Differential sensing for joint communications and sensing

A device, comprising:

• one or more memories;
• and
• one or more processors, coupled to the one or more memories, configured to:
• estimate targets and angle-of-arrival (AoA) and angle-of-departure (AoD) pairs for the targets based on a sensing-aware beam-forming (SABF) signal and a sensing-aware beam-nulling (SABN) signal received from another device,
• wherein, to estimate the targets and the AoA and AoD pairs for the targets, the one or more processors are configured to:
• calculate an eigenvalue decomposition of difference of autocorrelation matrices based on the SABF signal and the SABN signal,
• estimate a total quantity of positive eigenvalues of the eigenvalue decomposition of difference,
• calculate angular spectrums for the AoAs based on the total quantity of positive eigenvalues, and
• estimate the AoA and AoD pairs based on the angular spectrums for the AoAs;
• perform post-processing of the AoA and AoD pairs to modify estimation accuracies for the AoA and AoD pairs;
• estimate path loss values for paths of the targets;
• utilize a triangulation technique to determine positions of the targets based on the AoA and AoD pairs;
• and
• perform one or more actions based on the positions of the targets.

A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a device, cause the device to:
• estimate an angle-of-arrival (AoA) and angle-of-departure (AoD) pair for a target based on a sensing-aware beam-forming (SABF) signal and a sensing-aware beam-nulling (SABN) signal received from another device,
• wherein the one or more instructions, that cause the device to estimate the AoA and AoD pair for the target, cause the device to:
• calculate an eigenvalue decomposition of difference of autocorrelation matrices based on the SABF signal and the SABN signal;
• estimate a total quantity of positive eigenvalues of the eigenvalue decomposition of difference;
• calculate an angular spectrum for the AoA based on the total quantity of positive eigenvalues;
• and
• estimate the AoA and AoD pair based on the angular spectrum for the AoA;
• perform post-processing of the AoA and AoD pair to modify an estimation accuracy for the AoA and AoD pair;
• estimate a path loss value for a path of the target;
• determine a position of the target based on the AoA and AoD pair;
• and
• perform one or more actions based on the position of the target.
