摘要： 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.

摘要： Methods and apparatus in a fifth-generation wireless communications network, including an example method, in a wireless device, that includes determining a reporting quality threshold for a parameter related to channel state information (CSI); performing a measurement for each of a plurality of beams from a first predetermined set of beams for evaluation; evaluating the measurement for each of the plurality of beams against the reporting quality threshold; discontinuing the performing and evaluating of measurements in response to determining that the reporting quality threshold is met for one of the beams, such that one or more beams in the first predetermined set of beams are not measured and evaluated; and reporting, to the wireless communications network, CSI for the one of the beams.

摘要： A MIMO communications system for communicating with a UE located inside a physical structure. The communication system includes a node comprising two node antennas. The node is configured for LOS wireless communication with at least first and second repeaters. The first and second repeaters each have a) an antenna provided outside the physical structure for outdoor MIMO communication with the node and b) a leaky cable provided inside the physical structure for indoor MIMO communication with the UE.
