Abstract: There is provided mechanisms for adapting beamformed transmission from a base station. A method is performed by a control node. The control node is configured to control the beamformed transmission. The method comprises obtaining a first piece of information indicative of distance to, and direction towards, a radio communication site relative the base station. The method comprises obtaining a second piece of information indicative of operating radio frequency band of the radio communication site. The method comprises adapting the beamformed transmission so as to keep emission from the base station in the direction towards the radio communication site that contributes within the operating radio frequency band of the radio communication site within a prescribed limit.

Abstract: The embodiments herein relate to a method performed by a first node (101) for enabling testing of at least a part (105, 108) of the first node (101) in a deployed network. The first node (101) determines that at least a part (105, 108) of the first node (101) should be tested, and determines a direction in which to transmit or receive a test signal (200) to or from a second node (103). The first node (101) transmits the test signal (200) OTA in the determined direction to the second node (103) if a transmitter of the first node (101) should be tested. The first node (101) receives the test signal (200) OTA in the determined direction from the second node (103) if a receiver of the first node (101) should be tested.

Abstract: The embodiments herein relate to a method performed by a testing device for enabling testing of a communication node. The testing device measures a test parameter associated with RF characteristics of the communication node when it is located at a test location during a first condition. The communication node is configured with a node setting during the measurement in the first condition. The testing device measures the test parameter associated with the RF characteristics of the communication node when it is located at the test location during a second condition. The communication node is configured with the same node setting in the second condition as in the first condition. The testing device checks whether a result parameter associated with the test parameter measured during the first and second condition fulfills a requirement.

Abstract: A method performed by a network node for determining a beam to be transmitted to at least a first User Equipment, UE is provided. The network node determines (903) a beam to be transmitted to at least a first UE based on an obtained average spatial profile of radiated power in each direction. The average spatial profile of radiated power is based on an spatial profile of radiated power averaged over any one or more out of a frequency interval and a time interval.

Abstract: There is provided mechanisms for determining direction of a second radio transceiver device with respect to a first radio transceiver device. The first radio transceiver device is configured to communicate with beams in a beam set. A method is performed by a processing unit. The method comprises obtaining a vector of radio parameter measurements from measurements performed on a radio link between the first radio transceiver device and the second radio transceiver device for one and the same location of the second radio transceiver device. The vector comprises a radio parameter measurement per each beam in the beam set. The method comprises determining the direction of the second radio transceiver device with respect to the first radio transceiver device by comparing the vector of radio parameter measurements to a set of candidate direction profiles.

Abstract: A method and apparatus for performing TRP measurements of an antenna system uses a sampling grid that takes into account the spherical geometry and the directivity of the antenna under test, while considering test time. The optimization of the sampling grid balances the trade-off between reducing the number of samples to reduce test time, and ensuring accuracy of the TRP estimates.
