Abstract: In a signal transmission method and apparatus, a network device sends scheduling information of at least one of two carriers whose communication directions are opposite on a target OFDM symbol; a terminal device performs channel transmission of a target carrier on the target OFDM symbol based on the scheduling information, where the target carrier is one of carriers that are of the two carriers whose communication directions are opposite and that have channel transmission on the target OFDM symbol; and the network device performs channel transmission on the target OFDM symbol and the target carrier. A time domain resource may be allocated to a carrier on which transmission scheduling is currently performed, thereby improving transmission resource utilization and reducing a waiting delay.

Abstract: This application discloses a communication method, a communication device, and a communication system, and relates to the field of communication technologies, to resolve a problem that a network device cannot perform adaptive adjustment on a downlink communication link in a highly-reliable and low latency communication technology. In a solution provided in this application, after receiving downlink data from a network device, a terminal device may determine information about whether M (M is a positive integer) pieces of downlink data (that is, a first information set) are successfully parsed, and further feed back, to the network device, information obtained by the terminal device by parsing N (N is a positive integer, and N≤M) pieces of downlink data (that is, second information), so that the network device can perform adaptive adjustment on a downlink based on the second information, thereby ensuring reliability of next downlink transmission.

Abstract: A resource mapping method and a communication apparatus include a communication device that determines whether a first information block corresponds to one or more modulation symbols, and determines whether a second information block corresponds to one or more modulation symbols, where the first information block and the second information block are transmitted through a same physical channel, the first information block and the second information block correspond to a total of M modulation symbols, and the physical channel includes N spatial resources. The communication device maps the M modulation symbols to the N spatial resources, where N and M are integers greater than or equal to 2. The modulation symbols obtained by independently coding and modulating the different information blocks are mapped to the plurality of spatial resources of the physical channel.

Abstract: This application provides an interference tracking method and an apparatus. A first terminal receives second information from a second network device on a first time-frequency resource, measures interference from the second network device based on the second information, and feeds back first interference information obtained through measurement to a first network device. Because the second information is sent by the second network device (that is, an interference source), the method enables the first terminal to measure interference in a timely manner based on an interference change of the interference source, accurately track an interference change caused by the second network device, and report more accurate interference information to the first network device.

Abstract: This application provides a communication method and apparatus, and relates to the field of communication technologies. A terminal receives first indication information that is sent by a network device and that indicates a time-frequency resource and an MCS of first data, and determines a first time-frequency resource carrying the first data, a second time-frequency resource carrying second data, and an MCS of the second data. The time-frequency resource includes the first time-frequency resource and the second time-frequency resource. In the method, if there are two pieces of data, the terminal may determine time-frequency resources and MCSs of the two pieces of data, to meet different data requirements and flexibly perform data transmission.
