    Abstract: A data transmission method and an apparatus are provided. A transmit device sends a plurality of pieces of data, wherein different data in the data occupies different transmission resources. A first receive device in a multicast group receives the data; determines a first feedback message based on a decoding result of the data; feeds back the first feedback message to the transmit device which distinguishes, based on the first feedback message, which data in the plurality of pieces of data is correctly decoded by the multicast group and which data is not, wherein the first feedback message indicates whether the first receive device correctly decodes the data; and performs network encoding transmission on the incorrectly decoded data, thereby improving retransmission efficiency, reducing a delay, and saving feedback resources.

    Abstract: This application discloses a reference signal transmission method and an apparatus. A network node sends reference signals by mapping the reference signals to at least one resource unit, where the at least one resource unit includes a plurality of sub-resource units; and the network node receives, from the terminal, measurement information related to part of the plurality of sub-resource units. The terminal selects, based on configuration information of the reference signals, part of the measurement information to report, so that a quantity of channel resources occupied by the measurement information is reduced.

    Abstract: This application provides a communication method, a terminal, and a network device. The method includes: receiving, by a terminal, indication information from a network device, where the indication information includes an identifier of at least one reference signal; and determining, by the terminal, that there is a correspondence between a resource used to send a first channel and a first reference signal of the at least one reference signal, where the first channel is a channel to be transmitted by the terminal, and there is a spatial quasi co-location (QCL) relationship between a port of the first channel and a port of the first reference signal, or there is a spatial QCL relationship between a port of a demodulation reference signal of the first channel and a port of the first reference signal.

    Abstract: This application provides a method for reporting port information, a terminal device, and a network device. The method includes: determining, by a terminal device, an uplink signal, where the uplink signal includes information about a phase tracking reference signal (PTRS) port of the terminal device, or the uplink signal includes information about the PTRS port and information about a demodulation reference signal (DMRS) port, or the uplink signal includes a correspondence between the PTRS port and the DMRS port; and sending, by the terminal device, the uplink signal to a network device. In embodiments of this application, the terminal device reports the uplink signal to the network device, so that the network device does not need to configure different PTRS ports for DMRS ports, to avoid configuring excessive PTRS ports, thereby saving PTRS port resources.

    Abstract: This application provides a communication method, a network device, and a relay device for relay devices to discover one another. A first network device determines a first resource, where the first resource includes a resource used by a second network device to send a first signal to a second relay device, or the first resource includes a resource configured by the second network device for a first signal with zero power. The first network device sends first configuration information to a first relay device, where the first configuration information is used by the first relay device to determine a second resource for sending a second signal, and the second resource is a part or all of the first resource.
