A signal transmission method includes: a terminal device receives configuration information of a positioning reference signal and configuration information of a first reference signal that are from a first network device and that are sent by a serving base station, where the first reference signal and the positioning reference signal are quasi-co-located (QCLed); the terminal device determines, based on the configuration information of the positioning reference signal and the configuration information of the first reference signal, whether a second reference signal corresponding to the first reference signal exists; and if determining that the second reference signal exists, the terminal device receives the positioning reference signal sent by the first network device, where the positioning reference signal and the second reference signal are QCLed.

Signal transmission method and apparatus for obtaining positioning reference signal

This application provides a communication method and a communications device. The method includes: determining configuration information of a plurality of synchronization signal blocks located at different frequency domain positions on one carrier, where the configuration information indicates configuration parameters of the plurality of synchronization signal blocks, the configuration parameter comprises configuration pattern indication information, and the configuration pattern indication information indicates synchronization signal blocks actually sent; and sending the configuration information to a terminal device.

Communication method and communications device

Example reference signal notification methods and apparatus are described. One example method includes sending a reference signal notification message by a network device, where the reference signal notification message includes time resource information of a reference signal. According to the embodiments of the present specification, the reference signal notification message is used to notify user equipment (UE) of a reference signal configuration, especially information about a channel state information reference signal (CSI-RS).

Reference signal notification method and apparatus

The method includes: determining, by a first communications device, a first BWP for each second communications device in a second communications device group, where the second communications device group includes two or more second communications devices, and the first BWPs of all the second communications devices in the second communications device group are the same; sending, by the first communications device, configuration information of the first BWP to each second communications device in the second communications device group; and sending, by the first communications device, control signaling to all the second communications devices in the second communications device group, where the control signaling is used to indicate all the second communications devices in the second communications device group to activate the first BWP.

Resource configuration method, first communications device, second communications device, and system

A signal transmission method and an apparatus are disclosed. In an embodiment a signal transmission method includes generating a reference signal and sending the reference signal, wherein the reference signal is sent in a specific time-frequency resource, and the specific time-frequency resource is located on symbols corresponding to a synchronization signal block.

Demodulation reference signal transmission method and apparatus

A sidelink communication method, a terminal device, and a network device are provided. In some embodiments, a terminal device receives resource configuration information sent by a network device, where the resource configuration information is for configuring a common resource for the terminal device, and the common resource is a resource that is configured by the network device for all terminal devices within coverage of the network device and that is to be used by all the terminal devices to perform sidelink communication. The terminal device receives sidelink BWP indication information sent by the network device, where the sidelink BWP indication information indicates N sidelink bandwidth parts SL-BWPs, and the N SL-BWPs include a frequency domain resource corresponding to the common resource, where N is a positive integer. The terminal device performs sidelink communication with another terminal device in the N SL-BWPs.

Sidelink communication method, terminal device, and network device

This application provides a wireless communication method, an apparatus, and a computer-readable storage medium. The method includes: A terminal receives a system message that is broadcast by an access network device on a physical broadcast channel PBCH, where the system message includes an extension field, and the extension field is used to indicate a format of the system message. The terminal discards the system message if information about the extension field is first information, where the first information is used to indicate that the format of the system message is an extended format. In this way, the terminal can select a proper manner to correctly process the system message.
