A wireless communication method, comprising: in response to determining that a data duplication transmission of a first bearer is deactivated and a split transmission condition is met, performing (S210), by a terminal device, a split transmission by using a first radio link control, RLC, entity and a second RLC entity in at least two RLC entities configured for the first bearer; receiving, by the terminal device, first information from a network device; and determining, by the terminal device, among more than two RLC entities of the first bearer, the first RLC entity and the second RLC entity for the split transmission according to first information, wherein the first information is used for indicating RLC entities among the more than two RLC entities that are used when the split transmission condition is met, wherein the split transmission condition comprises that an initial transmission data volume corresponding to the first bearer is greater than a first threshold, and wherein the first RLC entity and the second RLC entity are different, and comprise: the first RLC entity is a primary RLC entity carrying a master cell group of the first bearer, and the second RLC entity is a primary RLC entity carrying a secondary cell group of the first bearer; or the first RLC entity is a primary RLC entity carrying the secondary cell group of the first bearer, and the second RLC entity is a primary RLC entity carrying the master cell group of the first bearer. in response to determining that a data duplication transmission of a first bearer is deactivated and a split transmission condition is met, performing (S210), by a terminal device, a split transmission by using a first radio link control, RLC, entity and a second RLC entity in at least two RLC entities configured for the first bearer; receiving, by the terminal device, first information from a network device; and determining, by the terminal device, among more than two RLC entities of the first bearer, the first RLC entity and the second RLC entity for the split transmission according to first information, wherein the first information is used for indicating RLC entities among the more than two RLC entities that are used when the split transmission condition is met, wherein the split transmission condition comprises that an initial transmission data volume corresponding to the first bearer is greater than a first threshold, and wherein the first RLC entity and the second RLC entity are different, and comprise: the first RLC entity is a primary RLC entity carrying a master cell group of the first bearer, and the second RLC entity is a primary RLC entity carrying a secondary cell group of the first bearer; or the first RLC entity is a primary RLC entity carrying the secondary cell group of the first bearer, and the second RLC entity is a primary RLC entity carrying the master cell group of the first bearer. the first RLC entity is a primary RLC entity carrying a master cell group of the first bearer, and the second RLC entity is a primary RLC entity carrying a secondary cell group of the first bearer; or the first RLC entity is a primary RLC entity carrying the secondary cell group of the first bearer, and the second RLC entity is a primary RLC entity carrying the master cell group of the first bearer. <EOS>
