Abstract: A method and apparatus for timing advance (TA) synchronization for uplink (UL) data transmissions are provided. A base station transmits a TA instruction to a UE. The TA instruction indicates one of at least two TA options. The first TA option indicates direct initial grant-free (GF) uplink (UL) data transmissions. The second TA option indicates indirect initial GF UL data transmissions with the UE initiating TA reference signaling for updating a TA parameter of the UE. The UE performs an initial GF UL data transmission to the base station based on the TA instruction.

The method for synchronizing an uplink ciphering parameter in unacknowledged mode includes: sending an indication message to a terminal when detecting that an unrecoverable error occurs in an uplink packet or that the uplink packet is invalid, where the indication message is used to instruct the terminal to initialize an uplink ciphering parameter; receiving a response message sent by the terminal; and initializing the uplink ciphering parameter according to an initial value of the ciphering parameter. The embodiments of the present invention solve a service defect, namely, a break of the communication link caused by synchronization of an uplink ciphering parameter between the terminal and the radio network controller in unacknowledged mode, and shorten the time of synchronizing the uplink ciphering parameter without interrupting the service.

Abstract: This application provides a method for processing timing advance (TA) of a terminal, and an apparatus. A terminal obtains a correspondence between first TA and a beam, determines, based on the correspondence, the beam corresponding to the first TA, and further determines, based on the beam corresponding to the first TA, whether the first TA is invalid. According to this application, the terminal may determine, by using a finer granularity, whether the first TA is invalid, and this helps trigger selection of more appropriate TA, thereby further reducing interference between uplink transmission.
