  • Publication number: 20220022155
    Abstract: User equipment receives at least one TAC that is broadcast by a network device, where the TAC includes geographical location information, and the geographical location information is used to indicate a geographical location of a preset location point in a TA corresponding to the TAC. The user equipment determines, based on the TAC and a tracking area list (TAL), whether the TAL needs to be updated. If it is determined that the TAL needs to be updated, the user equipment sends a tracking area update request to the network device. The user equipment receives a response message, of the tracking area update request, returned by the network device.

  • Publication number: 20220006566
    Abstract: Embodiments of this application provide a data transmission method and related device. The method includes: A receive end receives data from a transmit end; and sends a first response message to the transmit end at a triggering moment of a first preset condition. The first response message comprises acknowledgement (ACK) or negative acknowledgement (NACK) determined based on a channel quality evaluation result obtained by the receive end after evaluating channel quality of a first channel of the transmit end. The first response message is used by the transmit end to determine, based on the ACK or NACK carried in the first response message, whether to resend the data. The receive end may estimate the channel quality in advance, to predetermine a data receiving status before the data is actually received, and return the channel quality to the transmit end at preset moments. This effectively shortens a data transmission delay.
