Abstract: A carrier frequency tracking method, a signal transmission method, and a related apparatus. The carrier frequency tracking method includes: a terminal device receives a first tracking reference signal from a first transmission reception apparatus of a single frequency network cell; the terminal device receives a second tracking reference signal from a second transmission reception apparatus of the single frequency network cell, where the first tracking reference signal and the second tracking reference signal occupy different time-frequency resources; and the terminal device performs carrier frequency tracking based on at least one of the first tracking reference signal and the second tracking reference signal.

Abstract: The present disclosure discloses an example communication method and apparatus. One example communication method includes receiving, by a first node, decoding information and coded data from a second node, where the coded data is obtained after data of a node group in which the first node is located is encoded, the data of the node group includes data expected to be received by at least two nodes in the node group, and the at least two nodes include the first node. Data expected to be received by the first node is obtained by the first node based on the decoding information and the coded data.

Abstract: A signal demodulation method, a signal transmission method, and a related apparatus. The signal demodulation method includes: a terminal device receives a first tracking reference signal from a first transmission reception apparatus of a single frequency network cell; a second tracking reference signal occupying different time-frequency from the first tracking reference signal from a second transmission reception apparatus of the single frequency network cell; and receives indication information indicating tracking reference signals from the first transmission reception apparatus or the second transmission reception apparatus; determines, based on the one or more tracking reference signals for receiving the downlink signal, a first carrier frequency on which the downlink signal is to be received; receives the demodulation reference signal and the downlink data based on the first carrier frequency; and demodulates the downlink data based on the demodulation signal.

Abstract: A communication method and apparatus improve accuracy of correcting a frequency offset. Configuration information received from a network device provides for configuring one or more uplink reference signal resources each including a first time unit and a second time unit. The first time unit includes a first antenna port. The second time unit includes a second antenna port. An uplink reference signal is sent to the network device based on the configuration information.

Abstract: This application provides a data sending method and apparatus. The method includes: A node generates a first modulation symbol corresponding to a first modulation scheme. The node quantizes the first modulation symbol to obtain a target symbol. The target symbol corresponds to one of a plurality of constellation points of a second modulation scheme. The node preprocesses the target symbol to obtain to-be-sent data. The preprocessing includes one or more of layer mapping, antenna port mapping, precoding, or transform precoding. The node maps the to-be-sent data to a physical resource, and sends the to-be-sent data by using the physical resource.

Abstract: This application provides a data sending method and an apparatus. The method includes performing, by a node, soft modulation to generate a modulation symbol. The method also includes preprocessing, by the node, the modulation symbol to obtain to-be-sent data. The preprocessing includes one or more of layer mapping, antenna port mapping, precoding, or transform precoding. The method further includes mapping, by the node, the to-be-sent data to a physical resource, and sending the to-be-sent data by way of the physical resource.
