Abstract: A method for computing an estimated data availability for UCI (Uplink Control Information) in an LTE or 5G system enables a base station (e.g., eNodeB or gNodeB) to estimate how much data is available within its allocated PUSCH (Physical Uplink Shared Channel) data for the UCI data. The method enables a UE to insert a sufficient amount of UCI data without consuming resources required for the PUSCH data, thereby preventing decode failures.

Abstract: A method for quickly determining the rotor position of a permanent magnet motor using the N-division approach is provided. The method involves converting the motor's three-phase stator current coordinates into the dq two-phase synchronous rotation coordinate system and identifying the initial rotor position area. By establishing a stator current cost model and utilizing the d-axis stator current, the initial rotor position can be obtained. Subsequently, the N-division approach is employed for iterative optimization to obtain the estimated rotor position and the final position region, leading to a rapid estimation of the permanent magnet motor's rotor position. This method incorporates the finite set model predictive control concept into a phase-locked loop based on stator current, eliminating the need for additional rotor position polarity judgment and invalid rotor position control variables.
