A data transmission method, a PDCP sending entity, a network device, and a storage medium. The data transmission method comprises: obtaining a first SN value in a first PDU; if the first SN value is greater than a maximum value in receiving window range information of a PDCP receiving entity, generating a second PDU carrying a second SN value according to the receiving window range information and the first SN value; sending the second PDU to the PDCP receiving entity, such that the PDCP receiving entity adjusts the receiving window range information according to the second PDU, and the first SN value is within the range of the adjusted receiving window range information; and configuring an encryption and decryption algorithm and an integrity protection algorithm carried by the first PDU to be null algorithms, and sending the first PDU to the PDCP receiving entity in broadcast.
