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: When a radio bearer for sending packets to a UE is split between master and secondary network nodes, then based on relative network conditions (such as relative link quality in view of latency targets or other conditions that reflect user-plane loading) between that master and secondary network nodes a redundancy retransmission mode may be selected from among multiple redundancy retransmission modes. Each of these redundancy retransmission modes define a different protocol for retransmitting multiple copies of selected ones of the packets to the UE over the split radio bearer. These multiple copies are then wirelessly retransmitted to the UE over the split radio bearer according to the selected redundancy retransmission mode. In one example there are 4 possible modes and different modes retransmit PDCP PDUs versus RLC PDUs; in one mode the master and secondary network nodes both perform retransmissions of the identical selected packets.

Abstract: An example technique includes receiving, by a user device, a first signal including a first user device-specific signal from a base station and one or more interfering signals, the first user device-specific signal being received based on a first modulation and coding scheme (MCS), determining, by the user device, whether the user device can perform interference cancellation for the one or more interfering signals, sending, by the user device to the base station, an interference cancellation feedback message including at least, for each of the one or more interfering signals, an interference cancellation capability indication that indicates whether or not the user device can perform interference cancellation for the interfering signal, receiving an updated MCS, wherein the updated MCS is based, at least in part, on the interference from the interference cancellation feedback message, and receiving, by the user device based on the updated MCS, a second signal.
