Abstract: A method and apparatus determine a transmission beam for downlink transmissions, and provides first beamforming instructions for forming the transmission beam to a transmission path. The method and apparatus also determine at least one receiving beam that is a first receiving beam, and at least one receiving beam that is a second receiving beam. A first antenna sub-array is configured to provide a first plurality of concurrent receiving beams and a second antenna sub-array is configured to provide a second plurality of concurrent receiving beams, providing second beamforming instructions, for forming at least the first receiving beam and at least the second receiving beams, to a first receiving path and a second receiving path, respectively.

Abstract: Disclosed is a method comprising transmitting a first signal, obtaining an indication of a harmonic, wherein the harmonic is caused by the transmission of the first signal, determining, based on the indication of the harmonic, an estimation of the harmonic, receiving a second signal, wherein the second signal comprises the harmonic, and subtracting the estimation of the harmonic from the second signal.

Abstract: A method comprises selecting a beam to be scheduled for a slot that is upcoming, and selecting a terminal device to be scheduled in the selected beam. Selection of the terminal device is based on the terminal device considering the selected beam as its best beam. Physical resource blocks are allocated to the terminal device, and a beam configuration to be used for the selected beam is chosen based in part on user traffic and load distribution. A switching event is triggered. The switching event comprises producing the chosen beam configuration by providing a beamforming command and using a control line controlling a switch network comprised in phase shifters to steer the beam. The phase shifters are comprised in a radio frequency front-end unit comprising a plurality of antenna columns. The phase shifters are placed in front of selected antenna sub-arrays comprised in the plurality of antenna columns.
