Title: Method and apparatus for triggering power headroom reporting for multiple path loss references in wireless communication system
Inventor: LIN KO-CHIANG
IPC: H04W24/10
Filed: 2019-04-26
Abstract: To provide a method and an apparatus for triggering power headroom reporting for multiple path loss references.SOLUTION: In the method, a UE derives a first path loss value from a first path loss reference of a serving cell. The first path loss value is used to derive a power headroom value included in a first power headroom report 2205. After deriving the first path loss value, the UE derives a second path loss value from a second path loss reference of the serving cell. The second path loss reference is used for power control for a first physical uplink shared channel (PUSCH) transmission on the serving cell 2210. The UE derives a path loss change on the basis of the first path loss value and the second path loss value 2215. The UE determines whether a second power headroom report is triggered on the basis of whether the path loss change is greater than the threshold 2220.SELECTED DRAWING: Figure 22

Abstract: To improve followability with respect to high-speed rotation of a motor while suppressing a dead zone.SOLUTION: A motor control device comprises an acquisition section, a calculation section and a determination section. The acquisition section acquires coordinate information relating to a d-q current based on a 3-phase AC current flowing to a motor. In a case where a d-q voltage based on the coordinate information acquired by the acquisition section exceeds an upper limit voltage that can be outputted, the calculation section calculates a first voltage with which a q-axis voltage is settled at the upper limit voltage while fixing a d-axis voltage based on the coordinate information, and a second voltage with which the q-axis voltage is settled at the upper limit voltage while keeping a phase of the d-q voltage. The determination section determines a voltage command value for the settlement at the upper limit voltage based on the first voltage and the second voltage calculated by the calculation section.SELECTED DRAWING: Figure 2
