Abstract: This application provides a paging message transmission method and apparatus, where the method includes: receiving, by a terminal device, a physical downlink control channel (PDCCH) from a network device, where one or more types of first indication information, second indication information, a short message, and scheduling information of a paging message are carried on the PDCCH, the first indication information is used to indicate that the PDCCH carries the short message and/or the scheduling information, and the second indication information is used to indicate whether the scheduling information of the paging message is valid and/or whether the terminal device needs to receive a physical downlink shared channel (PDSCH); and obtaining, by the terminal device based on the PDCCH, one or more types of the information carried on the PDCCH.

Abstract: Embodiments of this application disclose a backscatter communication method and a related apparatus. The method includes: An excitation device determines a first sequence, generates a first signal, and sends the first signal, where the first signal carries the first sequence; after receiving the first signal, a backscatter device modulates backscatter device data onto the received first signal to obtain a second signal, and backscatters the second signal, to implement first scrambling on the backscatter device data by using the first sequence; and a receiving device determines the first sequence, receives the second signal from the backscatter device, and demodulates the received second signal based on the first sequence, to obtain the backscatter device data carried on the second signal.

Abstract: This application relates to the field of communications technologies. A method includes: A first device receives first configuration information sent by a second device. The first configuration information includes at least one of information about a reference signal, frequency range information of a radio frequency signal, or bandwidth range information. The first device measures a first reference signal set, to obtain a first measured value. The first reference signal set includes at least two reference signals. The first device determines an expansion factor α based on the first configuration information. The first device determines a second measured value based on the first measured value and the expansion factor α.
