Abstract: A PTRS processing method includes: receiving, by a terminal, first indication information and second indication information from a network device, where the first indication information is used to indicate a time-domain location at which a PTRS is to be sent by the terminal, and the second indication information is used to indicate an offset of an initial time-domain location to which the PTRS is mapped by the terminal; mapping, by the terminal, the PTRS to one or more DFT-s-OFDM symbols based on the first indication information and the second indication information; and sending, by the terminal, the one or more DFT-s-OFDM symbols. In this way, the PTRS mapped to the DFT-s-OFDM symbol is offset at a DFT-s-OFDM symbol level.

Abstract: The present disclosure provides a downlink data transmission method, including: using a time-division multiplexing transmission mode in one transmission time interval; sending, by using a wide beam, a control signal to a user served in the current transmission time interval; and grouping users and sending data signals to different user groups by using different narrow beams. In one transmission time interval, time-division multiplexing is used, and a wide beam and a narrow beam are respectively used to transmit a control signal and a data signal. This can avoid a throughput bottleneck resulting from use of a transmission scheme that is based on frequency-division multiplexing only.

Abstract: This application discloses example power control methods and apparatuses. One example method includes receiving, by a first node, first information sent by a second node, where the first information is used to determine a first transmit power, where the first transmit power is a power used when the first node sends downlink information to the second node through a first link, where the first link is a link between the first node and the second node, and where the first node is an upper-level device of the second node. The first node can then determine the first transmit power based on the first information.

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.
