Abstract: A terminal device sends at least one piece of relative position information to a network side device, where the relative position information is information about a relative position between any two of a plurality of tags supported by the terminal device. The terminal device measures, by using the plurality of tags, a reference signal sent by the network side device, to obtain reference signal measurement information corresponding to the plurality of tags. The terminal device sends, to the network side device, the reference signal measurement information corresponding to the plurality of tags.

Abstract: A scheduling method implements flexible scheduling in a relay network. A method includes: determining, by a first device, information about a transmission time difference, where the transmission time difference is a time difference between a control channel of a first link and a data channel that is of the first link and that is scheduled by the control channel of the first link; notifying a second device of the information about the transmission time difference; and performing, by the second device, scheduling based on the information about the transmission time difference. In this way, the second device determines whether a resource needs to be reserved for the data channel of the first link, and it is possible that a time division resource, a frequency division resource, or a space division resource is shared for data of the first link and data of a second link.

Abstract: A first apparatus establishes a first radio link control RLC entity and a second RLC entity, where the first RLC entity and the second RLC entity are associated with a first packet data convergence protocol PDCP entity. The first apparatus sends first data through the first RLC entity and/or the second RLC entity. The first RLC entity corresponds to a unicast transmission mode, and the second RLC entity corresponds to a multicast transmission mode.

Abstract: This application provides a communication method, an apparatus, and a communications system, and relates to the field of communications technologies. A terminal device receives system information broadcast by a network device, and determines a bandwidth of an initial BWP based on the system information. The system information includes first indication information. The first indication information indicates that the bandwidth of the initial BWP used for the terminal device is a first bandwidth or a second bandwidth. The first bandwidth is indicated by using a first bandwidth parameter carried in the system information. The second bandwidth is a bandwidth of a CORESET 0. The CORESET 0 is used to schedule the system information.

Abstract: A signal transmission method and apparatus are provided. The method includes: obtaining, by a transmitter, a to-be-sent data block; inserting one or more pilot blocks among a plurality of pieces of data of the to-be-sent data block based on an agreed position; and sending, by the transmitter, the to-be-sent data block into which the one or more pilot blocks are inserted. Inserting the one or more pilot blocks among the plurality of pieces of data of the to-be-sent data block can improve a phase noise compensation effect for a receiver without increasing pilot overheads.

Abstract: This application provides a measurement method and an apparatus. In the measurement method, a communications apparatus may receive configuration information, where the configuration information includes a cell list and indication information, and the indication information is used to indicate whether a measurement event is affected by the cell list; and the communications apparatus performs a measurement evaluation based on the cell list and the indication information. In this implementation, whether to perform a trigger evaluation for a measurement result of a cell in the cell list may be determined depending on whether the measurement event is affected by the cell list, to avoid an unnecessary trigger evaluation for a cell.
