1. A data transmission method performed by a terminal, the terminal being configured with at least two antenna panels for uplink transmission, the method comprising:
receiving Physical Uplink Shared Channel (PUSCH) scheduling information sent by a network device, wherein the PUSCH scheduling information comprises first indication information and second indication information, and the first indication information is used to indicate a data layer comprised in a PUSCH, the second indication information is used to indicate a precoding matrix;
mapping, according to the precoding matrix indicated by the second indication information, the data layer comprised in the PUSCH onto at least two target antenna panels for transmission, wherein the target antenna panels are antenna panels, for transmitting the PUSCH, among the at least two antenna panels of the terminal,
wherein before receiving the PUSCH scheduling information sent by the network device, the method further comprises:
transmitting a beam-training signal resource using analog beams on the at least two target antenna panels;
acquiring a target transmission beam, indicated by the network device, corresponding to each of the target antenna panels, wherein the target transmission beam is acquired by the network device according to the beam-training signal resource;
transmitting an uplink signal resource, for acquiring channel state information (CSI), on each of the target antenna panels by using a target transmission beam corresponding to the target antenna panel, wherein the PUSCH scheduling information is acquired by the network device according to the uplink signal resource.
