Efficient downlink control information transmission in mobile communication networks

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.

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.
