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 relates to the field of communications technologies and discloses a signal transmission method and device, and a system. The method includes: determining, by a first device after receiving first information transmitted by a second device, to perform at least one of interference measurement and channel measurement on a resource, or to transmit a reference signal on a resource. The second device can configure the resource of the reference signal for the first device by transmitting the first information to the first device that is in a transmitting state or a receiving state, thereby improving flexibility of resource configuration of the reference signal.

Abstract: A package structure and an electronic apparatus includes a power semiconductor device, a wire, and a shape memory object. The wire is electrically connected to the power semiconductor device, the shape memory object is in contact with the wire, and the shape memory object is configured to deform when temperature of the shape memory object is not less than preset temperature, to enable a current in the wire to be cut off or reduced. In this way, impact of high temperature generated by the power semiconductor device when an overcurrent occurs in the power semiconductor device on the printed circuit board is reduced, a possibility that a printed circuit board is damaged is greatly reduced, and an overcurrent self-protection capability of the package structure is implemented.

Abstract: Example interference measurement methods and apparatus are described. One example method includes that a terminal device receives configuration information of an interference measurement resource from a network side device. The terminal device performs first interference measurement by using a first measurement resource. The first measurement resource is a proper subset of the interference measurement resource. A quantity of resource elements of the first measurement resource that are located in a same symbol is M, where M≥2. A spacing in frequency domain between two adjacent resource elements of the M resource elements of the first measurement resource that are located in the same symbol is more than one subcarrier.

Abstract: This application discloses a resource indication method, a network device, and a terminal device, to improve utilization of a resource mapped to a DMRS port. The method includes: sending, by a network device, configuration information to a terminal device, so that the terminal device determines, based on the configuration information, that a second resource in first resources is used to transmit first information or that a third resource in first resources is not used to transmit first information, where the first resources are resources mapped to a DMRS port. In this way, the terminal device can multiplex the resources mapped to the DMRS port. When some of the first resources are not used to transmit a DMRS, the resources may be indicated to determine whether the resources may be used to transmit the first information, for example, the first information may be data, control information, or other information different from DMRS information, thereby ensuring maximum use of the resources mapped to the DMRS port, and improving resource utilization.
