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.

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.

Abstract: The present disclosure relates to communication methods, apparatus, and devices. In one example method, a terminal device receives first indication information, where the first indication information indicates a first frequency domain resource, the first frequency domain resource is a subset of a frequency domain resource corresponding to a first bandwidth part (BWP), and the first BWP is a dedicated. BWP of the terminal device. The terminal device receives a first physical downlink control channel (PDCCH) on the first BWP, where the first PDCCH is scrambled by using a group-radio network temporary identifier (G-RNTI), and the first PDCCH schedules a first physical downlink shared channel (PDSCH) within a range of the first frequency domain resource. The terminal device receives second indication information including a first frequency domain width. The terminal device receives the first PDSCH on the first frequency domain resource.

Abstract: A time domain resource determining method includes obtaining a group-radio network temporary identifier (G-RNTI). The method also includes detecting a first downlink control channel in a common search space. The G-RNTI is used for scrambling the first downlink control channel. The method further includes obtaining first time domain resource assignment information. There is an association relationship between the first time domain resource assignment information and the G-RNTI. The method additionally includes determining a time domain resource of a first downlink data channel based on the first time domain resource assignment information and the first downlink control channel.

Abstract: A first uplink channel is obtained to carry joint information of second uplink control information carried on a second channel and third uplink control information carried on a third uplink channel. In response to the first and third uplink channels meeting a first condition, the joint information is sent on the first uplink channel. Otherwise, the third uplink control information is sent on the third uplink channel. The first condition includes at least one of: (i) a distance between ending symbols on the first and third uplink channels is less than or equal to a first threshold, (ii) a distance between starting symbols on the first and third uplink channels is less than or equal to a second threshold, or (iii) a difference between coding rates of the first and third uplink channels is less than or equal to a third threshold.

Abstract: A communication method and a communications apparatus are provided. A principle of the method is as follows. Currently, for downlink data transmitted in a semi-persistent scheduling manner, only 1-bit acknowledgment information can be fed back in one time unit. However, as a transmission periodicity P of the downlink data transmitted in the semi-persistent scheduling manner becomes smaller, multi-bit acknowledgment information may need to be fed back in one time unit. In view of this, this application provides a communication method and a communications apparatus to feed back multi-bit acknowledgment information in one time unit. First, multi-bit acknowledgment information to-be-sent in one time unit is determined; then N acknowledgment codebooks are generated, where the N acknowledgment codebooks are used to carry the multi-bit acknowledgment information; and finally, the N acknowledgment codebooks are sent in the time unit.
