Abstract: An entity establishment processing method and an apparatus are provided. The processing method includes: A terminal side device receives first indication information from a first network side device, where the first indication information is used to trigger reestablishment of a first PDCP entity of the terminal side device. When a first bearer corresponding to the first PDCP entity is not a radio bearer used to perform duplication transmission between the terminal side device and a core network side device, in a process in which the terminal side device reestablishes the first PDCP entity based on the first indication information, the terminal side device sets a parameter of the first PDCP entity to an initial value.

Abstract: This application provides a communication method and a communications device. The method includes: A first device receives a first message sent by a second device. The first message is used to indicate a bearer configuration of a bearer of the first device and an initial status of the bearer configuration, and the bearer configuration includes a first bearer configuration and/or a second bearer configuration. The first device determines the bearer configuration and the initial status of the bearer configuration based on the first message. According to the technical solutions in embodiments of this application, a bearer configuration of a terminal device and an initial status of the bearer configuration of the terminal can be indicated. Because both the bearer configuration of a bearer of the terminal and the initial status of the bearer configuration of the terminal are indicated, communication efficiency is improved.

Abstract: This application provides example data packet transmission methods and example communications apparatuses. One example method includes receiving a data packet, where the data packet is in an undelivered state. The data packet can then be delivered during running of a reordering timer upon an arrival of a first delay cut-off moment corresponding to the data packet or an arrival of a second delay cut-off moment of an additional data packet before the data packet in a reordering window.

Abstract: A method for handling a radio link failure (RLF) is described. The method includes sending, by a terminal device, duplicated data packets to a network device on a first carrier and a second carrier. Thereafter, upon determining that an RLF occurred on one of the first carrier and the second carrier, the terminal device sends RLF indication information to the network device. The RLF indication information indicates that the RLF event occurs on the first carrier, the second carrier, or the first carrier and the second carrier.
