摘要： This application provides a power control method and apparatus, to perform power control in a communication system integrating terrestrial communication with satellite communication. In the method, a first uplink transmit power used when a terminal device communicates with a source network device is adjusted based on a first parameter, to obtain a second uplink transmit power, and the second uplink transmit power is used to communicate with a target network device in a handover process. Based on the foregoing description, in this embodiment of this application, when a path loss between the terminal device and the source network device is different from a path loss between the terminal device and the target network device, an uplink power used when the terminal device communicates with the target network device can be controlled in the handover process of the terminal device.

摘要： The present invention provides an information transmission method, an apparatus, and a system. A first base station may identify, according to indication information, global information and local information in uplink information sent by user equipment; and if the indication information indicates that the uplink information includes the global information, uploads the global information to a core network device; or if the indication information indicates that the uplink information includes the local information, directly delivers the local information to a neighboring base station, so that the neighboring base station can deliver the local information to user equipment in a cell covered by the neighboring base station, thereby shortening a transmission path of data information, reducing a transmission delay of the data information, and improving a transmission speed of the data information. Because the local information does not need to be forwarded by a core network, a transmission delay of the local information is reduced, and a delay of a communications system is reduced. In addition, load of the core network can also be alleviated when the local information is not processed by using the core network.

The method includes: A terminal device receives a first broadcast signal block of a first satellite (210); the terminal device obtains a measurement value of the first broadcast signal block (220); the terminal device obtains positioning assistance information from the first satellite (230), where the positioning assistance information indicates information about a second satellite, the information about the second satellite includes a frequency and a polarization direction of the second satellite, a frequency and/or a polarization direction of the first satellite are/is different from the frequency and the polarization direction of the second satellite; the terminal device receives a second broadcast signal block of the second satellite based on the positioning assistance information (240); the terminal device obtains a measurement value of the second broadcast signal block (250); and the terminal device obtains location information of the terminal device based on the measurement value of the first broadcast signal block and the measurement value of the second broadcast signal block (260). The terminal device obtains measurement values of broadcast signal blocks by measuring the broadcast signal blocks sent by at least two satellites on respective planned frequencies and in respective planned polarization directions, to use the broadcast signal blocks as a positioning reference signal for positioning. In this way, the satellite network no longer needs to broadcast a dedicated positioning reference signal. The terminal device may implement passive positioning of the terminal device based on the measurement values of the broadcast signal blocks of the at least two satellites, so that bandwidth resource overheads can be reduced.
