Data transmission method of physical uplink shared channel, data transmission method, terminal, network equipment and chip system

The invention provides a physical uplink shared channel data transmission method, a data transmission method, a terminal, network equipment and a chip system. In the application, a terminal receives indication information issued by a plurality of network devices, wherein the indication information is used for indicating a plurality of precoding precoders; the terminal determines a plurality of precoders according to the indication information, and uses the plurality of precoders to repeatedly send a physical uplink shared channel (PUSCH); wherein at least two PUSCHs (Physical Uplink Shared Channel) use different precoders. According to the method and the device, the PUSCH is repeatedly sent by using different precoders, so that the decoding performance of transmission is ensured, and the reliability of uplink transmission is enhanced. The uplink data repeated transmission technology provided by the invention can be suitable for a single-station transmission or multi-station transmission scene, and is also sui
