Title:
DATA TRANSMISSION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/191781
Kind Code:
A1
Abstract:
A data transmission method and apparatus. In the method, an access network device first sends to a terminal device a paging message comprising a first indication; after receiving the paging message, the terminal device sends a random access preamble corresponding to the first indication to the access network device in response to the paging message; and the access network device sends a response message to the terminal device in response to the random access preamble, the response message comprising one or more kinds of information among timing advance (TA), uplink grant (UL-Grant), temporary cell radio network temporary identifier (TC-RNTI), and logical channel identifier (LCID), and downlink data. The response message that carries the downlink data and that is sent by the access network device to the terminal device may be understood as a second message (message 2, MSG2) in the random access process; which is to say that, in the embodiments of the present application, downlink data is sent to the terminal device in MSG2 so that the terminal device receives the downlink data as early as possible, which may reduce the data transmission delay.
