Method and devices for radar interference reduction

A controller for interference reduction in a radar unit, the controller comprising

• circuitry configured to receive one or more radar frames, wherein the one or more radar frames correspond to one or more respective time intervals during which the radar unit was activated to transmit and receive signals to produce data samples of the one or more radar frames,
• circuitry configured to determine whether the one or more radar frames have a higher presence of data samples that are subject to interference from other radar units in a first half of their corresponding time intervals than in a second, later, half of their corresponding time intervals,
• circuitry configured to postpone a scheduled time interval of an upcoming radar frame to be produced by the radar unit in case it is determined that the presence is higher in the first half of their corresponding time intervals, and
• circuitry configured to advance a scheduled time interval of an upcoming radar frame to be produced by the radar unit in case it is determined that the presence is higher in the second half of their corresponding time intervals, advancing a scheduled time interval of an upcoming radar frame to be produced by the radar unit.

A radar unit comprising a controller for interference reduction in a radar unit, the controller comprising:

• circuitry configured to determine whether the one or more radar frames have a higher presence of data samples that are subject to interference from other radar units in a first half of their corresponding time intervals than in a second, later, half of their corresponding time intervals,
• circuitry configured to postpone a scheduled time interval of an upcoming radar frame to be produced by the radar unit in case it is determined that the presence is higher in the first half of their corresponding time intervals, and
• circuitry configured to advance a scheduled time interval of an upcoming radar frame to be produced by the radar unit in case it is determined that the presence is higher in the second half of their corresponding time intervals, advancing a scheduled time interval of an upcoming radar frame to be produced by the radar unit.

A non-transitory computer-readable medium having stored thereon computer code instructions adapted to carry out a method for interference reduction performed by a radar unit when executed by a device having processing capability, the method, comprising:

• receiving one or more radar frames, wherein the one or more radar frames correspond to one or more respective time intervals during which the radar unit was activated to transmit and receive signals to produce data samples of the one or more radar frames,
• determining whether the one or more radar frames have a higher presence of data samples that are subject to interference from other radar units in a first half of their corresponding time intervals than in a second, later, half of their corresponding time intervals,
• in case it is determined that the presence is higher in the first half of their corresponding time intervals, postponing a scheduled time interval of an upcoming radar frame to be produced by the radar unit, and
• in case it is determined that the presence is higher in the second half of their corresponding time intervals, advancing a scheduled time interval of an upcoming radar frame to be produced by the radar unit.
