Abstract: This application provides a UCI sending and receiving method and a communications apparatus. In the method, an association relationship between a PUCCH and a PUSCH is established, so that when resources of the PUSCH and the PUCCH overlap, a terminal device can determine UCI on which PUCCHs can be transmitted by multiplexing the resource of the PUSCH. A network device may receive the UCI on the PUSCH. Because the network device may know in advance which PUCCHs and PUSCHs are sent to the network device, the network device can demodulate and decode a signal on the received PUSCHs, to successfully obtain UCI. The network device can make a proper decision based on the UCI.

Abstract: A communications method, apparatus, and system are provided. The method includes: receiving, by a terminal, configuration information from a radio access network (RAN) node, where the configuration information is used to configure precision of a multi-stage codebook, and codebook precision at different stages is different; and performing, by the terminal, reporting for codebook information based on the configuration information, where information about an Mth-stage codebook limits a range of an (M+1)th-stage codebook, and M is a positive integer and is less than a codebook stage quantity. The RAN node configures the precision of the multi-stage codebook for the terminal to enable the codebook precision at all the stages to be different, to obtain a more flexible codebook. In addition, information about a previous-stage codebook limits a range of a current-stage codebook, so that the terminal can perform codebook measurement and reporting within a specific range, thereby reducing reporting overheads.

Abstract: Example data transmission methods and apparatus are described. One example method includes determining an actual transmit power for first uplink data by a terminal device based on a determined channel transmit power and a transmission parameter. The actual transmit power is less than or equal to the channel transmit power, and the transmission parameter includes one or more of parameters that can be used to indicate a location of the terminal device. The terminal device sends the first uplink data at the actual transmit power. Therefore, the terminal device may determine the actual transmit power for the uplink data based on the channel transmit power and various transmission parameters that can indicate whether the terminal device is located at a cell edge, so that the actual transmit power for the uplink data can be flexibly adjusted.

Abstract: Embodiments of this application provide a downlink control information transmission method in which after receiving one piece of downlink control information (DCI), the terminal device learns whether blind detection of DCI needs to be continued. The method includes: A terminal device receives first DCI, where the first DCI includes first indication information, and the first indication information is used to indicate a first antenna port. The terminal device determines, based on the first antenna port and antenna port configuration information, whether second DCI exists. The configuration information may include an index of a CDM group to which each of a plurality of antenna ports belongs and a maximum quantity of CDM groups that is supported by the terminal device. Alternatively the configuration information may include one or more antenna port groups, and each of the one or more antenna port groups includes one or more antenna ports.

Abstract: This application provides a quasi co-location (QCL) indication method and a related device, and may be applied to coordinated multistation transmission. In the method, a terminal receives QCL indication information, where the QCL indication information indicates that time-frequency spread information of a demodulation reference signal (DMRS) is associated with time-frequency spread information of N tracking reference signals (TRSs) (or a TRS corresponding to the DMRS) and that delay-frequency offset information of the DMRS is associated with delay-frequency offset information of M TRSs.
