Abstract: 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.

Abstract: Embodiments of this application provide a communication method and a communications apparatus. Therefore, when an operating bandwidth of a terminal device is a narrow bandwidth, time-frequency synchronization is performed on a resource with a relatively small bandwidth, to implement network communication. This avoids a communication failure and improves communication efficiency. In the method, a network device sends first indication information to a terminal device, where the first indication information indicates a relative location between a first resource and a second resource, the first resource carries a synchronization signal block, the synchronization signal block includes a first system message, the second resource carries a second system message, and a bandwidth of the second resource is less than a bandwidth of the first resource.

Abstract: In a resource allocation method, after determining a BWP allocated to a terminal device, where the BWP includes a first BWP, and determining a first value, a network device sends first indication information to the terminal device, where the first indication information is used to indicate the first value. The terminal device determines the BWP allocated by the network device to the terminal device, where the BWP includes the first BWP, and receives the first indication information from the network device. Then, when the first value is used to indicate a RBG size corresponding to the first BWP, the RBG size corresponding to the first BWP is determined based on the first value. Alternatively, when the first value is used to determine a RIV set corresponding to the first BWP, the RIV set corresponding to the first BWP is determined based on the first value.

Abstract: This application provides example communication methods and apparatuses. One example method includes performing, by a network device on a preconfigured resource, data demodulation on uplink data from a terminal device. The network device can then send downlink control information (DCI) to the terminal device, where the DCI includes first indication information, and if the uplink data fails to be demodulated, or it is determined, based on a result of the data demodulation, that the terminal device needs to retransmit the uplink data, the first indication information indicates either the terminal device to initiate random access or EDT and retransmit the uplink data or that the uplink data fails to be demodulated.

Abstract: This application provides a resource configuration method. The method includes: generating, by a network device, a first signal; and sending, by the network device, the first signal to a terminal device at a target resource location. The target resource location includes at least one subframe, and the at least one subframe is an invalid subframe. This implements that the network device sends the first signal in the invalid subframe. Based on a mechanism of the invalid subframe, a terminal device that does not need to receive the first signal may postpone the invalid subframe, and a terminal device that needs to receive the first signal may receive the first signal in the invalid subframe.
