Base station antenna array orientation calibration for cellular positioning

A network entity, comprising:

• a memory;
• at least one transceiver;
• and
• at least one processor communicatively coupled to the memory and the at least one transceiver, the at least one processor configured to:
• determine a location of a target base station and a location of at least one reference device;
• determine an angle-of-arrival (AoA) measurement of one or more reference signals received by at least one antenna array of the target base station from the at least one reference device;
• determine an expected AoA between the at least one antenna array and the at least one reference device based on the location of the target base station and the location of the at least one reference device;
• and
• determine an orientation offset of the at least one antenna array based on a difference between the expected AoA and the AoA measurement.

A network entity, comprising:

• means for determining a location of a target base station and a location of at least one reference device;
• means for determining an angle-of-arrival (AoA) measurement of one or more reference signals received by at least one antenna array of the target base station from the at least one reference device;
• means for determining an expected AoA between the at least one antenna array and the at least one reference device based on the location of the target base station and the location of the at least one reference device;
• and
• means for determining an orientation offset of the at least one antenna array based on a difference between the expected AoA and the AoA measurement.

A non-transitory computer-readable medium storing computer-executable instructions that, when executed by a network entity, cause the network entity to:

• determine a location of a target base station and a location of at least one reference device;
• determine an angle-of-arrival (AoA) measurement of one or more reference signals received by at least one antenna array of the target base station from the at least one reference device;
• determine an expected AoA between the at least one antenna array and the at least one reference device based on the location of the target base station and the location of the at least one reference device;
• and
• determine an orientation offset of the at least one antenna array based on a difference between the expected AoA and the AoA measurement.
