  • Publication number: 20240162964
    Abstract: A method of spatial modulation using an antenna array including radiating elements having power amplifiers communicatively coupled thereto. An amplitude of an output signal to be formed in space is determined by the antenna array based on an input signal. Output amplitude levels for the radiating elements are determined based on the amplitude of the output signal and a current output amplitude level of the antenna array. The first signal(s) for a first subarray of the antenna array and the second signal(s) for a second subarray of the antenna array are generated based on the input signal. The output amplitude levels are assigned to the power amplifiers of the radiating elements. The first signal(s) are sent to radiating elements of the first subarray and the second signal(s) are sent to radiating elements of the second subarray for transmission therefrom to form a combined signal in space as the output signal.

  • Patent number: 11983631
    Abstract: A computer determines a solution to a nonlinear optimization problem. A conjugate gradient (CG) iteration is performed with a first order derivative vector and a second order derivative matrix to update a CG residual vector, an H-conjugate vector, and a residual weight vector. A CG solution vector is updated using a previous CG solution vector, the H-conjugate vector, and the residual weight vector. An eigenvector of the second order derivative matrix having a smallest eigenvalue is computed. A basis matrix is defined that includes a cubic regularization (CR) solution vector, a CR residual vector, the CG solution vector, the CG residual vector, and the eigenvector. A CR iteration is performed to update the CR solution vector. The CR residual vector is updated using the first order derivative vector, the second order derivative matrix, and the updated CR solution vector. The process is repeated until a stop criterion is satisfied.

  • Publication number: 20240154682
    Abstract: Aspects relate to measuring and scheduling reference signals. A user equipment (UE) detects reference signals having overlapping resources, and determines a context associated with the reference signals. A Layer 1 (L1) measurement is then performed of at least one reference signal according to a prioritization associated with the context. In another aspect, a network entity determines a scheduling of resources that enables a UE to prioritize performing an L1 measurement of a reference signal from a non-serving cell, and communicates with the UE according to the scheduling. In yet another aspect, a UE communicates with a gNb using transmission configuration indication (TCI) states associated with a corresponding control resource set (CORESET) pool of CORESETs. Beam failure detection (BFD) reference signals are then identified explicitly via a configuration signaling, or implicitly based on the TCI states. The BFD reference signals are then monitored to facilitate detecting a beam failure event.
