摘要： A signal transmission method, a device, and a system relate to the field of wireless communications technologies, and are used to reduce power consumption generated when a terminal device obtains a paging indication message. The method includes: determining, by a base station, a first parameter; sending the determined first parameter to a terminal device by using a system message and/or higher layer signaling; and sending a first signal to the terminal device based on the first parameter, where the first signal is used to indicate a paging status of the terminal device, and the first parameter includes information used to indicate a resource location of the first signal; and receiving, by the terminal device, the first parameter sent by the base station by using the system message and/or higher layer signaling, receiving the first signal based on the first parameter, and determining the paging status of the terminal device based on the first signal. A manner of sending the first signal by the base station avoids a case in which the terminal monitors a PDCCH to determine the paging status of the terminal. Therefore, power consumption of the terminal device is reduced to some extent.

摘要： Embodiments of this application provide a method for transmitting positioning assistance data and a device. The method includes: receiving, by a network device, at least one positioning assistance data message sent by a positioning server, where the at least one positioning assistance data message is used to carry positioning assistance data; and broadcasting, by the network device, a system message to a terminal device, where the system message is used by the terminal device to obtain the positioning assistance data. According to the embodiments of this application, the network device broadcasts the system message to broadcast the positioning assistance data. In this way, a problem of low efficiency of transmitting existing centralized positioning assistance data can be resolved, and a problem in the prior art that a positioning server needs to perform signaling communication with each terminal device in a unicast transmission scenario can be avoided, thereby reducing signaling overheads.
