Abstract: This application provides a data transmission (including receiving and sending) method. The method includes: A terminal device receives downlink control information DCI, where cyclic redundancy check CRC of the DCI is scrambled by using a first RNTI, the DCI is used to schedule a first downlink data channel, and the first downlink data channel is scrambled by using a second RNTI; and the terminal device receives the first downlink data channel based on the DCI. The DCI includes a DAI domain and/or an FDRA domain. The DAI domain indicates a count of first HARQ-ACK information in a first HARQ-ACK codebook, and the first HARQ-ACK codebook corresponds to the first RNTI. The FDRA domain indicates, within a frequency domain range of a public frequency resource, a scheduled frequency domain resource on the first downlink data channel.

Abstract: A resource determining method and an apparatus are disclosed. A network device determines a resource of an uplink channel. A terminal device receives downlink control information (DCI) sent by the network device, where the DCI is carried on a physical downlink control channel (PDCCH). The terminal device determines the resource of the uplink channel based on the DCI, where the resource of the uplink channel is used to send uplink information. As a result, a latency of sending the uplink information is reduced.

Abstract: Methods and apparatuses for sending a multicast control channel are provided. One example method includes a terminal device receiving first configuration information, where the first configuration information indicates N modification periods, and N is an integer greater than 1. The terminal device determines, based on the first configuration information, a modification period corresponding to a first service, and monitors a modification notification of an MCCH based on the modification period corresponding to the first service. Therefore, in some instances, services with different latency sensitivities can correspond to different modification periods to meet latency requirements of different services and ensure an electricity saving effect of the terminal device.

Abstract: A communication method, and a communications apparatus. The method includes: a terminal device determines uplink information; when the uplink information is first feedback information, the terminal device determines a first uplink control channel resource corresponding to the first feedback information, and sends the first feedback information on the first uplink control channel resource; or when the uplink information includes A-CSI, the terminal device determines a second uplink control channel resource corresponding to the uplink information, and sends the uplink information on the second uplink control channel resource, where the first uplink control channel resource is different from the second uplink control channel resource. Therefore, a network device identifies, according to the control channel resource for the received uplink information, whether the uplink information includes the A-CSI, so that the uplink information can be correctly received without times of blind detection, and receiving complexity is low.
