Radar sensing using adaptive phase-changing devices (apds)

A method of identifying radio transmission signal paths by a device in control of an adaptive phase-changing device (APD), the method comprising:

• transmitting, by the device, radar signals in a first plurality of directions;
• receiving, at the device, a reflection of at least part of the radar signals;
• identifying at least one blocking object position of at least one blocking object based on the reflection;
• transmitting, based on the at least one blocking object position and a position of the APD, the radar signals in a refined direction toward the APD;
• varying a phase-changing configuration of the APD to produce APD radar signals in a second plurality of directions for detecting an object;
• and
• ascertaining, based on a reflection of the APD radar signals from the object and the phase-changing configuration, a set of configuration parameters of a radio transmission signal path via the APD.

A user equipment (UE), comprising:

• one or more radio frequency (RF) modems;
• a processor coupled to the one or more RF modems;
• and
• at least one memory storing executable instructions, the executable instructions to manipulate at least one of the processor or the one or more RF modems to:
• transmit, by the UE, radar signals in a first plurality of directions;
• receive, at the UE, a reflection of at least part of the radar signals;
• identify at least one blocking object position of at least one blocking object based on the reflection;
• transmit, based on the at least one blocking object position and a position of an adaptive phase-changing device (APD), the radar signals in a refined direction toward the APD;
• vary a phase-changing configuration of the APD to produce APD radar signals in a second plurality of directions for detecting an object;
• and
• ascertain, based on a reflection of the APD radar signals from the object and the phase-changing configuration, a set of configuration parameters of a radio transmission signal path via the APD.

A network entity, comprising:

• one or more radio frequency (RF), modems;
• a processor coupled to the one or more RF modems;
• and
• at least one memory storing executable instructions, the executable instructions to manipulate at least one of the processor or the one or more RF modems to:
• transmit, by the network entity, radar signals in a first plurality of directions;
• receive, at the network entity, a reflection of at least part of the radar signals;
• identify at least one blocking object position of at least one blocking object based on the reflection;
• transmit, based on the at least one blocking object position and a position of an adaptive phase-changing device (APD), the radar signals in a refined direction toward the APD;
• vary a phase-changing configuration of the APD to produce APD radar signals in a second plurality of directions for detecting an object;
• and
• ascertain, based on a reflection of the APD radar signals from the object and the phase-changing configuration, a set of configuration parameters of a radio transmission signal path via the APD.
