Abstract: This application discloses a protection circuit associated with a battery management system (BMS). The protection circuit includes a first protection module and a freewheeling module. The first protection module is connected in parallel to a first switch module of the BMS, and the freewheeling module is connected in parallel to a load module of the BMS. The first protection module switches to a charging state when the first switch module is turned off to stabilize a voltage between a first terminal of the first switch module and a second terminal of the first switch module. The freewheeling module is turned on when the first switch module is turned off to stabilize a voltage between the first switch module and the second switch module. The protection circuit mitigates risks of breakdown of the first switch module, and prevents a parasitic inductance from limiting a switching frequency of the first switch module.

Abstract: Embodiments disclosed relate to apparatuses, systems, and methods for improved handling of phase noise (PN) in millimeter wave (MMW or mmWave) communications in a wireless communication system, such as 5G NR. When severe phase noise is present in a communication link, the link performance can be substantially degraded. Thus, it would be desirable to utilize techniques to compensate for phase noise in mmWave communications. In Rel-15, a Phase Tracking Reference Signal (PT-RS or PTRS) was specified for both downlink and uplink communications, specifically for Cyclic Prefix-Orthogonal Frequency Division Multiplexing (CP-OFDM) and Discrete Fourier Transform spread Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). However, prior art approaches to PTRS using block-based pilot allocation schemes required complicated receiver processing.
