Title: Drive circuit with zero-crossing detection function, and zero-crossing detection method
Inventor: LI JIN
IPC: H02M1/08
Filed: 2017-12-29
Abstract: A drive circuit with a zero-crossing detection function, and a zero-crossing detection method. The drive circuit comprises: a power switch tube (NM) that controls an output voltage and couples a drop signal; a pull-up drive tube (21) for providing a pull-up current; and a first pull-down drive tube (22) and a second pull-down drive tube (23) for respectively providing a first and second pull-down current. When an inductor starts to discharge, the first pull-down current and the second pull-down current jointly pull down a gate end of the power switch tube (NM), such that the power switch tube (NM) is in a cut-off state; after a set time, the first pull-down current is turned off; and when the inductor ends discharging, a parasitic capacitance of the power switch tube (NM) couples with the drop signal, and when the drop signal is detected, the pull-up current pulls up the gate end of the power switch tube (NM), such that the power switch (NM) is in a turning-on state.

IPC: H04W72/10
Filed: 2018-07-13
Abstract: According to some embodiments, a base station (BS) transmits a first allocation of a plurality of channel subsets to user equipments (UEs) for contention transmission of the UEs to the BS. The first allocation allocates one or more channel subsets to each UE so that each UE can only contend for channels within a channel subset allocated to the UE using a contention-based mechanism. In response to receipt of the first allocation, one or more UEs send requests to the BS requesting for access of channels for uplink transmissions determined by the one or more UEs. The BS determines, based on at least the requests sent by the UEs, channels to be allocated to the UEs for performing uplink transmissions, and sends a second allocation indicating the allocated channels. The UEs then perform uplink transmissions based on the second allocation.
