Abstract
A method performed by a first node for selecting a beam for a data transmission between a Multiple In Multiple Out (MIMO) antenna system used by the first node, and a second node in a wireless communications system is provided. The first node obtains (202) a direction from a reference point of the MIMO antenna system to the second node, based on location data defining a location of the second node. The first node then selects (204) a beam among available beams in the MIMO antenna system for a subsequent transmission to or from the second node. The beam is selected such that an angle between the obtained direction and a main lobe direction of the beam that is selected provides the smallest angle among the available beams in the MIMO antenna system.

A method, performed by a first node, for selecting a beam for a data transmission between a Multiple In Multiple Out (MIMO) antenna system used by the first node and a second node in a wireless communications system, the method comprising the first node:
- obtaining a direction from a reference point of the MIMO antenna system to the second node, based on location data defining a location of the second node;
- selecting a beam among available beams in the MIMO antenna system for a subsequent transmission to or from the second node, wherein the beam that is selected is selected such that an angle between the obtained direction and a main lobe direction of the beam that is selected provides the smallest angle among the available beams in the MIMO antenna system.
A non-transitory computer readable recording medium storing a computer program product for controlling first node for selecting a beam for a data transmission between a Multiple In Multiple Out (MIMO) antenna system used by the first node and a second node in a wireless communications system, the computer program product comprising program instructions which, when run on processing circuitry of the first node, causes the first node to:
- obtain a direction from a reference point of the MIMO antenna system to the second node, based on location data defining a location of the second node;
- select a beam among available beams in the MIMO antenna system for a subsequent transmission to or from the second node, wherein the beam that is selected is selected such that an angle between the obtained direction and a main lobe direction of the beam that is selected provides the smallest angle among the available beams in the MIMO antenna system.
A first node configured to select a beam for a data transmission between a Multiple In Multiple Out (MIMO) antenna system used by the first node and a second node in a wireless communications system, the first node comprising:
- processing circuitry;
- memory containing instructions executable by the processing circuitry whereby the first node is operative to:
- obtain a direction from a reference point of the MIMO antenna system to the second node, based on location data defining a location of the second node;
- select a beam among available beams in the MIMO antenna system for a subsequent transmission to or from the second node, which beam is selected such that an angle between the obtained direction and a main lobe direction of the beam that is selected provides the smallest angle among the available beams in the MIMO antenna system.
