    Abstract: A method in a network node for assisting a first user equipment in interference mitigation. The network node is comprised in a cellular communications network. The cellular communications network further comprises the first user equipment and a second user equipment. The second user equipment causes interference to the first user equipment when at least one of the first user equipment and second user equipment communicate by using Device-to-Device communication. The network node obtains information about the receiver of the first user equipment. The network node then determines one or more parameters required by the first user equipment for mitigating the interference. The parameters relate to the obtained information and to the interfering second user equipment. The network node then sends the one or more parameters to the first user equipment thereby assisting the first user equipment to mitigate interference caused by the second user equipment.

  • Method and apparatus for cooperative positioning in a wireless communication network
    Patent number: 9756493
    Abstract: According to the teachings herein, a wireless device that is a candidate for operating in the cooperative positioning advantageously activates that mode in response to detecting a warning situation. In some embodiments, the detection and/or activation operations are autonomously undertaken by the wireless device. In other embodiments, the wireless communication network provides warning situation detection and/or control of the cooperative positioning mode. More generally, the wireless communication network maintains a database identifying those wireless devices within a given service area that are cooperative positioning mode candidates—e.g., the devices having D2D communication capability and operational configurations that allow such operation. By the network providing such information in advance of a warning situation, the candidate devices have the information needed to efficiently discover or otherwise identify other such candidates.

  • Methods, Wireless Device, Base Station and Candidate Relay Station for Supporting D2D Communication Over Relay
    Publication number: 20170251507
    Abstract: A methods, base station, wireless device and candidate relay device for supporting a D2D communication between a first wireless device and a second wireless device over a relay. The base station receives (302) from the first device an identity of a candidate relay wireless device and a first quality metric (Geq) pertaining to a first relay link between the first device and the candidate relay device and to a second relay link between the second device and the candidate relay device. The base station also obtains (304) a second quality metric (G12) pertaining to a D2D link between the first and second devices, and a third quality metric (G1 BS) pertaining to a cellular link between the base station and the first device. When the first quality metric (Geq) indicates a better link quality than both the second metric (G12) and the third metric (G1 BS), the base station selects (310) a relay mode for the D2D communication with the candidate relay device as the relay and instructs the involved devices accordingly.

  • Method and arrangement for D2D discovery
    Patent number: 9736817
    Abstract: A method for sending beacon signals is provided. The beacon signals are to be received by a slave device to discover the master device for Device to Device communication. The master device receives information from a network node. The information informs about a set of available peer discovery resources to be used in a peer discovery frame by the master device for sending beacon signals. The beacon signals are detected by the slave device. The master device obtains a beacon transmission probability. At each specific peer discovery frame, the master device determines according to the beacon transmission probability, whether or not a beacon signal shall be transmitted during that specific peer discovery frame. When determining to transmit a beacon signal during that specific peer discovery frame, master device sends the beacon signal by choosing one of the peer discovery resources out of the received set of available peer discovery resources.

  • Methods and Apparatus to Account for Effective Downlink-Channels Arising from Beamforming Uplink Reference Signals
    Publication number: 20170187430
    Abstract: According to the teachings herein, a wireless device enhances uplink channel estimation at a node in a supporting wireless communication network by beamforming its uplink reference signal transmission towards the node, and correspondingly compensates for the effect of that beamforming when receiving a downlink transmission that was adapted in dependence on the uplink channel transmission. Such processing provides significant advantages in Multiple-Input-Multiple-Output, MIMO, systems that use a potentially large number of antennas for downlink MIMO transmissions and assume reciprocity between the uplink and downlink channels. In particular, uplink beamforming increases the received signal quality of the uplink reference signal used for estimating the uplink channel, while “automatic” compensation by the wireless device of the corresponding downlink transmission obviates the need for the network to know which precoder was used for uplink beamforming, or even that uplink beamforming is in use.
