  • Patent number: 10123281
    Abstract: According to some embodiments, a first network node manages a transmit power of a first wireless device capable of device-to-device, D2D, communication. The first network node receives at least one measurement report from at least one of the first wireless device and a second wireless device in D2D communication with the first wireless device. The measurement report indicates a received signal measurement or path loss with respect to the other of the first wireless device and the second wireless device and/or a received signal measurement or path loss with respect to a victim node. The first network node sends the first wireless device instructions to make an adjustment of the transmit power that the first wireless device uses in the D2D communication. The adjustment is at least partially based on the received measurement report.

  • Patent number: 9516551
    Abstract: The embodiments herein relate to a method in a first D2D UE (101) arranged for performing a D2D operation with at least one second D2D UE (101?). The first D2D UE (101) acquires one or more coverage specific parameters for use by the first D2D UE (101) for the D2D operation. The first D2D UE (101) determines the network coverage scenario in which the first D2D UE (101) is operating or is expected to operate. The first D2D UE (101) selects one or more coverage specific parameters belonging to the acquired one or more coverage specific parameters. The first D2D UE (101) uses the selected one or more coverage specific parameters for performing the D2D operation in the determined network coverage scenario.

  • Publication number: 20160337007
    Abstract: In particular embodiments, a method for determining a beam-forming weight for coordinated multipoint communication with a first network node is performed by a wireless device in a cluster set of wireless devices configured to operate as a virtual device. The method includes receiving from a first network node, via a first channel, a first network RS coded with a first network beamforming weight associated with the cluster set. A second network RS is received from a second network node via the first channel. A device beamforming weight is calculated based on the first network RS received from the first network node and the second network RS received from the second network node. The calculation may be performed during a first iteration and may be independent of any channel information from any other wireless device in the cluster set of the wireless devices operating as a virtual device.
