a cellular communication system. A method comprises: detecting, by an access node managing an interfered cell in a cellular communication system, inter-cell interference from an interfering cell; determining whether or not interference cancellation performed for a signal received through the access node is capable of cancelling said inter-cell interference; and controlling, on a basis of a result of said determining, uplink transmit power of a terminal device on time-frequency resources allocated to the terminal device.

Abstract: Methods and apparatus for controlling devices capable of device-to-device communication are disclosed. A network node determines at least two resource allocations for device-to-device communication between the devices. Information about the at least two resource allocations is then communicated to at least one of the devices for device-to-device communication. The device can then communicate with another device capable of device-to-device communication using one of the at least two resource allocations.

Abstract: The invention is in relation to a method initiating a device discovery process communications between user terminals capable of communicating on device-to-device and cellular communications links in the cellular communications network; determining a first parameter indicating interference of transmissions from a first user terminal on a device-to-device communications link to a second user terminal; determining a second parameter indicating interference of transmissions from the first user terminal on a cellular communications link; applying, on the basis of the first parameter exceeding the second parameter, asymmetric communications between the user terminals such that transmissions from the first user terminal to the second user terminal are communicated over the cellular communications links via infrastructure of the cellular communications network and transmissions from the second user terminal to the first user terminal are communicated over the device-to-device communications link.
