Abstract: Embodiments of this application provide a data packet decompression method. In the method, the network side device receives a first PDCP data packet, decompresses the first PDCP data packet, and sends a first buffer data identifier to the electronic device if the first PDCP data packet fails to be decompressed, where the first buffer data identifier corresponds to buffer data used for decompressing the first PDCP data packet; the electronic device receives the first buffer data identifier, and sends first buffer data corresponding to the first buffer data identifier to the network side device, where the first buffer data is buffer data used for generating the first PDCP data packet; and the network side device receives the first buffer data, and decompresses the first PDCP data packet by using the first buffer data.

Abstract: This application relates to a communication method and apparatus. A first device determines to process a first radio bearer in a first processing manner. The first processing manner activates or deactivates a data packet compression function of the first radio bearer. Then, the first device sends first information, where the first information is used to indicate the first processing manner. The first device can send the first information to indicate to activate or deactivate the data packet compression function, which means that the data packet compression function can be deactivated.
