摘要： A method of controlling a set of devices (101, 102, 103, 104 and 105) is proposed. The method is performed by a voice-controll ed device (100). In response to receiving (S201) a first voice command of a user comprising a first reference to at least one device of the set of devices and a control command to be performed on the at least one device of the set of devices, the voice-controlled device presents (S202) an identifier in association with each of the at least one device of the set of devices. In response to receiving (S203) a second voice command from the user comprising a second reference to one or more of the identifiers, the voice-controlled device controls (S204) one or more of the at least one device of the set of devices which can be identified based on the second reference comprised in the second voice command to execute the control command comprised in the first voice command.

摘要： A method for beam assignment support comprises obtaining of, in a radio base station, a set of channel gain estimations representing potential transmissions in a set of beams to a user equipment. A set of bias values is obtained, representing connection quality predictions for a respective beam of the set of beams for transmission to the user equipment. The connection quality predictions are estimations calculated from measures of previous traffic load, previous radio quality of transmissions, and/or previous beam assignments of the first transmission reception point. A set of biased channel gain estimations is determined by weighting the channel gain estimations in dependence of respective bias values. A beam assignment based on the biased channel gain estimations is initiated. A method also for determining bias values in a network node as well as radio base stations.

摘要： A method and a radio network node (110) for managing precoder reports from a set of user equipments (120) are disclosed. Each of the precoder reports indicates a precoder selected, by a respective user equipment (121, 122, 123) of the set of user equipments (120), to be used by the radio network node (110) for transmission to the respective user equipment (121, 122, 123). The radio network node (110) receives (202), in a first time interval, a first set of precoder reports from the set of user equipments (120). The radio network node (110) receives (204), in a second time interval, a second set of precoder reports from the set of user equipments (120). The radio network node (110) determines (209) a first distribution of precoders for the set of user equipments and a second distribution of precoders for the set of user equipments, wherein the precoders in the first distribution are indicated by the first set of precoder reports and the precoders in the second distribution are indicated by the second set of precoder reports, whereby a change in distribution of precoders for the set of user equipments (120) is detected. A corresponding computer program and a carrier therefor are also disclosed.

摘要： A method performed by a network node for reducing Inter-Symbol Interference, ISI, in a wireless communications network. The network node provides a number of beams for transmissions between the network node and respective one or more first User Equipments, UEs, and a second UE. During a time period, network node obtains (301) measures of ISI per beam out of the number of beams related to transmissions between the network node and the one or more first UEs. The network node then reduces (302) the ISI in the wireless communications network 100 by obtaining a beam for transmission between the network node and the second UE. The beam is selected out of the number of beams by taking the obtained measures of ISI per beam into account.

摘要： A method performed by a first communication device operating in a wireless communications network is described herein. The first communication device receives, via an interface of the first communication device, a first indication from a user of the first communication device. The first indication explicitly indicates a desired location to receive a wireless service. The first communication device provides, based on the received first indication, a second indication to a second communication device operating in the wireless communications network. The second indication indicates that a space corresponding to the indicated desired location, is a desired space to receive the wireless service from the wireless communications network. The first communication device also initiates obtaining the wireless service from the second communication device whenever the first communication device is located in the space.

摘要： There is presented a method for a network node, or for a user equipment, for adapting a beam sweep in a communications network. The communications network includes the network node, a transmission point, TP, and a user equipment, UE. The method includes determining at least one parameter related to the angular speed of the UE relative to the transmission point. The method further includes adapting at least one parameter associated with the beam sweep based on the parameter related to the angular speed.

摘要： A method performed by a radio node for increasing a throughput of a MIMO channel. The radio node operates in a wireless communication network 100. The beams are beamformed at a transmitter of the radio node. The beams comprise: A first beam In comprising a first beam gain in a first direction, and at least one second beam wherein each at least one second beam comprises a respective second beam gain in a respective second direction. When decided that the signal strength on the first beam is a first threshold stronger than the signal strength on each respective at least one second beam, and the signal strength on the at least one second beam is above a second threshold, the radio node increasing the throughput of the MIMO channel by suppressing (302) the first beam with respect to its beam gain.

摘要： A network node and a method performed thereby for communicating with a wireless device are provided. The network node is operable in a first communication network, and provides a PCell in a licensed frequency band and a SCell in an unlicensed frequency band. The method comprises determining that a channel quality for the SCell does not meet a predetermined threshold; and when the channel quality for the SCell not meeting the predetermined threshold is due to interference from devices and/or nodes not belonging to the first communication network, triggering a channel switch of the SCell.
