Phase precompensation for multiple user-multiple input multiple output antenna mis-alignment

An apparatus, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• measure a first axis offset between a first antenna array of a first wireless device and a second antenna array of a second wireless device;
• measure a second axis offset between the first antenna array of the first wireless device and a third antenna array of a third wireless device;
• and
• perform multiple user-multiple input multiple output (MU-MIMO) communications with the second wireless device and the third wireless device using the first antenna array of the first wireless device, wherein performing the MU-MIMO communications includes applying a first phase precompensation based on the first axis offset to communications associated with the second wireless device and applying a second phase precompensation based on the second axis offset to communications associated with the third wireless device.

An apparatus, comprising:

• means for measuring a first axis offset between a first antenna array of a first wireless device and a second antenna array of a second wireless device;
• means for measuring a second axis offset between the first antenna array of the first wireless device and a third antenna array of a third wireless device;
• and
• means for performing multiple user-multiple input multiple output (MU-MIMO) communications with the second wireless device and the third wireless device using the first antenna array of the first wireless device, wherein performing the MU-MIMO communications includes applying a first phase precompensation based on the first axis offset to communications associated with the second wireless device and applying a second phase precompensation based on the second axis offset to communications associated with the third wireless device.

A non-transitory computer-readable medium storing code, the code comprising instructions executable by a processor to:

• measure a first axis offset between a first antenna array of a first wireless device and a second antenna array of a second wireless device;
• measure a second axis offset between the first antenna array of the first wireless device and a third antenna array of a third wireless device;
• and
• perform multiple user-multiple input multiple output (MU-MIMO) communications with the second wireless device and the third wireless device using the first antenna array of the first wireless device, wherein performing the MU-MIMO communications includes applying a first phase precompensation based on the first axis offset to communications associated with the second wireless device and applying a second phase precompensation based on the second axis offset to communications associated with the third wireless device.
