Abstract: Embodiments provide a method for transmitting a reference signal between a base station and a terminal. In this method, a parameter is determined by a terminal based on frequency domain location information of a frequency domain resource unit. The parameter is used to determine a sequence of the reference signal, and the reference signal is carried on the frequency domain resource unit. The reference signal can be sent to the base station by the terminal. In some embodiments, the reference signal sent by the base station can be received by the terminal. According to this method, a peak-to-average power ratio when a single terminal sends data to a base station can be reduced, and communication interference between different cells can be canceled or reduced as much as possible.

Abstract: This application provides a semiconductor switch device, a manufacturing method thereof, and a solid-state phase shifter. The semiconductor switch device includes a first semiconductor layer, intrinsic layers, and second semiconductor layers that are stacked. There are at least two intrinsic layers. The second semiconductors are in a one-to-one correspondence with the intrinsic layers, and each second semiconductor layer is stacked on a side of a corresponding intrinsic layer away from the first semiconductor layer. The first semiconductor layer forms one PIN diode together with each first intrinsic layer and each second semiconductor layer. Any two adjacent PIN diodes are electrically isolated. Automatic parameter matching between the two PIN diodes is implemented by using a geometrically symmetric figure with centers of the two PIN diodes aligned, to improve linearity. In addition, the entire semiconductor switch device has a compact structure, to improve an integration degree and reduce costs.
