Apparatus, method and computer program for determining beamforming direction

A method, comprising:

• receiving at least one signal from at least one transmitter;
• determining at least one parameter of the at least one signal;
• determining, based on the at least one parameter, which of a plurality of stored differential signal reception radiation patterns the received signal corresponds to, the plurality of stored radiation patterns associated with a direction of arrival;
• and
• aligning an antenna beam to the transmitter based on the direction of arrival associated with the determined stored differential signal reception radiation pattern.

A computer program embodied on a non-transitory computer-readable medium, said computer program comprising instructions for causing an apparatus to perform at least:

• receiving at least one signal from at least one transmitter;
• determining at least one parameter of the at least one signal;
• determining, based on the at least one parameter, which of a plurality of stored differential signal reception radiation patterns the received signal corresponds to, the plurality of stored radiation patterns associated with a direction of arrival;
• and
• aligning an antenna beam to the transmitter based on the direction of arrival associated with the determined stored differential signal reception radiation pattern.

An apparatus comprising:

• at least one processor;
• and
• at least one memory including computer program code;
• the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
• receive at least one signal from at least one transmitter;
• determine at least one parameter of the at least one signal;
• determine, based on the at least one parameter, which of a plurality of stored differential signal reception radiation patterns the received signal corresponds to, the plurality of stored radiation patterns associated with a direction of arrival;
• and align an antenna beam to the transmitter based on the direction of arrival associated with the determined stored differential signal reception radiation pattern.
