  • Transmitting node and method therein for performing data transmissions to at least one receiving node on a radio channel in a wireless communications network
    Patent number: 10075978
    Abstract: A transmitting node and a method performed by a transmitting node for performing data transmissions to at least one receiving node on a radio channel in a wireless communications network. First, the transmitting node sets at least two contention window sizes. The at least two contention window sizes are separately determined based on information associated with the least one receiving node. Then, the transmitting node defers a first transmission of data to the at least one receiving node for a first period and also defers at least one second transmission of data to the at least one receiving node. Further, the transmitting node performs a first or at least one second transmission of data to the at least one receiving node when an outcome of a corresponding first and at least second periods of observation of the radio channel, respectively, is that the radio channel is idle.

  • FIRST COMMUNICATION DEVICE AND METHODS PERFORMED THEREBY FOR MANAGING BEAMFORMING BY A SECOND COMMUNICATION DEVICE FOR TRANSMISSION OF A SIGNAL
    Publication number: 20180138958
    Abstract: A method performed by a first communication device for managing beamforming by a second communication device for transmission of a signal. The first and second communication devices operate in a wireless communications network having a zone in which a radio frequency electromagnetic field strength is required by a regulation to be below a threshold. The first communication device adjusts at least one of an output power and a beam shape in the beamforming. The adjusting is such that the radio frequency electromagnetic field strength in the zone for the output power and the beam shape in the beamforming is below the threshold. The first communication device initiates transmission of the signal to a third communication device operating in the wireless communications network using beamforming with the adjusted at least one of the output power and the beam shape.
