Abstract: A transmission method includes receiving first information from a first network device, receiving second information from the first network device, and transmitting the first data to the first network device based on the first information and the second information.
The first information is useable by the terminal device to divide first data into at least two data blocks. The first data is to-be-transmitted data between the first network device and the terminal device. A quantity of slots occupied by the first data is greater than 1. Each data block of the at least two data blocks is mapped to a different corresponding time-domain position. The second information is useable to indicate at least two modulation and coding schemes (MCSs) useable for transmitting the at least two data blocks, and the at least two MCSs are different from one another.-

Abstract: Example transmit power determining methods and apparatus are described. One example method includes determining a first transmit power based on N time domain resources corresponding to a first transport block. The first transport block is sent on the N time domain resources at the first transmit power. The first transmit power is a transmit power of the first transport block on each of the N time domain resources, a size of the N time domain resources is greater than one slot, and N is a positive integer.

Abstract: A communication method includes determining a third time unit and a fourth time unit. The third time unit includes all or a part of time units that are in at least one first time unit and that are used for transmission in a first transmission direction. A first signal is transmitted in the at least one first time unit in the first transmission direction based on a quantity of repeated transmissions. The fourth time unit is located after the at least one first time unit in a time domain, and the third time unit and the fourth time unit meet a requirement of transmitting the first signal based on the quantity of repeated transmissions. The method also includes repeatedly transmitting the first signal in the third time unit and the fourth time unit.

Abstract: Embodiments of this application provide a data transmission method and a communication apparatus. The method includes: A network device sends first information to a terminal device, where the first information is used to indicate transport block size TBS configuration information and/or redundancy version RV configuration information, the TBS configuration information is used to configure a first transport block size TBS, and the RV configuration information is used to configure first RV information. The network device receives a transport block from the terminal device, or the network device sends a transport block to the terminal device, where a TBS of the transport block is the first TBS, and/or RV information of the transport block is the first RV information. The network device may expand a TBS and/or refine an RV by using the TBS configuration information and/or the RV configuration information, thereby improving a spectral efficiency when the TB is transmitted.

Abstract: Embodiments of this application provide an information sending method, an information receiving method, and a related device. In the information sending method, a network device sends first signaling that carries first indication information, and the network device further sends second signaling that carries second indication information. The first indication information indicates a subset identifier corresponding to a first precoding subset in a first codebook. The first codebook includes a plurality of precoding subsets. Each precoding subset includes a plurality of precoding matrices, and different precoding subsets correspond to different subset identifiers. The second indication information indicates a matrix identifier corresponding to a first precoding matrix in the first precoding subset. Precoding matrices in the first precoding subset correspond to different matrix identifiers, and the first precoding matrix is used to precode a physical uplink shared channel (PUSCH) carried on a first subband.
